Eine neue Studie hat den Carbon Footprint von Homegrown Marijuana untersucht und das Ergebnis ist für Hippies dann doch eher ernüchternd, um's mal diplomatisch zu formulieren.
The analysis performed in this study finds that indoor Cannabis production results in energy expenditures of $5 billion each year, with electricity use equivalent to that of 2 million average U.S. homes. This corresponds to 1% of national electricity consumption or 2% of that in households. The yearly greenhouse-gas pollution (carbon dioxide, CO2 ) from the electricity plus associated transportation fuels equals that of 3 million cars. Energy costs constitute a quarter of wholesale value.
