Why electrification is the climate game changer we need
4 日前
Electrification isn't just a buzzword, it's a lever that could slash energy bills while reducing the world's dependency on coal, oil and gas. Which also means significantly slashing the heat-trapping CO2 emissions that are linked to flooding and extreme heat around the world.
If fuel-importing countries "speed up the electrification of their economies considerably" they could knock more than $400 billion (€357 billion) off their energy import bills by 2035 compared with 2025 levels.
That is according to a recent analysis by the International Energy Agency , which also found that such an acceleration could mean the world needs 18 million fewer barrels of oil per day.
In a nutshell, electrification means replacing technologies that burn fossil fuels such as oil and gas with electric alternatives. That means switching from diesel cars to electric vehicles (EVs), turning off gas heating and using electricity to power heat pumps .
But the way the electricity running these things is generated is also important. In theory, an EV using power created in a coal-heavy electricity grid could be worse for the climate than a car running on gas.
Electricity derived from renewable energy sources such as solar , wind or hydropower on the other hand produces clean power.
