The future of wind energy is bright. That’s according to the International Renewable Energy Agency (IRENA), whose new report “Future of the Wind” says the deployment of wind power is accelerating worldwide.

By 2050, the agency says, wind energy could account for 35% of global energy needs. However, for that to happen, the current capacity of wind energy would need to increase tenfold to 6,000 gigawatts, including 5,000 GW on land and 1,000 GW offshore.

“Wind power, along with solar energy, would lead the way for the transformation of the global electricity sector,” IRENA says. ”Onshore and offshore wind would generate more than one-third  (35%) of total electricity needs, becoming the prominent generation source by 2050.”

In addition, the report notes, the accelerated deployment of wind power will need to be coupled with deep electrification and increased energy efficiency. If that happens, we could achieve more than a quarter of total emissions cuts by 2050, or nearly 6.3 gigatonnes of carbon dioxide each year, thanks to wind energy.

Such a drastic reduction in global CO2 emissions, however, will necessitate greatly scaling up wind capacity worldwide in coming decades. “This entails increasing the global cumulative installed capacity of onshore wind power more than threefold  by  2030  (to 1,787 gigawatts )  and  nine-fold  by  2050 (to 5,044 GW) compared  to  installed  capacity  in  2018  (542 GW),” the agency says.

“For  offshore  wind  power,  the  global  cumulative  installed  capacity  would  increase  almost  ten-fold by 2030 (to 228 GW) and substantially towards 2050, with total offshore installation nearing 1,000 GW by 2050,” it adds.

Encouragingly, leading industrialized nations like Germany are embracing wind power. At present Germany boasts nearly 1,500 offshore wind turbines producing a combined capacity of 7,516 MW. The country added more than 1,100 MW of new wind power to the grid last year. “Electricity from offshore wind energy is cost-effective, reliable and constantly competitive,” Germany’s wind energy associations stresses.

Industry analysts say that with well-considered government policies in place Germany’s total capacity of wind energy could balloon to 20 GW within a decade. They argue that by 2035 a total capacity of up to 35 GW in offshore wind power will be required in the country whose government has promised to shutter all coal-fired plants before that date.
