Technology Options for Doubling the Energy Efficiency of Room Air Conditioners

This report explores pathways to double the global rate of energy efficiency improvement, focusing on room air conditioner (AC) technologies that deliver substantial efficiency gains. It analyzes the technical potential of ultra-efficient room ACs in China, showing efficiency could improve by up to 40% within a decade with only a 10% increase in cost. The report also examines market implications and estimates the associated carbon reduction benefits from reduced energy consumption.

Key Findings

  • Room ACs are becoming more efficient thanks to better compressors, inverter technology, larger heat exchangers, and electronic controls. They are also becoming more climate-friendly due to the uptake of low-GWP refrigerants.
  • Efficiency improvements now focus on optimizing the whole system instead of individual parts, using smarter design and controls to reduce energy use.
  • Some technologies are already widely used and can improve efficiency by 15–25%, while newer smart control technologies could deliver up to 40% efficiency gains in the future.
  • Different refrigerants require different design approaches to maximize efficiency and reduce costs.
  • Room AC efficiency is expected to continue improving over the next decade, with the potential to reduce electricity use and cut up to 3.7 gigatons of carbon dioxide emissions.

Recommendations

  • Governments should support high-efficiency air conditioners through incentives, rebates, and policies that encourage climate-friendly refrigerants and smart technologies. This can lower consumers’ energy bills, reduce pressure on power grids, and significantly lower greenhouse gas emissions.
  • Countries should strengthen energy efficiency standards and align them with the best available technologies while keeping products affordable.
  • Governments, industry, and researchers should work together internationally to share knowledge, develop common standards, and speed up the adoption of efficient cooling technologies.

Residential Energy Consumption Patterns and Appliance Ownership in India: Insights From a 2024 Household Survey

India’s energy landscape is rapidly evolving, driven by a growing population, an expanding economy, and growing access to modern energy services.

With a population exceeding 1.4 billion, India’s residential sector is a key contributor to the country’s overall electricity consumption. As of 2024–25, it accounts for ~25% of total electricity usage in the country, with an annual growth rate of 6%.

To better understand the factors driving up this energy use, CLASP conducted a study examining appliance ownership, usage patterns, and their impact on residential electricity demand. The study draws on data collected from a sample of 4,321 households across 20 states, covering both urban and rural areas and representing major climatic zones.

Key findings


  • Energy consumption in surveyed households is not uniform: Climatic conditions, socioeconomic status, awareness of energy efficiency strongly influence appliance use.
  • Among surveyed households, electricity use is primarily driven by thermal comfort, which accounts for 40% of total consumption, reflecting the growing demand for cooling solutions. Kitchen appliances contribute 28% to electricity use, while lighting accounts for 11%, and other miscellaneous uses make up the remaining 21%.

Annual electricity use in surveyed households by end use

  • Affordability is a decisive factor in appliance purchases, often outweighing energy efficiency considerations.
  • Consumer behavior around energy efficiency is inconsistent. All surveyed households reported using LED lighting, however, only 2% actively considered energy efficiency when purchasing lighting solutions. This contrast highlights the importance of initiatives promoting the adoption of energy-efficient technologies.

By identifying the key factors that influence residential energy use, this study aims to inform the development of effective energy efficiency policies and provide policy recommendations for managing growing demand efficiently. By acting on these insights, India can ensure that its residential sector evolves in a sustainable, energy-efficient, and climate-resilient manner.

Solar Appliance Repairability Index Series

Solar appliances often constitute a significant financial investment, especially for those living in off-grid regions where recycling is also limited. Enhancing appliance repairability aims to protect consumer investment and the environment by incentivising designs that are easier to repair or refurbish.

This Solar Appliance Repairability Index Series consists of an introductory paper that outlines the findings of current repair practices and key criteria for assessing repairability, as well as a repair index for solar water pumps, fans, and refrigerators.

The introductory paper, “Closing the Loop: Enhancing Repairability in the Solar Appliance Market,” synthesises field research in Kenya and interviews with 32 stakeholders. Findings reveal that the repair of solar appliances is currently managed in an informal, uncoordinated way. This poses challenges to the sustainability of the solar appliance sector, including:

  • Knowledge gaps
  • Access to repair services
  • Missed job opportunities

The Repairability Index for Solar Fans, Refrigerators, and Water Pumps provides a structured framework to assess how easily an appliance can be repaired across four core parameters:

  • Spare parts and tools
  • Disassembly
  • Skills complexity
  • Documentation

The Repairability Index is intended to serve as a practical decision-making tool for manufacturers, distributors, program implementers, and policymakers.

About Efficiency for Access

Efficiency for Access is a global coalition dedicated to advancing access to energy and affordable, energy-efficient appliances in underserved communities. It is a catalyst for change, accelerating access to off- and weak-grid appliances that boost incomes, avoid carbon emissions, improve quality of life, and support sustainable development. The coalition is co-chaired by UK aid from the UK government via the Transforming Energy Access platform and the IKEA Foundation.

About the MECS programme

Modern Energy Cooking Services (MECS) is an eleven-year research programme funded by UK Aid (FCDO). MECS is a geographically diverse, multicultural, and transdisciplinary team working in close partnership with NGOs, governments, the private sector, academia, research institutes, policy representatives, and communities in 16 countries of interest to accelerate a transition from biomass to genuinely ‘clean’ cooking.

In seeking to spark a new approach to clean cooking, the MECS programme researches the socio-economic realities of a transition from polluting fuels to a range of modern fuels. Whilst the research covers several clean fuels, the evidence is pointing to the viability, cost-effectiveness, and user satisfaction that energy-efficient electric cooking devices provide. Significant progress has been made in access to electricity in the last decade, but these gains are sometimes disconnected from the enduring problem of clean cooking. By integrating modern energy cooking services into the planning for electricity access, quality, reliability and sustainability, MECS hopes to leverage investment in renewable energies (both grid and off-grid) to address the clean cooking challenge.

