The significance of using renewable energy sources in combating climate change lies in their potential to reduce greenhouse gas emissions and promote sustainability. Unlike fossil fuels, renewable energy sources like solar, wind, and hydroelectric power generate electricity without emitting harmful pollutants. Transitioning to renewables can decrease dependency on non-renewable resources, enhance energy security, and create economic opportunities. Investing in renewable technologies also aligns with efforts to mitigate climate change impacts, fostering a transition toward a low-carbon economy and helping to stabilize global temperatures.
