Different energy sources refers back to the different ways we harness and use energy. They include renewable and nonrenewable forms of energy. The kind of energy we choose is determined by a number factors, such as how it impacts the environment, and if it’s affordable and accessible.

In 2018 fossil fuels (oil natural gas, and coal) made up 81 percent of all the energy used in the world. These nonrenewable energy sources could be harmful to the environment in many ways. For example oil drilling could cause devastating harm to wildlife and communities. Fracking contributes to water pollution. And coal power plants emit CO2.

Renewable energy is also known as green or clean power. It is derived from resources that are constantly replenished, like sun, wind, and rain. It’s a great choice to reduce our dependence on dirty energy sources and helping the planet.

But renewable energy isn’t only about protecting the environment; it’s also about being reliable and cost-effective. Renewable energy is becoming increasingly widely used to power our homes and businesses.

Solar wind, nuclear and hydropower are the most popular renewable energy sources. Solar energy is a technology that converts sunlight into electricity and warmth. Wind energy captures the kinetic energy of moving air to generate electricity and is used in many locations all over the world. Hydropower harnesses water’s force to generate electricity. And nuclear energy uses the process of atomic fission to make electricity.
