In 2009, oil remained the main source of energy in the EU27, with a share of 37% in the total gross inland energy consumption. However, there have been changes in the mix of sources contributing to gross inland energy consumption over the last decade. The share of renewable energy has almost doubled, from 5% of total gross inland energy consumption in 1999 to 9% in 2009, while gas rose from 22% to 24%. Nuclear energy remained almost stable at 14% during this period, while oil fell from 39% to 37% and solid fuels from 18% to 16%.
