In the past ten years, the wind energy generation has been increasing, reaching 19.8 terawatt-hours in 2018. This was an increase of 19 terawatt-hours compared to 2008. Similarly, energy generation from solar power expanded, especially in recent years, where the generation from this source rose from 20 gigawatt-hours in 2014 to nearly 2,892 in 2017.
The growth in energy generation was also reflected in hydropower contribution. In 2018, the amount of energy generated through hydropower totalled 59.5 terwatt-hours, making it the most prominent source of renewable energy generation in Turkey. On the other hand, hydropower consumption stood at 13.5 million metric tons of oil equivalent that year.
When it comes to bioenergy capacity, it increased more than fivefold over the last decade, reaching 572 megawatts as of 2018. That year, geothermal cumulative installed capacity amounted to 1,283 megawatts. When compared to other renewable energy sources, geothermal and biomass souces were a relatively minor contributor towards energy generation in Turkey. In 2017, the energy generation from these sources totaled ten terawatt-hours.