Pathways to Prevent Dumping of Climate Harming Room Air Conditioners in the Global South

Low-efficiency, climate-harming room air conditioners are common across the Global South. This is due largely to a practice known as environmental dumping, which raises costs for consumers, strains national electric grids, and jeopardizes climate mitigation targets.

What is environmental dumping?

When appliances that don’t meet the regulatory standards of the countries where they are manufactured are export to countries with lower or no standards, this is considered environmental dumping.

Environmental dumping of room air conditioners is a common practice, resulting in high volumes of low-efficiency, high-global-warming potential (GWP) room air conditioners in countries that lack stringent room AC standards and refrigerant regulations.

This occurs across the Global South, as research by CLASP and the Institute for Governance & Sustainable Development (IGSD) with support from the Climate and Clear Air Coalition (CCAC) has revealed. Studies from Africa (2020),  Southeast Asia (2023), and Latin America & the Caribbean (2026) have confirmed that low-efficiency, high-GWP cooling appliances are prevalent in all three regions.

What are the impacts on people & planet?

As temperatures rise around the globe, the demand for cooling appliances is growing rapidly. The number of ACs in use is projected to grow from 1.6 billion units in 2023 to 5.6 billion in 2050, according to the IEA. Despite that, only 15% of the 3.5 billion people living in warm regions have air conditioning. Making cooling more accessible requires overcoming a key barrier: affordability.

The prevalence of low-efficiency room air conditioners in the Global South makes this more difficult to achieve, as these appliances cost consumers more to run.

Low-efficiency, high-GWP room air conditioners also strain electricity systems and lock countries into higher energy use and emissions, slowing progress toward national and global climate goals.

How can environmental dumping be prevented?

Ambitious national appliance efficiency policies are a powerful way to help markets shift toward next-generation technologies that lower electricity costs and cut CO₂ emissions. Complementary government action on obsolete refrigerants can further speed the transition to climate-friendly alternatives.

Still, no single country can tackle environmental dumping or the spread of outdated, high-emission products alone. Addressing these challenges requires shared responsibility and close collaboration among governments, industry, civil society, and international partners.

Doubling Energy Efficiency with Appliances

Appliance efficiency could provide roughly one fifth of the reduction in energy demand needed to meet a pivotal climate commitment, according to CLASP’s analysis “Doubling Energy Efficiency with Appliances: How governments can leverage appliances to reach climate targets.” With nearly 110 countries pledging at COP28 to double annual energy efficiency improvements by 2030, more ambitious appliance policies are critical to reaching this goal before the narrow window for net zero by mid-century closes.

Key Findings

  • To get on track for net zero emissions by mid-century, the average global annual rate of improvement in energy intensity must double to at least 4% by 2030. Appliance efficiency can deliver approximately 20% of the total reduction in energy demand required to meet this goal.
  • Brazil, China, India, and Indonesia have recently taken significant steps to integrate appliance efficiency into their national strategies, recognizing its critical role in achieving energy and climate goals.

Recommendations

  • Policymakers must rapidly implement stringent minimum efficiency standards for appliances, ensuring that they meet or exceed the best standards currently in place. Countries with world-leading standards should increase them further to reflect the levels of today’s best available technologies.
  • Governments need to embed clear, measurable appliance efficiency targets into their national climate goals. They must also track progress with standardized metrics to stay on course to meet the doubling efficiency goal.
  • All stakeholders across government, industry, and civil society must strengthen international and cross-sectoral collaboration to accelerate global energy efficiency gains. This cost-effective approach includes sharing technical expertise, conducting joint market surveillance, and harmonizing standards to overcome common barriers.

 

The Missing Piece of Energy Access: Why 15% of Energy Infrastructure Investment Must Go to Appliances

Globally, hundreds of millions of people lack electricity. Most solutions focus on extending power supply infrastructure, but in marginalized areas, low electricity demand makes the expense of such infrastructure hard to justify. Increasing the use of energy-efficient appliances in these areas can attract electricity supply investments while delivering climate benefits. Achieving sufficient levels of appliance use to meet these goals would require allocating 15% of supply-side investments, or $38 billion USD, toward demand growth between now and 2030. The funding should focus largely on improving appliance affordability.

Key Findings

  • Energy-efficient appliances are essential energy infrastructure, critical for achieving universal energy access and meeting climate mitigation and adaptation goals.
  • Bringing modern energy to the 666 million people who lack it (most of whom live in Sub-Saharan Africa) requires expanding power infrastructure to places with low electricity consumption.
  • Increasing appliance access across Africa could generate demand for 342 terawatt hours of electricity annually, creating a market worth approximately $50 billion USD that would catalyze accelerated power infrastructure development.
  • Focusing on expanding markets for energy-efficient appliances (as opposed to standard, less-efficient appliances) would provide many benefits, including avoiding an estimated 2.6 gigatons of CO2 equivalent emissions annually.

Recommendations

  • The IEA estimates that at least $50 billion USD of public investment annually is needed until 2030 to achieve universal energy access. CLASP analysis shows that 10–15% of this amount—about $7.5 billion USD annually, or $38 billion USD in total—should be devoted to improving appliance access.
  • Relevant decisionmakers should allocate 10–15% of power supply-side investments toward establishing sustainable electricity demand growth.
  • Public institutions should target investments to overcoming market failures that limit appliance use—in particular, a lack of affordability and consumer confidence.
  • All stakeholders should prioritize energy-efficient appliances over standard, less-efficient appliances.
