World electricity production by renewable sources between 2009 and 2012
World electricity production by renewable sources between 2009 and 2012 a7gOd
The table presents the yearly world production of electricity by five renewable sources, i. e. geothermal, wind, solar, hydraulic and bio-mass power plants. The data were collected from 2009 to 2012 and are shown in Terrawatt Hours.
Overall, the electricity production by sustainable sources increased steadily in time and for all the five types of power plants. For example, the geothermal power plants produced 67. 4 TWh in 2009, increased their production each year by about 1 TWh to finally reach 70. 4 TWh of electricity in 2012.
However, the development of renewable sources in electricity production differs significantly between the fields studied. While hydraulic power plants stood behind 3329 TWh in 2009 and 3663 TWh, which marks only a decent development, sun-based electricity production rose five times in the same period, from 21 TWh in 2009 up to 104. 5 TWh in 2012. Wind turbines also wittnessed a large increase in production, doubling their 2009 figure of 276. 4 TWh to 534 TWh in 2012. Bio-mass and geothermal power supplies had rather a smaller increase in production, similar to water based power plants.
