The given chart illustrates information on the proportion of fuel generated by renewable energy used in the transport sectors, as well as the European Union average, in six countries in 2009 and 2010.
Overall, Slovakia and Austria showed higher percentages in 2009, whereas the proportion of coal in other countries was higher in 2010. Consequently, the average percentage of fuel was slightly higher in 2010 than that in 2009.
Regarding Slovakia, the percentage of fuel was 9% in 2009, which was slightly higher than that in 2010 (8%). A similar trend could be seen in Austria, with a slightly lower figure than Slovakia, 6.5% in 2009 and 5% in 2010.
