Renewable energy technology refers to methods and systems that harness energy from natural resources that are replenished over time. This includes sources like solar energy, wind energy, hydropower, and biomass. These technologies aim to reduce reliance on fossil fuels, which contribute to environmental pollution and climate change. The main types of renewable energy technologies include solar panels that convert sunlight into electricity, wind turbines that capture wind energy, and hydroelectric plants that generate power from flowing water. By utilizing these sustainable resources, renewable energy technology promotes cleaner energy production and helps combat global warming.
