We’ve just released the 2019 edition of the IEA World Energy Balances databases, with complete energy balances and indicators for over 160 countries and regions up to 2017 and selected data for 2018.
The latest data show that world energy production was 14 035 Mtoe in 2017 – a 2.2% increase compared to 2016.

This increase was driven by coal and natural gas, both increasing by more than 120 Mtoe in 2017, and renewables other than hydro and biofuels, which grew by slightly more than 30 Mtoe.
Other databases updated last week include: Coal Information, Electricity Information, Natural Gas Information, Oil Information and Renewables Information – all of which can be accessed through IEA data services.
… and the 2019 energy efficiency indicators database
We’ve also just released the 2019 edition of the IEA energy efficiency indicators database, featuring detailed energy end use and activity data from 2017 for the residential, services, industry and transport sectors.
The latest data shows that despite significant energy savings from efficiency in the residential sector since 2000, the energy intensity of appliances hasn’t generally declined – a worrying trend given that appliances are the second-largest end use in IEA countries after space heating. These latest data suggest that more ambitious energy efficiency policies will be necessary to outpace recent patterns, for example the more than doubling of personal computer ownership over the last 20 years.
Collaborating on energy technology innovation
It is unlikely that any single country will be able to solve all of its energy and climate problems alone. International collaboration can help countries accelerate innovation processes by identifying common priorities and challenges, tackling pressing innovation gaps, sharing best practices to improve performance, reducing costs and reaching broad deployment of clean energy technologies. Given this massive potential, the fundamental question is not if countries should collaborate, but rather who should collaborate and how they can do so efficiently.
In our latest commentary, analysts Jean-Baptiste Le Marois and Claire Hilton outline three priorities for energy technology innovation partnerships: enhance collaboration among existing initiatives, focus on emerging markets, and strengthen public-private cooperation

Growing electricity demand for space cooling means that energy-related CO2 emissions are on the rise. Electricity in China is produced principally with coal-fired power generation, and emissions related to space cooling demand in buildings represented around 250 million tonnes of CO2 in 2017, 2.8% of total energy-related CO2 emissions in China.
This corresponds to roughly one-fourth of global CO2 emissions from space cooling.

Two key characteristics determine the impact of different greenhouse gases on the climate: the length of time they remain in the atmosphere and their ability to absorb energy. Methane has a much shorter atmospheric lifetime than CO2 but it is a much more potent greenhouse gas, absorbing much more energy while it exists in the atmosphere.
The most common way to combine these factors to estimate the effect on global warming is the global warming potential (GWP). The Intergovernmental Panel on Climate Change (IPCC) has indicated a GWP for methane between 84-87 when considering its impact over a 20-year timeframe and between 28-36 when considering its impact over a 100-year timeframe. This means that one tonne of methane can considered to be equivalent to 28 to 36 tonnes of CO2 if looking at its impact over 100 years.
