This is a hub for collected links to more information on rebates and freebes from EBMUD, rebates from PG&E, tax incentives from the federal government for insulation, energy efficient windows, efficient furnaces and more, cheap loans from the City of Berkeley to install solar panels and solar hot water. Its smart to install energy saving appliances and water saving plumbing fixtures. The price of gas, electricity, and water is generally on an upward trend...and there are lots of other reasons to conserve. But these energy star appliances and high efficiency toilets are generally more expensive than more standard models. For this reason the government and public utilities offer incentives and assistance for further encouragement.

Please feel free to add other links in the comment section If I've missed any.

This program is designed to encourage people to buy a new refrigerator and not to keep the old one in the garage or basement to store extra beer, roadkill deer for the winter, frozen pizza for emergency dinners etc. PG&E specifically targets refrigerators because there have been a lot of improvements in the efficiency of this specific appliance. In addition, refrigerators are large and hard to get rid of. You need a truck and you have to pay extra at the dump to get rid of the toxic materials. Instead, PG&E will pay you and send a couple of nice men to your house to load it up and haul it away to be recycled and responsibly disposed of.
