What are renewable energy credits (RECs)?

Download Article

A renewable energy credit is a certificate (also known as renewable energy certificate or REC) that represents energy created by renewable sources like solar, wind, and other zero-emission sources. A REC is a non-tangible item that gives someone the property rights to renewable energy that’s been created and its environmental benefits. They allow businesses and homeowners to be more sustainable by investing into renewable energy. When energy providers offer renewable energy plans that rely on RECs, it allows buyers to participate in renewable energy generation without installing complex infrastructure, or renewable energy systems (like solar panels).^{[2]

When people and organizations purchase RECs, they receive documentation that certifies where that energy came from. When your home or business receives physical electricity through the utility grid, there’s no way to tell where the energy came from or how it was generated, but the RECs work by substantiating the claims that a company, office, or household owns renewable electricity that was generated.^{[3]

- Once generated, renewable energy certificates can be kept or sold. When a REC is purchased, the buyer becomes the owner of that renewable energy source. Therefore, that buyer can claim that the electricity they consume comes from a renewable energy resource with minimal or zero emissions.
- A REC can only be retired once each Mwh unit has a unique tracking number tying it to its attributes in its tracking system. By purchasing a REC, you’re able to support renewable energy production without having to install or maintain renewable energy sources at home (like solar panels or wind turbines). Instead, you can simply switch providers and enroll in a renewable energy plan like Indra Energy to go green and reduce your carbon footprint without any complex equipment or expensive installation.

How are renewable energy credits generated?

To be more precise, a single renewable energy credit is generated whenever renewable energy sources (like solar panels or wind turbines) produce one megawatt-hour (MWh) of electricity. For instance, if a geothermal heat pump produces 10 MWh of electricity, then the owner of the pump has ten renewable energy credits to use or sell.^{[4]

Since all of our electricity flows into the same grid, it’s impossible to track what energy is renewable, and what isn’t. RECs identify the renewable energy once it’s produced and before it’s added into our electrical grid.
- Each REC has unique tracking and certification that includes information about the date the energy was generated, where it was generated, and what type of renewable source it came from. RECs are certified through independent organizations, like the Green-e Energy program. This certification ensures that RECs are real, verifiable, and only counted in the grid once.

You can get RECs by generating, purchasing, or re-bundling them. There are three main ways to get RECs as a business owner or homeowner. First, you can generate your own RECs by installing a renewable energy source at your home—like solar panels, heat pumps, or mini wind turbines. If you want to generate renewable energy in your home without installing equipment, you can switch to a renewable energy company like Indra Energy. Indra Energy offers 100% renewable energy plans, and you can quickly switch to their environmentally-sustainable service with zero hassle.
- Plus, Indra Energy offers both month-to-month and fixed rate plans. If you’re still unsure about using renewable energy in your home, you can try it out with one of their monthly into-to-variable rate plans.

Alternatively, you can get involved in re-bundling, which is a more complicated practice that’s primarily used by corporations. RECs can be purchased as “bundled” or “unbundled” from the electricity that produced them. If you purchase unbundled renewable energy credits, you can then contractually re-bundle the RECs with electricity from another project.
- In this process, the RECs from one renewable electricity project are sold and replaced by new, cheaper RECs from a separate renewable energy project.^{[6]

Install a geothermal or air source heat pump. Geothermal heat pumps and air source heat pumps both naturally extract heat from the environment to be used as energy—giving your home hot water and natural heat. While geothermal heat pumps draw heat from the ground, air source heat pumps take heat from the surrounding air.^{[16]

- Both types of heat pumps are forms of renewable energy, but geothermal pumps are considered more energy efficient due to ground temperatures being more stable than air temperatures. However, geothermal heat pumps are much more expensive and require a much more complex installation process.
When you picture a wind turbine, you’re probably thinking of the massive, skyscraper-sized pinwheel structures you see while driving through open farmland. However, smaller wind turbines are available as an excellent renewable energy source for homeowners. They can be installed as a free-standing pole or directly onto the building. As the wind blows, the blades will turn, driving the internal turbine and generating power.^{[18]

Biomass heating systems use organic materials like wood pellets, chips, and logs, to create heat and hot water. In a biomass system, these organic materials are burned in order to generate electricity in your home. Compared to fossil fuels like coal and oil, the wood burned in a biomass system generates much less carbon—about the same amount as the tree absorbed during the time that it was growing.^{[19]

Install a solar power or solar heating system. Solar power can be used as a renewable energy source through solar panels and solar water heaters—and it doesn’t even have to be sunny for these systems to work efficiently! Solar photovoltaic panels are one of the most recognizable types of renewable energy. The panels can be installed on the roof, and they convert the sun’s rays into energy that can be used to warm your home, power your devices, and provide hot water.^{[20]

- However, installing solar panels as a homeowner can be a costly and time-consuming endeavor (even though solar panels will likely still save you money in the long-term).
- As an alternative, solar water heaters use sunlight channeled through solar collectors to capture and retain the sun’s heat in an insulated storage tank. This tank then heats the circulating water to provide it to your home.^{[21]

FAQs About Renewable Energy Credits

Download Article

Renewable energy is energy generated from natural sources like the sun, wind, biomass, and water. Typically, renewable energy sources are things that can be naturally replenished and don’t emit harmful greenhouse gases. Often referred to as “green” or “clean” energy, renewable energy is a step away from traditional energy sources like fossil fuels (coal and oil) that emit greenhouse gases and do irreparable harm to the environment.^{[23]

RECs are bought and sold on two different markets: compliance markets and voluntary markets. Renewable portfolio standards typically drive compliance market prices, while voluntary markets are usually driven by climate-related sustainability goals. The prices in each of these markets vary greatly depending on these factors as well as national and statewide economics, but compliance markets are typically more expensive than voluntary ones.^{[24]

RECs are primarily designated by state law as a way to substantiate claims in the U.S. renewable electricity market. When a corporation, household, non-profit, business, or other organization has to or choose to legally prove how they are offsetting their carbon footprint, renewable energy credits are a way to do it. RECs are supported by governmental entities, regional electricity authorities, NGOs, trade associations, and U.S. case law.^{[25]

Offsets and renewable energy credits both represent the environmental benefits of actions taken to reduce greenhouse gas emissions. RECs represent 1 MWh of generated renewable electricity, while offsets represent a metric ton of avoided or reduced emissions. Fundamentally, a REC and a carbon offset have different criteria for qualification and crediting—RECs are focused on crediting the creation of green energy, while offsets are focused on crediting the reduction of harmful energy.^{[26]
