Cryptominers defend gigawatt-scale energy usage called out by Congress

The Environmental Protection Agency and the Department of Energy are being urged by a group of Democrats to crack down on the industry.

The letter was signed by four senators and two representatives Cryptocurrencies are estimated to consume more energy than any other country, and environmentalists have long raised concerns about them.

Seven firms in the U.S. have built more than 1.045 gigawatts of capacity, according to the report. It's enough capacity to power all the homes in Houston. Stronghold, Greenidge, Bit Digital, Bitfury, Bitdeer, Marathon, and Riot are some of the mining farms highlighted in the report.

The industry is poised to grow rapidly and is likely to be problematic for energy and emissions. They don't know the full scope of the activity. They called for more data.

The companies downplayed the industry's contribution to planet- cooking emissions. They highlighted their individual efforts to curb emissions.

Marathon said it worked with energy companies to build clean, green, renewable energy resources that might not otherwise be built. The majority of Marathon's energy comes from a coal-burning plant.

Riot pointed out the use of hydroelectricity in upstate New York, as well as the fact thatBitcoin mining drives more demand for renewable energy than the typical US consumer of energy. Riot has seven times the capacity and draws power from the state grid. The state of Texas generated most of its energy from nonrenewable sources.

Stronghold is working to convert coal refuse into energy. It's a good idea to clean up coal mining waste. The harmful emissions from burning coal waste can be mitigated by the use of scrubbers.

Blockfusion and Bitdeer used software to reduce strain on energy grids.

The majority of emissions cuts in the US need to come from the power and transportation sectors. The White House said in April last year that it wanted to cut US greenhouse gas emissions in half.

Democratic lawmakers in D.C. have recently sought to curtail emissions via tax credits, which could juice both renewable energy generation and electric car sales The most certain path for the U.S. to follow is to pass clean-energy tax credits this summer, according to Energy Secretary Jen Granholm.
