Questions related to Renewable Resources
Dear researchers, what are the proposed methods to optimize battery SOC and diesel fuel usage , as an energy management strategy for off-grid microgrids ?
Such system are exposed to uncertainty and high penetrations of renewable resources.
In order to effectively promote the issue of natural ecosystems in the context of developing models of sustainable development, it is first necessary to develop an information program that will act as the content of specific social campaigns conducted in various types of media, including new media, also on social media portals. Both social information campaigns should be conducted on a large scale. In addition, there should be successive changes to the law, ie new legal regulations that will motivate the transformation of business models towards the development of green economy and sustainable development. These campaigns should also motivate research centers to create new ecological innovations and new technological solutions in the field of renewable energy sources.

Recently, discussions have been held in the public debate on issues related to the development of the green economy concept, the need to introduce pro-ecological policy reforms, etc. to make it possible to achieve globally sustainable pro-ecological economic development in the perspective of the next years.
In the context of the problem of determining determinants of sustainable pro-ecological economic development, the following question also appears:
How should the new economy be developed in accordance with the green economy concept in the field of renewable energy development by means of which instruments and reforms of green energy policy, so that it is possible to achieve globally sustainable pro-ecological economic development in the perspective of the next years?
How effective green economy philosophy should be developed in a pro-environmental energy policy in order to solve key development problems of human civilization, ie environmental pollution, effective and quick to reduce greenhouse gas emissions and thus slow down the global warming process , activation of the development of electromobility, development of modern non-emitting harmful waste to the environment, renewable energy sources, development of organic agricultural production, development of biodegradable packaging production, etc. with the use of electricity produced from renewable energy sources?
Therefore, I am asking you the following questions:
How should pro-ecological energy policy be developed according to the green economy concept in the field of renewable energy development?
How should programs for the development of renewable energy sources be financed?
Should the state co-finance, within public-private partnerships with public funds, large investment projects for the construction of power plants producing electricity based on modern technologies of renewable energy sources?

I would like to do my PhD on the climate change. If anyone is willing to work with me, we can connect and I can explain the whole theory and then may be we can proceed quantitively to prove my theory is right or wrong.
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?

What kind of scientific research dominate in the field of Renewable energy sources?
Please, provide your suggestions for a question, problem or research thesis in the issues: Renewable energy sources.
I invite you to the discussion
Kindly suggest some upcoming research areas/ challenges to explore in (but not limited to) sustainable planning, and performance assessment of hybrid renewable grids.
Recently, several inventions for the electricity-drived N(2)-fixation & CO(2)-assimilation have been reported (Liu et al., 2017; Lu et al., 2020 - see added files). Also, there are many physical, chemical, and biological inventions for removal of dissolved phosphorus from the natural waterbodies and waste waters. However, most of them require large technical buldings or significant expenditure of organic matter (in case of enhanced biol. phosphorus removal) or other forms of energy. On my opinion, it would be perspective to elaborate artifical compartment, made with the membrane coupled with phosphate transporters. As well as in case of artificial nitrogenase in Liu et al., 2017 & Lu et al., 2020, P-transporters would be supplied with power in form of electricity. I anticipate these systems would be more energy-efficient. Such artificial compartments would provide the phosphorus accumulation from natural waterbodies, rich in P, but pure in dissolved organic matter. It would be the potential alternative for the conventional obtaining of phosphorus from the rocks of Earth's crust.
Renewable energy sources based on solar energy belong to those types of renewable energy, which should be developed in the next years in the energy sector, because it is the production of clean energy.

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.
The topics related to the greenhouse effect on Earth, which are the subject of discussion, are particularly important and scientifically important and in the context of human life.
In the context of this issue of lobbying of the oil industry affecting the governments of countries, there is an important issue for discussion in the field of economic development of the world in the 21st century.
Therefore, I am asking you with an important question: Does the issue of oil industry lobbying affecting national governments in order to slow down energy sector reforms be a serious problem and a brake on pro-ecological reforms in the energy sector and the development of, for example, electromobility?

