Rebates

In 2008 Prince George's County enacted legislation offering a property tax credit on residential structures equipped with solar and geothermal systems. As originally devised, the credit could only be taken for systems used to heat and cool a structure or provide hot water for a structure. However, in April 2009 the county enacted additional legislation (Council Bill 05-2009) extending the property tax credit to solar-electric (PV) systems, effective May 22, 2009. Prince George's County also later extended property tax credit to include leases and solar power purchase agreements. 

The tax credit for solar or geothermal systems is equal to 50%

In October 2008, New Jersey enacted legislation exempting renewable energy systems used to meet on-site electricity, heating, cooling, or general energy needs from local property taxes. (There is not a state component to property taxes in New Jersey). Eligible renewable energy systems* include solar PV, wind, fuel cells, sustainable biomass, geothermal electric, landfill gas, hydroelectric, resource recovery, wave, and tidal systems that produce electricity. Systems that produce energy from solar thermal energy (e.g., solar hot water) or geothermal energy (e.g., geothermal heat pumps) are also eligible for the exemption. The exemption may be claimed for all qualified systems installed on

The original enabling legislation in 2008 ended the program after five years. In 2012, H.B. 250 extended the program an additional 10 years through June 2023. In 2023, H.B. 62 extended the life of this program in perpetuity, removing the sunset date of June 2023.

In 2024, S.B. 187 approved $10.5 million for five projects under Round 16 (FY 2025). Through FY 2025, the legislature has authorized over $328 million in grants across 924 grants.

In May 2008, Alaska enacted legislation authorizing the creation of the Alaska Renewable Energy Fund, a grant fund administered by the Alaska Energy Authority (AEA)

Governed by a nine-member board of trustees elected by the membership, the co-op holds an annual meeting each year, with the 2025 gathering held on March 29 in Keystone Heights. Clay Electric offers Energy Conservation Loans of up to $10,000 to help members finance energy efficiency improvements such as high-efficiency heat pumps, insulation, solar water

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.

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

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.

In May 2013, Oklahoma enacted H.B. 1990, repealing the high-performance building certification program.

The State is still required by statute to adopt planning and construction standards for state buildings that conserve energy and optimize the energy performance of new buildings. The standards must reduce dependence on imported sources of energy through energy efficiency and local and renewable energy sources.

The standards must also authorize the Office of Management and Enterprise Services to pursue ENERGY STAR designation to demonstrate energy efficiency in public buildings. 

Note: As of July 2023, Missouri state facilities under construction or renovation, and commercial buildings purchased or leased by state agencies, must comply with the 2015 IECC, pursuant to the Section 8.812 requirement that standards be at least as stringent as the latest version of the IECC.

Energy Conservation Goals

In April 2009 Missouri’s Governor issued Executive Order No. 09-18, requiring all state agencies whose building management falls under the Office of Administration to adopt policies designed to reduce energy consumption by 2% each year for the next 10 years.
