If you have old windows or poor insulation, the program, called energy upgrade California offers rebates from 1,000 to 4,000 dollars for projects that make your home more efficient.
Colin Clark from Ecology Action a non-profit helping to run the program explains how it works
CLARK: A contractor comes out and comes to your home and does a very specific to your home analysis of what your home needs. Is it windows, a new HVAC system is it more insulation.
Energy Upgrade is also using federal stimulus money to fund 3% loans fifteen year loans which are being offered to qualified homeowners. Once you have completed the work.
CLARK: You do a test out on the back end and the utility writes you a check depending on how much energy you have saved.
The rebates are being offered indefinitely, but the stimulus money which is being used for overall marketing and the loan program ends in March of 2012.
