Europe's Wind and Solar Push Falls Short as Energy Bills Stay High
Many European countries that invested heavily in wind and solar power are still facing high energy bills despite cheaper renewable energy costs. The problem is that wind and solar need expensive backup power when the wind stops blowing or the sun isn't shining.
European countries poured money into wind and solar power to avoid getting hit by gas price spikes from wars and supply disruptions. The logic seemed sound: renewable energy costs less to run than fossil fuels once it's built.
But many countries are finding their energy bills haven't dropped as expected. The main problem is that solar panels don't work at night and wind turbines stop when there's no breeze. Countries need backup power during these gaps, which often means keeping expensive gas plants running.
Spain shows how to do it right. Since 2019, the country doubled its wind and solar capacity, adding over 40 gigawatts of clean energy - more than any other EU country except Germany. Spain's massive renewable build-out is keeping energy bills low even as gas prices soar.
The storage problem is huge. To keep the lights on during a typical week without wind or sun, countries would need about 85 terawatt-hours of battery storage - technology that's still very expensive.
Some countries also face a waste problem. When they produce too much renewable energy, the electrical grid sometimes refuses to take it at any price. This discourages companies from building more wind and solar farms.
This affects your electricity bill and shows why the switch to clean energy is more complicated than expected. Countries that got this right, like Spain, are keeping energy costs low while others struggle with expensive backup systems.
Watch how countries balance renewable energy with reliable backup power as gas prices stay volatile.
