> 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].
