On August 8th, 2022, Mayor Lightfoot announced an agreement to purchase 100% clean, renewable energy starting in 2025. They also have implemented the Chicago Climate Action Plan with the goal of reducing greenhouse gas emissions.

History

In June 2001, the City of Chicago signed an agreement with Commonwealth Edison and the Environmental Resources Trust to purchase 20% of its electricity from clean, renewable resources by the end of 2005. Chicago reached this goal in 2008 with a purchase of 215 million kWh of wind and biomass energy from MidAmerican Energy.  The city's plan is to maintain that 20% level for the

As of October 1, 2014, the City of Boulder has 2,084 kilowatts of solar photovoltaics (PV) installed at city facilities with an additional 1 megawatt (MW) being developed. In addition to the PV, each of the three city-owned recreation center pools is partially heated with solar thermal systems generating 32,000 therms annually.

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
