DBH classes can be establushed and data can be classified via PCORD or R softwares.

Searching for a PhD/Research position in the field of “Energy Transition”

Dear connections, I’m currently searching for a PhD/Research position in the field of “Energy Transition”, with a strong interest in Energy Systems Analysis & Modeling as well as Clean Energy Technologies (EV,..). My research track is in the field of energy market analysis & forecast using AI. In my M.Sc. thesis at The American University in Cairo, I managed to build an energy planning model using different ANN topologies, that will help in securing the balance between the energy supply and demand in the United Kingdom for different end-use sectors; domestic, industrial, transport, and services sectors. I also carried out a long-term forecasting for the UK's final energy consumption up to the year 2035, and analyzed the results comparing to the outlook of the UK’s governmental department of Business, Energy & Industrial Strategy (BEIS). Being a Future Energy Leader at the World Energy Council and an energy transition advocate, I understand the importance of humanising energy and contributing to the global dialogue on energy and sustainability issues. On the other hand, I have 11 years of professional experience in the oil and gas, refining, and petrochemical industries at Enppi, one of the leading engineering and EPC main contractors in the Middle East and Africa. I am definitely open to expanding my career path in other "Energy Transition" fields of research, and open for relocation, if the PhD requires so. Please let me know if there are any potential openings. Thank you.

What, in your opinion, are the methods, ways, legal solutions, new material and other technologies to reduce paper consumption, save wood and trees?
What, in your opinion, are the actions and projects that can contribute to forest conservation, to convert deforestation into afforestation, to protect the climate, biosphere and biodiversity of the planet's natural ecosystems, to reduce greenhouse gas emissions and counteract the ongoing process of global warming?
As we know, trees, forests, especially old, natural forests, primeval forests with old-growth forests without human interference, without the influence of civilization, are the refuge of the greatest resources of biodiversity of natural ecosystems. Besides, forests play a particularly important role in the issue of slowing down the human-induced global warming process, which is progressing faster and faster. Forests also play a very important role in mitigating weather and climate anomalies, maintaining a mild microclimate friendly to living organisms, keeping the soil and air moist, maintaining the high level of biodiversity and soil fertility created over thousands or millions of years, and so on.
Deforestation still dominates over afforestation in many regions of the world. Forests are still being cut down and burned to acquire new areas for agricultural development, the cultivation of crops, which is usually carried out in the form of unsustainable robbery. In addition, this practice is carried out mainly in the tropics and subtropics, where after logging, forests created new arable land is quickly subject to drought and the soil becomes barren. Restoring a forest that has functioned for thousands of years or more in a specific area on the depleted soil requires huge expenditures. In addition, vegetable crops are grown on these new agricultural areas, which are either transported thousands of kilometers to other countries, which generates high greenhouse gas emissions, or are not used for human food but for livestock feed, which also generates high emissions, as industrial livestock farming is a source of high emissions of the potent greenhouse gas methane. Therefore, with a view to protecting the climate, biosphere and biodiversity of the planet's natural ecosystems, to reduce greenhouse gas emissions and counteract the ongoing process of global warming.
Various examples of reducing paper consumption and saving forests are as follows:
In some countries, the scale of printing notebooks, notebooks, books, including school books, has been reduced and students as early as elementary school write at school on tablets or laptops rather than in paper notebooks. Green economic activities involving, for example, the production of furniture from recycled materials are also emerging.
Another example is the replacement of dirty energy based on burning firewood with renewable and emission-free sources of clean energy. Unfortunately, in some countries, in order to falsify statistics on the development of renewable energy at the behest of the government, central statistical institutions, ministries and government agencies dealing with climate and environmental issues also count firewood as a renewable energy source. Such absurdities unfortunately still exist in some countries.
Another example is the use of secondary raw materials of various origins in the construction industry instead of using wood, and especially instead of newly harvested wood from companies producing building materials based on fresh, new wood raw material from a sawmill.
As of 1.8.2023, paper receipts are not printed in France to save trees. You have to ask for a printed receipt if the customer needs one.
What other examples of reducing paper consumption and saving forests are as follows?
In view of the above, I address the following question to the esteemed community of scientists and researchers:
What, in your opinion, are the actions and undertakings that can contribute to forest conservation, to convert deforestation into afforestation, to protect the climate, biosphere and biodiversity of the planet's natural ecosystems, to reduce greenhouse gas emissions and counteract the ongoing process of global warming?
What do you think are the methods, ways, legal solutions, new material technologies and others to reduce paper consumption, save wood and trees?
How can we reduce paper consumption, save wood, trees and reduce forest deforestation, protect biodiversity and climate?

Counting on your opinions, on getting to know your personal opinion, on a fair approach to the discussion of scientific issues, I deliberately used the phrase "in your opinion" in the question.
The above text is entirely my own work written by me on the basis of my research.
In writing this text I did not use other sources or automatic text generation systems.

Imagine the situation that a new different but much more perfect version of something similar to ChatGPT is built, for which each person can ask only one question, what would that question sound like?
In the current era of rapidly developing information technology, the technology of Industry 4. 0, the era of the fourth or perhaps already fifth technological revolution, in the situation of rapidly developing artificial intelligence technologies, building more and more perfect robots and androids, which, equipped with artificial intelligence, can perform a variety of activities until recently performed only by humans and until recently widely recognized as such, which only humans can perform, many new concepts are emerging, full of admiration for the modern technology of new applications of artificial intelligence, but also many new or well-known for many years but now growing in importance concerns about the development of artificial intelligence, including concerns about the consideration of the possibility in the future that the development of artificial intelligence will escape human control. In the context of, on the one hand, admiration and, on the other hand, concerns about the effects and directions of artificial intelligence development in the future, new intriguing questions are emerging. New questions, which, having the character of intriguing questions, activating creative reflection, motivating critical thinking, play a special role in the development of science. For example, this kind of question:
Imagine the situation that a new different but much more perfect version of something similar to ChatGPT is built, for which each person can ask only one question, what would this question be like?
Does this question have such a character, does it activate creative reflection, does it motivate critical thinking? I hope it does.
Please give an example of a question you would ask for a built new much more perfect version of something similar to ChatGPT, for which each person could ask only one question.
Please answer,
Thank you very much,
Best regards,
Dariusz Prokopowicz
