How would you design a similar or different futurological energy and civilization project, containing renewable energy sources of renewable energy and recreation of natural conditions, referring to natural ecosystems, which after years would gain the possibility of self-recreating?
For example, whether with unlimited investment funds or whether it would be possible to achieve a sustainable economic ecosystem from scratch to achieve economic efficiency at least at the zero growth level as follows: Can a large solar power plant be developed in the desert and water obtained from energy to develop agricultural production and plant ecosystems, including forest ecosystems, which, after several dozen years, could almost function themselves? An important factor would be the possible progressive climate change in a given area and the geographical scope of the area covered by this investment project.
In some science fiction movies there are scenes that suggest that it is possible, economically justified and real. However, the vision presented in science-fiction movies to create real projects can, however, be a very big difference. But many futurological visions that were created in the past have been implemented, so it is justified to undertake such attempts to create further futurological projects.
In connection with the above, I would like to ask you the following question: How would you design energy if you had unlimited financial resources? How would you design a similar or different futurological energy and civilization project, containing renewable energy sources of renewable energy and recreation of natural conditions, referring to natural ecosystems, which after years would gain the possibility of self-recreating?

Question

Has the classic economy lost its relevance to the energy market and therefore whether the process of necessary proecological reforms in the energy sector involving the replacement of energy sources, ie classic energy sources based on burning minerals for renewable energy sources should be coordinated by the state as a pro-environmental interventionist anti-crisis state?
Still at the end of the 21th century, in many publications written in the convention of classical economics, theses were formulated that energy should be shaped by the mechanism of market-harmonizing sides of demand and supply. However, this philosophy concerned classic energy based on the combustion of minerals. Mineral energy deposits in certain parts of the world are determined for several decades of extraction.
If the development of mining technology allows to reach and extract energy from deeper deposits than currently exploited and decks located under the sea and ocean bottoms, such estimated deposits would allow mining of these deposits in some places of the world for much longer than 100 years. However, humanity can not wait so much for pro-ecological reforms in the energy sector and the slow process of switching to renewable energy sources, which is happening in some countries, including the largest economies in the world, the largest emitters of greenhouse gases.
Currently, the philosophy of the energy sector is starting to change. Now the obvious issue is the need to quickly implement pro-ecological reforms without contemplating the depleted energy resources of the Earth's crust. This wait could take about 100 years or more than 100 years in many countries and this is too long, because at the end of the 21st century, according to climate change analysis, drastic climatic catastrophes will occur due to the predicted acceleration of the global warming process in the following decades.
According to the published and presented results of climatologists' research during the recent UN Climate Summits and Conferences on the problem of progressing global warming process, unless by 2030 at the latest the world will not show the classic energy based on the burning of minerals for renewable energy sources and motorization for electromobility and there will be no appropriate improvement of segregation waste and recycling, by the end of the 21st century, the average temperature at the Earth's surface will increase by 3-4 degrees Celsius globally, and the scale of climate cataclysms and weather anomalies will increase many times in relation to the current state.
In view of the above, the world can no longer wait for the depletion of energy minerals. This issue, which is particularly important for humanity and life on Earth, can not be left to the market mechanism and classical economy, whose philosophy has long been undermined, already in the period of the Great Depression of 1929-1934 it was demonstrated that Keynsovian state interventionism is needed to bring the economy out of the deep economic crisis if the liberalized private sector led to a crisis and the economy quickly does not return itself to balance and high economic growth on the basis of self-acting market mechanisms.
We currently have a similar situation. The world inevitably aims at increasing climatic cataclysms caused by the accelerating global warming process. these unfavorable processes for humanity and life on Earth will become a source of intensification of migration of people from subtropical areas, on which it will be impossible to live and live in a few dozen years due to high temperatures and droughts. In addition, there will be economic crises resulting from the global warming process. Humanity has no time to put off the necessary pro-ecological reforms for the future, these pro-ecological reforms in the energy sector need to be implemented now and it should be a process coordinated by the state in the context of pro-environmental anti-crisis state interference.
Do you agree with my opinion on this matter?
In view of the above, I am asking you the following question:
Has the classic economy lost its relevance to the energy market and therefore whether the process of necessary proecological reforms in the energy sector involving the replacement of energy sources, ie classic energy sources based on burning minerals for renewable energy sources should be coordinated by the state as a pro-environmental interventionist anti-crisis state?

Dear Dr Dinesh Pathak
Regarding the Renewable energies, it is really an interesting area that has been gaining more and more attention all around the world. However, some governments such as Brazil, China, India, few EU countries may be considered as advanced in the application of renewable energies technologies. As an example, the energy matrix of Brazil has 46% of renewable energy participation (in 2020), whereas the electrical matrix has >80% of renewable in the total share. Maybe the world will continue advancing into the development of newer technologies which will be considered even "cleaner" or "more efficient" in the future to come.

