What proportion of wind power photovoltaics will account for global power generation in 2040? IEA sa

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.
