People who don't know grids or Bitcoin say:
"Bitcoin is waste by design"
Renewable operators say:
"Bitcoin prevents waste by design"
Here's how: ever heard of a Load Bank?
It's probably the only piece of hardware in the world that was designed to waste electricity.
Why?
Sometimes, renewable generators get asked to curtail energy suddenly.
Powering down can create a lot of wear and tear however, so many renewable operators prefer to send some of that power to a load bank, which does nothing other than chew up surplus electricity.
A 500kW Loadbank will set you back $28,490 and is a far more challenging e-waste conundrum than any Bitcoin miner.

When renewable operators replace their loadbanks with even some old Bitcoin miners, they not only help secure a sound-money network, they earn Bitcoin.
Bitcoin Mining is the cure for waste-by-design, by obsoleting the need for Load Banks, and helping renewable operators become more profitable, so they can expand their operations.
