Det er en ret lille andel el der bliver produceret af kul og andelen bliver mindre og mindre. Men du har ret i at det er spild af energi.
A report published Friday by the International Energy Agency found that global demand for electricity surged 6% in 2021, fueled by a colder winter and the dramatic economic rebound from the pandemic. That drove both prices and carbon emissions to new records.
The growth in demand was particularly intense in China, where it jumped by about 10%.
IEA Executive Director Fatih Birol said the report contained a stark warning for the future.
Electricity has a crucial role to play in the fight against climate change as countries ditch fossil fuels and more battery-powered cars hit the road. But so far, renewable sources of electricity — as opposed to power stations that burn coal or natural gas — haven't kept up.
Electricity generated by renewables grew by 6% globally last year, while coal-fired generation leaped 9% due to high demand and skyrocketing natural gas prices, which made it look like a more attractive option.
Carbon dioxide emissions from power generation rose 7% as a result, reaching an all-time high after declining the previous two years.
