Urbanization, rising temperatures, and more frequent heat waves in India are driving cooling demand higher. Further, as living standards rise and electricity reaches more homes across India, sales of room air conditioners (ACs) are growing. The room AC stock has skyrocketed from 2 million units in 2006 to approximately 30 million units in 2017. Air conditioners are now viewed as a necessity for a healthy lifestyle, similar to the perception of refrigerator ownership in the 1990s. But, ACs also burden electric grids with greater peak power demand, leading to higher power plant fuel consumption and increasingly poor air quality. Increased AC use also exacerbates harmful climate change caused by emissions of carbon dioxide from power generation and the release of refrigerants such as hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs), potent heat trapping gases used in air conditioners. For the room AC market to grow sustainably, “climate-friendly” room ACs – those that are both energy efficient and use climate- safe refrigerant gases – are needed.
Cooling is finally coming in from the cold. After many years on the side lines of the energy debate, the importance of cooling to modern ways of living for all, but also the damage it causes to the environment and our health, is being recognised. And so it should be sustainable, affordable artificial cooling with minimal global warming or environmental impact is nothing less than critical to societal, environmental and economic sustainability worldwide. This report explores new outcome and needs-driven, integrated, system- level approaches that re-imagine the way we use and deliver cooling. In so doing it seeks to understand the portfolio of cooling needs, the size and location of the multiple thermal, waste and ‘wrong-time’ energy resources available, and then identify the novel energy vectors, thermal stores and cooling technologies appropriate for the societal, climate and infrastructure context. In short, what we call the Cold Economy: transitioning from technology to system.
This report is the first to define and quantify the magnitude of the cooling access challenge, including an assessment of countries facing the biggest risks, measured by extreme heat, food losses, and damaged or destroyed vaccines and medicines. The report illustrates the social and economic risks of ignoring the challenge and the enormous economic and business opportunities of a concerted effort to provide sustainable cooling.
The International Energy Agency (IEA) is shining a spotlight on some of the blind spots of energy policy – issues that get little attention but are of crucial importance. The growth in global demand for space cooling is such a blind spot: it is one of the most critical yet often overlooked energy issues of our time. If left unchecked, energy demand from air conditioners will more than triple by 2050, equal to China’s electricity demand today. This report highlights the threats associated with rising, unchecked cooling demand. It provides key insights into current and future trends in cooling, and it proposes policy responses to achieve a more sustainable pathway.
Energy Efficiency 2018, the sixth edition in the IEA Market Report Series, is the global tracker of trends and indicators in energy efficiency and an invaluable resource for energy efficiency policy makers and market actors. This year’s report provides a special feature in the form of a new World Energy Outlook Efficient World Scenario, which answers the question: What would happen if policy makers realised all the economically viable potential for energy efficiency that is available with existing technologies? The report also presents a detailed analysis of energy efficiency trends and drivers in the six major emerging economies of Brazil, China, India, Indonesia, Mexico and South Africa. Energy Efficiency 2018 presents the most comprehensive analysis of current and future energy efficiency trends ever produced by the International Energy Agency, and its insights offer direct pointers to policy makers as to what policy solutions are available to deliver the economic, environmental and social benefits of energy systems that are as efficient as possible.
This factsheet provides an overview of the growing Indian AC market, strategies to advance climate- friendly ACs, and market opportunities under the Montreal Protocol.
The chapter covers fluorinated GHGs, namely hydrofluorocarbons (HFCs). The Deep Decarbonization Pathways Project reports seek to reduce HFC and hydrochlorofluorocarbon (HCFC) emissions in the United States by 96 million metric tons (MMT) CO2 equivalent (CO2eq) by 2050. HFCs replaced chlorofluorocarbons (CFCs) and HCFCs that have been phased out under the Montreal Protocol on Substances That Deplete the Ozone Layer because they were depleting the stratospheric ozone layer. Due largely to their use as substitutes for CFCs and HCFCs, HFCs are the fastest growing GHGs in the United States, growing from 0.3 MMT CO2eq in 1990 to 149.4 MMT CO2eq in 2010. EPA, many states, and businesses have already begun acting to speed the phasedown of HFCs in the United States. There are a number of legal pathways at the fed- eral, state, and local levels that would further reduce emissions of HFCs and speed markets to a safe transition to environmentally friendly alternatives. Additional climate benefits can be realized by simultaneously improving the energy efficiency of equipment during the transition away from high-global warming potential (GWP) refrigerants.
Climate change is an urgent problem requiring urgent solutions. This report lays out urgent and practical solutions that are ready for implementation now, will deliver benefits in the next few critical decades, and places the world on a path to achieving the longterm targets of the Paris Agreement and near-term sustainable development goals. The solutions consist of four building blocks and 3 levers to implement ten scalable solutions described in this report by a team of climate scientists, policy makers, social and behavioral scientists, political scientists, legal experts, diplomats and military experts from around the world.
Hydrofluorocarbons (HFCs) emitted from uses such as refrigerants and thermal insulating foam, are now the fastest growing greenhouse gases (GHGs), with global warming potentials (GWP) thousands of times higher than carbon dioxide (CO2). Because of the short lifetime of these molecules in the atmosphere, mitigating the amount of these short-lived climate pollutants (SLCPs) provides a faster path to climate change mitigation than control of CO2 alone. This has led to proposals from Africa, Europe, India, Island States, and North America to amend the Montreal Protocol on Substances that Deplete the Ozone Layer (Montreal Protocol) to phase-down high-GWP HFCs.
This report calculates the benefits of leapfrogging to superefficiency and low global warming potential refrigerants in room air conditioning.
Over the past half century, California has provided a remarkable example for the world by achieving dramatic reductions in air pollution, while continuing to grow economically. In this report, we propose a set of strategies for combating climate change and growing the economy in California, the nation and the world, while building present-day and intergenerational wealth, and improving the well-being of people and the planet.