Question
10 answers
I have non-stationary time-series data for variables such as Energy Consumption, Trade, Oil Prices, etc and I want to study the impact of these variables on the growth in electricity generation from renewable sources (I have taken the natural logarithms for all the variables).
I performed a linear regression which gave me spurious results (r-squared >0.9)
After testing these time series for unit roots using Augmented Dickey- Fuller test all of them were found to be non-stationary and hence the spurious regression. However their first differences for some of them, and second differences for the others, were found to be stationary.
Now when I test the new linear regressions with the proper order of integration for each variables (in order to have a stationary model) the statistical results are not good (high p-value for some variables and low r-squared (0.25))
My question is how should I proceed now? Should i change my variables?
Relevant answer
Please note that transforming variable(s) does NOT make the series stationary, but rather makes the distribution(s) symmetrical. Application of logarithmic transformation needs to be exercised with extreme caution regarding properties of the series, underlying theory and the implied logical/correct interpretation of the relationships between the dep variable and associated selected regressors.
Reverting to your question, the proposed solution would be to use the Autoregressive Distributed Lag (ARDL) model approach, which is suitable for datasets containing a mixture of variables with different orders of integration. Kindly read the manuscripts attached for your info.
All the best!

I am conceptualising research into the impact of renewable energy consumption on green economic development. Various studies have adopted various approaches. What is most interesting that most if not all studies in this area relied on GDP as a measure of economic growth. GDP does not consider environmental and social issues that currently affect us.....What do you recommend?
Relevant answer
Answer
I agree with you, I had already concluded to adopt the same approach, I am now trying to think ways of enriching the study by adding a primary research as well. While it is all well and good to measure GDP per capita, it omits serious issues like economic activities that take place in remote areas, subjectively, one has to ask whose income? Renewable energy in Africa should have social economic impact particularly in places and local economies that operate in the margins of mainstream economy or urban areas. We should be talking increase in economic opportunities for the people whose economy was nonexistent, we should be talking entrepreneurship and innovation that has emerged as as result of renewable energy or electrification...............GDP can be distorting in a sense that can increase because of the improved productivity amongst the same old firms that depended on coal energy. Now, that for new is a problem. What are your thoughts

Question

The grid extension has long been the primary means of electrification of the region. However, connection to the grid is most of the time practically impossible due to geographical remoteness, thick jungles, rugged terrains, high costs of supply, low household incomes, low consumptions, dispersed settlement of consumers, and inadequate road infrastructures. As a result, decentralized diesel generators are most often used for rural electrification in the region. However, the high costs that are associated with the transportation of fuels and the maintenance of those systems make them unsuitable for rural electrification in developing countries. On a world basis, fossil fuel resources are experiencing a rapid depletion, resulting in an ever-increasing price which tends to make them unaffordable for developing nations. The growing evidence of global warming phenomena due to the release of greenhouse gases when burning those fuels is another critical reason for reducing our dependence on them. Therefore, finding alternative energy sources to meet the growing energy demand while minimizing adverse environmental impacts is becoming an imperative task.
Renewable energy sources, namely solar, wind, biomass, geothermal, and hydro, being inexhaustible, locally available, free, and eco-friendly can constitute potential sources of alternative energy, especially for local power generation in remote rural areas. Increasing interest has been given to their utilization since the oil crises of the 1970s.
The main drawbacks associated with the utilization of renewable energy sources are their unreliability and inability to work efficiently due to their intermittent and fluctuating nature, which generally leads to the over-sizing of the system, thereby increasing the investment cost.
How can hybrid renewable energy systems constitute a sustainable way for meeting the challenges of rural electrification in sub-Saharan Africa?

Question

Energy, especially electricity, has long been recognized as an essential commodity for everyday life in the contemporary world [1]. It is the main driving force of the human, social, and economic development of any nation. According to the International Energy Agency (IEA), the global electricity generation in 2017 was 25,551 TWh, of which fossil fuels (coal, oil, and gas) accounted for up to 65% [2]. However, due to their non-renewable nature, these sources are not likely to satisfy the increasing world demand in electricity resulting from the permanent growth in the world’s population and technological advancement. They are declining steadily. A study by Abas et al. [3] showed that oil, natural gas, and coal would be depleted in 2066, 2068, and 2126, respectively. This situation is the primary cause of the current price volatility and energy supply insecurity. Furthermore, the burning of fossil fuels releases toxic air pollutants and greenhouse gases (GHGs), which are detrimental to health and contribute to climate change. The consequences of climate change are far and varied, and include increased wildfires, prolonged droughts, stronger tropical storms, and frequent coastal floods [4].
What is the role of renewable energy in the global energy transformation?

