Cities have long offered programs to homes for reducing energy use. But Private buildings are also a major energy drain.
"The city of Portland's new Clean Energy Works pilot program aims to spur energy-efficiency upgrades at thousands of homes, financed by 20-year loans repaid on monthly utility bills.
But homes only account for about half the energy consumed by buildings in the country. Office, retail and industrial buildings account for the other half, and some experts believe they provide even more potential to save energy and create green jobs."
