While it's not surprising that US indoor cannabis growing uses a lot of electricity, 1% of all US electric demand, it's sad that so much growing must be done indoors at all. If cannabis were legal, most of these grows could be done outdoors, saving enormous amounts of energy. This article points out how big the carbon footprint of US grown marijuana actually is, costing growers up to $5 billion a year. http://www.huffingtonpost.com/2011/...on-carbon-footprint-environment_n_848865.html
i agree its sad however in canada growing cnbs without lights is next to impossible northern countries would have to import the transportation would create a footprint
Agreed! On the contrary ... I do believe that : "The Marijuana industry needs to be ECO conscious and get GREENER"
One could build an argument using the idea that we need to legalize in order to reduce the carbon foot print. When its legalized there will be advancements in the grow equipment that will be energy saving.
....Solar powered hydro, with the aid of skylighting to cut back the need for light on most days, anyone?
