Different energy sources refer to the numerous ways we harness and utilize energy. They comprise renewable and nonrenewable kinds of energy. The kind of energy we select is determined by several aspects, including how it affects the environment and whether it’s affordable and readily available.
In 2018, fossil fuels (oil natural gas, and coal) made up 81 percent of all the energy consumed in the world. These nonrenewable energy sources can be harmful to the environment in a variety of ways. For example, oil drilling can have a devastating effect on wildlife and communities. Fracking contributes to pollution of water. Coal power plants emit CO2.
Renewable energy, also called clean or green energy, comes from naturally occurring and continuously replenishing resources such as sunlight as well as wind and water. It’s an excellent way to decrease our dependence on fossil fuels and help the planet.
But renewable energy isn’t just about protecting the environment, it’s also about being reliable, efficient, and cost-effective. That’s why renewable energy is becoming more popular as a method to power our homes, businesses, and vehicles.
The most widely used renewable energy sources are wind, solar hydropower, nuclear. Solar energy uses technology to convert sunlight into heat and electricity. Wind energy captures the kinetic energy generated by moving air to create electricity and is used in many locations across the globe. Hydropower harnesses the force of rapidly moving water to create electricity. Nuclear energy generates electricity using the atomic fission process.