Why “roadblocks are often been overlooked by forecasters” before moving to the “prediction system (PS)”? Can it (PS) be considered a sustainable in the long term?
Now a days most of the forecasting agencies in India are busy in giving seasonal weather forecast (regional) including extremes and making it instantly available on the net. Many are in race of launching new portal to do so without comprehension of the predictability charade. Mostly been done using numerical modelling systems without exploring (disclosing) the some main factor which are essentially are the roadblocks in predictability.
I think, correcting spatial bias via embedded station data network should not only be the focus, though it will be a help but not sustainable solution. Why main problem lies been often overlooked before moving to PS? For example- intraseasonal variability (main roadblock to the predictability) is not well resolved in GFS forecasting model (or alike other models) and these oftenly used by the forecaster as an input data to their chosen prediction model. My question is, if unresolved or inadequate in specific sense (exam.- not having tendency to reproduce intraseasonal signals) inputs goes into the main predictive model then how sustainable will be the forecast in the long run. I feel, to do any less may result in prediction unsustainable. Surely, it may results in few right prediction and leads to self-acclaimed commendations but in longer run chances of failure in prediction will be higher. In terse, these prediction will have no substantial value in the long term.
For example – in a year when these charade processes will be predominant, forecast will be failure and it leads to socio-economic loss and setback to forecasting organizations. In general it will then, as usual, follow with post-mortem which will again highlights the need in the improvement of microphysics, intraseasonal signals variability, lead lag relationship, issues associated to AWS, standards rules or norms, installations, implementations policies, and money etc. aspects and in some cases probably leads to blame game to defend the failure. Remember, these reasoning to defend the prediction sometimes makes other agency competitive and robust. Healthy criticism can substitute constructiveness. I think, scientific failure must be constructively accepted to explore afresh scientific causes behind instead politicization.
If such things continue then it will be followed with actions such as --- Despondent with exiting forecast, Govt. decided to search for new options, leaving or updating the existing.
I think, Obliviousness should not a substitute for decisive forecasting. Forecasters must ensure that all roadblock are properly addressed or informed properly to tackle forecasting related failures and contingency. The truth must not left to postmortem and implications of the words.

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?

Hello Dear Researchers,
Given the potentials, and environmental and economic issues in the field of renewable energy, which type of biomass source will be environmentally and economically superior in the future; Forest Biomass, Herbaceous Biomass, Aquatic Biomass or Manure Biomass?
Is it feasible to replace my Photo Voltaic (PV) solar panels system by Solar Water Heater (SWH)?
Our group need to start giving topics on which one should we focus on regarding non renewable resources. I've looking these past 2months but nothing comes to mind.
Hello, I'm studying the potential of the renewable resources in power generation and I was wondering how can I calculate levelized cost of energy (LCOE)?
Climate change, including global warming, are some of the biggest challenges facing humankind today. Human activities are mostly responsible for global warming because of their role in increasing greenhouse gases (carbon dioxide, methane, nitrous oxide, and fluorocarbons), a heat trapper in the atmosphere. Among the mentioned gases, carbon dioxide is most devastating in terms of the global warming scenario. The Earth’s surface temperature has warmed in the last 100 years, and there is no credible hypothesis for this, other than the net effect of greenhouse gases (especially CO2).
Keeping the average rise of global temperature below 2oC (whereas concentration level CO2, lower than 550ppm) has become the focus of international efforts formed notable in the Copenhagen climate change conference (2009). And indeed, since then, we are seeing the room to tackle the global warming issue by promoting a dialogue based on policies and strategies, including adaptation, mitigation, and sustainable growth perception through the use of renewable resources for the well-being of humanity. The former statement on tackling the climate is reasonably fine and considered as the sustainable way to handle the global warming issue. But you might have noticed that there are several shortcomings in the way (for example- the world political leaders cum the policy makers have their own probable constraints and visualization) of sustainable growth based on policies and strategies. We cannot rely idea which country is doing good and which is not in holding the promise to curb CO2 and including many other such concomitant factors associated with policy making.
Keeping this as a base I suggest if we may share our views on the possible scientific approach to reduce dangerous anthropogenic (CO2) in the atmosphere other than that based on policies and strategies encompassing adaptation, mitigation, and sustainable growth (an incessant constructive growth) through the use of renewable resources. May you all please think about it and write down the likely scientific possibilities (a way to handle the problem scientifically rather than policy making) and suggestions to curb CO2.
Happy World Environment Day (05 June).

