In the context of rising energy prices and the current energy crisis, how can the state, as part of a frugal energy policy, encourage and/or motivate citizens to manage the heating of their homes sensibly?
In my country, 25 million citizens are using district heating in their flats and houses (flats in multi-family buildings, housing estates, houses in the city heated by district heating plants).
Many people overheat their flats. The thermostats are set too high or, when there are no thermostats and the radiators are hot, instead of turning down the radiator some people open the windows and most of the heat escapes into the atmosphere outside the flat.
In view of the above, I address the following question to the esteemed community of researchers and scientists:

Answer
You comment on the lack of controls in buildings with district heating and high wastage; this is normal in the UK too (we have 2 cities with reasonably substantial DH). The problem in the UK is that the flats are mainly council (local government) owned and energy costs are part of the general rates that cannot be increased in some cases by law. Simple heat meters and heat charging would reduce the wastage, as would fitting better thermostats, but the councils seem to prefer to leave these properties alone and maintain them poorly. People are a far bigger problem than technology!!!

Which incentive instruments for energy saving and switching to renewable energy sources used in connection with the current energy crisis are more effective?
Which energy-saving incentive instruments and/or restrictions for not saving energy are already in place as part of the current interventionist energy policy in relation to the current energy crisis?
In some countries, energy-saving solutions are already in place or in the pipeline for a smoother transition of the economy through the developing energy crisis. These solutions include systemic instruments implemented by energy companies, local government institutions and incentives for citizens to use less electricity compared to the previous year 2021. Sometimes restrictive instruments are also used, i.e., for example, financial penalties for not applying energy-saving practices. However, among the incentives for citizens, incentives for citizens and/or companies are to be used in the upcoming heating season (autumn - winter 2022), such as a reduction in electricity tariffs if electricity consumption in the 2022 heating season falls by a min. 10 percent compared to the 2021 heating season. In addition, an incentive system for an environmentally, climatically and health-promoting change of energy sources by replacing dirty combustion energy sources with clean, green, renewable and/or emission-free energy should also be applied simultaneously with the energy-saving incentive system. This is also important in terms of taking care of the climate and the environment, and also with a view to air quality, which has an impact on the health of people living in a particular area, region, town, village, etc. At present, there are mainly financial incentive instruments for conversion to renewable and/or zero-emission energy sources based on government subsidy programmes to financially support environmentally friendly business ventures carried out in the framework of green energy development and/or reduction of energy intensity of buildings. As part of the reduction of the energy intensity of buildings, residential and other buildings are covered with additional layers of insulating materials and covered with new façades. In order to reduce thermal and/or electrical energy consumption, attics and roofs are also insulated and windows are replaced with more energy-efficient windows. Government financial subsidy programmes are being used to implement such energy-saving measures. However, the scale of financial support is limited and often insufficient in relation to needs. The issue of applying and improving incentive schemes for energy savings and switching to renewable and/or zero-emission energy sources is particularly important in view of the current energy crisis and also in view of the climate crisis, the scale of whose development and negative impact will increase in the coming years and decades. In view of the above, it is therefore urgently necessary to improve systemic incentives for energy saving and conversion to renewable and/or emission-free energy sources.
In view of the above, I address the following question to the esteemed community of researchers and scientists:
What instruments for energy-saving incentives and/or restrictions for not saving energy are already in place under the current interventionist energy policy in view of the current energy crisis?
Are energy-saving incentives or restrictions, penalties established for not saving energy a more effective solution within the framework of an interventionist, anti-crisis energy policy?
Which instruments of incentives for energy saving and conversion to renewable energy sources applied in connection with the current energy crisis are more effective?

With the help of which technologies can a commercial hydrogen production system and bank be created for the development of hydrogen energy?
Hydrogen production companies are to be set up in the European Union and a European hydrogen bank is to be established. This is necessary in view of the need to develop hydrogen energy. The development of hydrogen energy is one of the best solutions for a pro-climate and pro-environmental transformation of the energy sector and for increasing energy security, increasing the scale of energy self-sufficiency and reducing the scale of future, successive energy crises. Hydrogen power is one of the key types of emission-free energy sources. Consequently, the development of hydrogen energy is an excellent solution to carry out a pro-environmental transformation of energy, to develop green energy, to reduce CO2 emissions, to counteract the progressive process of global warming, to reduce the scale of the negative effects of a future global climate catastrophe that may still occur in this 21st century.
In view of the above, I address the following question to the esteemed community of researchers and scientists:

Certainly, hydrogen is the fuel of the future, and water is its almost unlimited source. However, I don't think one can safely store large amounts of hydrogen. Transporting it in liquid form is also not safe. But alternatives can still be methane, methanol and DME where there is not enough solar energy available.

