Energy efficiency improvement in Europe in 2018.
Global energy intensity (total energy consumption per unit of GDP) declined by 1.3% in 2018, slightly below its historical trend (-1.6%/year on average between 2000 and 2017).
Energy intensity levels and trends differ widely across world regions, reflecting differences in economic structure and energy efficiency achievements.
China’s energy intensity improved by almost 40% between 2000 and 2018, and 2.7% in the last year, driven by energy efficiency policies focused on energy-intensive industries.
Over time, China has developed and applied energy intensity reduction targets in response to significantly high energy-intense industries, bringing with it a strong demand for energy efficiency services.
Energy intensity in the United States increased in 2018 (+0.6%) compared to a decreasing trend (-1.9%/year) over the years 1990-2017.
Energy efficiency improvements continued in the European Union, the region with the lowest energy intensity in the world, with a higher rate (-3.1% in 2018) compared to the annual rate of reduction -1.8%/year measured over the 2000-2017 period. Contributing to this result, however, were the weather conditions (mild winter)
The energy intensity in the CIS region has decreased continuously since 2000 (-2.7%/year) but remains the highest in the world (75% above the worldwide average).
The high energy intensity in the CIS, the Middle East, China and other Asian developing countries is explained by the dominance of energy-intensive industries, commodity exporting-based economies and low energy prices that do not encourage energy efficiency.
According to the Ministry of New and Renewable Energy (MNRE) of India, renewable power capacity in India has exceeded the 80 GW mark, with 80,460 MW of renewable capacity operational as of 30 June 2019, including 29,550 MW of solar capacity and 36,370 MW of wind power capacity. In addition, power purchase agreements (PPAs) have already been signed for an additional 9.2 GW of solar power projects.
According to the Short-Term Energy Outlook (STEO) released by the US Energy Information Administration (EIA), energy-related CO2 emissions in the United States are expected to reverse their 2018 trend (+3%) and to decline by 2.2% in 2019. Energy-related CO2 emissions would decrease by 114 Mt in 2019 and most of the drop would come from coal-related emissions (-13%, i.e. -168 Mt); this would be the largest decline in CO2 emissions from coal since 2015. Coal-related CO2 emissions are expected to decline by a further 3.6% in 2020.
According to the latest carbon inventory submitted by the Chinese Ministry of Environment to the United Nations, greenhouse gas (GHG) emissions in China rose by more than 53% between 2005 and 2014, reaching 12.3 GtCO2eq in 2014. These estimates don't take LULUCF (land use, land use change and forestry) into account: according to the Ministry of Environment, total GHG emissions including LULUCF still would have risen by 17% between 2010 and 2014 to 11.2 GtCO2eq.
According to the US Energy Information Administration (EIA), the installed capacity of utility-scale (above 1 MW) battery energy storage systems (BESS) in the United States could reach 2.5 GW by 2023.
