"with wind the single-biggest contributor.... Power production costs have declined “by almost half” .... And the clean energy sector has created 50,000 new jobs.... Ask me what was the impact on the electricity sector in Uruguay after this tragic war in Europe — zero."

We really need to think of biomass as batteries. In both cases, it’s tough to scale up enough for full coverage but we know how to store biodiesel or ethanol, it’s very energy dense. Scattering a bunch of diesel generators with big biodiesel tanks might be a better answer than batteries for when the wind doesn’t blow

It also ensures a market and distribution industry for farming and construction vehicles where batteries may not work

    It takes a decade and quite a bit of space to make a tree (for example), it's technically renewable but the fuel production is very slow. I'm curious how they're planning to keep that up

    Other things grow faster and take up less space than trees. For example most biofuel is made from maize and sugarcane.

    Also how is biomass a battery? You can't put energy back into a forest

    By that logic you could also not call the flat thing inside a phone a battery because it can't feed back into the grid.

    Other way round, you can take biomass and turn it into electricity easily. But you cant easily turn electricity into biomass. (it is easy on a phone to go both ways tho, google "USB c OTG adapter")
