The Alternate Energy Revolving Loan Program (AERLP), administered by the Iowa Energy Center, provides low-interest loans to individuals and organizations that seek to build renewable energy production facilities in Iowa.

Successful applicants receive a low-interest loan that consists of a combination of AERLP and lender-provided funds. The AERLP provides 50% of the total loan at 0% interest rate up to a maximum of $1,000,000. The remainder of the loan is provided by a lender at market rate.

Eligible Technologies

Eligible renewable energy technologies include solar, biomass, wind and small hydro.

*Note: The State Energy Loan Program is currently closed, but anticipated to reopen in Summer 2025.

The Idaho Governor's Office of Energy and Mineral Resources (OEMR) State Energy Loan Program offers low-interest loans to fund energy efficiency projects for single-family homes in Idaho. Qualified projects include insulation, lighting upgrades, windows, weatherization, HVAC, appliances, and renewable energy. See qualifying addendums on the State Energy Loan Program website for project and equipment requirements.

All loans are evaluated by a financial institution for credit worthiness and must be secured with real estate. Consumers may choose to leverage these loans by accessing utility incentives

The Value-Added Stock Loan Participation Program was created in 1994 and is designed to help farmers finance the purchase of stock in certain types of cooperative, limited liability company, or limited liability partnership that will produce a "value-added agricultural product." This may include wind energy and anaerobic-digestion cooperatives if they meet the eligibility requirements (see Statute and Rules for details).

Like Minnesota's Agricultural Improvement Loan Program, this is a "participation loan" program, where loans are made by individual financial institutions working with the Rural Finance Authority (RFA). The RFA purchases up to 45% of the loan principal up to $40,000. The

The City of San Diego’s Sustainable Building Policy is directed by Council Policy 900-14. The policy contains regulations regarding building measures, private-sector incentives, health and resource conservation, outreach and education, and implementation.

Among the directives is a commitment City-owned, occupied or leased new construction and major renovation projects must meet LEED "Silver" Level Certification. In addition to achieving LEED Certification, Council Policy 900-14 states that City-owned and occupied new construction and major renovation projects of buildings containing more than 1,000 square feet of conditioned space must meet the energy efficiency requirements of San Diego Council Policy 900-03, Zero

Established in 1998 and subsequently revised several times, Connecticut's renewables portfolio standard (RPS) requires each electric supplier and each electric distribution company wholesale supplier to obtain at least 24% of its retail load by using renewable energy by January 1, 2020. The RPS also requires each electric supplier and each electric distribution company wholesale supplier to obtain at least 4% of its retail load by using combined heat and power (CHP) systems and energy efficiency by 2010. In 2018, Public Act No. 18-50 extended the renewable portfolio standard to year 2030, demanding at least 40% Class I renewable energy resources

Section 487 of the New York State Real Property Tax Law provides a 15-year real property tax exemption for solar, wind energy, and farm-waste energy systems constructed in New York State. As currently effective, the law is a local option exemption, meaning that local governments are permitted to decide whether or not to allow it. The exemption was mandatory prior to a 1990 reenactment in which the local option clause was added. The exemption is valid unless a government opts out of the exemption, as opposed to the more common practice of requiring governments to "opt-in" in order to offer

Note: In addition to its RPS, Wisconsin has a clean energy goal of having 100% of its electricity come from carbon-free sources by 2050. This is an executive action rather than a legislatively-set requirement. Further information is available here.

In October 1999, Wisconsin enacted Act 9, becoming the first state to enact a renewable portfolio standard (RPS) without having restructured its electric utility industry. The RPS sets a total goal of 10% of all electric energy consumed in the state coming from renewable energy sources, with different percentage requirements for each electric provider (investor-owned utilities, municipal utilities, and electric

The SunWatts Program offers home and business owners incentives for purchasing solar water heating systems. SSVEC will pay an incentive of 50 cents for every kilowatt-hour saved over traditional water heating in the unit's first year of operation based on the OG-300 rating. Systems must meet all program requirements. See the website above for complete details. 

Under Iowa's methane gas conversion property tax exemption, real and personal property used to decompose waste and convert the waste to gas, collect the methane or other gases, convert the gas to energy, or collect waste for these purposes is exempt from property tax. This section was formerly written to only apply to facilities operated in connection with or in conjunction with a publicly-owned sanitary landfill. 

For facilities that are not connected with or in conjunction with a publicly-owned sanitary landfill, the exemption may only be claimed if the facility is placed in service between January 1, 2008, and December
