Technology Helping Wind Turbines Overtake Fossil Fuels for Energy


Texas_Wind_TurbinesAlthough wind turbines do not appear to have changed much over the years, the technology behind them has gotten considerably more sophisticated. This has led to the increase in the amount of electricity wind turbines can generate and has lowered the cost of wind power.

General Electric’s 2.5-120 wind turbine is a leader in the new turbine technology. In the past, general turbine output has been 2.85, but GE’s is 2.5 megawatts while generating 15% more kilowatt hours. GE attributes this efficiency to sensor arrays and more sophisticated algorithms that account for better operating and monitoring the turbine to keep it spinning long past the point of shutdown for other turbines.

Wind power is now as inexpensive as fossil fuels and is becoming increasingly competitive with them. For instance, in 1991, wind power costs approximately 15 cents per kilowatt hour. Now it is 6.5 cents per kilowatt hour. For comparison’s sake, this year new natural gas plants will generate electricity at 6.5 cents per kilowatt hour.

In January, a report released by the Electric Reliability Council of Texas demonstrated that latest data on wind turbine performance and costs suggests that wind power is likely to be more cost-effective than natural gas over the next 20 years.

Initially, the council expecting the findings to sway in the direction of natural-gas plants not wind power but later conceded that wind power will account for the majority of the new generating capacity added to Texas.

Wind power is quickly becoming a competitor with fossil-fuel power, but the scale will be limited to the grid’s ability to handle the current intermittency.

  1. Obama’s energy policy is right. Japan’s FiT in July is among the highest in the world. Japan’s FiT is shaking the renewable energy market. New solutions will be showed in Japan. This is it! Floating wind turbine is one of the best solutions for USA and UK. UK has more install places around its shores than any other in the world. USA has Atlantic Coast. As you know, Every year Some typhoons arrive Japan. The typhoon has strong wind. Floating wind turbines must have constructed to resist typhoons. So they have to reduce vibration to install floating wind turbines on the sea. Because, it makes many kinds of problems! It’s increasing the durability problem of floating wind turbine. Vibration’s caused by wind, waves and external forces. New Floating Body Stabilizer for floating wind turbines has been created in South Korea. The Floating Body Stabilizers generate drag force immediately when floating wind turbines are being rolled, pitched and yawed on the water. Recently, this Floating Body Stabilizers have been used to reduce vibration of floating solar panels in South Korea. You can see New Floating Body Stabilizer videos in YouTube. http://youtu.be/O2oys_YHhCc, http://www.youtube.com/watch?v=nA_xFp5ktbU&feature=youtu.be.
