The lights, fans, air conditioners, etc. required to grow pot indoors apparently draw a ton of electricity.
Evan Mills, a staff scientist at the Lawrence Berkeley National Laboratory, University of California tried — on his own time — to analyze indoor pot’s carbon footprint in a report he released April 5 on his website. He basically looked at the energy required to run all the equipment used in an average indoor operation and crunched those numbers with some out-of-date figures on how much indoor pot plants are being cultivated.
According to Mills, marijuana production’s energy use adds up to:
– The electricity use of 1 million average California homes.
– Greenhouse-gas emissions equal to those from 1 million average cars.
– Energy expenditures of $3 billion per year.
He estimated (in his report, which, again, can be found here) that:
In California, the top-producing state, indoor cultivation is responsible for about 3% of all electricity use or 8% of household use…
Here’s what I want to know, growers: How much does it cost?
Between $50 and $150 per pound for a 25-square-foot indoor pot plot, according to the RAND Corporation’s estimate (in a July 2010 report (found here).
So where’s the green green movement?
