While the world brings record levels of clean energy online, geothermal energy growth is virtually stagnant, but the increased push to decarbonise heating systems could see the technology receiving renewed attention.
Heating and cooling
The International Energy Agency's net-zero emissions pathway urges policymakers to begin banning the sale of new fossil fuel boilers and furnaces in 2025. Governments should not wait that long.
With more than 100 of the world's largest businesses committed to entirely electric fleets by 2030, there will soon be millions more electric vehicles on the road, requiring huge investment in charging infrastructure. How might digital technologies help ease the transition to electromobility?

Energy experts that advocate heating homes with hydrogen rather than turning to deep renovation and building insulation as their first port of call will make the energy transition more expensive for everyone, says Jan Rosenow from the Regulatory Assistance Project.
Road transport and buildings have been spared from EU ETS obligations until now, but an upcoming revision may change that, and climate campaigners are concerned.
China and other Asian countries will have to be much more ambitious if the world is to achieve CO2 emissions cuts from buildings in line with global climate goals.
The UK has made strong commitments to build back better from Covid-19, but recent hiccups raise questions over whether it can deliver on its pledges.
In the wake of Texas’s crippling power outages, policymakers should focus on building a more resilient, interconnected and diverse power grid.
Heating homes with excess heat from power plants instead of individual boilers seems like a climate no-brainer, but given its historical reliance on coal, does the technology have a place in the clean energy transition?
As energy systems electrify, it will become increasingly important to measure renewables as a portion of power generation to understand how fast economies are decarbonising.
Heat pumps provide energy-efficient heating and cooling and are one of the most effective technologies available to decarbonise buildings.