Ecological innovations should contribute to accelerating the process of a global change in the strategy of civilization development towards sustainable ecological and socio-economic development. In the context of increasing greenhouse gas emissions, the ongoing global warming process, growing environmental pollution and the devastation of many environments and natural ecosystems, it is necessary to stimulate the development of eco-innovation and pro-ecological reforms in economic processes to implement sustainable economic and environmental friendly socio-economic development based on green economy concept.
Yes, it is necessary to change the development strategy based on intensifying the exploitation of the Earth's resources on the sustainable development strategy. It is necessary to develop new energy technologies based on renewable energy sources to slow down the progressing greenhouse effect of the Earth in order to reduce the risk of dramatic natural cataclysms. It is necessary to develop ecological innovations, while it may not be too late. It is necessary to save the Earth by extinction for future generations.
The 21st century is the last moment to introduce global sustainable development based on the development of renewable energy and ecological innovations. Sustainable development should be analyzed and measured in correlation with the analysis of economic growth and the share of individual sectors in the country's economic development, including the transformation of traditional energy sources into renewable energy, environmental reclamation and recovery of recyclable materials, and ecological innovations.

Most developing countries, particularly in Sub-Saharan African region rely on imported fossil fuels for their electricity, and for them to ensure that such electricity is affordable by their citizens, the governments subsidize the electricity tariffs. On the contrary, such countries have vast renewable energy resources such as solar and wind that have not been effectively tapped, mainly because of their high upfront investment costs that have hindered most of the people in these countries from using these resources. So, in case the governments revise their policies and instead of subsidizing fossil fuels, they apply these subsidies on renewable energy technology deployment, could this move be both economically and environmentally appropriate for these countries to consider as they endeavor to electrify their communities?

Answer
Welcome!
What do you said and thought in your question is right. Sub- Sahara African countries are rich in solar radiation and wind. So, they can exploit these renewable energy resources for clean electric generation.
There are now Gigawatt solar energy power stations based on photovoltaics. The cost of the construction of such stations becomes affordable and the cost of generating one Kwh is approaching that of the classical electric power stations.
The utilization of photovoltaic and wind may be obligatory in the future.

The problem is when the economically weak, small domestic economy has only traditional energy minerals, such as hard coal or lignite, and there are no developed different forms of renewable energy sources. In such a situation, there is a lack of financial resources for switching energy to renewable energy sources so as to move towards sustainable development according to the philosophy of the new, green economy, in order to limit the emission of greenhouse gases. The warming of the Earth's climate is already a fact and is a serious growing problem. Therefore, renewable energy sources should be developed. Rich countries should support countries characterized by weaker economy, lower incomes and based on traditional energy technologies. It is therefore necessary to strengthen international cooperation in the area of promotion, support and financing of investment projects, thanks to which it will be possible to develop renewable energy sources in the future and aim at sustainable pro-ecological development.
In view of the above, I would like to ask you: Why is there still traditional energy based on burning minerals in some countries?

What are the most serious problems of civilization development that should be solved as soon as possible? What are the global problems for which research should be developed and solutions to these problems resolved in 2019 and in subsequent years?
One of such research problems, which should not be postponed for an indefinite future, is the need to develop environment-friendly sustainable economic development in order to slow down the adverse process of global warming.
With the warming of the Earth's climate, the risk of more dramatic climate cataclysms, including tsunamis, increases.
Tsunami may be a derivative of the global warming problem. Global warming generates an increase in climate disasters, including more cases of tsunamis.
But not only is the risk of more violent and more dramatic tsunamis rising. Also in recent years, there has been more other types of climate and natural climate catatics, such as droughts, rainstorms, tornadoes and weather anomalies.
At present, it should no longer be asked whether global warming generates an increase in natural disasters only what rate of growth will be recorded in the future? So many data, research centers confirms the progressing process of global warming, that the problem is unquestionable.
More and more data points to the growing risk of climate change, unfavorable for human and life on the Earth, increase of climate disasters, climatic and weather anomalies, which are the result of global warming, rising average annual temperature near the Earth's surface.
Now we should just ask: How can these adverse processes be counteracted? What ecological technologies, renewable energy sources, how to help natural environments, how to rebuild them, such as afforestation, to build natural ecosystems absorbing greenhouse gases?
How to develop ecological business ventures? How to create financing systems for this type of pro-ecological projects? How to dispel international cooperation in this matter? What actions should be taken to move towards the development of a new ecological green economy?

