Because many people do have free or next to free power, and most people aren't looking for a 50 day ROI.
I've been wondering about free or low cost power. I've been to trying research and figure out how to find exactly that for a few weeks now, but to no avail. No one I know has unlimited power included in their homeowners or something similar.
I'd love to hear some solid advice on how to join these many people with an edge on power costs.
Thanks.
Europe requires a hell of a lot of heating, which is elec/gas that would have otherwise been burnt for free.
