Green Power Partnership Glossary

A –  B –  C –  D –  E –  F –  G –  H –  K –  M –  N –  O –  P –  R –  S –  U –  V
A criterion often applied to greenhouse gas (GHG) project activities, stipulating that project-based GHG reductions should only be quantified if the project activity "would not have happened anyway"—i.e., that the project activity would not have been implemented in its baseline scenario. Additionality is a test used only for project offsets and not for RECs.
Annual Consumption
Annual consumption refers to the amount of electricity used in one year and is typically measured in kilowatt-hours (kWh). This information is available on your electricity bill or by contacting your energy provider.
Caused by man or resulting from human activities. Used in the context of greenhouse gas emissions produced as a result of human activities.
Any material or fuel produced by biological processes of living organisms, including organic non-fossil material of biological origin (e.g., plant material), biofuels, biogenic gas, and biogenic waste.
An energy attribute certificate that is traded with the underlying energy produced.
Carbon Dioxide
Carbon dioxide (CO2) is an atmospheric gas that is a major component of the carbon cycle. Although produced through natural processes, carbon dioxide is also released through human activities, such as the combustion of fossil fuels to produce electricity. Carbon dioxide is the predominate gas contributing to the greenhouse effect, and as such is known to contribute to climate change.
Carbon offsets
Represent a quantity of GHG emissions reductions, measured in metric tons of carbon dioxide-equivalent (CO2e) that occur as a result of a discrete project. The emissions reduction from that project can be sold to enable the purchaser/owner to claim those GHG reductions as their own. Renewable energy is one of many possible offset project types.
Certification and Verification
Refers to the certification and verification of green power products. See the Certified and Verified Products section of this website for more information.
Climate in a narrow sense is usually defined as the "average weather," or more rigorously, as the statistical description in terms of the mean and variability of relevant quantities over a period of time ranging from months to thousands of years. The classical period is three decades, as defined by the World Meteorological Organization (WMO). These quantities are most often surface variables such as temperature, precipitation, and wind. Climate in a wider sense is the state, including a statistical description, of the climate system.
Combined Heat and Power
Combined heat and power (CHP), also known as cogeneration, is an efficient, clean, and reliable approach to generating power and thermal energy from a single fuel source. CHP is not a specific technology but an application of technologies to meet an energy user's needs. CHP systems achieve typical effective electric efficiencies of 50 to 80 percent — a dramatic improvement over the average efficiency of separate heat and power. Since CHP is highly efficient, it reduces traditional air pollutants and carbon dioxide, the leading greenhouse gas associated with climate change. Visit EPA's Combined Heat and Power Partnership Web site for additional information.
Commodity Electricity
Is physical electricity in the absence of the technological, environmental, social, and economic benefits associated with a specific generation source. These benefits are transferable over geographic distance through a tradable instrument called a renewable energy certificate (REC) and can be re-associated with the physical electricity at the point of use.
Community Choice Aggregation (CCA)
Also known as Municipal Aggregation, CCAs allow communities to determine their electricity generation sources by aggregating the community load and purchasing electricity from an alternative suppliers while still receiving transmission and distribution service from their existing provider. Currently authorized in California, Illinois, Ohio, Massachusetts, New Jersey, and Rhode Island, as enabled by state legislation.
Competitive Markets
Until recently, most consumers received generation, transmission, and distribution services from one local utility company. As a regulated monopoly, the utility was given an exclusive franchise to provide electricity to consumers in any particular community. Rates were set, and consumers had little choice but to pay that rate. In recent years, however, many states have restructured their electricity industry and are now allowing consumers to choose from among competing electricity suppliers.

