Structure of the articleEdit

In tidying up the article, I've changed quite a lot of the structure. There are a few things I'd like more input on:

a) Do we want to integrate environmental impact with the description of mainstream techniques? Tentative yes, as we'd otherwise introduce a third section with a subdivision per technique

b) Do we want to include a section/sections with information on efficiency, electrification and grid stability and storage? All three concepts are quite tightly linked to renewables, and the article should give a short introduction explaining that link. I'm not entirely sure how to best do this.

c) Developing countries is out of place, but I think it would also be out of place in a separate section or under policy. Maybe policy can be renamed into something else? Femke Nijsse (talk) 18:33, 17 April 2019 (UTC)

I suggest a section on the economics of renewable energy is added (but I am not going to write it myself). In particular the economics of variable (e.g. solar) and dispatchable (e.g. dammed hydro). Chidgk1 (talk) 16:15, 21 April 2019 (UTC)

Do you think economics should be a different section than market and industry trends. Or should market and industry trends be encompassed in the new economics section? Femke Nijsse (talk) 17:45, 21 April 2019 (UTC)
My 2 cents is definitely Yes for question A. We should strive to present a neutral point of view on every source of energy. I mentioned some of the serious issues with bioenergy in our Sustainable energy article. (In the longer term, we might want to look into ways to reuse content between the Renewable energy and Sustainable energy articles, but right now I'm just trying to make the latter into something halfway readable.)

Cool, I'll integrate the last section into the bio-energy section then.
OOh deary me, we have to articles for these very closely related articles. We should either merge explaining the differences in the lede, or very clearly pinpoint at the top of the page.. Femke Nijsse (talk) 06:52, 4 June 2019 (UTC)
We also have Alternative energy ;) Our sustainable energy article should obviously describe renewables, but it also has to talk about nuclear power, energy conservation, clean cookstoves, and perhaps even carbon capture and storage. So Sustainable energy should ultimately incorporate a summary of the Renewable energy article with about a quarter to a half as much detail. Clayoquot (talk | contribs) 16:09, 4 June 2019 (UTC)

Semi-protected edit request on 15 May 2019Edit

There have been new developments by an IEEE Technical Committee that show the impact renewables can have on the control and stability of electrical systems. This work has received the IEEE PES Best Technical Report in 2018. I suggest the following modification to the Debate section, at the end of the first paragraph:

Distributed renewable energy resources have been shown to have the ability to destabilise the bulk transmission system when proper control design is not considered. Their impact on the bulk transmission network and strategies to mitigate the negative effects have been analysed in [1]. Apetros85 (talk) 08:28, 15 May 2019 (UTC)

Thanks for your contribution. I'm not inserting it yet, because we're restructuring the article in such a way that net stability will get its own subsection (under Integration into the energy system) instead of being part of debate. I'll probably cite this research as well in that section, next to other important reports and articles on the topic. I'm currently busy with other articles, so if other editors would like to write it, be my guest. Femke Nijsse (talk) 08:44, 15 May 2019 (UTC)

Renewable energy is a misnomer as far as physics (thermodynamics) is concerned; this should be clarified in the articleEdit

As $title says. There is no such thing as renewable energy in physics, since expending energy, according to thermodynamics, is equivalent to expending entropy. Energy is required to be injected into a system in order to reduce its entropy, thus making this system a reliable source of energy again. — Preceding unsigned comment added by 78.123.99.88 (talk) 11:17, 12 March 2020 (UTC)

Renewable energy is the term used for the energy obtained by renewable sources like solar, wind, hydro, geothermal, nuclear, ocean and hydrogen etc. On the other hand we have coal, oil, gas etc which are depleting when used so they give non-renewable energy. Over a very long period of time (many millions of years) there is a progressive increase in entropy and a net loss of energy from the Earth to the rest of the universe but this natural process is not significant on time scales relevant to humans. The relation of energy and entropy is same for both of them and the energy is neither renewable nor sustainable.[1]
