The recent acceleration in global energy efficiency gains risks slowing down if governments do not maintain their focus on implementing new efficiency policies, according to a new report by the International Energy Agency.

China is the world’s largest consumer of coal, but it also has more wind and solar generation capacity than any other country in the world. This is just one insight drawn from the new and updated edition of Key World Energy Statistics (KWES) released by the IEA. The new version of KWES still provides headline data on all fuels, and now also contains additional information highlighting the rapid growth of renewable technologies, for example that in four countries wind generation provided more than 10% of all electricity, with solar providing more than 5% in two countries.

World Energy Balances 2017 offers final and complete energy balances for 1971 to 2015, with supply estimates for 2016, by country and region. This overview from World Energy Balances 2017 contains a summary of the most recent energy trends.

The road freight sector is both a key enabler of economic activity and a key source of energy demand, in particular oil. Trucks rely almost exclusively on oil-based fuels. They are the second largest source of global oil demand, following passenger cars and at a similar level as the entire industry sector.

Renewables Information 2017 includes detailed renewables and waste data by country and by product for OECD countries up to 2015, with provisional data for 2016. It also contains summary tables of renewables and waste data for non-OECD countries up to 2015.

The number of electric cars on the roads around the world rose to 2 million in 2016, following a year of strong growth in 2015, according to the latest edition of the International Energy Agency’s Global EV Outlook. China remained the largest market in 2016, accounting for more than 40% of the electric cars sold in the world.

Each year, the IEA’s Tracking Clean Energy Progress (TCEP) report examines developments across a range of clean energy sectors and technologies. The TCEP uses benchmarks for 2025 as modelled in Energy Technology Perspectives 2017, as well as the milestones identified in the IEA Technology Roadmaps.

In November 2015, the leaders of Asia-Pacific Economic Co-operation (APEC) economies, reaffirmed their landmark 2009 commitment to “rationalize and phase out over the medium term inefficient fossil fuel subsidies that encourage wasteful consumption while recognizing the importance of providing those in need with essential energy services”.

Limiting the rise in global mean temperature to well below 2°C would require an energy transition of exceptional scope, depth and speed, according to an analysis by the International Energy Agency, including a doubling of annual average energy-related investments from current levels.

Wind and solar PV have become among the cheapest options for meeting power demand in a growing number of countries globally. As these variable renewable energy (VRE) technologies differ from conventional generation technologies, power systems will need to adapt in line with their ongoing build-out.
