I fully support this idea. I also own a large number of shares in a carbon nanotube company, which is entirely coincidental.
Rooftop solar panels are pretty commonplace here. My electricity provider will install a
1.5kw grid-connected system for $3000, but I don't know a lot about these systems or how the money would work out. Apparently this system with the typical sunlight in my area will generate 2165kw hours / year, while the average household use in Australia is 6570kwh / year, so I suppose it's trimming a third off the average household electricity bill.
Rooftop solar water heaters are also very common. I would imagine that an electric hot water tank is a bit of an energy hog.