Question

A significant part of the pro-ecological reforms as part of the transformation of the energy sector and the development of renewable energy sources is carried out by private companies.
However, these are usually undertakings not resulting from market processes only from changing legal norms established by the state administration.
In addition, the construction of large nuclear power plants, water plants and the type of large wind and solar farms absorbs huge financial resources with predicted relatively low profitability.
Therefore, private enterprises are not interested in investing in the development of large power plants that produce electricity under renewable energy sources if the state does not provide financial support under financial guarantees and a share in investment costs.
The development of electromobility in the automotive industry in some countries is also supported by the state to a large extent.
In some countries, the state from the budget funds of the central public finance system refinances a significant part of the costs of purchasing an electric car and finances the development of the necessary infrastructure of electric vehicle charging points deployed on the streets and arteries.
Therefore, the development of renewable energy sources, ie the key element of the pro-ecological transformation of the energy sector, should be coordinated organisationally and financially supported by the state.
In the context of increasing emissions of greenhouse gases to the atmosphere and the ever-faster global warming process, the pro-ecological transformation of the energy sector should be carried out as soon as possible.
It is not possible to implement proecological reforms in the energy sector and implement ecological innovations in other sectors of industry as well as wait for the resources of energy (hard coal, lignite, oil, natural gas) to run out.
This process can not be left solely to the market mechanism within the framework of classical or neoclassical economics.
In order for an environmentally-friendly transformation of the energy sector to be effected efficiently and as soon as possible, a significant share of financial support from the state is indispensable.
Do you agree with my opinion on this matter?

Renewable energy production methods available today can easily be invested into by those who might see return in it.
Instead of cofunding directly such investments, States should consider regulating and progressively ramping-out inefficient systems fit for out of date energy production methods.
An example is banning atmospheric engine vehicles within a decade.
Research into new energy production methods should be funded by States

Hydrotreating, hydrocracking, and distillation processes in Aspen Plus.
Relevant answer
Answer
Hello Pali,
I have previously simulated a hydrotreating process in Aspen Plus by using an R-Yield block ruled by a calculator block. I assumed a desired output based on the carbon yields for hydrocarbon species present in the hydrotreating product (see ) and calculated the required amount of fresh H2. The exported variables in the calculator would be the mass yields for each component in the hydrotreated bio-oil and the calculated H2 input.
Another feasible approach would be to assume a specific H2/bio-oil mass ratio (I've mostly seen on the literature a value of 0.04 with a 10x excess) and using an RGibbs block in which you would pre-define the feasible output compounds. In such case, you'd need to check the predicted output matches experimental or literature composition.
In the simulations reported by NREL and PNNL, they utilize an RStoich reactor in which they define a specific set of reactions, but in case you'd like to use that approach, you would need to exactly have your bio-oil defined with the same set of compounds they utilize. You can download the NREL biomass pyrolysis simulations in https://www.nrel.gov/extranet/biorefinery/aspen-models/ , which include the upgrading section for the bio-oil.
Hope you find this helpful.

Hello everyone
Are renewable energy certificates greenwashing?
What is the guarantee that solar cells that are depreciated are not harmful to the environment?
By increasing renewable energy production and promoting renewable equipment, there is a guarantee for their recycling after the life of renewable equipment?
Relevant answer
Answer
Hi Amir,
Renewable green certificates are one way to avoid double-counting, which might lead to greenwashing. Without them, the power produced might show up in the balance sheets of different stakeholders, all of them claiming that they have reduced their emissions.
Regarding depreciated solar cells: they do not emit harmful substances if they keep operating. Thus, it makes sense to keep using them as long as possible, and build new capacities to substitute fossil-based technologies.
Recycling: there is no guarantee, although some countries (e.g. in Europe) are passing laws to increase recycling of electronic equipment. It might not be economical at the moment to recycle, but it will be in the future when raw materials become scarce. Besides, it is a matter of sovereignty, because the critical materials are concentrated in a few countries. From an environmental point of view, it makes sense to recycle, but the environmental impacts of mining and extracting are usually not monetized properly.

There is no path to protecting the climate without dramatically changing how we produce and use electricity: nearly 40% of US CO2 pollution comes from power plants burning fossil fuels. Two-thirds of greenhouse gas emissions come from energy-related sources. This makes the transition to sustainable energy the decisive factor in tackling climate change. The utilization of renewable energy systems significantly reduces greenhouse gas emissions that contribute to rising global temperatures and reduces local air pollution and water contamination.

One of the best option to reduce climate change impact is the promotion of renewable energy. To protect global environment and reduction of GHG emissions promotion of alternative energy is essential. If we assume except GHG emission from renewable energy resources, fossil fuel combustion will be reduced in 0-10% globally our climate change burden will be stopped. So, can it will be possible handing together all nations to replace the fossil fuel combustion completely?
Relevant answer
Answer
I think it not possible to replace all fossil fuel combustion systems with renewable energy systems. First of all, most of the renewable energy system’s construction cost is comparatively higher than the conventional ones. Secondly, some of the renewable energy system (such as solar and wind energy system) depends on environment and weather conditions. So, it can not be able to provide a stable output throughout the day. Thirdly, it is too difficult to produce a large quantity of energy from renewable energy sources quickly.

