which is simply mining Bitcoin and cryptocurrency using renewable energy sources such as wind, solar energy, and hydroelectric power.

Bitcoin is infamous for wasting enough electricity to add 40 million tons of carbon dioxide to the atmosphere a year—but now, a growing cadre of U.S. miners are developing green, lucrative, new strategies worth a fortune all their own.

Complex algorithms must be solved to validate and record Bitcoin transactions on the blockchain. This is all part of Bitcoin's proof of work consensus mechanism, which aims to add a new block every 10 minutes. The more processing power a miner has, the more likely it is to win a block.
