What's 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.
In most models that show the world reducing emissions enough to hit the 2 °C climate target, «solar energy emerges only as a minor mitigation option» — around 5 to 17 percent of
global electricity supply in one representative study used by the Intergovernmental Panel on Climate Change (IPCC).
If we had tried to accelerate decarbonization by deploying 1980s solar technology, it would have cost a staggering $ 53.5 trillion to scale up solar to provide just 11 percent of
total global electricity supply, according to WRI's numbers.
According to long term scenarios, hydropower's share in
global electricity supply may decrease to 10 to 14 percent.
According to the Australian - based think tank Long Future Foundation, if bitcoin price goes up and reaches $ 1 million, bitcoin mining would consume 60 % of
global electricity supply.
