'Factor 3' Solution: the heat pump

Electrically-driven heat pumps for heating buildings typically supply 100 kWh of heat with just 20-40 kWh of electricity. Heating buildings causes 30% of global CO2 emissions. More wide-scale use of heat pumps could save 1200 million tonne of CO2 emissions annually, i.e. about 6% of global emissions, or 30% of the EU's emissions. According to an UIE report on electric technologies, it is one of the largest savings that a single technology can offer.