In these states with retail competition, sellers of electricity obtain power by contracting with various generation sources and setting their own price. Consumers in these states have the opportunity to choose their energy provider and purchase products based on the price or type of power supplied to their home or business. Some consumers are exercising this choice and switching to accredited "green power" resources. In states that have not restructured their electricity markets, consumers interested in purchasing renewable energy now have the option to participate in green pricing programs offered by their local utility.
Conventional Power
Power that is produced from non-renewable fuels, such as coal, oil, natural gas, and nuclear. Conventional fuels are finite resources that cannot be replenished once they are extracted and used.
Distributed Generation
Small, modular, decentralized, grid-connected or off-grid energy systems located in or near the place where energy is used.
Electricity Supplier
As states restructure their electricity markets, an increasing number of customers will be able to choose from a range of electricity suppliers who market different types of power products, including green power. In states without restructured electricity markets, local utilities may offer green pricing programs that enable customers to elect to have their utility generate a portion of their power from renewable sources. To find out about green power products in your area, visit the Green Power Locator.
The release of a substance (usually a gas when referring to the subject of climate change) into the atmosphere.
Energy Efficiency
Refers to products or systems using less energy to do the same or better job than conventional products or systems. Energy efficiency saves energy, saves money on utility bills, and helps protect the environment by reducing the demand for electricity. When buying or replacing products or appliances for your home, look for the ENERGY STAR® label — the national symbol for energy efficiency. For more information on ENERGY STAR-labeled products, visit the ENERGY STAR Web site Exit.
Energy Marketers
See Electricity Supplier.
Executive Order (EO) 13693
Planning for Federal Sustainability in the Next Decade signed on March 19, 2015, EO 13693 Exit, builds upon previous EOs sets ambitious mandates to reduce the greenhouse gas (GHG) emissions by 40 percent across all federal operations and federal supply over the next decade, relative to 2008 levels.
Fossil Fuels
Fossil fuels are the nation's principal source of electricity. Fossil fuels come in three major forms: coal, oil, and natural gas. Because fossil fuels are a finite resource and cannot be replenished once they are extracted and burned, they are not considered renewable.
The act of transforming energy into electricity.
Global Climate Change
Climate change refers to any significant change in measures of climate (such as temperature, precipitation, or wind) lasting for an extended period (decades or longer). Climate change may result from:
  • Natural factors, such as changes in the sun's intensity or slow changes in the Earth's orbit around the sun
  • Natural processes within the climate system (e.g. ,changes in ocean circulation)
  • Human activities that change the atmosphere's composition (e.g., through burning fossil fuels) and the land surface (e.g., deforestation, reforestation, urbanization, desertification)
Greenhouse Gases (GHGs)
Any gas that absorbs infrared radiation in the atmosphere. Greenhouse gases include, carbon dioxide, methane, nitrous oxide, ozone, chlorofluorocarbons, hydrochlorofluorocarbons, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride
Green Power
Renewable energy resources such as solar, wind, geothermal, biogas, biomass, and low-impact hydro generate green power. A green power resource produces electricity with no fossil-fuel based GHG emissions, has a superior environmental profile to conventional power generation, and must have been built after the beginning of the voluntary market (1/1/1997).
Green Power Marketers
Due to increased customer awareness of the environmental implications associated with conventional power generation, a growing number of utilities and other types of energy service providers have begun offering green power products. The term "green power marketers" usually refers to energy providers operating in states that permit retail competition in the electricity markets. In states that do not allow this retail competition, many utilities have begun offering green power options under what are typically referred to as green pricing programs. To learn more about green power products in your area and whether your utility offers a green pricing program, visit the Green Power Locator.
Green Power Product
Green power electricity products are supplied from renewable energy resources that provide the highest environmental benefit. Green power sold by regulated utilities is called green pricing, and when sold in competitive electric markets, green power is called green marketing.
Green Pricing
Some power companies are now providing an optional service, called green pricing, which allows customers to pay a small premium in exchange for electricity generated from green power resources. The premium covers the increased costs incurred by the power provider (i.e., the electric utility) when adding green power to its power generation mix. To find out if your utility offers a green pricing program, refer to the Green Power Locator.
Green Power Purchasing
Green power can be purchased nationwide from several sources. Green power marketers offer green power products to consumers in deregulated markets, such as New Jersey, Pennsylvania, and New England. In states that do not allow retail competition in the electricity markets, many utilities offer green power products through green pricing programs. In addition, all customers nationwide have the opportunity to buy green power and stimulate the development of renewable generation sources through renewable energy certificates. Finally, customers can choose to install on-site generation, such as solar photovoltaics.
