Note: As of September 2015, Aspen obtains 100% of its electricity from renewable sources (46% hydroelectric, 53% wind, 1% landfill gas).

In 2005, the City of Aspen set a renewable portfolio goal that has since been increased to 100% renewable energy by 2015. In 2013, 75% of Aspen’s electricity was generated using renewable resources, predominantly hydro and wind.

Approximately 27% of the electricity used by the City of Aspen comes from wind turbines located in Kimball, Nebraska. An additional 45% of the City's electricity comes from hydroelectric plants.  

Electric Program Investment Charge Program 

California's 1996 electric industry restructuring legislation (AB 1890) directed the state’s three major investor-owned utilities (Southern California Edison, Pacific Gas and Electric Company, and San Diego Gas & Electric) to collect a "public goods charge" (PGC) on ratepayer electricity use from 1998 through 2001 to create public benefits funds for renewable energy, energy efficiency, and research, development & demonstration (RD&D). 

California's public benefits fund, the Electric Program Investment Charge Program (EPIC), was established in 2011 to help meet the state's climate goals by decarbonizing the electricity sector. The program invests more than $130

Although the State of Wisconsin does not have any specific laws for contractors dealing with renewable energy, the City of Madison has issued rules for contractor licensing and equipment standards for solar thermal installations. In the City’s Heating, Ventilating and Air Conditioning Code is a requirement for a Class A-4 license for "a person desiring to enter into the business of installing, altering or repairing active solar heating equipment" as well as fee and examination details. As a result of a 2008 amendment (Ordinance No. 08-00122), the A-4 certification is not required if the contractor is certified as a solar

Note: Guam has also adopted a tropical energy code.

The Guam Energy Code, which became effective in October of 2000, requires that piping stub outs be provided for water heaters installed in low-rise residential buildings to enable the future installation of solar collectors.

The JEA Solar Incentive Program provides rebates to JEA's residential customers who install new and retrofit solar hot water heaters on their homes. The rebate is worth $400 for new solar thermal systems installed by an approved contractor.

The incentive applies to the installation of solar water heating systems. Pool heating systems and photovoltaic (PV) systems are not eligible for the rebate. If other incentives (rebates, grants, etc.) are used to fund a solar hot water system, total funding, including JEA funding, cannot exceed the cost of the system.

The Town of Chapel Hill’s energy-conservation ordinance requires all new or expanded buildings constructed by and for the town to achieve a Silver level certification in the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) and be designed to meet the applicable Architecture 2030 fossil fuel energy reduction target from the 2030 Challenge, unless the council grants a waiver. Renovated buildings with additions of five thousand (5,000) square feet of gross occupied area must also be designed to achieve no less than half of the applicable Architecture 2030 fossil fuel reduction target from The 2030 Challenge

Holy Cross Energy's WE CARE (With Efficiency, Conservation And Renewable Energy) Program offers an incentive for customers who install renewable energy generation for net metering at their premises. Eligible renewable energy technologies include wind, hydroelectric, photovoltaic, biomass, and geothermal sources.

Incentive

The incentive offered varies by the size of the renewable energy system as follows:

• $250 per kW for the first 6 kW of a system, and
• $100 per kW for the next 19 kW of a system.

For example, a 15 kW system is eligible for a $2,400 (= ($250 * 6 kW) + ($100 * 9 kW)) incentive

Nevada law requires that solar energy system installers be licensed by the Nevada State Contractors Board. Contractors may be licensed under License Classification C-37 (solar contracting for solar water heating and space heating and air conditioning). Contractors may also perform solar work under License Classification C-1* (plumbing and heating), sub-classification (d) for solar water heating installations, or sub-classification (f) for solar air heating. Contractors may also perform solar work under License C-2 (electrical contracting), sub-classification (g) for photovoltaics used to generate electricity; or C-21 (Refrigeration and air-conditioning), sub-classification (e) for solar air conditioning. Work on utility scale solar projects must

Note: H.B. 576 of 2021 repealed this RPS. The information below is presented for informational purposes only. 

Montana’s renewable portfolio standard (RPS), enacted in April 2005 as part of the Montana Renewable Power Production and Rural Economic Development Act, requires public utilities and competitive electricity suppliers serving 50 or more customers to obtain a percentage of their retail electricity sales from eligible renewable resources according to the following schedule:

• 5% for compliance years 2008-2009 (1/1/2008 - 12/31/2009)
• 10% for compliance years 2010-2014 (1/1/2010 - 12/31/2014)
• 15% for compliance year 2015 (1/1/2015 - 12/31/2015) and for each year thereafter

Public utilities

Hawaii offers several specialty licenses for solar contractors through Hawaii’s Department of Commerce and Consumer Affairs. The following specialty licenses are available: Solar Power Systems Contractor (C-60); Solar Energy Systems Contractor (C-61); Solar Hot Water Systems Contractor (C-61a); and Solar Heating and Cooling Systems Contractor (C-61b). These licenses require business and trade exams plus four years of experience. An Electrical Contractor (C-13) license is required to install photovoltaic systems other than low voltage DC wiring and it includes the work of the C-60 solar power systems contractor. Plumbing contractors (C-37) are also allowed to install solar hot water heating systems.