If the pro-environmental and pro-climate green transformation of the energy sector had been fully implemented in previous years, would there not be the current (2022) energy crisis caused indirectly by the war in Ukraine?
In the country in which I operate, electricity and heat is still generated 3/4 on the basis of burning fossil fuels. However, if the current government had taken the pro-environmental transformation of the economy seriously, including the pro-climate transformation of the energy sector, and had been developing renewable and emission-free energy sources instead of blocking them for the past 7 years, then the current energy crisis would probably not be such a serious problem as it already is. Unfortunately, this has not been done. As a result, the energy sector in Poland is mainly dirty, combustion-intensive, high-emission, non-diversified. There is bad air in many cities. Coal-fired power plants use outdated technologies, coal is in short supply and imported. Similarly, other fossil fuels. Power grids not adapted to the current needs of the economy, etc. The development of renewable energy has been slow to materialise, as it has mainly been driven by grassroots initiatives of citizens who have, for example, installed photovoltaic panels on the roofs of their houses, solar water heating systems and heat pumps in their homes. Unfortunately, the scale of development of renewable and emission-free energy sources is still low due to barriers imposed by the government and the low level of subsidies supporting the green energy transition. The result is a low level of energy security and a high risk of a major energy crisis in the heating season, autumn/winter 2022.

Dariusz Prokopowicz,
It needs to be seen from two aspects. First, how to meet the gradual increasing demand for energy with the alternative (Alternative because we are talking about global energy needs to be replaced. Because of economics of scale for any new technology to mature and economic inequality amongst the countries to allocate a substantial part of their respective budgets towards the development of new technology it is not possible to implement any plan uniformly across the globe) source of energy capable of replacing the fossil fuel by the next century so the pace of development can be maintained. Second, while exploring the first there is a need to balance the carbon space availability which is steadily decreasing in the world and de-forestation needs to be arrested immediately. Now coming to your question, as Anna said, the situation would have been much easier but certainly not eliminated. And in all of these what is the most important around the world is the understanding the seriousness of the problem by the politicians who are clothed with all the authorities to draw the long-term plans. Now the biggest question is whether this political class is willing to learn and understand what is right for human existence in this world.

How will you reduce electricity consumption in a situation where electricity prices would rise by several dozen percent due to the development of the energy crisis?
It is already known that energy prices will rise due to the energy crisis. It is not yet known to what extent energy prices will increase. The question of this increase is determined by a number of factors.
On the one hand, there are objective factors such as changes in the price level of energy commodities on commodity exchanges. On the other hand, it is determined by the long-term national energy policy pursued to date (e.g. types of energy sources, development of renewable energy sources, diversification of energy sources and energy security) and by current social policy (subsidies and grants for citizens with the lowest incomes). A lot of data supports the thesis that the development of renewable energy and the abolition of dirty combustion energy monopolies are key ways of solving the energy crisis.
In view of the above, I address the following question to the esteemed community of researchers and scientists:
How will you reduce your electricity consumption in a situation where electricity prices would increase by several tens of percent due to the development of the energy crisis?
Or would you still have time in the near future, before the next heating season, to install new, renewable sources of electricity at home, etc.?

In the past, energy crises have initiated significant changes in the economy. For example, the commodity crisis (fossil fuel raw materials) of the 1970s resulted in changes in car manufacturing by replacing existing internal combustion engines with more fuel-efficient versions. At that time, the first media reports about climate change, the greenhouse effect, the progressive process of global warming and the crucial role of a civilisation based on classic, brown, combustion, unsustainable economics in this issue were deliberately ignored in the world of politics and business. Today, the level of society-wide pro-environmental awareness among citizens is already much higher. Much more airtime and publishing space is devoted to green economics and sustainability issues in various media. As a result, the current and future climate crises will perhaps become another motivating factor for accelerating the development of renewable and carbon-free energy sources.

