The International Energy Agency (IEA) is known as the most authoritative source for global energy statistics. The IEA publishes its statistics in a series of annual and quarterly publications as well as through electronic data services.

For the first time in 1997, the IEA produced a compilation of its most used statistics in a booklet easily accessible to all – what is now the annual Key World Energy Statistics (KWES). Since then, the booklet has been hugely successful and has become a constant companion of energy analysts and policy makers.

Key World Energy Statistics contains timely, clearly presented data on the supply, transformation and consumption of all major energy sources for the main regions of the world. The interested business person, journalist or student will have at his or her fingertips the annual Australian production of coal, the electricity production in Japan, the price of diesel oil in Spain and thousands of other useful energy facts.

To respond to increasing requests of users, the IEA offers an iOS version of the KWES. With this application, you can access key statistics on more than 130 countries and regions including energy indicators, energy balances, prices, CO2 emissions as well as energy forecasts.

A sort function allows the user to rank countries by ascending and descending order according to a selection of indicators and tables can also be personalised by selecting specific countries and indicators. A search feature as well as a quick access menu and a favourites function are also available.

Not worth the time

Poor showing, not an interactive app at all. No time series data available, just a collection of PDF'd pie charts. This is about as useless as IEA's website.
