Green Mountain Power, an investor-owned electric utility operating in Vermont, offers a credit to customers with net-metered photovoltaic (PV) systems. In addition to the benefits of net metering, Green Mountain Power customers with a PV system less than 15 kilowatts (kW) receive a credit of $0.053 per kilowatt-hour (kWh) of electricity generated by the system. PV installations larger than 15 kW receive a credit of $0.043 per kWh. This credit is available to all customers of Green Mountain Power. The incentive does not have a specified duration or expiration date.

In order to net meter, customers must first apply for

In January 2008, New Jersey enacted legislation mandating the use of high performance green building standards in new state construction. The standard requires that new buildings larger than 15,000 square feet constructed for the sole use of state entities should be designed and managed to meet high performance green building standards. The law allows for exceptions from specific requirements in cases of practical difficulty. These exceptions only apply to the specific requirement in question and do not extend to all requirements. With some exceptions the state is also required to purchase Energy Star products when available, a provision adopted in

In March 2008, South Dakota enacted legislation mandating the use of high-performance building standards in new state construction and renovations. The law was updated in 2021, lessening the previous standards and removing the requirements for renovations. The policy now requires that new state buildings achieve the U.S. Green Building Council's LEED certified rating (decreased from silver rating), a two-globe rating under the Green Building Initiative's (GBI) Green Globe rating system, or a comparable numeric rating from another accredited sustainable building certification program. The law applies to all new construction projects by state agencies, departments, or institutions that has a cost

In January 2007, the City of Plano adopted a policy to "finance, plan, design, construct, manage, renovate, and maintain its facilities and buildings to be sustainable." This policy applies to new construction and major renovations. Return on investment will be considered when determining feasibility of implementing green features. 

Design elements will be prioritized based on their ability to provide future energy savings, water conservation, waste reduction, and improved indoor air quality. Key factors to consider incorporating into the design include:
1. Use of passive solar energy
2. Natural lighting (day lighting) and adjustable lighting systems
3. Highly reflective roof and

Clean Energy Standard (CES) and CES-E: The CES sets a minimum percentage of electricity sales that retail electricity suppliers must procure from new clean energy sources beyond the RPS requirements. The CES began in 2018 at 16% and increases 2% annually to 80% in 2050. The CES-E applies to clean generating resources that pre-existed the RPS and is 20% for 2021.

Solar Carve-Out (SCO) & Solar Massachusetts Renewable Target (SMART):  As part of the RPS, the SCO program, initiated in 2010 and expanded in 2014, requires electricity suppliers to meet a portion of the RPS obligation through solar energy

HB 2261, enacted in July 2008,  created a loan program for agriculture and aquaculture renewable energy projects. Farmers and aquaculturists may receive loans for projects involving photovoltaic (PV) energy, hydroelectric power, wind power generation, methane generation, bio-diesel and ethanol production. Loans may provide up to 85% of the project cost (up to a maximum of $1,500,000) for a term of up to forty years. To be eligible, the applicant must be a qualified farmer or aquaculturist with a sound credit rating and the ability to repay the loan, as determined by the Department of Agriculture.

These renewable energy loans fall

Alaska Housing Finance Corporation (AHFC) offers loans of up to $30,000, with a repayment term of 15 years, to qualified borrowers through the Second Mortgage for Energy Conservation program. Borrowers apply to AHFC for financing to make energy improvements on owner-occupied properties. Applicants must select from the list of energy upgrades, which are provided by an AKWarm certified energy rater. All improvements must be completed within 365 days of loan closing. Improvements not listed or recommended by the rater may not be included in the loan. The interest rate is the Taxable Program or Rural Owner-Occupied 15-year interest rate

Note: The Home Energy Rebate Program is suspended effective 5 pm March 25, 2016. Applicants on the waitlist may check the status of their application online, and new participants may call 1-877-257-3228 up until the close of business on March 25 to enroll.

Under the Home Energy Rebate Program, homeowners who want to make their own energy efficiency improvements on their home can receive a rebate for some of their expenditures. The program requires a home energy rater to evaluate homes before and after the improvements. Rebates are dependent on the relative amount of efficiency gained and the actual cost

Note: Energy efficiency program appointments and rebates are on a first-come, first-served basis and are for a limited time only. Once a program reaches its maximum capacity for the year, the program will resume the next calendar year. 

PNM offers several types of incentives for residential customers to improve the energy efficiency of eligible homes. Rebates are available for appliances and cooling equipment.

PNM also offers the PNM Home Energy Checkup, which gives residential customers a snapshot of their home's electricity use and identifies opportunities to reduce electricity waste. The fee for any Home Energy Checkup package is waived for

In June 2008, Hawaii enacted legislation, SB 644, with the intent to require solar water-heating (SWH) systems to be installed on all single-family new home construction, with a few exceptions. This legislation had several errors that were corrected by legislation passed during the 2009 legislative session. In June 2009, HB 1464 was signed by the governor and addressed the errors in the previous solar water heating requirement.

As of January 1, 2010, building permits may not be issued for new single-family homes that do not include a SWH system. The state energy resources coordinator may provide a variance for
