Idaho

Idaho has substantial renewable energy resources that dominate in-state electricity generation, much of which is from relatively inexpensive hydropower. However, the state’s net emissions have increased 74% from 1990-2021, largely due to agricultural activity. Natural gas production has significantly increased in recent years, and aside from industry, every sector has increased emissions.

Glossary of Terms

Status	Policy	Policy Area	Policy Category	YR Enacted
Enacted	Commercial Energy Codes Empty column The statewide energy code for commercial building construction is 2018 IECC and ASHRAE 90.1-2016. Establishing Policies Idaho State Energy Code (2020)	Buildings and Efficiency	Building Codes	2020
Enacted	Residential Energy Codes Empty column The statewide energy code for residential construction is 2018 IECC with amendments. Establishing Policies Idaho State Energy Code (2020)	Buildings and Efficiency	Building Codes	2020
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 Idaho has enacted residential PACE-enabling legislation, but does not have an active program. Establishing Policies HB 624 (2024)	Buildings and Efficiency	Building Efficiency	2024
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 Idaho Policy Components not-enacted enacted enacted enacted 3/4	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
