There are several different types of renewable energy sources that can create electricity. Among the most common are solar and wind energy, but there are also biomass, geothermal, and hydropower sources.
The main factor that sets green power sources apart is that they do not release harmful chemicals – often called greenhouse gases – into the atmosphere. Fossil fuels such as coal and oil are responsible for most greenhouse gas emissions, including carbon dioxide.
Gases such as carbon dioxide make their way into the atmosphere and break down the ozone layer, which is a protective layer separating the Earth’s surface from ultraviolet (UV) radiation produced by the Sun. These levels of powerful radiation can cause skin cancer, harm the human immune system, cause significant damage to ecosystems, and endanger plant and animal species.
Green energy sources avoid these harmful effects. What’s more, most green energy sources are renewable, meaning it is more sustainable in the long run to use them as power sources over a finite amount of fossil fuels.
While all power sources are responsible for some environmental impact, choosing a green energy plan or opting to install your own solar panels can help you lower your home’s overall carbon footprint and better the environment.
