Renewable technologies refer to methods and systems that harness energy from natural resources that are replenished over time. These include sources like solar energy, wind energy, hydropower, and biomass. Unlike fossil fuels, which can deplete and contribute to environmental issues, renewable technologies aim to provide sustainable energy solutions that reduce greenhouse gas emissions. These technologies often involve the use of specialized equipment, such as solar panels for capturing sunlight or wind turbines for converting wind into electricity. By utilizing these resources, renewable technologies help to create a cleaner and more sustainable energy future, benefiting both the environment and society.
