The Texas property tax code allows an exemption of the amount of 100% of the appraised property value increase arising from the installation or construction of a solar or wind-powered energy device that is primarily for the production and distribution of thermal, mechanical, or electrical energy for on-site use and devices used to store that energy.

Under H.B. 2500 (2013), solar energy devices installed or constructed on or after January 1, 2014, used for a commercial purpose are subject to the cost method of appraisal, and the depreciated value must be calculated using a useful life of 10 years

Oregon law states that any change in real market value to property due to the installation of a qualifying renewable energy system is exempt from assessment of the property’s value for property tax purposes. Qualifying renewables include solar, geothermal, wind, water, fuel cell or methane gas systems used to heat, cool or generate electricity. This exemption is intended for end users and only applies to systems that are net metered or primarily intended to offset on-site electricity use.  Systems installed on real property that

Although Pennsylvania's December 1996 electricity restructuring law did not establish a clean-energy fund, four renewable and sustainable-energy funding programs were subsequently created through individual settlements with the state’s five major distribution utilities: Metropolitan Edison Company (Met-Ed), Pennsylvania Electric Company (Penelec), PECO Energy (PECO), PP&L (PPL), and Allegheny Power/West Penn Power Company (WPP). These utilities created individual "Sustainable Energy Funds" with the goals of promoting (1) the development and use of renewable energy and advanced clean-energy technologies, (2) energy conservation and efficiency, and (3) sustainable-energy businesses. Each utility has established an oversight board and designated a fund administrator.

The four Sustainable

In 1975, the City of Santa Clara established the nation's first municipal solar utility. Under the Solar Water Heating Program, the Santa Clara Water & Sewer Utilities Department supplies, installs and maintains solar water heating systems for residents and businesses. In addition, the city has also installed solar energy equipment for a number of its own facilities.

Solar equipment is available from the city for heating swimming pools, process water and domestic hot water. The hardware (solar collectors, controls and storage tanks) is owned and maintained by the city under a rental agreement. The renter pays an initial installation fee

Note: According to the 2025 Renewable Energy Plan, in 2024, City of Columbus Utilities purchased or generated 22.82% of its total electric usage through renewable energy sources.
