Global installed power capacity by source 2019

The electricity generating capacity for renewables worldwide has increased to over two terawatts. By 2019, hydroelectric and non-hydroelectric renewable sources had a combined power capacity of nearly 2.5 terawatts. However, this was still far lower than the capacity of all fossil-based energy sources. Coal and peat are the greatest source for electricity generation in the world. As of 2018, they account for 38 percent of total power production, with natural gas following, at23 percent.

Renewables set to surpass fossil fuels by 2040

Despite the continued dominance of fossil fuels, the share of renewables in global electricity generation has seen greater year-on-year growth, reaching over 26 percent by 2018. The cost of renewables' deployment has fallen over time, making them increasingly more cost effective and common around the world. As renewable technologies become more economically viable, these sources gradually replace conventional fossil fuels. By 2040, projected renewable electricity generation is expected to amount to 21.66 trillion kilowatt hours.

Electricity capacity explained

Generation capacity is a measure of the maximum power output, the amount of electricity a generator can produce at full power. There are three main types of capacity. Nameplate generating capacity is determined by the generator manufacturer. Net summer generation capacity is determined through performance tests during the peak demand in the summer months and in contrast, net winter capacity is determined during peak demand in the winter.
