Renewable energy

What is Renewable Energy?

Renewable energy is generally defined as energy that comes from resources that are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat.

Renewable energy sources

Hydroelectric

Flowing water creates energy that can be captured and turned into electricity. This is called hydroelectric power or hydro-power.

Wind

Wind energy is the kinetic energy of the wind around the earth. This is an indirect kind of solar energy: solar radiation absorbed into the atmosphere causes differences in temperature and pressure. As a result, the air masses move and accumulate kinetic energy.

Solar

Solar power is energy from the sun that is converted into thermal or electrical energy. Solar energy is the cleanest and most abundant renewable energy source available.

Biomass

Biomass is biological material derived from living, or recently living, organisms. It most often refers to plants or plant-based materials but animal waste can also be considered biomass.

Geothermal

Thermal energy means “heat energy”. Geothermal energy is the heat energy of the Earth’s crust. It comes from the original formation of the planet and from radioactive decomposition of materials.

Biogas

Biogas belongs to the category of bio-fuels and is a renewable source of energy. Biogas is produced from the breakdown of biological material in the absence of oxygen (the lack of oxygen is called anaerobic condition).
