A ‘paradox’: Is climate change the biggest threat to renewable energy?

🗞️ Driving the news: As Europe accelerates its transition away from fossil fuels amid the conflict involving Iran and disruptions around the Strait of Hormuz, a growing question is emerging: can renewable energy systems withstand the worsening impacts of climate change themselves?

🔭 The context: Renewables are expanding rapidly across Europe, with surging demand for technologies such as electric vehicles, heat pumps and rooftop solar
• But the same climate disruptions they aim to mitigate, heatwaves, stronger storms and changing rainfall patterns, are increasingly affecting how renewable systems operate
• For example, solar panels become less efficient in extreme heat, while wind turbines must shut down in very strong winds to prevent damage
• Hydropower is also becoming less predictable as warming temperatures reduce snowpack in countries like Norway, often described as Europe’s “largest battery”

🌍 Why it matters: The energy transition is not just about installing more renewable capacity
• It also requires resilient infrastructure, stronger electricity grids and improved forecasting systems to manage climate volatility
• Across the European Union, grid constraints are already delaying major renewable projects and limiting the ability to move electricity across regions when weather conditions change

💬 One quote: “While renewable energy sources are central to reducing emissions, they’re inherently dependent on environmental conditions.” — Thomas Balogun, renewable energy investor

📈 One stat: Solar panel efficiency typically drops by about 0.4–0.5% for every degree above 25°C, meaning extreme heatwaves can significantly reduce output during peak demand
