According to data from Bloomberg New Energy Finance (BNEF), in 2016, global electricity installed capacity was 6,719 GW, of which coal power accounted for 30%, followed by natural gas power generation (24%), hydropower (17%), onshore wind power (7%), Fuel oil (6%), photovoltaic (5%), nuclear power (5%). It can be seen that in 2016, the proportion of fossil energy power generation capacity reached 60%.

BNEF predicts that the global power installed capacity will reach 13,919 GW in 2040, and the photovoltaic installed capacity will reach 32% (22% utility-scale photovoltaic power stations, 10% small photovoltaic systems), followed by onshore wind power (14%), natural gas Power generation (14%), coal power (13%), hydropower (12%), nuclear power (2%). From this point of view, by 2040, wind power photovoltaic installations will account for 46%, but due to the lower capacity factor (years of power generation hours), BNEF estimates that wind power photovoltaic power generation will account for 34%.

However, the forecasts of other agencies are much lower than those of BNEF. For example, the International Energy Agency (IEA) believes that wind power photovoltaics will account for about 16% of total power generation in 2040 and only 2.9% of primary energy consumption.