This list is created in the Scopus database. Journals are ordered from highest to lowest CiteScore. The CiteScore numerator and denominator both include the same five document types (articles, reviews, conference papers, book chapters, and data papers) for consistency. This approach gives a more complete picture of citation impact and makes manipulation of the calculation more difficult.
Articles-in-press are indexed in Scopus for some publishers, but are not included in the CiteScore calculation.
Articles-in-press in Scopus are not processed in the same way as regular Scopus items. For example, in Scopus the cited reference list is not available for articles-in-press and therefore they do not contribute citations to other documents in the same way as regular Scopus articles. Also, Scopus does not receive articles-in-press from all serial titles and publishers.

In energy economics, many researchers consider calculating COE ($/kWh) considering capital costs, operation, ROI duration, and this is the minimum price at which energy should be sold, while others follow a different approach by calculating the net profit of selling energy and divide it by overall sold energy (kWh). Are these 2 values comparable?
Relevant answer
Answer
Hi Ahmed,
The COE/LCOE reflects costs that are intrinsic to the technology (investment costs, fixed costs) and to its role in the energy mix (variable O&M costs, fuel costs). Calculating the net profit would take into account these costs but also the volatility of the price in the market. I personally think the LCOE is easier to interpret, but I would use the net profit calculation if I want to convince investors despite a high LCOE compared to the literature / what they are used to.

The analysis of differences in the scope of Renewable Energy Policy in individual countries should take into account the scale of the share of the oil refining and refining industry in the entire national economy. The large share of the oil industry in the domestic economy may generate analogous large-scale lobbying of the industry on the government, on policies on shaping a specific direction of development of this sector in a given country. This lobbying may concern, for example, the deliberate slowing of energy sector reforms in the scope of pro-ecological needs. This type of conservative policy may not take into account the needs of reforming the energy sector, including the development of renewable energy sources, ecological innovations in renewable energy technologies, ecological material innovations, etc. The development of electromobility or the development of power supply technologies based on hydrogen engines should also be added to this issue. oxygen or other environmentally neutral technologies. Such reforms are necessary in the 21st century in connection with the need to reduce greenhouse gases in order to slow down the progressing global warming process, ie the increase of the average annual temperature on Earth. In the 21st century, it is necessary to develop a new green economy in the context of the forthcoming fourth technological revolution, known as Industry 4.0.
The issues of lobbying the oil industry to slow down energy sector reforms is one of the major problems of modern economics, specifically the issues of sustainable development with the emphasis on ecology, the impact of industry and classic energy sources on the natural environment. This issue is particularly important in the context of climate change, global warming, rising average temperature on the Earth, the progressing greenhouse effect of the Earth and the related new climate disasters is probably the most important topic for discussion, research and human action in the 21st century.

Protection of the environment, natural ecosystems and biodiversity should be an integral part of the concept of sustainable pro-ecological economic development?
In the context of growing and increasing environmental pollution and declining areas of natural ecosystems, the importance and need to improve environmental protection systems, natural ecosystems and biodiversity is increasing. Biodiversity is one of the most important issues of natural ecosystems and life on Earth. Maintaining high biodiversity on Earth should be a challenge and one of the main goals of human functioning on the Earth in the 21st century and in subsequent centuries.
In connection with the above, protection of the environment, natural ecosystems and biodiversity should be an integral part of the concept of sustainable ecological development. In some countries, the concept of sustainable pro-ecological economic development is implemented successively, primarily in the field of renewable energy sources, improvement of waste segregation techniques and recycling development. However, in many countries these issues are still insufficiently developed.
Still too small financial resources are allocated in many countries for the development of renewable energy sources, improvement of waste segregation and recycling techniques. In addition to the private sector, besides enterprises implementing ecological innovations, it is necessary to increase expenditures and develop strategic pro-ecological reform projects, including restructuring of the mining industry of minerals supplying classic energy sources and development of energy based on renewable energy sources. This development should be supported and coordinated by environmentally friendly state intervention, and due to the high investment costs of construction of power plants producing electricity from renewable energy sources should be co-financed from the state public finance funds.
In this way, it will be possible to slow down the ongoing global warming process in the 21st century and thus slow down the process of devastating the natural environment, draining green areas characterized by high biodiversity. Biodiversity is a very important issue in the context of the analysis of ecology, sustainable development and the protection of the natural environment, including, in particular, the natural positions of biologically complex ecosystems, i.e. those that are characterized by high biodiversity. Maintaining biodiversity of natural ecosystems is one of the most important problems and tasks for people in the 21st century.

