Types of Renewable Energy Sources
- Solar Energy: Solar power is harnessed through photovoltaic panels or solar thermal systems, converting sunlight into electricity or heat. It is one of the most widely used and accessible forms of renewable energy.
- Wind Energy: Wind turbines capture the kinetic energy of wind and convert it into electricity. Wind farms, both onshore and offshore, are becoming increasingly prevalent.
- Hydropower: Utilizing the flow of water, hydropower generates electricity through dams and turbines. It is one of the oldest and most reliable renewable energy sources.
- Biomass Energy: Biomass energy is produced from organic materials such as wood, agricultural residues, and animal waste. It can be used for heating, electricity generation, and as biofuel.
- Geothermal Energy: This energy is extracted from the heat stored beneath the Earth’s surface and is used for electricity generation and direct heating.
