Environmental Impact of Switching to Solar in Portland
There are a few big reasons why many people are considering solar energy: to help their wallet and the environment. Something many might be thinking about is how much can they really help save the environment by switching to solar power anyway? One thing you should keep in mind is your overall carbon footprint. For example, if you spend lots of time commuting to work and have an electric vehicle, you can use solar energy for your home to power your EV and therefore help offset your carbon emissions. If you go solar, your carbon emissions can be lowered by about 40 pounds every year. Since solar energy is renewable and makes electricity without releasing carbon emissions, making the switch to solar power is one easy step you can take to help protect the environment.
