To the maximum extent practical, RECs used by AMP for EcoSmart Choice are Green-e® certified by the Center for Resource Solutions and/or are RECs generated within AMP member states. They are currently sourced from hydroelectric, landfill gas, biomass or wind facilities.


Hydroelectricity is the term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water. The force of the water drives a turbine which in turn powers a generator, producing electricity which can be used on-site or transported to other regions.

Landfill Gas to Energy

Instead of escaping into the air, landfill gas can be captured, converted, and used as an energy source. Using landfill gas helps to reduce odors and other hazards associated with landfill emissions, and it helps prevent methane from migrating into the atmosphere and contributing to local smog and global climate change.

Wind power is the ability to make electricity using the air flows that occur naturally in the earth’s atmosphere. Wind turbine blades capture kinetic energy from the wind and turn it into mechanical energy, spinning a generator that creates electricity.

Biomass is fuel that is developed from organic materials, that when burned or decomposed, can be used to create electricity. Some examples of materials that make up biomass fuels are: scrap lumber, forest debris, certain crops, manure and some types of waste residues.
