The Commission is in the process of updating some of the content on this website in light of the withdrawal of the United Kingdom from the European Union. If the site contains content that does not yet reflect the withdrawal of the United Kingdom, it is unintentional and will be addressed.

The purpose of the calculator is to build an energy pathway that hits the 80% CO2 emission reduction target at the top of the page. As you get closer to achieving this the arrow will move to the right.   The calculator models what is thought to be physically and technically possible in forty-two different sectors. It is based on scientific and engineering data and was built in collaboration with a wide range of organisations from inside and outside of government.

In 2018, primary energy intensity – an important indicator of how much energy is used by the global economy – improved by 1.2%, the slowest rate since 2010. This was slower than the 1.7% improvement in 2017 and marked the third year in a row the rate has declined. It was also well below the average 3% improvement consistent with the IEA Efficient World Strategy.

Energy poverty, or fuel poverty, is often defined as a situation where low-income households are not able to adequately provide basic energy services in their homes and for their transport at affordable cost. A widely used criterion is to consider a household in fuel poverty when it spends more than 10% of its income on energy.  But there is no consensus on a unique and explicit definition of the phenomenon as it is complex and has different causes and effects (temperature feelings, restriction behaviour…).

The buildings and construction sector accounted for 36% of final energy use and 39% of energy and process-related carbon dioxide (CO2) emissions in 2018, 11% of which resulted from manufacturing building materials and products such as steel, cement and glass. This year’s Global Status Report provides an update on drivers of CO2 emissions and energy demand globally since 2017, along with examples of policies, technologies and investments that support low-carbon building stocks.

Having reliable data and indicators on how energy is used is key to informing and monitoring the effectiveness of energy efficiency policies. Highlighting the importance of such data, the IEA has updated its Energy Efficiency Indicators database with annual data from 2000 to 2016, with expanded geographical coverage and an interactive visualization tool that better shows country-specific final energy consumption patterns across all end uses.

Numerous studies and surveys indicate that typically-installed HVAC equipment operate inefficiently and waste considerable energy due to varied installation errors (faults) such as improper refrigerant charge, incorrect airflow, oversized equipment, and leaky ducts. This article summarises the results of a large United States (U.S.) experimental/analytical study of the impact that different faults have on the performance of an air-source, single-speed heat pump (ASHP) in a typical U.S. single-family house.

This slide presentation describes the main results of a study operated by the National Institute of Standards and Technology (NIST) in the USA, to understand the impact of commissioning common faults on the energy consumption of an air-to-air heat pump installed in a single-family house.
