Climate change is causing more heat waves and droughts in Europe, which can lead to water shortages. The lack of water may affect power plants from having enough water to cool down, making it harder to generate electricity. Scientists looked at how this could impact Europe's power supply. They found that as climate change makes droughts and heat waves more common, there is a risk of power shortages due to water scarcity for cooling power plants. This study shows that climate change isn't just about the weather; it can also affect how we get electricity.