Increasing use of solar renewable resources or farms on weak remote locations are causing significant power quality and voltage notch issues with connecting utilities. High penetration of these resources are increasing the sensitivity of these interconnection issues at the PCC, point of common coupling. There are many sync. close techniques but these are complicated and require single phase closing devices along with complicated expensive controllers. Why are pre-insertion resistors not commonly used?
Hey guys in a lab setting, chambered experiment in a somewhat enclosed area im working with a CCS company to reduce overall global GHG emission's and we're trying to come up with a machine that essentially uses CO2,CH4 and NO2 as fuel sources with no combustion however we've run into an issue of sorts as we've also decided to go into collecting noble gases as well and we'd like to increase the concentration of these gases however i have no idea as to how to accomplish this. I've looked everywhere on the web and i've ran into methane hydrates, Increasing gas pressure's and an overall lack of sources on the idea as i'm working with atmospheric conditions not aqueous. One solution to this could be building an aqueous permeable membrane but idk how that'd work with the other gases that are absorbed such as the noble gases. So i'd really like some help.
Some developing countries have plenty of biomass resources, but they couldn't exploit them effectively and efficiently yet due to several reasons --not only technological aspects but also economic aspects. Therefore, which factors do you think are crucial in sustainable utilization of biomass sources in the developing countries?
In many countries, energy based on renewable energy sources is being developed. This development is determined by many economic, ecological and geographical factors. This development results from the need to reduce greenhouse gas emissions and reduce the scale of air pollution by exhaust from mechanical vehicles. The development of energy based on renewable energy sources is indispensable due to the faster global warming process. Therefore, energy based on renewable energy sources should be developed.
Do you agree with me on the above matter?
In the context of the above issues, I am asking you the following question:
What are the main determinants of the development of renewable energy sources?
I invite you to the discussion
Thank you very much
For the classical power industry to be replaced with renewable energy sources, it is necessary to have the right policy at the state level but also at the supranational level.
The supranational organization of common markets on the example of the European Union is perfect for this issue. In the European Union, successive reforms are being undertaken to motivate the development of modern energy solutions and environmental protection.

In early 20 century most of the world major fisheries are depleted or decline, tropical forest are continues to shrink at 30 million acres per year, ground water withdrawals continues to deplete aquifers in all major water scarce region of the globe. Clearly, management of renewable resource remain a major concern.
Please can anyone explain how can I know the ability of renewable resources (solar and wind) to meet hydrogen demand at refueling stations?
any document, report, pdf, book, and articles or answers please share them with me.
thanks in advance
When the depletion of minerals, classic energy sources such as oil, hard coal and lignite, natural gas will generate market high increases in prices of these commodities on commodity exchanges?
In this question I point to economic issues and not speculative ones. Investment funds and large energy corporations are buying forward contracts for the supply of these raw materials.
The investment risk is high and the possibility of price forecasting is not easy considering the speculative transactions of investment funds and a number of non-economic factors, such as political factors in the production of crude oil.
However, in a few dozen years some of these minerals may start to run out. Until then, the economy should determine the creation of other energy technologies, ecological innovations in the field of energy and substitutable energy sources, mainly based on renewable energy concepts.
So when are the non-economic determinants influencing the energy prices on the wholesale exchanges, the commodities will be replaced and replaced by economic determinants?
When the scale of depletion of these minerals will affect the prices of these raw materials, it will increase the prices of these minerals and in this way will accelerate the process of creating eco-innovations and renewable energy?
In view of the above, I am asking you: When the depletion of minerals, classic energy sources such as oil, hard coal and lignite, natural gas will generate market high increases in prices of these commodities on commodity exchanges?

