Wind power on the verge of a boom

The International Energy Agency recently updated its technology roadmap for wind power, and increased from 12 to 18% the target proportion of the world's electricity generated by wind by 2050.

The International Energy Agency recently updated its technology roadmap for wind power, and increased from 12 to 18 percent the target proportion of the world's electricity generated by wind by 2050. The scenario the agency put forth in its report depends on offshore wind, which it expects to comprise 25 percent of total wind power by 2050. The cost of offshore wind farms is gradually decreasing, lending credence to this prediction.

In order to achieve its target, the agency reports that rapid scaling of annual wind power capacity installed will need to occur. This capacity will need to be at 65 gigawatts by 2020, 90 GW by 2030 and 104 GW by 2050. These are annual numbers referring to the capacity of wind installations made in a given year.

“Turbines are getting higher, stronger and lighter,” according to the IEA, “while masts and blades are growing even faster than rated capacity, allowing turbines to capture lower-speed winds and produce more regular output.”

Maintaining existing turbines in the best possible condition and ensuring all new installations benefit from the improvements mentioned above is crucial for energy companies that decide to deal in wind. Firms can help with maintenance and construction of turbine components to ensure an efficient and profitable wind farm.
