> We MUST MUST stop burning things.
Yes, we must. It is so rare to see someone saying this in public. Thank you for this simple clarity.
Stop burning everything! Fossil fuel, wood, plastic, garbage, paper. Stop making methane.
We only need solar energy at 1 dollarcent or eurocent (it will get much cheaper still!!) and a little batteries for the convenience of using electricity when the sun does not shine.
In the north and south you need more solar panels in the winter than in the summer by a factor of 50. But that pays it back in summer when you have a squanderable abundance of free and clean energy. We can store that surplus energy in purifying drinking water, melting iron ore or aluminum [5], melting reusable plastics or purifying silicon ingots.
Storing surplus heat or cold in the ground is another luxury, because it is more expensive than 1 dollarcent or eurocent solar running a heatpump.
Wind and hydro are also more costly than solar so they are another luxury with worse environmental costs than pure solar cells.
We need to build Enernet, a peer to peer electricity net and internet between all buildings with power routers. for around 100 dollar per building. You buy and sell your house surplus solar electricity to the neighborhood where it can be stored in car batteries. See my Fiberhood white paper [2].

I don't understand the wood argument. Isn't it widely accepted we need to do burns to manage forests? Wood is a short-term cycle of carbon. It releases when it burns but frees up space to capture it right after. When people live on rural plots and trees fall, should they burn for heat (and lessen needing other energy sources) or let it decompose and cause the same thing? It's not the same as extracting deeply embedded carbon sources that won't make it to the atmosphere if untouched (fossil fuels)
Wood and plant burning requires a longer nuanced answer than the Hacker News format allows. Humanity must not cut forests or grow plants unnecessarily. If you must use wood to build a house -(there are better and cheaper materials in terms of energy and climate change enhancing emissions, see for examples Amory Lovins book Reinventing Fire or his lectures on Youtube) - then first grow those trees in a place that has no natural forest. And then do not burn the wood after you demolish the house. Do not use wood from forest, humans should let the forest manage itself.
Same with clearing the underbush of Meditaranian and hotter climate forest to prevent forest fires. If humanity had not managed those forest (grazing animals, building roads, harvesting) in the first place than there would have been no buildup of excess material that sustain wildfires past its natural rate.
The trick to forest management is allow or create small, frequent burns that clean up dry, overgrown understories. Nature does this without our help and some species even depend on it. If we interfere with this, eventually there's a big fire instead that levels the place.
