Good News in Renewable Energy
Here’s an article that points to a further reduction in the cost of wind energy, based on collaboration between General Electric, Virginia Tech and the U.S. National Renewable Energy Laboratory that could fundamentally change how wind blades are designed, manufactured and installed.
And here’s a piece from the University of Delaware suggesting that clean energy can completely replace fossil fuels over the coming 20 years, using the right combination of renewable resources, combined with storage.
Nice to hear a bit of good news every now and then.
This appears to be very good news, however I have one concern about the design. Metal fatigue. This why wind turbine blades are not made of metal. When such blades were tried, they fatigued relatively quickly and failed. I would have concerns that the metal skeleton proposed could do the same thing. This will need careful consideration, and may necessitate partial or complete replacement of the metal components with advanced composites to ensure long life and safe operation.
