WORLDWIDE: In its New Energy Outlook 2017, published in June, Bloomberg New Energy Finance (BNEF) suggested $3,300 billion would be spent on investments in wind energy between now and 2040.
Investments in 2016 were estimated at $107 billion, so the annual amount coming in is expected to rise.
BNEF expects investment in wind to grow faster than for solar. By 2040, these two renewable technologies together may account for 34% of global electricity generation.
The BNEF report is one of several that have been published recently. The projections vary, as the chart below illustrates.
