Energy Efficiency 2025 Executive summary
…savings on the table. Many appliances being sold today are often only half as efficient as the best available models. As technologies have become more efficient in recent years, energy efficiency standards have not progressed at the same pace. For example, the efficiency of best-in-class lightbulbs doubled in the last 15 years, while minimum performance standards have only gone up by 30%.Increased access to air conditioners has pushed up cooling-related electricity demand. Higher living standards have allowed more people to afford much-needed cooling technologies such as air conditioners, especially in emerging economies. In fact, energy…

Energy Efficiency 2025 Industry
…a large part of energy demand is used for heat production, and much of this required heat falls within low-temperature ranges (up to 200°C), which could be electrified with existing technologies, such as heat pumps. What are the key measures to accelerate progress? Upgrading motor systems is a key area to promote industrial efficiency. Countries can implement more stringent standards for new motors and equipment, such as fans, pumps and compressors. Additionally, promoting the use of variable-speed drives, through regulations and targeted incentives, can further increase savings in variable-load applications.Electrifying low-temperature heat using heat pumps…

Energy Efficiency Policy Toolkit Industry
…accelerate energy efficiency progress by facilitating knowledge exchange and the sharing of best practices. They can also work in conjunction with other government policies to boost uptake by supporting the dissemination of information on incentives and available funding to industry. Governments should consult local and national industry representatives and associations and profit from the insights of local industrial experts to determine the most effective information instrument for their country.Incentives such as facilitating access to finance and energy efficiency obligation schemes can be effective tools for encouraging private sector stakeholders to advance energy efficiency priorities. Obligated parties often achieve savings…

Energy Efficiency Policy Toolkit Transport
…energy intensity improvement by 2030 would require the efficiency of cars to improve by 5% each year. An integrated policy approach combining regulation, information and incentives is the most effective way to achieve this goal.Regulations such as fuel economy standards and heavy-duty vehicle standards encourage manufacturers to introduce more efficient vehicles, thereby significantly reducing greenhouse gas emissions. Countries with regulations and/or efficiency-based purchase incentives in place improve efficiency on average 60% faster than countries without such policies. Information tools such as vehicle labels help inform consumers of a vehicle’s fuel economy and running cost savings…

Global Methane Tracker 2025 Overcoming barriers to abatement
…measures across the energy sector would be cost-effective to deploy in the presence of a greenhouse gas emissions price of about USD 20/tCO2‑eq. Several factors explain why methane emission reduction measures have not been deployed more widely. For example, companies could be unaware of the scale of the problem or the available solutions. There may be higher-profile opportunities competing for investment resources, or leadership may perceive methane abatement as more costly than it is. There may be split incentives, whereby equipment owners do not directly benefit from reducing methane leaks, the contractual terms prevent methane savings from affecting…

Ramping up Heat Pumps in Moldova: A Roadmap Building the market
…of existing government incentives to promote heat pumps, especially since these have only been introduced in recent years. The 2024-2025 energy challenges stemming from the gas transit shut-off to Ukraine, alongside progress in diversifying Moldova’s natural gas supplies, provide a timely opportunity to promote the benefits of heat pumps.Awareness campaigns on heat pumps will be key to educating the public on the long-term cost savings potential for households as well as the environmental benefits. They will also help dispel some of the common myths observed in other countries, such as concerns over heat pump performance…

World Energy Outlook 2025 Net Zero Emissions by 2050
…savings from lower fuel prices together with efficiency gains mean that households face costs for energy services comparable to those of today through to 2035, and lower still in the longer term. Fuel importers benefit too as import bills are cut by about two-thirds. Electricity takes on a bigger role to meet energy demand, underlining the significance of electricity security, and the need for secure and diversified supply chains for critical minerals and energy technologies. A pathway to return temperature rise below 1.5 °C The NZE scenario sees temperatures rise by around 1.65 °C above pre-industrial…
