According to Paul Waide, a senior policy analyst with the IEA and one of the report's authors, «19 %
of global electricity generation is taken for lighting — that's more than is produced by hydro or nuclear stations, and about the same that's produced from natural gas.»
Offshore wind is a rising force, but remains for the moment a relatively marginal one at 0.2 %
of global electricity generation; wind and other marine technologies face stiff competition from a range of onshore options, including other low - carbon sources of generation.
Hydroelectricity was the next largest renewable source, providing 3 % of global energy consumption and 15 %
of global electricity generation.
Coal's share
of global electricity generation is projected to decline from about 40 percent in 2016 to less than 30 percent in 2040.
Coal still makes up 41 %
of global electricity generation and 29 % of primary energy demand.
Nuclear energy is a mature low - GHG emission source of baseload power, but its share
of global electricity generation has been declining (since 1993).
