What are renewable energy projects?
Renewable energy projects generate energy from renewable sources. However, that renewable energy joins energy from non-renewable sources in a grid where electricity flows along the path of least resistance. In order to track and claim energy from renewable sources in this blended system, companies purchase energy attribute certificates (EACs). One EAC represents 1,000-kilowatt-hours (or 1-Megawatt-hour) of electricity that has been generated and delivered to the electricity grid from a renewable source.
Renewable energy can be generated from a variety of sources
By purchasing EACs, organizations support projects that reduce the greenhouse gas emissions from the power grid by supplying energy from a diverse collection of renewable sources.
As wind turns the propeller of wind turbines, it generates either mechanical power or electricity (also known as wind power).
Solar energy (light and heat from the sun) is harnessed and converted into an electric current.
Landfill-gas-to-energy (LFGTE) projects capture methane gas for electricity and heat, turning a potent greenhouse gas into energy.
These projects harness natural thermal energy by pumping hot water deep below the Earth’s surface and creating steam.
Biogas systems capture methane gas through a process called anaerobic digestion and convert the gas into energy.
Hydropower projects use running water, without reducing its quantity, to produce electricity (also known as hydroelectricity)
International Renewable Energy Tracking Systems
EACs go by different names within the global energy market depending on location, but each type represents the same 1,000 kwh measurement. Below are some of the most common EACs in the markets we serve.
Renewable Energy Certificates (RECs)
Guarantees of Origin (GOs)
International RECs (I-RECs)
EAC Tracking & Verification
Energy attribute certificate purchases are tracked on public registries managed by a variety of third-party organizations around the world. GreenPrint manages the whole process, from purchasing EACs to retiring them on third-party-verified public registries in our clients’ names.
Ridge Crest Wind
Located in Logan County west of the town of Peetz in northeastern Colorado, the Peetz Table Wind Farm consists of 33 turbines that are each rated at 0.9 MW and has a total installed capacity of 29,700 kW. The Peetz Table is a plateau that provides access along its southern edge in Colorado to some of the best wind resources on the High Plains. It supplies zero-emissions energy to the North American power grid and avoids carbon emissions from fossil-fuel-based electricity.