Fossil Fuels and Global Energy Demand:
Do we have a breakthrough in the development of renewable energy sources? If not, what will be the approximate fraction of the global energy demand that will be supplied by oil and gas in the next few decades?
To what extent nuclear energy and solar renewable energy would really hinder the growth of oil and gas firms?
Whether the projected growth of solar, onshore, offshore, wind and hydro energies would really make an impact in meeting the global power generation of approximately 30,000 TWh by 2030?
Whether the energy demand for the sustained economic growth of the increasing global population can afford to ignore fossil fuels citing its contribution to the so called anthropogenic climate change? Will it be feasible in practical sense even by 2030?
With an expected global electricity consumption of nearly 30,000 TWh (terawatt-hours) by 2030, will it be really feasible to suppress the oil demand well-below 200 million tera-joules by 2030 anticipating that the natural gas demand and coal demand will not exceed 150 million tera-joules (individually)?
While oil and gas have not yet peaked yet (probably by 2030 for oil and 2040 for gas), and with the expected power consumption of nearly 60,000 TWh by 2050, have we really started ignoring the fossil fuels citing the anthropogenic climate change or is it just a momentary fall of fossil fuel demand due to COVID19?
Whether the climate change problem will remain solved just by sidelining fossil fuel consumption? Will the global annual CO2 emission will be reduced by 50% by 2030; and say, to 80% by 2050 (from its current level of emission: nearly 35 Gt CO2 per annum) – just by suspending the fossil fuel consumption?
Relevant answer
Answer
The concept that nuclear energy or solar or wind competes with oil & gas is an apples and oranges argument. Nuclear, solar, and wind, along with coal are strictly sources for utility electric power. Oil is used for mechanical power for transportation via gasoline, diesel, and jet fuel. The only competition overlap is natural gas, and currently natural gas is extremely abundant and extremely cheap, basically the same dollar amount it had in the 1960's at under $3/MTBU. Both oil and gas are vital for plastics and chemicals which is why even if they are artificially prohibited for energy, they are valuable as a material. Oil may be economically recoverable for 100 years as there are large areas of both conventional and shale undiscovered. Natural gas worldwide has 200 years to go. Both solar and wind have a physical limitation most advocates ignore, the material required, especially rare earth elements, to completely replace mechanical power with electrical power for transportation is also finite. Manufacturing all the solar cells and batteries will require a lot of hazardous chemical processing for both the initial devices and to recycle them and all will quickly deteriorate with heavy use. Wind turbines also have a limited life as the mechanical generator wears and the entire unit must be replaced with fiberglass blades that are not recycled, but are currently buried in landfills. Not the nirvana solution they seem to be. That leaves nuclear as the final stage of the energy evolution option, and this means new nuclear technology, like thorium reactors, breeder reactors and eventually fusion. Even fusion must evolve from radioactive neutronic reactors to non-radioactive aneutronic reactors. There is a lot of work ahead.

Humanity has reportedly only had a decade of time for the necessary changes in the energy sector to avoid a global climatic catastrophe
Much has to change in consumer awareness, business must change and different social groups should force policies and change legal regulations. It is necessary to develop co-financing of investment projects in the field of renewable energy sources by the state from public funds. In addition, businesses must see this business. The development of renewable energy sources should be profitable, and it is not because it is cheaper to mine minerals, to devastate the natural environment. It is cheap to run classic energy based on mineral combustion because this classic energy and mining industry of hard and brown coal, oil refinery industry, automotive industry of vehicles equipped with internal combustion engines etc. is not burdened with the costs of natural environment devastation, costs of treatment of people who suffer from due to poor air, smog and no negative effects of global warming. If the mining, energy, processing and automotive industries were burdened with these costs, then it would not be worthwhile to devastate and pollute the natural environment. Then it would be more profitable to develop energy and industry based on renewable energy sources. Inventions of electricity have over 100 years of history. 100 years ago, electric cars should be produced, but the oil business this scenario of more sustainable development has crossed out. Therefore, for over 100 years, archaic energy based on the burning of minerals has been developed. During these 100 years, the average temperature of the Earth's surface has increased by 1 degree ° C. From specific scientific studies, it appears that humanity is only 12 years left to make the necessary changes, to switch energy and industry to renewable energy sources and the automotive industry to electromobility, to reduce poor quality of stoves and domestic ovens, on the development of large and small, home solar, wind and other power plants. At the same time, investment projects in renewable energy sources should be widely developed and entire economies should switch to sustainable pro-ecological development according to the concept of a green, new economy. If during this time these changes are not implemented then the average temperature of the Earth until 2030 will increase by another min. 1 degree ° C and then in the following years the greenhouse effect will accelerate and the problem of global warming will become an irreversible process, which will mean the widespread apocalyptic climate disasters covering most of the Earth's surface before the end of the 21st century.