Question

What are ways to save energy?
How can electricity and/or heat consumption be reduced?
How can electricity and/or heat be saved during the climate crisis?
An energy crisis is currently developing in many countries. In some countries, energy is still largely based on burning fossil fuels. Fossil fuel and electricity prices are now rising rapidly. Fossil fuels may run out in the coming autumn/winter season. In the country where I operate, the development of renewable energy sources has been slowed down over the past three decades. As a result, three quarters of electricity is still generated by combustion-based power generation based on burning fossil fuels. Therefore, now that an energy crisis has emerged and the scale of the climate crisis is gradually increasing, a problem has arisen. The risk of a deep energy crisis is high because the scale of diversification of energy sources is low, renewable and carbon-free energy sources are hardly developed and fossil fuel prices are rising. In addition, every year the government subsidises many billions of PLN to unprofitable coal mines and supports monopolistically operating power plants where this coal is burned. This is because the largest companies in the mining and energy sectors are government-controlled state-owned companies, and the employees of these businesses are important electorates for the government in parliamentary elections. These monopoly companies in the energy and refining sector have earned extra money from CO2 emissions rights trading, which, according to European Union guidelines, should have been used to support the development of renewable and emission-free energy sources. Unfortunately, the government did not allocate these funds to the development of renewable energy. In addition, the issue of diversification of energy sources has also been neglected by decision-makers, yet the issue of diversification of energy sources is one of the key factors of energy security. For example, plans to build the first nuclear power plant had already been in place for half a century in Poland. Several successive previous government teams planned the construction of the first nuclear power plant and, unfortunately, only these plans ended. At present, there is still not a single nuclear power plant in Poland and the rate of development of renewable and emission-free energy sources is slow due to the laws that have been in place for the last seven years restricting the development of renewable energy. This type of short-sighted, anti-social, anti-environmental, anti-climate, etc. energy policy has led to a situation where there is a high risk of a deep energy crisis. Citizens already know how serious the mistakes were made by the government in previous years in climate policy. Unfortunately, it will not be possible to rectify all these mistakes in a few months, to rectify the omissions made earlier, to build a nuclear power plant and to develop wind, solar, hydro, geothermal and the most modern and zero-emission hydrogen and fusion-based energy technology on a large scale. Consequently, the government offers subsidies to citizens for the purchase of more expensive hard coal and thus continues to support the development of combustion-based energy and also creates another pro-inflationary factor in this way. Citizens have therefore come to the conclusion that they have to deal with the energy crisis themselves. Consequently, one of the key questions that many people are looking for answers to is how can electricity and/or heat be saved during the climate crisis?

I very often analyze the economic cycles, in particular the long Schumpeter and Kondratieff cycles. According to many calculations, another upward rebound (recovery) related to the technological breakthrough should occur in the 2020-2030 decade. In my opinion, the events, turbulences in the world economy and politics of 2020-2022 that we are witnessing should result in groundbreaking consequences for humanity and, in accordance with the Kondratieff cycle, give a new development impulse. A particularly important factor accelerating the discovery and search for alternative fuels nowadays are very high price fluctuations and the limited availability of such fuels as crude oil and natural gas, which for some aggressive regimes have become a kind of international weapon and blackmail. In your opinion, what technologies, new types of energy will bring the transition to a higher level of civilization, or maybe save our world from a climate disaster and the destruction of humanity caused by pollution and climate warming?

We have now had over 30 years of doom-mongering about so-called AGW and yet the effects cannot be measured against the natural rebound from the LIA (that destroyed many countries for centuries). Far more important is to develop strategies to mitigate any effects of climate change, e.g. sea-walls and reflective houses. The population of the world will not develop on unreliable power sources.
Ultimately, fusion must be the goal, but that remains decades away.

In the current world energy scenario, the shortage of energy carriers and the low energy efficiency of industrial processes in Latin America have sharpened productive competitiveness in this region. In this context, do you consider that Small Modular Reactors (SMR) can be an energy alternative for Latin American nations? Please argue your answer. I really appreciate your collaboration.
Relevant answer
Answer
They certainly can, especially for those Latinamerican countries which already have experience with conventional nuclear reactors (Argentina, Brazil, and Mexico). Their main advantage is that they already have nuclear technology infrastructure, and the implementation of this new concept will be more accessible. Nevertheless, other countries without this experience can still benefit from the SMR concept. They can be more easily adapted to their national grid than the large Nuclear Power Plants, and the safety and non-proliferation requirements are less complex. In my view, SMRs can be a good energy alternative for many developing nations.

Non-renewable nature and environmental pollution toward the climatic changes are some disadvantages of fossil fuels (oil, natural gas and coal).
Hydrogen as a zero-emission fuel is a good solution to avoid the pollution. Ability of production of hydrogen fuel from the most available renewable energy, solar power (power to electrolyze) is a major encouraging point.
Trapping the countries in prize controlling authorities (OPEC) is another important reason to turn the hydrogen fuel.
However, risk of storage and handling is a major issue to be addressed when hydrogen is used as a fuel for general use.

