Renewable energy sources


Renewable energy sources, commonly referred to as renewables, encompass energy derived from naturally occurring and replenishable sources. These sources are characterized by their sustainability, as they can naturally renew themselves on a human timescale. Unlike finite fossil fuels, renewable energy sources contribute to a more sustainable energy landscape due to their ability to be continually replenished. Renewables include various forms such as solar energy, wind power, hydropower, biomass, and geothermal energy.

  1. Solar Energy: derived from the sun’s radiation, solar energy can be harnessed using photovoltaic cells to generate electricity or through solar thermal systems for heating applications.
  2. Wind Energy: generated by harnessing the kinetic energy of the wind using wind turbines to produce electricity.
  3. Hydropower Energy: generated from the energy of moving water, typically through the use of dams or water turbines.
  4. Biomass Energy: derived from organic materials such as plants, agricultural residues, and organic waste, which can be burned or converted into biofuels for energy production.
  5. Geothermal Energy: harnessed from the heat beneath the Earth’s surface, often used for electricity generation or direct heating applications.
