Trang 31 The Rise of Renewable Energy
1
In an era of increasing environmental awareness, renewable energy sources such as solar, wind, and hydropower are gaining prominence Unlike fossil fuels, these sources produce little to
no greenhouse gas emissions, making them vital for combating climate change Governments worldwide are investing heavily in renewable energy infrastructure to reduce reliance on non-renewable resources
