The energy companies are against carbon neutrality and fixing the problems they caused.

The issue with biofuel I can think of is it still produces waste gasses (but does reduce overall waste and might redirect some but landfill is normally compacted well to do that too - the waste normally isn't allowed to breathe for long).

I was looking into using renewables for crypto mining and it looks like they might pay higher than directly connecting them to the grid (for smaller sized operations) as the power companies normally only offer half the price of the electricity in return while it's generated (although that was taken from solar and I was looking into wind). That being said, at $400-2k a miner and $3-6k a wind turbine to power it there's probably a reason there aren't that many people doing it.
