It is energy conservation panic time

1. Stop excess heat from entering your home. A titanium oxide layer is like a mirror that reflects both ways. It blocks excess heat from the outside in summer, and it reflects back in heat during the winter.
I applied this to my roof 4 years ago, and it is just amazing. The ceiling is cool to the touch in the afternoon in August! And it saved about 10,000 dollars in reroofing costs.

2. Get a solar water heater. You can probably get a tax refund. It will increase the value of your house on resale, so it will be free. It is ridiculous to burn fossil fuels to make hot water unless you live where it is really cloudy all the time. We have had one of these for 30 years, and it still works fine. I would have had to earn an additional 50,000 dollars to pay for energy to heat our hot water if we hadn't installed it.




3. Solar panels to produce electricity are going to drop in price substantially, so I would wait a few more years to do that. The above 1 and 2 are MUCH cheaper and more urgent. They are low-tech solutions that work now.
