Green Energy

Incorporating green energy into your procurement strategy is an easy way to reach your sustainability goals.

What is Green Energy?

Green/Renewable energy is energy that is not generated by fossil fuels (coal, natural gas, and oil). Renewable energy sources are naturally replenished overtime.

Types of Renewable Energy


Energy from the sun that is converted into electricity or heat using solar panels. Solar energy is the cleanest and most abundant renewable resource available.


Wind energy is converted into electricity using turbines. Wind farms use numerous turbines positioned in water or over a large area of land to generate electricity.


Using water to generate electricity or power machinery. The kinetic energy of flowing water powers turbines that produce electricity.


Plant material and animal waste (biomass) are used as fuel to boil water. The energy from the resulting steam is used to power turbines and generators that create electricity.


Heat from within the Earth is harnessed and brought to the surface to power turbines that generate electricity. Geothermal energy can also be used to directly heat homes and buildings.

How do you buy green energy?

You can incorporate renewable energy into your strategy by purchasing RECs or by owning an onsite or offsite renewable asset. Most of our clients choose to buy RECs because it is the easiest and most cost-effective way to “go green.”

What is a REC?

A Renewable Energy Credit (REC) is tradable, non-tangible proof that 1 megawatt-hour (MWh) of electricity has been generated from a renewable resource and fed into the grid.

When it comes to RECs, you have options.

Some suppliers allow you to specify which type of RECs you would like to purchase as part of your electricity agreement. The options vary based on region and supplier availability.

Multiple Mix

This type of REC pulls green energy from multiple national renewable energy sources.


You can request that the energy for the RECs is sourced from a specific state or region.


You can indicate which renewable source you would like your RECs to be sourced from, such as solar or wind.

Green Energy FAQs

There is a premium associated with purchasing RECs. Currently, premiums are between $.001 and $.002 per kWh, but this could vary based on the type of REC you choose.
Most likely not. The grid contains both renewable and non-renewable energy. If you purchase RECs, you ensure that green energy gets to the grid. But unless you own a renewable asset tied to your facility, you won’t know for sure if the electricity you’re receiving is truly green.
While most green energy talk revolves around power generation, renewable natural gas (RNG) does exist. However, RNG isn’t as prevalent as renewable electricity because most of the US currently lacks the infrastructure to clean and transport the gas to utilities.
