Utility scale wind turbines have become so technologically advanced that they have improved the cost of energy (COE) of wind enough to compete with today’s conventional energy sources. The ensuing reduction in COE has been the result of two governing forces: public policy and technological innovation. (more…)
The project was developed by Gehrlicher Solar America, which earlier in 2013 opened a regional (more…)
General Electric recently introduced a wind turbine equipped with a storage battery, creating a type of “hybrid” turbine that industry leaders hope will improve the integration of intermittent energy sources onto the grid and reduce the costs of wind power. (more…)
One of the major trends in wind power is ever larger turbines for offshore use. This raises many technical challenges, including how to transport and install such large components at offshore sites.
General Electric recently announced it had started testing the prototype of what it calls the world’s most efficient high-output wind turbine. The new 2.5-120 is being tested in Wieringermeer, Netherlands.
The 2.5-120 harnesses the power of the Industrial Internet to analyze tens of thousands of data points (more…)
A new research report published at EWEA 2013 by consultancy Totaro & Associates has catalogued over 27,500 global patent filings related to horizontal-axis, utility-scale wind turbine technology. Totaro & Associates CEO and Principal, Philip Totaro says that, “We estimate there are ~45,000 to 50,000 global filings in total, and we are continuing our research to catalogue and (more…)
One of the business plans I support is a breakthrough in wind turbine construction, essentially rooted on getting the same production as today’s design, while using significantly less materials, thus cutting costs substantially. But in my quest to help them raise the investment capital they need to move forward, I’m running into investors who are unsure of (more…)
In previous posts here and here I discussed a companion lawsuit to the major GE-Mitsubishi wind patent litigation in which GE and a former employee are fighting over the rights to certain wind turbine technology.
In that suit, filed in the Eastern District of California, GE accused Thomas Wilkins, an electrical engineer (more…)
Most people would agree that developing clean, renewable sources of energy is an ecologically sound proposition. The images of pristine power derived from the sun are inherently beautiful. But what if that new wind turbine is constructed of components that cannot be recycled? And what if that hydroturbine contains toxic materials that pollute (more…)
