Until we scale up such an energy infrastructure, the world will continue to face two energy problems: hundreds of millions of people lack access to sufficient energy, and the dominance of fossil fuels in our energy system
We see that global energy consumption has increased nearly every year for more than half a century. The exceptions to this are in the early 1980s, and 2009 following the financial crisis. Global energy consumption continues to grow, but it does seem to be slowing — averaging around 1% to 2% per year.
Energy efficiency has contributed more to the nation''s energy needs over the last 40 years than oil, coal, natural gas, or nuclear power. Not only does efficiency reduce dangerous climate
World energy production amounted to 617 EJ in 2019 – a 2% increase from 2018. This
World Energy Efficiency Day, celebrated next month on March 6, serves as a poignant reminder of the critical need to optimize our energy consumption patterns. This day, observed globally, is not merely an annual ritual, but a call to action. When discussing energy efficiency, it is imperative to explore the nuanced economic
Energy Efficiency 2023 - Analysis and key findings. A report by the International Energy Agency.

In Europe, residential and commercial gas demand
The World Energy Outlook 2023 provides in-depth analysis and
In the Stated Policies Scenario, primary energy demand expands by around a quarter between 2018 and 2040 at an average annual growth rate of 1%. This rate is slower than in the past (it was 1.4% between 2010 and 2018, and 2.7% in the preceding decade) as energy consumption and economic growth continue to decouple.
Energy efficiency is the use of less energy to perform the same task or produce the same result. Energy-efficient homes and buildings use less energy to heat, cool, and run appliances and electronics, and energy-efficient manufacturing facilities use less energy to produce goods. Energy efficiency is one of the easiest and most cost-effective
This report presents and evaluates energy efficiency policies in 63 countries, with a specific focus on five policy measures: Minimum energy efficiency standards for household electrical appliances; Innovative energy efficiency funds; Voluntary/negotiated agreements on energy efficiency/CO2; Local energy information centres; Packages of measures.
Every 5 March since 1998 it is World Energy Efficiency Day. The initiative, which emerged in Austria during the First International Meeting on Energy Efficiency, aims to raise awareness of the need to reduce energy consumption through reasonable and sustainable energy use.. Contrary to what many people think, improving energy efficiency does not

In Thailand, for example, households with a budget of USD 350 can purchase a low-efficiency unit or one that is 50% more efficient for the same price. Buying the more efficient unit could result in savings of up to USD 2 000 over its lifetime and cut electricity bills almost in half.
Energy Efficiency 2023 is the IEA''s primary annual analysis on
In 2021, global energy intensity – a key measure of the economy''s energy efficiency – is expected to improve (that is, to fall) by 1.9% after improving by only 0.5% in 2020. Over the past five years, energy intensity has improved on average by 1.3% a year, down from 2.3% between 2011 and 2016, and well below the 4% described in the Net
