I find that so many "green" things are really just marketing ploys.

They are a net loss, not a net gain for the planet.

If people really wanted to help the planet, it comes form little stupid shit like building an aluminum can passive solar heater. Or trading out your big box computer for a little Gigabyte BRIX (going from several hundred watts down to 35)

What is the most interesting power savings in america has been going from great big tube televisions to LED/LCD flat screens tell-a-visions.

BTW: the computer is just acting as a heater. So, if you need the heat, running the computer is just as efficient a heater as any other electric heater.