Question

In a world where environmental concerns are stronger than ever, it makes sense to "clean up our act" across all industries including transportation, but biofuels will not be a good contemporary to electricity among other alternative fuels as it would exacerbate the "food vs. fuel" conundrum; we do not want to incentivize further environmental destruction. At the same time, we must also put our ways of doing so into consideration (e.g., mining for battery materials). I have mentioned the case for synthetic fuels as a complementary to BEVs in an article published on an aeronautics-themed issue on NAE's "The Bridge" (The article is the last one on the cover, and you can jump to it by clicking the article title "Putting Out Fire... with Gasoline? A Pragmatic Path toward Clean Fuels"). These types of fuels are already being tried in the aviation and maritime shipping industries, and is just getting ready for motorsport applications, but this also leaves us asking a big question: could they just be as viable for the transportation industry?
For the record, I acknowledge that BEVs will soon surpass internal combustion engine-powered vehicles in emissions, cost-effectiveness, range, and fueling time. For example, when we ramp up battery quality and production to be able to make solid-state batteries that could eventually provide thousands, if not millions of miles in range. However, we should also consider the ways ICEs can coexist with them yet have the upper handle, such as:
Maintenance: Yes, while BEVs/FCEVs have fewer moving parts than ICE-powered vehicles, the maintenance advantage for the latter is not what you think. It is natural for batteries to degrade, especially when used for prolonged periods of time, and experts recommend to only use between 20-80% of range to minimize the amount of stress put onto it. On the other hand, for ICEs, it is suggested to always leave the tank at least 1/4 full to minimize the likelihood of damage to the fuel tank and pump. While you could fully fill up your tank (as condensation could otherwise affect the lifespan of the fuel tank), it is not a good idea to "top it off," either. That is pouring a little bit more fuel into the tank when the pump cuts off, generally to round the cost of the refuel to the nearest dollar due to the risk of damage. Experienced truckers will only fill up to 95% full given that the fuel expands in heat alongside the risk of spillage and generally go no faster than 65 mph to maximize efficiency.
Accessibility: Suppose you are in a wildfire-prone area like California and a blackout affects your area. Before this happens, you may need to plan ahead as unless you have a generator or the like, you may be stranded while the gas stations hang on a little longer despite the increased traffic. Synthetic fuels would mean that environmental compliance would be just a retrofit away, and, in Porsche's case, the engines do not need modifications, either.
Fuel Economy in cold weather: I have seen conflicting reports on BEVs' fuel economy in cold weather. While many sources say that gasoline's drop is less than that of hybrids and BEVs (e.g., https://www.fueleconomy.gov/feg/coldweather.shtml), thermal management technologies, which can also be found in modern-day ICEs, can say otherwise, so it effectively depends on the battery/vehicle.
Availability of resources: To have as much as a resilient global energy supply as possible, we should not throw all of our eggs into one basket. While bidirectional charging, could, in theory, allow for a perpetual expansion of our electric grid, we must take the availability of resources into consideration, and must diversify our materials in case of supply bottlenecks. The second aspect mentioned above also falls under this umbrella, too.
In addition, we must also find ways to make the process of such synthesis of fuels much more efficient while at the same time bringing the cost down. This MIT-developed battery captures even atmospheric CO2 and is about to be tested at Porsche's synthetic fuel plant down in Punta Arenas at the extreme southern region in Chile's Patagonia: https://news.mit.edu/2019/mit-engineers-develop-new-way-remove-carbon-dioxide-air-1025 & https://news.mit.edu/2020/new-approach-to-carbon-capture-0709
However, most of the synthetic fuels about to be produced in a commercial scale are essentially made of recycled carbon so these specific types of fuel will be unviable in the long run. However, there seems to be room for improvement.
There is no doubt that EVs and alternative fuel cars are here to stay and will inevitably outpace traditional "ICE" engines in terms of sales and production, but when we take these advantages in consideration, how we could improve synthetic fuel to make production easier, cleaner and more efficient, and make it release as little emissions (CO2, NOx, etc.) as possible, if any? Oxy-fuel technologies? Technological breakthroughs once thought inconceivable years, months, or even weeks ago?. Maybe Porsche, BMW, Mazda, et al. could get some help.

Unfortunately, more and more data and research centers scientifically confirms that progressively progressing global warming has become a fact. First and foremost, human activity influences this. The impact of natural factors is significant, however, the progress of civilization, industrial development, greenhouse gas emissions in the past few decades has increased significantly and continues to grow. The biggest problem may be the inability to reverse this process even if all of the industry, energy and transport are now switching to renewable energy sources.
In view of the above, the current question is: Is it possible that man with the help of modern RES energy technology would stop the greenhouse effect on Earth?
Please, answer, comments. I invite you to the discussion.
Relevant answer
Answer
I am sceptical about the role of whether humans have actually the power to control the greenhouse effect on Earth, since neither RES nor greenhouse gases are humankind creations. Of course -in the context of the future development of (human) civilization- the anthropocentric technologies (in general, no necessarily the RES-technologies), carbon sequestration and greenhouse gas emissions, they can play a decisive role, but these actions are of definite power. The natural elements cycle and the environmental carrying capacity can be proven the most deterministic.

