San Francisco adopted a mandatory green building code for new construction projects in September 2008, establishing strict guidelines for residential and commercial buildings according to the following schedule:

The City of Chamblee, Georgia requires all of its new municipal buildings over 5,000 square feet of occupied space or one million dollars in cost to be certified under LEED (Leadership in Energy and Environmental Design) standards. Buildings under 5,000 square feet or one million dollars may be certified under Energy Star or EarthCraft Light Commercial standards in lieu of LEED. Additionally, other projects may be certified by programs other than LEED if approved by the Planning and Development Director. Renovations must also follow LEED guidelines, or other programs if LEED certification is not feasible.

The City of Chamblee also

In June 2008, the Governor of Indiana issued an Executive Order establishing an energy efficient state buildings initiative. The order requires the Indiana Department of Administration (DOA) to develop design standards for all new state buildings that require a cost-effectiveness analysis of the building with a goal of achieving energy efficiency. These rules apply to all state agencies, departments, boards, offices, commissions, and public universities. 

The DOA has incorporated the requirements of the Executive Order into Indiana's standard instructions to designers for projects on state-owned buildings. Efficiency can be demonstrated through adherence to any of the following standards:

• A rating

Note: As of February 1, 2017, FEUS' net metering program is closed to new customers. Existing customers are grandfathered under the most recent net metering tariffs.

Net metering rules developed by the New Mexico Public Regulation Commission (PRC) apply to the state's investor-owned utilities and electric cooperatives. Municipal utilities, which are not regulated by the commission, are exempt from the PRC rules but authorized to develop their own net metering programs.

Farmington Electric, a municipal utility, offers net metering to residential and commercial customers with systems up to 10 kilowatts (kW) in capacity that were installed by January 31, 2017.

The South Carolina Public Service Commission issued two orders in May 2021 adopting new Solar Choice Tariffs for Duke Energy Progress, Duke Energy Carolinas, and Dominion Energy South Carolina. Customers who installed their systems on or after January 1, 2022 must take service under the Solar Choice Tariffs described below. Customer-generators who applied for net metering prior to January 1, 2022 may remain on a prior tariff for a period of time: December 31, 2025 for customers who applied for net metering before May 16, 2019, and May 31, 2029 for customer-generators who applied for net metering between May 16

The Public Regulation Commission (PRC) adopted revised standards and procedures for the interconnection of generating facilities in New Mexico in July 2008.

Rule 569 applies to all qualifying facilities (QFs) under the federal Public Utility Regulatory Policies Act, which generally includes all renewable energy systems and combined heat and power (CHP) systems up to 80 megawatts (MW) in capacity.

Rule 568 applies to renewable energy systems and CHP systems up to 10 MW in capacity. The purpose of Rule 568 is to simplify the interconnection requirements for QFs up to 10 MW and to encourage the use of small-scale, customer-owned

In August 2008, the State of New York enacted legislation allowing a property tax abatement for photovoltaic (PV) system expenditures made on buildings located in cities with a population of 1 million or more people. This limits the abatement to systems installed within New York City. Eligible buildings include all real property except utility real property. As originally enacted, the in-service deadline for eligible systems was December 31, 2012. However, in August 2012 the abatement was extended to systems placed in service through December 31, 2014, at a reduced rate. In September 2014, S.B. 746 extended the compliance period for

In August 2008, North Carolina enacted legislation that exempts 80% of the appraised value of a "solar energy electric system" (also known as a photovoltaic, or PV, system) from property tax. For the purposes of this assessment, the term "solar energy electric system" means "all equipment used directly and exclusively for the conversion of solar energy to electricity." This incentive is effective for taxable years beginning on or after July 1, 2008.

A Memorandum sent to County Commissioners in February 2011 clarified that residential PV systems that are not used to generate income or in connection with a business may

The New Jersey Office of Clean Energy (OCE) offers rebates to state residents who purchase certain energy efficient home appliances. The program website has a search engine where consumers can look up if their product is eligible for rebate. The OCE also offers a $50 rebate for refrigerator/freezer recycling. This recycling offer is only valid till June 30, 2017.

When mail-in rebates are active, as a general rule, all appliances must be ENERGY STAR rated; however, additional requirements may apply to different types of appliances. Rebate requests must generally be made no later than 180 days after the purchase of a

City of Tallahassee Utilities (CTU) offers residential customers rebates for ENERGY STAR appliances, Efficient HVAC Systems, ENERGY STAR homes, Solar Water Heaters, and Natural Gas Appliances.
