Renewable energy technologies harness natural resources to generate power without depleting them. Common sources include solar energy, which captures sunlight using solar panels, and wind energy, which uses wind turbines to convert wind movement into electricity. These technologies help reduce greenhouse gas emissions and combat climate change. Another important renewable source is hydropower, which generates energy from flowing water, typically through dams. Additionally, biomass energy utilizes organic materials, like plant waste, to produce heat and electricity. By investing in these technologies, we can create a sustainable energy future that benefits both the environment and society.
