When one drops off it's easier for another to pick up the slack. Wind power is less effective as a "shock absorber" to shifts in supply and demand, according to the energy analyst.

After three years of decline, global energy investment stabilized in 2018 at over USD 1.8 trillion.

Half (49%) of the net electricity generated in the EU-28 in 2017 came from combustible fuels (natural gas, coal and oil), while a quarter (25%) came from nuclear power stations. Among the renewable energy sources, the highest share of net electricity generation in 2017 was from wind turbines (11.4%), followed by hydropower plants (10.4%).

The underlying assets of the Libra fund will be made up of bank deposits and other low risk government securities.
