More people than ever are currently looking for a clean, renewable energy source to meet their energy needs. Just because fossil fuels have been the norm doesn’t mean we shouldn’t consider change. Adopting new energy conventions leads to a healthier and happier planet. Keep reading to learn more about the seven types of renewable energy sources and how they can replace nonrenewable sources.
Bioenergy
Derived from biomass, this energy source creates heat, electricity, and liquid fuel. Generated from the organic matter of recently departed plants and animals, bioenergy is a cleaner solution to fossil fuels. Although both create a similar amount of carbon dioxide, bioenergy allows plants to continue to grow. This removes the carbon dioxide that was created from the atmosphere thanks to photosynthesis.
Ocean Energies
The ocean is a double hitter when it comes to renewable energy—it produces both thermal energy (with heat absorbed by the sun) and mechanical energy (by the motion of the waves). Both sources can be used to cut electricity costs and are easily accessible due to the fact that our planet is 70% ocean.
Geothermal
A result of the Earth’s heat, this energy source can be contained close to the surface with ease. Thanks to elements like heated rocks and reservoirs, a geothermal heat pump system can tap into these resources, harness the energy, and generate electricity from it.
Hydroelectricity
Hydroelectric energy most commonly comes from a dam system. When the water stored in a reservoir is released, it rushes through turbines and produces electricity. Outside of dams, hydroelectricity is also generated through run-of-river hydropower (ROR), which does not require a dam set up.
Wind Power
Chances are, you’ve seen windmills at some point in your life. Windmills capture the wind flow and transform it into electricity. This form of renewable energy has been utilized for centuries and is a reliable source.
Hydrogen Fuel Cells
There’s also an abundance of hydrogen on Earth. Found in organic compounds such as methanol, propane, and eater, this renewable source is high in energy produces little pollution during the harnessing process. Fuel cells can be used in a variety of devices, from cars to commercial power plants.
Solar Energy
Solar energy is captured by solar collectors (aka panels) and is then converted into heat and electricity. As it has become more affordable and easier to install, this form of renewable energy is gaining popularity.
The benefits of utilizing renewable energy are gaining more recognition each day. It’s cost efficient, creates more jobs, and—best of all—it’s good for the planet. With all the different types of renewable energy sources, it’s no surprise that the clean energy revolution is gaining more attention with each passing year.