Hydroelectric Power (Large)
The process of generating electricity by harnessing the power of moving water is called hydroelectricity. Hydroelectric power (hydropower) is generated by forcing water that is flowing downstream, often from behind a dam, through a hydraulic turbine that is connected to a generator. The water exits the turbine and is returned to the stream or riverbed. Much of the hydroelectricity in the United States is generated at large facilities and in the Pacific Northwest, where it meets about two-thirds of the electricity demand. In the United States, hydroelectricity contributes about 10 percent of the total electricity supply.
Hydro (Small-scale)
In addition to very large hydroelectric plants in the West, the United States also has many smaller hydroelectric facilities. Like large plants, small-scale hydroelectric systems capture the energy in naturally flowing water and convert it to electricity. Although the potential for small hydroelectric systems depends on the availability of suitable water flow, these systems can provide cheap, clean, reliable electricity where the resource exists.
A kilowatt-hour (kWh) is a standard metric unit of measurement for electricity.
One kilowatt-hour (kW) is equal to 1,000 watt-hours (Wh).
A watt-hour is the amount of energy delivered at a rate of one watt (W) for a period of one hour.
One watt is the amount of power rate of one joule of work per second of time.
Example: A 100 watt light bulb in use for 10 hours uses 1000 watt-hours, or 1 kilowatt of electricity. (100 watts x 10 hours = 1000 watt-hours = 1 kWh)
A megawatt-hour (MWh) is equal to 1,000 kWh.
Metric Ton
Common international measurement for the quantity of greenhouse gas emissions. A metric ton is equal to 2205 lbs or 1.1 short tons.
Net Metering
A method of crediting customers for electricity that the customer generates on site in excess of their own electricity consumption. Customers with their own generation offset the electricity they would have purchased from their utility. If such customers generate more than they use in a billing period, their electric meter turns backwards to indicate their net excess generation. Depending on individual state or utility rules, the net excess generation may be credited to their account (in many cases at the retail price), carried over to a future billing period, or ignored.
"New" Renewables
The voluntary green power market came into existence in the late 1990's. January 1, 1997 is considered a definitive point in time when green power facilities could be adequately identified as having been developed to serve the green power marketplace. Green power facilities placed into service after January 1, 1997 are said to produce "new" renewable energy. The "new" criterion addresses the additionality requirement for the voluntary market.
On-Site Renewable Generation
Electricity generated by renewable resources using a system or device located at the site where the power is used. On-site generation is a form of distributed energy generation. For more information about distributed energy technologies that are renewable and non-renewable, visit the Department of Energy's Distributed Energy Resources Web site Exit.
Power Purchase Agreement (PPA)
A type of contract that allows consumers, typically large commercial entities, to form an agreement with a specific energy generating unit. These types of contracts, typically secure a long term stream of revenue for an energy project by providing the energy offtaker a steady cost of electricity.
Renewable Energy
The term renewable energy generally refers to electricity supplied from renewable energy sources, such as wind and solar power, geothermal, hydropower, and various forms of biomass. These energy sources are considered renewable sources because their fuel sources are continuously replenished.
Renewable Energy Resources
See Green Power Market section of this website.
Renewable Energy Certificates (RECs)
Also known as green tags, green energy certificates, or tradable renewable certificates. RECs represent the technology and environmental attributes of electricity generated from renewable sources. RECs are usually sold in 1 megawatt-hour (MWh) units. A certificate can be sold separately from the underlying generic electricity with which it is associated. Once the REC is sold separately from the underlying electricity, the electricity is no longer considered renewable. RECs provide buyers flexibility to offset a percentage of their annual electricity use when green power products may not be available locally.
Renewable Portfolio Standard
The requirement that an electric power provider generate or purchase a specified percentage of the power it supplies/sells from renewable energy resources, and thereby guarantee a market for electricity generated from renewable energy resources.
Retail Competition
In states with retail competition, consumers have the opportunity to choose their energy provider and purchase products based on the price or on the source of power supplied to their home or business.
Scope 1 emissions
Emissions from operations that are owned or controlled by the reporting company.
Scope 2 emissions
Indirect emissions from the generation of purchased or acquired electricity, steam, heat or cooling consumed by reporting company.
Scope 3 emissions
All indirect emissions (excluding Scope 2 emissions) that occur in the value chain of the reporting company, including both upstream and downstream emissions.
Short Ton
Common measurement for a ton in the United States. A short ton is equal to 2,000 lbs or 0.907 metric tons. See metric ton.
The energy attribute that is separate, and may be traded separately, from the underlying electricity produced.
A utility is a municipal or private business that provides electricity to the public and is subject to governmental regulation.
A term that refers to the year that purchased green power was generated.

