In recent decades, wind turbines have become a familiar sight in many countries. Onshore wind projects around the world now consistently deliver electricity for USD 0.04 per kilowatt‑hour (kWh), with some projects achieving as low as USD 0.03/kWh. Yet up-to-date cost data and reliable projections of future costs remain limited.
The “learning curve” — a concept borrowed from manufacturing — assesses the rate at which production costs fall as deployment grows due to manufacturing and technology improvements. As an analytical tool, the curve captures past evolution and is a useful tool for assessing potential future cost trends for a given technology. In short, it provides a useful estimate of how future costs will fall as deployment (measured in some kind of physical units) grows. Continue reading Onshore Wind Industry Learning Fast
Spurred by ambitious national commitments, international agreements and rapid technological progress, governments are increasingly choosing renewable energy to expand their countries’ power infrastructures. In 2014, renewables provided 23% of power generation worldwide, and with the adoption of more ambitious plans and policies, this could reach 45% by 2030.
Amid this accelerating transition, the variability of solar and wind energy — two key sources for renewable power generation — presents new challenges. It also raises questions, like ‘How do you power a country when the wind isn’t blowing or the sun isn’t shining?’ and ‘How does variable power fit with the delivery of reliable electricity?’

In 2002, Denmark commissioned the world’s first commercial-scale offshore wind power plant. With an installed capacity of 160 megawatts (MW), the Horns Rev plant set the stage for a storm of ever growing farms with larger turbines; by the end of 2015 there was 13 gigawatts (GW) of installed offshore wind capacity in the world. And while most offshore plants are located in Europe, innovations are positioning the technology to become a leading global power generator in the future.
IRENA’s latest report Innovation Outlook: Offshore Wind, released today at the 15th World Wind Energy Conference and Exhibition in Tokyo, anticipates that offshore wind capacity could grow from 13 GW in 2015 to 400 GW by 2045. Continue reading A Gale of Innovation: the future of offshore wind
