Buying Green Power

Green Power Benefits

Your organization's purchased electricity use can be a significant source of air pollution and greenhouse gas emissions. Buying green power can help reduce your organization's environmental impact while also providing valuable benefits:

  • Reduce your organization's carbon footprint associated with purchased electricity
  • Hedge against future electricity price increases (certain products)
  • Serve as a brand differentiator
  • Generate customer, investor, or stakeholder loyalty and employee pride
  • Create positive publicity and enhance your organization's public image
  • Demonstrate civic leadership

The price paid for green power can vary widely by:

  • Resource type (e.g., solar, wind, biomass)
  • Resource geography
  • Product type (renewable energy certificate [REC], utility pricing, fixed pricing)
  • Contract duration
  • Vendor

The Green Power Locator lists residential price premiums for some green power products. Economies of scale may provide large volume buyers lower price premiums than the residential rates imply. EPA recommends seeking multiple price estimates from suppliers to assess the going market rate for green power products that meet your organization's purchase specifications.

Partnership Perspective

EPA can support your organization in communicating the benefits of your green power purchase to stakeholders. We lend valuable credibility to your organization's actions, helping verify that your purchase meets nationally accepted standards for size, content, and resource base.
