Green Power Options

One way you can do your part to reduce your carbon footprint is by switching to green power.

Green power is a subset of renewable electricity and represents those renewable energy resources and technologies that provide the highest environmental benefit.

Currently, across the U.S., 20% of delivered electricity from utilities is renewable electricity. The more people who switch to using green power, the more our health and environment will be protected.

Green power is available from a variety of suppliers and comes in a range of supply options, which each have its own set of unique characteristics.

The diversity in supply options allows consumers to customize a green power procurement approach to best meet their financial, environmental, and operational objectives. To learn more about what options to consider when selecting a green power supply, please visit our Green Power Procurement Considerations.

  • Utility Green Power Products (Green Pricing) – Many households have the option to simply opt for green power for their electricity. Utility green power products – often referred to as green pricing  – are offered directly from your utility supplier so you can get information on these options by contacting your utility. You can also click hereto access third-party certified green power products by state.
  • Competitive Green Power Products – Some customers may live in what are referred to as deregulated electricity markets. These are areas where other suppliers, besides your utility, can offer alternative energy sources. If you live in a deregulated state, you can purchase green power from an alternative electricity supplier who is not your default utility supplier. You are billed for the costs of the green power through your utility bill even though it comes from a different source. It basically operates similar to a utility offered green power product, but you can choose from multiple suppliers. Click here for descriptions and links to competitive green power products.

Community Choice Aggregation (CCA) – In some states, local governments can buy power from an alternative green power supplier on behalf of their residents. For more information and a list of states where CCA’s are available, visit


  • Shared Renewables (Community Renewables) Many households also have access to what are called “shared or community renewables.” Community Solar is the most popular of those. Specifically, you can buy, lease, or subscribe to a portion of electricity output from a shared system, such as a solar or wind farm.

  • Self-Supply – Households can also provide their own green power by installing solar panels on their roof-tops to power their homes or even a windmill on their property. Roof-top solar is the most popular form of residential self-supply.
  • Retail Renewable Energy Certificates – This option is available to all consumers across the U.S. Retail RECs provide no physical delivery of electricity to customers. The customer is purchasing power from a separate entity than the one selling them the REC instrument. Find out where to get a third-party certified REC here.

What else should I look for when buying green power?

  • How do I know that the green power I’m purchasing is really green? Choosing Green Power that is third-party certified is the best guarantee. When your green power is certified “green” you can be sure that your purchase meets nationally accepted environmental standards for resource and product quality and content. Learn more about certification/verification here. If an option you are interested in is not third-party certified, it does not mean that it isn’t green. Knowing the fuel type is another way to evaluate the environmental quality of the renewable electricity you are supporting. Look for zero to low emissions fuels as part of the power generation process.
  • What Are Renewable Energy Certificates and how do they work? You may not know it, but every time you purchase green power or supply it for yourself, that green power is represented by Renewable Energy Certificates or REC (1REC = 1MWh). RECs are very important for supporting the growth and credibility of the green power market. Your provider of green power must retire the REC on your behalf. This is the only way to verify you are using renewable electricity. Most providers do this as a service for their customers. Self-suppliers generate their own RECs and need not worry about retiring.
