He said that bitcoin mining will save the world because the next generation of BITCOIN MINERS has started to work with energy that does NOT require Carbon Hydroelectricity and nuclear power wind and Solar .

The most importance findings of research was that the expansion of wind and solar power comes with life cycle emissions that are much smaller than the remaining emission from existing fossil power plants before they can finally be decommissioned.

critics sometimes argues that the nuclear  ,wind or solar power have a hidden carbon footprints ,due to their manufacturer and construction. This is a large carbon dept and the related energy must be paid off if they are to cut emission over a their life time.

Factories churning out solar panels use large amount of electricity often source from coal fire power stations in China .wind turbines and nuclear plants needs a lot of steel and concrete, And the centrifuges that separate nuclear fuel also rank up a big electricity bill.

Yet zero _ carbon source of electricity are not the ones to have a hidden ,indirect carbon and energy footprint.

For coal and gas ,these lifecycle energy uses and emissions comes from extraction machinery and fuel transport. Significantly ,they also from methane leaks at pipelines ,well heads or coal mines .these lifecycle emissions continues ,even if coal or gas plants add CCS ,which Which also may not captures 100% of emissions at the power plant .

Whets more ,the indirect energy uses and emissions of each technology will  shift over time, due to changing fuel sources ,advances in manufacturing and the evolution of global electricity supplies.