Green Power Partnership Frequently Asked Questions


EPA's Green Power Partnership

Q. What is the Green Power Partnership?
A. EPA's Green Power Partnership is a free, voluntary program that encourages organizations to buy green power as a way to reduce the environmental impacts associated with purchased electricity use. Started in 2001, the Partnership currently works with more than a thousand partners voluntarily purchasing billions of kilowatt-hours of green power annually.

Green Power

Q. How does EPA define green power?
A. EPA defines green power as environmentally preferable electricity produced from a subset of renewable resources, including solar, wind, geothermal, biogas, eligible biomass, and low-impact hydropower.
Q. What makes it greener than other power?
A. Green power resources produce electricity with an environmental profile superior to conventional power technologies, and produce no fossil-fuel based greenhouse gas emissions, helping protect human health and the environment.
Q. Is green power available in most of the United States, or only in certain areas?
A. Green power is available to every single business, institution, government agency, homeowner, apartment dweller, and every other electricity user in the United States. There are three green power product options available:
  1. First, currently, more than 800 utilities offer green power products to customers. These products allow customers to purchase some portion of their electricity from renewable resources—almost always at a higher price, but sometimes offered with price-hedging benefits.
  2. Second, regardless of whether a buyer has access to a utility green power product, any consumer or business in the United States can buy green power through renewable energy certificates (RECs). A REC represents the generation of one megawatt-hour (MWh) of electricity from an eligible source of renewable energy and its associated environmental attributes. RECs can be acquired separately from electricity service. Combined, RECs and plain grid electricity produce green power.
  3. Last, a prospective buyer can also investigate the option of installing an on-site system on their business or residence.

    Buyers can learn more about these options by downloading The Guide to Purchasing Green Power from the Green Power Partnership website. The guide helps explain the buying process as well as the benefits of each product option.

    To assist prospective buyers, the Green Power Locator offers a state-by-state, list of local utilities and renewable energy certificate marketers that provide green power products in their area.

EPA's Green Power Communities

Q. What is the Green Power Community program?
A. The Green Power Community program is an EPA–designed platform within the Green Power Partnership to promote community-based support for green power. EPA is working to reduce greenhouse gas emissions in the United States and expand the nation's renewable energy supply by driving demand for green power among communities across the country.
Q. What are the benefits to joining the Green Power Community Program?
A. For most municipalities, electricity usage is the single-largest source of greenhouse gas emissions. By using green power, a local government can dramatically reduce its carbon footprint, demonstrate civic leadership, increase citizen pride, improve public health, and enhance its community image. Moreover, by answering this call to action, a community, its citizens, and businesses can collectively move the nation to a clean energy future and inspire other communities to do the same.
Q. How much green power are these communities purchasing?
A. As of January 1, 2016 there are 60 EPA Green Power Communities collectively buying more than six billion kWh of green power annually, equivalent to the electricity use of more than 580,000 average American homes.
Q. What is Community Choice Aggregation?
A. Community choice aggregation (CCA) is a state policy that enables local governments to aggregate electricity demand within their jurisdictions in order to procure alternative energy supplies while maintaining the existing electricity provider for transmission and distribution services. These are also known as Municipal Aggregations. Many states passed CCA laws as part of electric restructuring legislation in the late 1990s and early 2000s. States that have passed CCA laws include California (2002), Illinois (2009), Massachusetts (1997), New Jersey (2003), Ohio (1999), and Rhode Island (1997).
