economic reasons in protecting their vested interests." Some critics blamed the European Union Emissions Trading System (EU ETS) and closure of nuclear plants for contributing to the energy crisis. European Commission President Ursula von der Leyen said that Europe is "too reliant" on natural gas and too dependent on natural gas imports. According to Von der Leyen, "The answer has to do with diversifying our suppliers ... and, crucially, with speeding up the transition to clean energy." Health and environmental impact Moving to modern renewable energy has very large health benefits due to reducing air pollution from fossil fuels. Renewable sources other than biomass such as wind power, photovoltaics, and hydroelectricity have the advantage of being able to conserve water, lower pollution and reduce emissions. Solar panels change the albedo of the surface, so if used on a very large scale (such as covering 20% of the Sahara Desert), could change global weather patterns. Conservation areas, recycling and rare-earth elements Installations used to produce wind, solar and hydropower are an increasing threat to key conservation areas, with facilities built in areas set aside for nature conservation and other environmentally sensitive areas. They are often much larger than fossil fuel power plants, needing areas of land up to 10 times greater than coal or gas to produce equivalent energy amounts. More than 2000 renewable energy facilities are built, and more are under construction, in areas of environmental importance and threaten the habitats of plant and animal species across the globe. The authors' team emphasized that their work should not be interpreted as anti-renewables because renewable energy is crucial for reducing carbon emissions. The key is ensuring that renewable energy facilities are built in places where they do not damage biodiversity. The transition to renewable energy depends on non-renewable resources, such as mined metals. Manufacturing of photovoltaic panels, wind turbines and batteries requires significant amounts of rare-earth elements which has significant social and environmental impact if mined in forests and protected areas. Due to co-occurrence of rare-earth and radioactive elements (thorium, uranium and radium), rare-earth mining results in production of low-level radioactive waste. In 2020 scientists published a world map of areas that contain renewable energy materials as well as estimations of their overlaps with "Key Biodiversity Areas", "Remaining Wilderness" and "Protected Areas". The authors assessed that careful strategic planning is needed. Solar panels are recycled to reduce electronic waste and create
