The new edition of the Energy Efficiency Market Report from the International Energy Agency (IEA) highlights a reduction in greenhouse gases, achieved by investment in energy efficiency. These investments, in the 29 IEA member countries since 1990, have abated a massive 10.2 billion tonnes of CO2 emissions. This equates to US$5.7 trillion of energy expenditure saved.

The report uses detailed country-by-country energy-efficiency indicator data and assesses the outlook for future progress. Energy-efficiency market snapshots are provided for several countries, including Australia. The snapshots include program highlights, energy demand targets and suggested priorities.

Energy-efficiency investments in the buildings sector are estimated to have been US$90 billion worldwide in 2014. The Energy Efficiency Market Report 2015 includes detailed examination of energy use across the buildings sub-sectors, factoring in the various end-uses such as HVAC and lighting. As energy efficiency codes, standards and programs are improved and more widely implemented, per-building investment is projected to increase.

Energy efficiency has directly reduced electricity consumption in OECD countries, requiring providers to adjust and adapt their business models.

Energy intensity, the amount of energy used to produce a nation’s gross domestic product, improved by 2.3% in 2014 in OECD countries, very close to the United Nations’ ‘Sustainable Energy for All’ target of 2.6% per year to stem global warming.
