An RMI analysis evaluates the viability of residential clean technologies—electric vehicles (EVs), air-source heat pumps (ASHPs), and rooftop solar—in the US following the expiration of federal tax credits under the One Big Beautiful Bill Act of 2025. The report finds that these technologies still provide significant greenhouse gas (GHG) emissions reductions and household cost savings, though the most effective technology varies by region and household archetype.

This guide provides State Energy Offices (SEOs) with a framework for designing and implementing residential energy rebate programs authorized by the Inflation Reduction Act (IRA). It emphasizes data-driven design, strategic outreach to underserved communities, and the creation of support systems like 'one-stop-shops' to ensure that energy efficiency and electrification retrofits are economically beneficial and accessible, particularly for low-to-moderate income (LMI) households.

A guide by RMI providing a five-step framework for homeowners to decarbonize and electrify their residences, emphasizing energy efficiency, the use of heat pumps and induction stoves, and the utilization of incentives from the Inflation Reduction Act.

A guide by RMI providing six recommendations for homeowners to improve health, save money, and reduce carbon emissions during COVID-19 shelter-in-place orders, focusing on energy efficiency and electrification.

This case study examines 'Lovins GreenHome 1.0', a residence and headquarters for the Rocky Mountain Institute (RMI) completed in 1984 in Snowmass, Colorado. The home serves as a demonstration of 'Factor Ten Engineering' (10xE), an integrative design approach that prioritizes functional goals and passive systems over conventional HVAC installations to achieve radical resource efficiency.

This briefing from the Rocky Mountain Institute (RMI) provides guidance on improving home lighting energy efficiency. It advocates for a 'whole-system' approach—combining efficient bulbs like Compact Fluorescent Lamps (CFLs) and LEDs with dedicated fixtures, lighting controls, and daylighting strategies—to reduce electricity costs and improve lighting quality.

This 2004 guide by the Rocky Mountain Institute (RMI) provides homeowners with strategies to reduce space cooling costs and energy use. It advocates for a hierarchical approach: first minimizing heat gain through passive measures, then utilizing low-energy ventilation, and finally selecting the most efficient mechanical cooling systems based on climate and budget.

This 2004 guide by RMI provides homeowners with strategies to reduce water heating costs and energy consumption through the use of efficient fixtures, maintenance of existing heaters, and the adoption of advanced heating technologies such as solar thermal, heat pumps, and drain-water heat recovery.

This fact sheet outlines greenhouse gas (GHG) mitigation options for the residential, commercial, and agriculture (RCA) sectors in Pakistan. It identifies 12 potential options to improve energy efficiency, with a focus on replacing inefficient appliances and irrigation systems to reduce a projected rise in emissions from 29 MtCO2e in 2012 to 61 MtCO2e by 2030.

This case study describes the City of Holland, Michigan's Community Energy Plan and the subsequent creation of the Holland On-Bill Loan Program, a financing mechanism designed to increase energy efficiency in residential buildings.

The Help My House (HMH) Loan Pilot Program tested the use of on-bill financing (OBF) to implement energy efficiency measures in 125 homes served by South Carolina's electric cooperatives. The program demonstrated that OBF can significantly reduce residential electricity use and costs while maintaining high member satisfaction, serving as a cost-effective alternative to new power generation investment.

This policy brief examines the transition from natural gas to electricity in Colombia's residential sector. Using a simulation model, it finds that while gas currently dominates cooking and heating, a shift toward electrification is necessary due to declining reserves. The report highlights that total electrification is more cost-effective than a mixed transition, potentially saving up to 20 trillion pesos, and significantly reducing CO2 emissions. However, adoption is hindered by high initial equipment costs and cultural inertia, suggesting a need for public policies such as equipment substitution programs and local value chain strengthening.

This working paper analyzes the experiences of residential consumers installing rooftop solar photovoltaic (PV) systems across five Indian cities, identifying key information, financial, and institutional barriers that hinder the adoption of solar energy in the residential sector.
