Here is another renewable energy we little hear about… According to a new publication from the IEA, geothermal could provide about 3.5% of annual global electricity production, 3.9% of energy for heat by 2050.
As the press release notes : ” there is potential to achieve at least a tenfold increase in the global production of heat and electricity from geothermal energy – heat emitted from within the earth’s crust – between now and 2050. “
Currently, geothermal represents 0.3% and 0.2% of electricity and heat, respectively. It is worth noting that Indonesia believes this could bring up to a third of its electricity by 2025.
