Almost a quarter of energy generation around the world comes from renewable sources. As people realize the benefits of going green, they’re looking to renewable energy as one way to be more eco-friendly.
As a result, renewable energy is a growing industry. Green energy comes in several different forms though. Some are more accessible than others.
Here are the five most common types of renewable energy you’ll hear about.
Most renewable energy today comes from hydroelectric generation. This harvests the power of moving water, which turns turbines to make electricity.
Hydroelectricity is usually from massive dams, like the Hoover Dam, or sources like Niagara Falls. It’s not necessarily an option for an individual homeowner. Building dams can also have unintended environmental impacts.
If you live in an area where there’s a dam or natural water resource, you can ask about how power is generated. The more hydroelectricity available, the cleaner the energy you’re using.
Solar power is probably the fastest growing green energy source and one of the most popular. Using solar panels, you can harvest the power of the sun to generate electricity.
Today’s solar panels are much more efficient. You can scale the size of your installation to your home or building. Solar contractors can help you determine what you’d need to power part or all of your home.
When it comes to renewable resources, wind power is one of the most visible. You may have seen wind farms, which have massive windmills spinning to generate power.
Since the equipment takes up so much space, wind isn’t a practical solution for homeowners yet. Right now, though, wind farms are a great choice for large-scale operations.
Ask about the green initiatives been taken in your area. There may be potential for adding more wind power to the grid.
Renewable energy from biomass comes from a few different sources. One example of biomass is ethanol produced from corn. Another is gases captured from landfill sites.
Biomass is renewable, because the sources can be grown quickly. A new crop of corn can be grown each year. While it’s growing, the corn acts as a carbon sink.
Biomass does produce greenhouse gases, so it isn’t emission free. There’s also some concerns about using food crops or precious forest resources this way. Nonetheless, biofuels are accessible and can be used for a wide variety of activities.
One of the best renewable energy sources is right beneath our feet. People have used the Earth’s internal heat for almost all of history. In Iceland, geothermal energy accounts for almost all of the energy used for heating homes.
As you can see, there are plenty of renewable sources of energy to choose from. If you’re thinking about going green, switching your energy source is a great step to take.
