Wind Power: Healthy and Growing! | 04/02/13
by John Brian Shannon
Global wind power growing at an exponential rate
For example, China has now installed more wind turbines than any other country. China began 2011 with 41.5 gigawatts of installed wind power capacity and is adding more wind turbines to their grid almost daily.
And by 2015 (one year ahead of schedule) China’s citizens will enjoy 100 gigawatts of clean, wind powered electricity. Wind power surpassed nuclear energy in 2012, to become China’s 3rd largest source of electrical power.
By 2020, they plan to have 200 gigawatts of wind power, which will displace many billions of tons of airborne emissions from coal-fired power plants.
The United States is second with 47 gigawatts of wind power capacity (at the end of 2011) and must add 305 gigawatts of wind power by 2030 to reach the goals set out in the U.S. Department of Energy 2008 report 20% Wind Energy by 2030 (downloadable PDF) which predicted that wind power could meet 20% of all U.S. electricity demand by 2020.
The use of wind power in the United States has expanded quickly over the last several years. Construction of new wind power generation capacity in the fourth quarter of 2012 totaled 8,380 megawatts (MW) bringing the cumulative installed capacity to 60,007 MW.
This capacity is exceeded only by China. For the 12 months from November 2011 to October 2012, the electricity produced from wind power in the United States amounted to 137 terawatt-hours, or 3.4% of all generated electrical energy.
The U.S. wind industry generates tens of thousands of jobs and billions of dollars of economic activity.
Wind projects boost local tax bases, and revitalize the economy of rural communities by providing a steady income-stream to farmers with wind turbines on their land. – Wikipedia
Wind energy has grown exponentially in the last decade, with an average increase of 29.7%/year. At an exponential growth of 29.7%, the U.S. would obtain 20% from wind by 2020. — Image courtesy of Wikipedia
If you think that only large countries can use the wind to create clean and fuel-free electrical energy, read: Denmark Sets Goal of 100% Renewable Energy by 2050. Denmark has proven to the world that when citizens back government efforts towards sustainable energy — the transition to 100% green energy is possible. The Danes are making it look easy.
It is time to harness that wind and produce clean electricity from it, create jobs and make profit by it, while enjoying the benefits of clean air as more wind farms displace fossil-fuel power plants!

Solar power tends to be complementary to wind. On daily to weekly timescales, high pressure areas tend to bring clear skies and low surface winds, whereas low pressure areas tend to be windier and cloudier. On seasonal timescales, solar energy peaks in summer, whereas in many areas wind energy is lower in summer and higher in winter.[nb 3]
Thus the intermittencies of wind and solar power tend to cancel each other somewhat.
In 2007 the Institute for Solar Energy Supply Technology of the University of Kassel pilot-tested a combined power plant linking solar, wind, biogas and hydrostorage to provide load-following power around the clock and throughout the year, entirely from renewable sources.
Wind power has low ongoing costs, but a moderate capital cost. The marginal cost of wind energy once a plant is constructed is usually less than 1-cent per kW·h. This cost has reduced as wind turbine technology improved.
