Legal indoor marijuana grows are consuming energy at an exorbitant rate, according to a recent report by a cannabis industry data provider.

While most of legalized marijuana's effects on communities are measured in terms of dollars and crime statistics, electricity usage is becoming an issue of growing concern among environmentalists and industry folk alike. According to pot data firm New Frontier, the marijuana industry used over $6 billion in energy last year, or around 1 percent of the country's energy output — and that number is only expected to grow.

“Both operators and legislators will need to be very mindful of the high energy demands of the legal cannabis industry," New Frontier Founder Giadha Aguirre De Carcer said in a statement. "Companies that adopt the most energy-efficient practices will have an important cost advantage as the industry becomes more competitive and prices fall, and states that prioritize energy efficiency will reduce the fast-growing industry’s impact on the grid and on the environment."

Because of the myriad local regulations that surround it, growing legal marijuana is often confined indoors, requiring the use of intense growing lights, dehumidifiers and ventilation and watering systems. Although some rural communities in southern Colorado, such as Pueblo County, allow commercial outdoor marijuana grows and greenhouses, most municipalities ban them in attempts to keep the grows discreet and less accessible.

As of February 4, the City and County of Denver had 371 registered medical marijuana cultivation facilities and 196 recreational grows, almost all of which are indoor/warehouse operations. The State of Colorado had over 1,200 active licenses for legal marijuana grows as of February 1.

A recent NPR report cited a 10,000-square-foot warehouse grow with LED lights using roughly $12,000 worth of energy per month to cultivate. Some Denver warehouse grows, such as LivWell Enlightened Health's monster facility in north Denver, are as large as 150,000 square feet.
