RECs (Renewable Energy Certificates) are used to track and validate the production of 1 MWh (megawatt hour) of renewable energy by any renewable source (Solar, Hydro, Wind).
Traditionally, solar panels are installed on the customer’s roof minimising the dependency on the grid for electricity ultimately reducing CO2 emissions. However, limited roof space prevents production of 100% onsite consumption.
Good news: there is an existing framework practiced globally enabling you as the consumer to “use” renewable energy without physically consuming it. With every 1MWh of “dirty” energy you consume, you can purchase 1MWh of renewable energy (represented by a REC) produced in another location. Using this framework you can be 100% carbon neutral in your consumption.
Purchasing RECs is the most effective path to take in order to achieve the goal of being 100% renewable or carbon-neutral. Many big corporations are adopting this approach to meet their sustainability targets. A total of 191 companies (RE100) (http://there100.org) have officially made their commitment to bring the company towards being 100% renewable.