One of the great challenges is to find a sustainable way to obtain biobased products from renewable resources. A significant emphasis has been on the developmental biorefinery concept and maximizing the exploitation of biomass into value-added products for utilization in Metallurgical Industries.
I am looking for an example feed-in-tariff which is released by any goverment to encourage users for battery installation to consume self-generated electricity in smart homes.
Dear friends, colleagues, and professors,
I am interested in become familiar with electrification process in different countries. As I read, in some countries, such as Sweden, householders have this option to buy energy from different retailers and the maintenance/reinforcement of distribution network is done by distribution system operators. In this regards, how is distribution network loss allocated among consumers and/or retailers?
Thank you for sharing your experience from different regions of the globe.
Hello, I am looking at possible ways to store and use the surplus power generation from renewable energy plants, solar and wind farms above all. I would be willing to collect some data first, so it would be great if anyone had literature or information about how much surplus is generated. I know the topic is very broad but anything could help.
Thanks a lot.
Due to increasing population, there is a trend to move towards offshore wind energy harvesting for better energy management
According to Marek and Michael, the pyrogas of scrap tires comprises hydrogen, methane, ethane, butadiene, carbon monoxide, carbon dioxide, propane, propene, butane and other hydrocarbons.
(1)What are the average percentages of these compositions in the pyrogas?
(2)How can I calculate it's Gross Calorific Value (GCV) since its compositions vary according to pyrolysis processes (correct me if I'm wrong).
There is an issue in a region in the Philippines wherein an excess of renewable energy seems to be the problem. I would like to know how this is considered to be problematic when having an excess of renewable energy is not really 'wasteful' as it is renewable in the first place.
I am preparing a sustainability column for the Pastemagazine.com Science page focusing on wave energy as a renewable resource. I recently learned that NASA has developed a new technology that can boost the output of wave energy devices, but I need to understand how the energy from waves is captured now.
I'd apprentice any direction you can provide to (a) guide my research - published papers, current researchers, university programs in this area, and (b) find an expert willing to be interviewed about this subject.
And I'd like your thoughts on whether wave energy is an untapped resource - just a solar and wind once were.
Human urine is a nutrient rich renewable resource. There is prejudice of using urine and it gets lost down the drain and becomes the cause of concern for receiving environment. Presently a good number of studies has established potentials of bioregenerative reclamation of human urine in aquaculture and hydroponics practices. By this was we can kill the two birds with single stone! We can recover nutrient resources and use it in productive economic practices and avert the pollution.
Today marks the day in which the renewable resource of the planet have been exhausted, which creates a so-called Ecological Debt. I would like to know how statistics for this statement are compiled? How serious is this claim on scientific merit?
Options for development of RES are based on FIT or TGC models of energy generation payment ?
What is better solution for country/investor? Why?
I've been read some journals about microalgae biofuel. I think it seems to be feasible in engineering view because microalgae have high content of lipids and carbohydrate. Beside that, microalgae also have high growth rate. But, I doubt its feasibility in economic view because the first investment is very high. How do you think about this? Can you give the other sources of biofuel which more economic feasible than microalgae?
Management of a renewable natural resource such as stock of fish is key to sustainability of the resource. While simulating the population of a renewable resource such as fish stock, we expect the system (Stock & harvest) to converge to a steady state equilibrium (i.e. initial stock is in the basin of attraction). However, this is often not the case since there is a likelihood of experiencing a complex dynamic behavior including deterministic chaos where steady state equilibrium is never reached. Consequently, managing a fishery becomes a nightmare. What are some of the key determinants of such complex dynamic behaviors & how should a resource economist deal with such problems as far as managing a renewable natural resource is concerned?
How can one get the load demand data for importing the same in a HOMER software for renewable energy modeling?
