Renewable energy sources are energy sources that are naturally replenished and have minimal impact on the environment compared to traditional fossil fuels.

They are considered sustainable because they are continuously available and can be utilized without depleting natural resources.

Renewable energy plays a crucial role in combating climate change and reducing greenhouse gas emissions.

Here are some common renewable energy sources:

Solar energy:

Solar energy is harnessed from the sun's rays using solar panels or photovoltaic solar cells (PV). It can be converted into electricity or used to heat water and spaces in residential, commercial and industrial applications.

Wind energy:

Wind energy is generated by utilizing the kinetic energy of the wind with wind turbines. Wind farms capture the energy of the wind and convert it into electricity.

Hydropower:

Hydropower is obtained from the energy of moving water, such as rivers or waterfalls. Dams or water turbines are used to convert the kinetic energy of the water into electricity.

Biomass energy:

Biomass energy is produced from organic materials, such as wood, agricultural residues and organic waste. It can be burned to produce heat or electricity or converted into biofuels.

Geothermal energy:

Geothermal energy is obtained from the heat in the Earth's crust. It is harnessed by tapping natural geothermal reservoirs to produce electricity or for direct heating and cooling applications.

Tidal energy:

Tidal energy is generated by utilizing the kinetic energy of tidal movements in the ocean. Tidal turbines or weirs are used to convert the energy of the tides into electricity.

Wave energy:

Wave energy is produced by capturing the kinetic energy of ocean waves using wave energy converters. It can be converted into electricity.

Benefits of renewable energy sources:

Renewable and sustainable: They are constantly replenished by natural processes.
Environmentally friendly: They produce little to no greenhouse gas emissions and have minimal impact on ecosystems.
Energy security: they reduce dependence on fossil fuels and ensure a diversified energy mix.
Lower operating costs: Over time, renewable energy systems can lead to cost savings compared to traditional fossil fuels.