Sustainable development is very important in the context of the increasing use of resources and environmental pollution.
The basic issue that must be achieved within the framework of full sustainable development is the renewal of resources, reduction of economic growth to the optimal level ensuring renewable resources, reduction of environmental pollution, creation of biodegradable substitutes for fossil fuels, replacement of traditional energy based on mineral combustion for technological innovations in in the field of energy, including the development of energy based on renewable energy sources, etc. To this should be added a reduction in greenhouse gas emissions to slow down the negative aspects of the oceogenic climate of the Earth. There is so much to do in these themes and, above all, a great deal to do in the 21st century so that it would not be too late.'
To effectively carry out this process, it is necessary to develop universal, precise measures of sustainable development that will be used globally and will be recognized as the standards for assessing the process of achieving and achieving sustainable economic development in harmony with ecology.
But it is very difficult to establish precise measures for the sustainable development process. Sustainable economic development in correlation with ecology should be measured to determine if it is being implemented. It is necessary to define precise determinants that on one hand will determine the pace of economic development and on the other hand will take into account specific issues of ecology. It should be a set of quantified indicators based on selected measurable and quantitative data, so that the whole analytical process can be considered as a research objective method. The best solution will therefore be to develop an analytical scoring method, for which the basic components of this method will be defined economic and ecological quantitative indicators.
In the light of the above, the question arises: Is sustainable development possible taking into account the full harmony of economic development with ecology?
Even if it is unrealistic, what are the reasons for building a theoretical model that would present such a fully balanced development?

The literature surrounding oil price impact on an index mostly uses a VAR model. (Abhyankar and Wang, 2008) (Papapetrou, 2001) (Park and Ratti, 2008)
Rarely a VECM model is used. (Lanza et al, 2004) (Hammoudeh et al, 2004)
I have once seen a regression calculation but can't find the explanation for it (Gupta, 2016)
Due to renewable investment of individual companies only being available in news events or annual reports I am unsure which method to follow.
Is using a VAR model for monthly Oil returns, monthly O&G company index returns, and a dummy variable for renewable investment events in the news a possibility?
I would also be open to splitting my question into 3 sub-questions if this makes it easier to apply methodology.
How does oil price impact UK and US market index?
How does oil price impact the stock price of public oil and gas companies?
How does renewable investment impact the stock price of oil and gas majors?
I would also like to ask if a correlation coefficient can be used or simple regression analysis to establish a relationship?
Any help and advice would be highly appreciated.

Stocks are financial series. In addition to this, financial series contain volatility clusters. Therefore, financial time series methods (volatility models, fractal analysis etc. ) that take this into account are appropriate.

Humans are the largest pest ever seen on Earth. How do we think (we must do something) after terrible mass extinctions, trilobites, dinosaurs(are we the next dinosaurs?) we are almost "to blame" when knowing the Earth's permanent recycling but still continue to use up resources (like buring the dead) or petrol or coal, it will one day end, it has been speeded up by humans, we think there has been life on Mars, we still say it is us, we use resources, (we may not replace them), the Earth life will end... But a meteorite could end with the dinosaurs life (or the trilobites)?

Answer
During the coming decades, the current trend to reduce the use of fossil fuels, particularly coal and oil for electricity generation, will continue, and at the same time increase the participation of the various renewable energy sources in the energy matrix of many countries. However, the use of fossil fuels will continue to play a relevant role in the energy mix of many countries at least until 2050
The use of nuclear energy will be a viable alternative for at least more than 30 countries with an increasing role of this type of energy source in the Asia-Pacific region. Nuclear fusion reactors are viable experimental projects in the process of design and implementation. They will be used to generate energy from the thermonuclear fusion of confined ions by implosion or by magnetic fields. Some international organizations are studying and developing different technologies necessary to carry out thermonuclear fusion power plants' construction in the future. The most important experimental models began to be put into operation from the first quarter of a century. It will be then when the different reactors demonstrate their capabilities in an ecological context. As of the year 2050, if the research work being carried out is completed, the construction of fusion power plants all over the planet will begin. The necessary reserves of deuterium and tritium used in this type of power plant are practically inexhaustible. Nuclear fusion is expected to play an important role in a group of countries' energy matrix after 2050.
In turn, a greater use of hydrogen for power generation is expected around 2050. Hydrogen is considered one of the most important energy sources of the future. Because of the scarcity of energy resources, hydrogen applications already offer a real technological alternative to conventional solutions. The best example is the fuel cell. In fuel cells, hydrogen and oxygen combine to form water, releasing a large amount of energy. In this way, fuel cells can be used in vehicles as an ecological alternative to the conventional combustion engine.

