Information regarding worldwide generation of electricity from renewable sources from 2009 to 2012 is depicted in the tabular chart.

At a glance, the generation of electricity from all these four sources across the world increased throughout the time period.

It is clear from the table that the most prominent contributor of renewable energy was from the hydraulic source. The units of power generated from it inclined from 3329 TWh in 2009 to 3363.4 TWh in 2012. Bio-mass and wind also generated significant amount of energy during this period. In 2009, an average of around 261 TWh of electricity was produced from these sources. It increased to 326.2 and 534 TWh. The surge in the power generation was almost 80 TWh in case of the former source and was nearly double in case of the latter.

Meanwhile, the power generation from the sun saw almost a five-fold increase during this period (21 to 104.5 TWh). The least growth in the electricity production was from the Earth’s heat, which was just 3 TWh.
