Residential Renewable Energy Tax Credit

Note: The Taxpayer Certainty and Disaster Tax Relief Act of 2020, signed in December 2020, extended the phase out of this tax credit.

A taxpayer may claim a credit for a system that serves a dwelling unit located in the United States that is owned and used as a residence by the taxpayer. Expenditures with respect to the equipment are treated as made when the installation is completed. If the installation is at a new home, the "placed in service" date is the date of occupancy by the homeowner. Expenditures include labor costs for on-site preparation, assembly or original

Energy-Efficient Mortgages

Homeowners can take advantage of energy efficient mortgages (EEM) to either finance energy efficiency improvements to existing homes, including renewable energy technologies, or to increase their home buying power with the purchase of a new energy efficient home. The U.S. federal government supports these loans by insuring them through Federal Housing Authority (FHA) or Veterans Affairs (VA) programs. This allows borrowers who might otherwise be denied loans to pursue energy efficiency, and it secures lenders against loan default.

FHA Energy Efficient Mortgages
The FHA allows lenders to add up to 100% of energy efficiency improvements to an existing mortgage loan

Community Solar Gardens

H.B. 1342 of 2010 authorized the development of community solar gardens (CSGs) in the service territory of investor-owned utilities in Colorado. H.B. 1003, enacted in 2019 increased the maximum size of a CSG from 2 megawatts to 5 megawatts, and allowed the Public Utilities Commission (PUC) to increase the maximum size to 10 megawatts beginning July 1, 2023. The legislation also removed the requirement that a CSG subscriber's identified physical location be in the same or adjacent county as the CSG, though both locations must be within the service territory of the same investor-owned utility.

Renewable Portfolio Standard

In April 2020, Virginia's legislature passed H.B. 1526, which requires, among other things, the development of renewable portfolio standards for electric utilities and suppliers.

Solar Rights

Wyoming’s Solar Rights Act (1981), states that the “beneficial use of solar energy is a property right”. Solar rights -- a landowner's right against interference with sunlight for the purposes of solar energy -- are thus property rights. 

The Act states that these rights are only valid from 9:00 a.m. to 3:00 p.m. Mountain Standard Time. Outside of these hours, the solar right may be infringed without compensation to the owner of the solar collector. The Act delegates responsibility of enforcement to local governments by requiring local governments to establish a permit system for the use of solar energy. A