Is there any direct relation or equation between the open circuit voltage and the instantaneous voltage produced at the output of the PV panel at a particular irradiance and temperature value?
Relevant answer
Answer
There is a misconception that because a voltage source isn't connected to a circuit or load, the voltage doesn't really exist, or its power doesn't go into effect until it is connected to a closed-circuit path. However, this is erroneous.
A voltage source does not need to be connected to anything for voltage to exist. Voltage unconnected is the real voltage. Even if a voltage source is unconnected and not attached to any load, the potential power still exists.
This misconception may stem from the fact that current can only flow when it is in a closed circuit. However, voltage is different. While current can only exist when a circuit is closed, voltage always has potential.

The key issue is interventionist support for the development of these pro-environmental investment projects implemented under public-private partnerships or by fully commercially operating economic entities, which in the coming years will become profitable and / or will contribute to the increase in the scale of sustainable development and pro-ecological transformation of the economy. with the aim of transforming the classical social market economy as much as possible into a circular social, sustainable, green economy. It is a formula of the ideal model for the development of civilization in the twenty-first century, which may never be 100 percent. achieved, but due to the ongoing processes of climate change, the global warming process and environmental pollution should be developed as much as possible.

Could the "incoming solar radiation" values be negative?
What is the difference between "global solar radiation" and "incoming solar radiation"?
Which one might be measured negative values?
Relevant answer
Answer
That diagram seems to be showing net incoming radiation, not incoming solar radiation which is always positive or zero. The negative values occur during the winter when the only radiation is outgoing thermal IR radiation from the snow and ice.
Note incoming solar radiation, ISR, is incoming shortwave radiation, also ISR. I suggest that the diagram is showing net radiation which is !SR - OLR (outgoing longwave radiation.

The hourly load curves of the selected household in each season are shown in Fig. 28.
Figure 28 shows the demand for electricity in four months on an hourly basis. Can you explain this diagram to me, is this the average consumption curve for one day or the total consumption of days in a month summed up in specific hours?
Figure 28 is attached to the question
Relevant answer
Answer
The values of the electricity consumption is given per hour averaged on the whole month. So
Mathematically Average hourly consumption along one month of the year=
SUN one hour consumption in kwh from day one to the end of the month. divided by the numbers of days in month. January is the highest consumption may be due to heating. Some hours in the summer days the consumption increases because of air conditioning at the nun times.

Power-to-heat (P2H) shows how we can use renewables for heating. Power-to-heat technologies have been on the market for quite some time now, with heat pumps being the most important. However, they are only efficient at lower temperatures. Whenever very high temperatures are needed – for example, in the industry – electrode boilers are used.
So what do you think? Which technologies do you think will substitute the current fossil-fuel-based heaters in the future European energy system?
Relevant answer
Answer
I think the major source will be direct solar heaters. Especially in the European countries in the south and east of Europe where they are rich with solar radiation.
For very controlled heating for industry one has to use the photovoltaic generators.

In Bangladesh, the proved reserved of natural gas 34 TCF which will lead the country next 20 years and currently 82% natural gas consumed in the power sector for power production. Whereas only 3% of electricity produced from renewable energy sources. However, there is an immense interest in using renewable energy like solar, biofuel, geothermal, wind due to environmental and economic concerns [Uddin et al. 2019].
Do you think Bangladesh can do it in the long-term, for example in the year 2100? If "yes", how? If "No", why?
Relevant answer
I am not very aware of the availability of land for solar power installations in Bangladesh. The interesting with the increasing the solar cell conversion efficeincy, the area required will be reduced. The other important factor is increasing the utilization effeciency of the electricity by smart control one may reduce required electricity supply.

The evolution of the distribution of electrical power both in the short term and in the long term.
Relevant answer
I do not think that the energy will flow in bidirectional manner. It is only the data collected by smart devices that can be made to flow in bidirection. This is called full duplex communications.
May be the most advancements will be the more smart control of the power sources and the power consumed by the loads to increase the utilization efficiency.
Also because of the wind and PV generators with the distributed nature brings with it the transformation from strictly centralized electricity generator to hybrid distributed system.

With coal mines still being planned and opened with 30-40 year lives, is coal seam gas (CSG) a real clean option or is it just as dirty as coal for our global power stations? Most CSG wells have lives of up to 15-25 years. When are we going to take other energy sources, such as solar and wind seriously? Can they be taken seriously as the petroleum industry buys shares into renewable energy sources and places them on the back burner until expensive lead in costs for coal and gas mines and wells can be recouped?
Relevant answer
Answer
CSG - 'natural gas' burns cleaner but has a much greater, though hidden, impact on groundwater and surface water systems, particularly life dependent aquifers. It is highly combustible. It always surprises me that more people don't kill themselves and their families when using it. By the the by hydrocarbons, such as the BTEX group still used in fracking, is extremely carcinogenic.