Can we use random data or we have to monitor it for a year or else do we have to get it from any of the authorities?
I am trying to find out the degree days , heating degree days and the cooling degree days for Abu Dhabi. My question is how do I determine which base temperature value to choose for my calculations. I have come across different base temperature values for different regions. For Saudi Arabia I came across a base temperature value of 18.3, for Scotland the values were different for CDD and HDD values, any help in this regard would be helpful.
When applying the UKMO equations I am getting the negative values for the HDD (heating degree days), though when applying the Ashrae Formula we either get positive values or 0 (given that the condition remains unfulfilled). So I was wondering what is the significance of these negative values of Degree Days?
we have 14-bus IEEE, and replace one of the existing generators with a renewable generator (wind or solar). The power capacity of the renewable resource should be equivalent to that of the conventional generator
that it will replace
renewable data is of sufficiently high resolution, at least five-minute resolution.
In fact the question can be widened:
How is water flow measured, how is the head measured and how is the efficiency calculated, are there different methods for obtaining efficiency of different types of water turbines, or for different set of flow-head parameters?
A set of practical papers or standards may be suggested for practical use.
Should we ask running a model test before manufacturing or running efficiency test after commissioning or both.
We would like to verify the claimed efficiency . Thank you
Today I watched the video about 3D printing construction and I thought renewable/recycling materials could be adapted as a 3D printing material or used in other ways as a part of construction such as insulation or complex facade.
However, I assume there are some problems using renewable materials in 3D printing construction.
I hope to know any instances in terms of my assumptions.
In Spain the reguralization is not too equal than other countries. There are some taxes which are not correct. This is slowing the integration of the Renewable Energy Sources in the households. Although Spain has much renewable resources, the government keeps off the development of RES. The auto-consumption is now viable and it needs inversion to improve the technologies and the payback.
I am planning to prepare fact sheets and quizzes for secondary school and pre-university students in order to promote awareness of environment education in regard to climate and conservation.
According to the IEA Perspectives (or the EU SET Plan), the share of Renewables is expected to increase in the coming years. Biodiesel is a well-known technology and the production potential of installed plants is largely underexploited. So it seems reasonable to presume that Biodiesel production will still keep growing in the near future. However, competition for feedstock supply, development of new technologies (i.e. green diesel) and concerns about biodiesel degradability and long-term effects on engines have also to be taken into consideration.
So what will be the most probable development of biodiesel production in the next 10-20 years?Will it keep growing or will it be outcompeted by other Renewables?
Poly(3–hydroxybutyrate)–co–(3–hydroxyvalerate) (PHBV) is the only 100% biodegradable and biocompatible polyesters synthesized by bacterial fermentation from renewable resources. Cellulose nanocrystals only enhance the strength of PHBV, which restrict its application.
Can any part of lead furnace slag be reused? Can the heat it produces be converted to energy sources?
We have 40 to 50 years dedicated to research on renewable energies. I would say the first big impulse was the oil crisis of the early 70s. But previous research existed.
Many books and articles and other texts were produced in this period. Which would you say is your favorite?
The term 'renewable' is often used to indicate that a material (or a form of energy) originates from a non-fossil source (biomass for example). However to be 'renewed' the material must return to a form that can be considered as a feedstock again. To be 'recyclable' only implies that a material can be recycled, which may not actually be the case. Is it wrong to use this terminology in a 'cradle to gate' sense or is this a sensible approach because what happens after use cannot not be known before and during use?
Taking into account the limited land area, water resources, energy resources, economic aspects, and considering the threat of global warming and rising sea levels, small islands would face more difficulty in having a sustainable source of water. This research is an attempt to find a solution to make isolated areas self-sustaining in terms of their water and energy demands.
