Enormous blades could lead to more offshore energy in US

Posted on Leave a commentPosted in Technology, Wind Energy

A new design for gigantic blades longer than two football fields could help bring offshore 50-megawatt (MW) wind turbines to the United States and the world. Sandia National Laboratories’ research on the extreme-scale Segmented Ultralight Morphing Rotor (SUMR) is funded by the Department of Energy’s (DOE) Advanced Research Projects Agency-Energy program. The challenge: Design a […]

Economic Case for Wind, Solar Energy in Africa

Posted on Leave a commentPosted in Solar Energy, Technology

To meet skyrocketing demand for electricity, African countries may have to triple their energy output by 2030. While hydropower and fossil fuel power plants are favored approaches in some quarters, a new assessment by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has found that wind and solar can be economically and environmentally […]
