Well Al Gore is finally putting his money where his mouth is and dropping a lot of money down for energy improvements to his home. The former vice president has installed solar panels, a rainwater-collection system and a geothermal pump. He also replaced all incandescent lights with compact fluorescent or light-emitting diode bulbs -- even on his Christmas tree.

I was looking for the numbers to see how long the pay back is on these improvements, but could only find something about the geothermal heating.

This Old House uses the following numbers for the geothermal heating:
Installation cost: $15,000-$20,000
Savings to heating/cooling bills: 30 to 70%
Break-even point: Seven to eight years
