In the aftermath of a May 2007 tornado that destroyed 95% of the city, the Greensburg City Council passed an ordinance requiring that all newly constructed or renovated municipally-owned facilities larger than 4,000 square feet be designed to conform to the platinum rating of the US Green Building Council's (USGBC) LEED Green Building Rating System. The ordinance further requires that such buildings be designed to achieve all 10 points possible under EA Credit 1 "Optimize Energy Performance." Achieving this requires a whole building energy consumption reduction of 42% compared to the standard building baseline (ASHRAE Standard 90.1-2004). 

As of 2014

In January 2008, Currituck County adopted an ordinance to regulate the use of wind-energy systems. The ordinance directs any individual or organization wishing to install a wind-energy system to obtain a zoning permit from the county planning board. Small-scale systems require only administrative approval for the permit, while large systems and utility-scale projects require approval from the board of commissioners.

For the purposes of this ordinance, a wind-energy system is classified as "small" if it has a single turbine with a rated capacity of 25 kilowatts (kW) or less; as "large" if it consists of one or more turbines with

In 2004, Guam enacted legislation (Public Law 27-132) requiring the Guam Power Authority (GPA) to allow net metering for customers with fuel cells, microturbines, wind energy, biomass, hydroelectric, solar energy or hybrid systems of these renewable energy technologies. In 2010, Guam amended net metering  (Public Law 30-141) and raised the system capacity limits to 25 kilowatts (kW) for residential systems and 100 kW for non-residential systems. In February 2024, the non-residential cap was expanded to 500 kW by Public Law 37-71. However, non-residential systems in excess of 250 kW must be paired

The City of Tallahassee Utilities offers a $450 rebate to homeowners* and homebuilders who install a solar water-heating system.

The homeowner must allow the City of Tallahassee to conduct an energy audit on the home in order to make a preliminary assessment of sun exposure and to provide program guidance. All solar water heating equipment

Puerto Rico enacted net-metering legislation in August 2007, allowing customers of Puerto Rico Electric Power Authority, now LUMA, to use electricity generated by solar, wind or "other" renewable-energy resources to offset their electricity usage.

The Puerto Rico Energy Public Policy Act of 2019 guaranteed availability of net metering for 5 years, and calls for a review of the program to be conducted by April 2024. Amendments to the Act by Ley 10-2024 delayed the review to 2030 and guaranteed net metering through the entire period.
