Understanding Renewable Energy

What is Renewable Energy?

Renewable energy comes from natural sources that are constantly replenished, such as sunlight, wind, water, and geothermal heat. Unlike fossil fuels, renewable energy sources produce little to no greenhouse gas emissions, making them environmentally friendly and sustainable.

Types of Renewable Energy

  1. Solar Energy: Harnesses energy from the sun using photovoltaic (PV) panels or solar thermal systems.
  2. Wind Energy: Uses wind turbines to convert wind power into electricity.
  3. Hydropower: Generates electricity by capturing the energy of flowing water.
  4. Geothermal Energy: Utilizes heat from the Earth’s core to generate electricity or provide direct heating.
  5. Biomass Energy: Produces energy from organic materials like plant and animal waste.
