Huge Energy Footprint of The Marijuana Industry

USA -- As legal marijuana markets continue to expand in the United States, some experts are arguing that growers have both the need and the opportunity to make their operations, well, greener. A new report, published by data analysis firm New Frontier, highlights the huge energy footprint of marijuana cultivation and outlines strategies to make production more energy efficient — a transition that the authors claim is not only good for the environment, but good for business, too.“We wanted to focus on this issue of energy use in the marijuana industry because we think it is one that is going to have very significant long-term implications,” said the new report’s lead author John Kagia, director of industry analytics for the firm, which specializes in data and analytics for the cannabis industry. “Marijuana is the most energy-intensive agricultural commodity that we produce, and that’s largely because of the very high energy costs associated with its cultivation and production indoors.”
The new report draws on data from a variety of sources, including businesses within the industry, government agencies and consumer studies, and paints an alarming portrait of the industry’s extreme energy use. Research cited in the report suggests that marijuana production in the U.S. accounts for one percent of the entire nation’s electrical output — the equivalent of the electricity used by 1.7 million homes with a staggering price tag of $6 billion every year.Most of this electricity is used to facilitate indoor cultivation, which is the focus of the new report. Historically, this growing strategy has been a way for growers to cultivate their plants discreetly, the report notes, although it also allows for more precise control over the plants’ environment. The problem is that all the controls required to maintain an indoor growing space can require huge amounts of electricity. In addition to artificial lighting, indoor cultivation also requires dehumidification, ventilation and air conditioning — all energy-intensive processes.The report’s focus highlights a problem that deserves greater attention, according to Evan Mills, an energy efficiency consultant and staff scientist at the Lawrence Berkeley National Laboratory. Mills served as an adviser to the new report and his independent research on the carbon footprint of cannabis production (not associated with his work at the national laboratory) is extensively cited in the paper. “State governments in California and elsewhere have begun to address the destructive impacts of unregulated outdoor cultivation, but have yet to recognize what may be even greater environmental consequences from the prodigious amounts of energy used by indoor operations,” he said in an email to The Washington Post.While the issue may remain under-addressed in many places, though, it is starting to gain mainstream attention. Last year, for instance, a paper in the Columbia Journal of Environmental Law noted the industry’s high power use and proposed that states in which marijuana use is legalized should also write policies requiring the industry to power itself with clean energy.As an example of indoor cultivation’s intensive energy requirements, the new paper points to a report from utility company Xcel Energy, which claimed that marijuana facilities in Colorado consumed 200 million kilowatt-hours in 2014. Overall, New Frontier’s report estimates that the industry in the state paid an electricity bill of approximately $19.6 million in 2014 — notable, as he pointed out, because there were fewer than 1,200 licensed growers in the state that year.From a financial perspective, Kagia pointed out that the historically high prices growers have charged for their products have enabled them to easily recoup the costs of such high energy use. But he suggested that the industry’s expanding legal market may soon be changing that.“In an increasingly competitive environment, there’s a lot of downward pressure on prices, and we expect that as the environment becomes much more competitive, the ability to maintain the cost structure driven by such high energy use will be unsustainable,” Kagia said. “Currently energy accounts for approximately half of the wholesale prices of marijuana, and as those prices fall, the share of energy and the total production cost will continue to increase.”So there’s an economic imperative to use less energy as well as an environmental one. The question is how it can be done. New Frontier’s report outlines a number of strategies on this front.First, and most obviously, growers could switch to outdoor or greenhouse cultivation when possible. But Kagia pointed out that this isn’t an option for everybody. “There are some environments, by regulation or because of the environmental conditions, you would not be able to,” he said, noting that very cold or very hot climates would prohibit the growing of all but a few strains of marijuana. But in cases where state or municipal laws prohibit outdoor growing, the report suggests that growers begin advocating for less restrictive regulations.However, there are certain other appeals to indoor growing, such as easier pest management, that may deter some growers from moving outdoors, even if the option is available. And it’s also important to note that outdoor cultivation, while certainly less energy-intensive, comes with its own set of environmental concerns. The large amounts of pesticides typically used to protect outdoor marijuana farms is among the biggest of these.Fortunately, it’s possible to make indoor cultivation more energy efficient, the new report says. Installing more energy efficient lighting is one of the biggest steps. According to the report, growers have traditionally tended to rely on high intensity discharge lamps for their lighting. The report lists several more efficient alternatives, including specially designed LED lights and induction lights, which use magnets to transmit electricity.“Over the past decade or so, great strides have been made in the lighting technologies or solutions provided by the LED companies,” Kagia said. “To date, they have still not been able to surpass the cost performance threshold offered by existing lights, but we are getting there, and we think this innovation that is happening around the lighting sector is one of the ways that this industry will be able to decouple itself from this extremely high energy use.”The report also recommends that growers conduct energy audits and install smart meters to keep better track of where they are expending the most energy. And finally, Mills also noted that a major challenge for improving efficiency in the future will be for policymakers to get involved in the issue and “exercise foresight” when developing regulations that will affect the industry’s energy use. Addressing grow facilities in building energy codes, for example, and coming up with carbon-neutral building designs specifically for grow facilities is one forward-thinking goal he suggested.“There is no reason that this industry should be exempt from the kinds of energy efficiency requirements or voluntary energy information and incentive programs that are otherwise so widespread,” he said by email. “Given the construction booms that have followed legalization in some states, it’s incumbent on policymakers to put energy plans in place beforehand.”Chris Mooney contributed to this report.Source: Washington Post (DC)Author: Chelsea Harvey Published: February 18, 2016Copyright: 2016 Washington Post CompanyContact: letters Website: URL:  -- Cannabis Archives

Prohibition is Wasteful
Spot on, Sam Adams. Decades of cannabis prohibition is to blame for high energy costs. Without the distorted effects of prohibition, cannabis would have been bred for various climactic conditions and would mostly be grown under natural sunlight, as the creator intended. Prohibition is wasteful, short-sighted and a crime against nature and humanity.Those responsible for the "war crimes" of prohibition should be in prison, growing under artificial light.

Funny that the comments on this article
Over at the Post's website seem to have turned into a home grow thread.It's a brave new world.Part of it is, anyway.

energy wasted
the article seems vague - so who's fault is it that an entire industry is growing produce under wasteful indoor lighting, while all other produce is grown in California's Central Valley?  of course the Deep State loves burning fossil fuel. The indoor growing is just another benefit of Prohibition to the oil families.

Is there a crime being committed? Call 911!
"There is no reason that this industry should be exempt from the kinds of energy efficiency requirements or voluntary energy information and incentive programs that are otherwise so widespread,” (Kagia said)"Holy High Crimes and Misdemeanors, Batman, they're getting away with . . . something!"

How Ironic
The government insisted my great grandfather pay his taxes on his farm by demanding he contribute a certain amount of Hemp in the 1800's...
My how lies and deception can really change and fool the common man...sigh.
