While solar and wind renewable projects appear to receive the lion's share of attention, geothermal power plays an important role as part of the toolkit towards tackling climate change. Some promising global developments are highlighted.
Geothermal energy is heat originating from below the earth's crust. Water and/or steam transport this energy to the Earth’s surface. Geothermal energy can be used for heating and cooling purposes or can be used to power turbines to generate renewable electricity. However, electricity generation requires relatively intense heat sources, which are usually located close to tectonically active regions.
In 2018, geothermal electricity generation accounted for just under 90 TWh world-wide. At the end of 2019, geothermal installations accounted for 0.5% of worldwide installed ren...
