All forms of energy (including oil, gas, coal, nuclear, and renewables) receive, or can receive, public incentives. On average, fossil fuels have obtained significantly more incentives compared to renewable sources. According to the Nuclear Energy Institute (NEI), 70% of all energy subsidies from 1950 to 2016 went to fossil fuels in the form of tax concessions and other programs. By contrast, green energy only received 17%, and the geothermal sector got a meager 1%. Most of the funds received were spent to incentivize research and development activities.
