Understanding the Environmental Impacts of Electricity: Product Labeling and Certification

Electricity consumers are increasingly gaining the ability to choose among power options from either their current electric utilities or from alternative power providers. In order to help consumers make informed decisions about their electricity purchases and to compare alternatives, many states are requiring electricity providers to disclose information regarding the fuel sources used togenerate electricity and the associated environmental impacts. Like nutrition labels, environmental disclosure labels present the content or sources of electricity and are typically included with electricity bills and in product offers. These labels allow consumers to compare the environmental impacts of standard and cleaner power options, which are typically available. This paper discussesclean, green power options available to power purchasers and the tools and information that can be used to make more sustainable power purchase decisions.
