In 2018, nuclear power was responsible for 2,701 Terawatt-hours (TWh) of electricity generation, compared to 4,193 TWh for hydropower and 2,480 for renewables. In comparison, coal produced more power than all three categories combined. However, the growth rates of the different categories of electricity generation tell a different story. Over the past decade, from 2007 to 2017, global electricity generated by coal grew at an annual average of 1.7%. Nuclear generation over that time actually declined annually by 0.4%, a consequence of the Fukushima Daiichi nuclear disaster in 2011. Hydropower generation grew at an average annual rate of 2.8%. These growth rates are indicative of mature power sources. But contrast those growth rates with those of modern renewables. From 2007 to 2017, the Renewables category grew at an average annual rate of 16.4%. But within that category, power from geothermal and biomass grew at an annual average of 7.1%. Wind and solar power, by contrast, grew at an annual average of 20.8% and 50.2%, respectively, over the past decade.
