The Currency of Green Power
When a renewable energy facility, such as a wind farm or solar plant, generates electricity, it creates two distinct products. The first is the actual electricity that is fed into the power grid. The second is a Renewable Energy Credit (REC), which is a certificate that embodies the ‘green’ or ‘renewable’ attribute of that electricity. Each REC is uniquely numbered and tracked, serving as proof that one megawatt-hour (MWh) of clean energy was produced and sent to the grid.
How Film Productions Use RECs
It is often impractical or impossible for a temporary film production to install its own solar panels or wind turbines to power a soundstage. To address their Scope 2 emissions (from purchased electricity), productions can participate in the REC market. After calculating their total electricity consumption for the shoot, a production can purchase an equivalent number of RECs. When a production buys and ‘retires’ a REC, they are effectively claiming the environmental benefit of that clean energy. This allows the production to legally and verifiably state that their electricity usage was ‘powered by 100% renewable energy,’ even though the actual electrons flowing to their set were from the general grid mix. This market-based mechanism provides a crucial revenue stream to renewable energy developers, incentivizing the creation of more clean power.
RECs vs. Carbon Offsets
It is important to distinguish between RECs and carbon offsets. RECs are specifically used to address the carbon footprint of electricity consumption (Scope 2 emissions). Carbon Offsets, on the other hand, are a broader tool used to compensate for other types of emissions (like those from air travel or generator fuel) by funding projects that actively reduce, avoid, or sequester greenhouse gases, such as reforestation or methane capture initiatives.
