There are a number of financial assistance options available to you from local energy providers and the State of California. Options range from rebates on efficient appliances to incentives for participating in events, or more holistic approaches to energy efficiency, like the Home Upgrade program. Contact your energy provider to see what's best for your home.
Work with a specially trained participating contractor (or rater) or a home upgrade advisor to review possible that meet your energy and comfort needs. You must choose a minimum of three measures to qualify to receive up to $3000 in rebates.
For the Advanced Home Upgrade option, rebates are calculated based on the energy saved by your upgrade. Rebates start at $550 and may exceed $5,500*.
Also take the "My Energy Survey" from SDG&E to set goals and a loading order for improvements.
