Different energy sources refer to the various ways we can harness and use energy. They comprise renewable and nonrenewable kinds of energy. The type of energy source we choose to use depends on a variety of factors, including how it affects the environment as well as how accessible and affordable it is.

In 2018 fossil fuels (oil natural gas, natural gas and coal) comprised 81 % of the energy that was produced around the globe. These nonrenewable energy sources could harm the environment in many ways. For instance the drilling of oil can be devastating to wildlife and communities. Fracking causes pollution of water. Power plants that use coal index emit CO2.

Renewable energy, also called green or clean energy, is derived from natural and constantly replenishing resources such as sunlight or wind, as well as water. It’s a great option for reducing our dependence on fossil fuels and also helping the environment.

Renewable energy is not only about preserving the environment. It’s also about being affordable, reliable and efficient. That’s why renewable energy is becoming increasingly popular as a means to power our homes as well as businesses and vehicles.

Solar, wind, nuclear, and hydropower are the most commonly used renewable energy sources. Solar energy utilizes technology to convert sunlight into heat and electricity. Wind energy captures the kinetic energy generated by moving air to generate electricity and is used in many places across the globe. Hydropower harnesses the force of swiftly moving water to generate electricity. Nuclear energy produces electricity by using the process of atomic fission.