When comparing, for example, solar and atomic energy, many significant differences can be shown.
Solar energy is safer than nuclear energy. There are no environmentally hazardous radioactive waste in solar energy. In addition, solar power plants can be of any size, while nuclear power plants are usually very large investments and require huge financial outlays for the construction of a modern nuclear power plant.
But besides, many other energy technologies are being developed, energy innovations are being developed in the field of renewable energy sources, such as wind, water, or sea waves. In addition, geothermal energy and the development of energy storage technologies. This is an important issue because the consumption of electricity is growing in many developing countries. In the future, electricity consumption may increase even more when electromobility starts to spread, ie electric cars will be produced and sold on a massive scale.
In view of the above, I am asking you: Which type of energy should be developed in the future?

Smart grids are designed to:
1) Reduce the electricity demand load on the utility grid during daily peak demand periods.
2) Support renewable energy generation via distributed energy systems (DES) wind turbine farms, solar PV, concentrated solar power (CSP), and fuel cells stations.
3) Create independence of the utility grids in remote areas.
Accordingly, I'd say that market penetration by large-scale renewable energy systems relies on the presence of smart grids as well as distributed energy storage (DES) to offset the incompetency of renewable sources such as wind turbines, solar PV, CSP, etc.

I am currently researching the emission variations between agricultural land and energy crop cultivation. There is extensive literature about the argument of preserving agricultural land for food production and keeping energy crop production separate. This is primarily due to the increasing demand of food and decreasing available land for such agriculture.
My research has led me to the understanding that there are additional carbon emissions that need to be accounted for when calculating the environmental impacts of energy crops. This is due to previously stored carbon in the soils of uncultivated land, such as grassland, which is released once cultivation begins.
Is anyone working on or know of a study that has extensively calculated the emissions of both separate land uses and/or the variations between the same piece of land being used for agriculture and then converted into energy crops?

The attainment of sustainability requires adherence to some important aspects like human welfare, natural resource management, economic development, food and energy security and environmental sustainability. How Green Chemistry can address these concerns for a sustainable future of the planet Earth.
Relevant answer
Answer
The entire idea behind Green Chemistry is to be sustainable.  If it is called Green and it has no sustainability to the work then it is just a title and not really green..  I am a green building consultant and I see this in the green movement in building.  Every builder is now saying they are green yet they can not even define what is meant by the term.
This is unfortunate but the way of a capitalistic society.  If there is money to be made in the claim then the companies will claim what ever gets them to more profit.
We need to stop talking about how "Green" things are and start talking about how much better it is to be sustainable.  The term Green has been abused so much that most people think it is not real anymore.  I for the most part in my chemical research and in my green consulting talk about not just green but doing the right thing for our children and making a better decision today for a better tomorrow.  
I tell people that I refuse to make a decision today that in any way will jeopardize the lives of my children or make them clean up something that I have promoted.
Green is a movement to do better for the future and future generations and to stop being self centered and asses.  I am not perfect but if we all will just do what is possible we could change the world over night.
Green chemistry has to be the way we move to the future.  It must be more them just the word it must be real.

Let the spheres A, B, C and X be of a similar capacitance C. i.e.The difference in their capacitances is so small to be significant.
Bring the spheres A, B and C towards X so that the enclose it.
Momentarily earth the spheres A, B, C and X so that A, B and C each gain a net charge Q. Let the volumes of the spheres A, B, C and X each be V. i.e. The difference in their volumes is so small to be significant.
The charge density Z on X was,
Z = Q/V
The charge densities Z on A, B and C are,
Z = Q/V+Q/V+Q/V
Z = 3Q/V
The results show that the charge density of A, B and C charge system is higher than that which was on X.  This is possible because the electrostatic field on the outer most sphere is the vector sum of the electrostatic fields emanating from the charged inner spheres. So the charge density on the outermost sphere is more than that which was on the central sphere if we add the net and induced charges on the surface of the outermost sphere.
Therefore a higher charge density is being created at a certain point in space without as expending energy.
This is compared to crunching a group of like charges together without expending
energy.
This goes against the law of energy conservation.
