Wyoming

Wyoming is the nation’s top coal-producing state and the second biggest net energy supplier, after Texas, accounting for around 40% of all coal mined in the country. While just over half of in-state electricity generation comes from coal, renewables account for 36%, largely from wind, which has more than doubled since 2019. The state’s emissions have changed very little from 1990-2022, increasing only 2%.

Progress by Policy Area

Enacted Enacted policies have been passed or established in a state by a governing body via legislation, executive orders, rules, regulations, and/or other program creation, and remain in effect.
In-progress In progress policies have been established in a state, but final regulations, rules, or plans are pending final approval. This also includes legislation and executive orders that require regulations to be put into effect.
Partially Enacted Partially enacted policies have been enacted in the state, but are missing one or more policy components. Dashboard policies cannot be considered partially enacted unless policy components are available.
Not Enacted Not enacted policies have not been passed or established in the state or are no longer in effect.

Glossary of Terms

The colored bars indicate the status for each policy on the Dashboard, viewed across seven policy areas.

Status	Policy	Policy Area	Policy Category	Year Enacted
Not Enacted	Residential Energy Codes Empty column Residential energy codes are statewide building codes that dictate the energy performance requirements of newly constructed residential buildings.	Buildings and Efficiency	Building Codes
Not Enacted	Commercial Energy Codes Empty column Commercial energy codes are statewide building codes that dictate the energy performance requirements of newly constructed commercial buildings.	Buildings and Efficiency	Building Codes
Not Enacted	Stretch Building Energy Codes Empty column Stretch building energy codes are an optional, more stringent building code established by the state that local jurisdictions can adopt to require that newly constructed buildings are more efficient than the baseline state codes.	Buildings and Efficiency	Building Codes
Not Enacted	Appliance Standards Empty column Appliance standards set minimum energy and water conservation requirements for appliances and equipment.	Buildings and Efficiency	Building Standards
Not Enacted	Building Performance Standards Empty column Building performance standards establish energy and/or greenhouse gas performance targets for existing buildings in a state. These targets increase in stringency over time, leading to efficiency improvements in buildings to conserve energy and reduce emissions.	Buildings and Efficiency	Building Standards
Not Enacted	Clean Heat Standards Empty column Clean heat standards establish a performance standard requiring heat providers to deliver a gradually-increasing percentage of low-emission heating services to customers.	Buildings and Efficiency	Building Standards
Not Enacted	Energy Efficiency Resource Standards (EERS) Empty column Energy efficiency resource standards (EERS) establish targets and deadlines for utilities to reduce electricity demand through efficiency or "demand side" programs.	Buildings and Efficiency	Building Efficiency
In-Progress	Property Assessed Clean Energy (PACE) Empty column Wyoming has enacted residential and commercial PACE-enabling legislation, but does not have active programs. Establishing Policies HB 179 (2011)	Buildings and Efficiency	Building Efficiency	2011
Partially Enacted	Weatherization Funding Empty column The State Policy Opportunity Tracker (SPOT) breaks clean energy policies down into “components”, which are binary questions to evaluate policy quality. Higher quality policies have more of their SPOT components fulfilled. Establishing Policies SPOT - Weatherization Funding in Wyoming Policy Components enacted enacted not-enacted not-enacted 2/4	Buildings and Efficiency	Building Efficiency
Not Enacted	All-Electric Buildings Empty column All-electric buildings policies require new buildings to be constructed with all-electric heating, cooling, and cooking systems to transition away from fossil-fuel use in buildings.	Buildings and Efficiency	Building Electrification
Not Enacted	Thermal Energy Networks Empty column Thermal energy networks are neighborhood-scale energy projects that allow multiple buildings to be connected through a shared network of underground pipes to distribute heating and cooling, often using renewable energy sources like geothermal or waste heat. State policymakers can create an enabling regulatory structure, and may also commission pilots, allow cost recovery, or create mandates to help transition from natural gas.	Buildings and Efficiency	Building Electrification
Not Enacted	Eliminating Line Extension Allowances Empty column Gas line extension allowances (LEAs) are policies that enable new customers to connect to the natural gas system, with some or all of the costs paid for by existing gas ratepayers. Eliminating line extension allowances results in new customers directly paying for the costs to install their new gas service.	Buildings and Efficiency	Building Electrification
