Discusses the recent news that renewable energy (including hydro as well) now supplies more electricity to the US grid than does nuclear power. The post then goes on to list some large solar and wind projects in advanced stages of the development pipeline as a reason for being optimistic that the solar and wind side of the renewables is rapidly growing in scale.
This post takes a look at hydro power potential in the US, which is significant. For example, Oak Ridge National Laboratory has estimated that there is more than 12GW of untapped capacity at existing dams across the US; this is in part due to the fact that only 3% of existing dams generate electricity. Furthermore a 2006 DOE report noted that in every region realistic increases in generation capacity ranged from a minimum of 50% to well over 100%, which represents a lot of potential additional power. Large dams have serious environmental issues, disrupting Salmon runs for example, but a lot more power can be generated from existing dams and from less disruptive run of the river hydro.
A new study that is sure to create some controversy proposes that the world can provide for all of its energy needs, including electric, transportation, heating/cooling energy needs using only wind, water, and solar power by 2030.
Stephen Hinton, provides a compilation of professionals that will see growth as the US economy goes green. He predicts that those in STEM professions (Science, Technology, Engineering and Mathematics) will experience the most job security.
The Natural Resources Defense Council (NRDC) recently announced their list of the greenest cities in the United States and have released their findings on a new web site, called Smarter Cities. The survey includes all cities in the United States with populations larger than 50,000. Smarter Cities is considered to be one of the nation’s most comprehensive and robust database of U.S. urban progress toward sustainability. Seattle ranked number one and San Francisco ranked number 2 among the 67 large cities that were evaluated. Madison, Wisconsin placed firstand Santa Rosa, California came in second among the 176 medium cities that were surveyed. Among the 402 cities that were evaluated, Bellingham, Washington came in first place and Mountain View, California came in second.
