Renewable energy is becoming cheaper and more plentiful, but it can still be time-consuming and expensive to make the switch for your home.

Thankfully, now there is an easy way you can help the environment without installing solar panels. Enter Arcadia Power, a company that promises to match 50% of your energy bill with clean energy—at no extra cost. Or you can go 100% clean for just a few extra dollars.

Here’s how it works:

To sign up, just enter your local utility information (Arcadia Power is available in all 50 states) and your preferred method of payment.

The Arcadia platform monitors your monthly electricity usage and buys Renewable Energy Certificates (RECs) from wind farms to match that usage.

You get a single bill that includes your local utility charge along with the clean energy matches. You can track your impact monthly with your personalized energy dashboard.

How is that possible?

Arcadia Power accomplishes this through the power of RECs. Each time a renewable energy generator produces one megawatt-hour of electricity, one REC is created. Each one is “a specific amount of electricity produced and delivered to the power grid by a renewable resource such as wind or solar,” states the EPA

So buying RECs means more green energy is pumped into the grid, a form of direct investment in renewable energy farms.

That’s where Arcadia Power comes in. It acts as a middleman, paying your electricity to the local utility and keeping track of your power consumption. When you pay your bills to Arcadia Power, a small premium goes to RECs, which are given to wind farms to produce more electricity.

So what are you waiting for? Sign up and do your part!
