US pushing ahead on wind projects

In today's Boston Globe:


WASHINGTON - The Obama administration is boosting renewable energy on both coasts, officials said yesterday, including projects on public lands in the West and pushing for offshore wind projects in the Atlantic Ocean.
Interior Secretary Ken Salazar said his department has approved a 300-megawatt solar farm in Arizona and a 200-megawatt wind farm in Southern California. The wind farm includes 186 megawatts that would be produced on federal lands.
The projects, southwest of Phoenix and east of San Diego, respectively, are the 24th and 25th renewable energy projects approved on public lands in the past two years, Salazar said, and demonstrate that the administration’s commitment to renewable energy is paying dividends.
“Together, these projects will produce the clean energy equivalent of nearly 18 coal-fired power plants, so what’s happening here is nothing short of a renewable energy revolution,’’ Salazar said.
The Sonoran Solar Energy Project in Arizona, being developed by Florida-based NextEra Energy Resources, will generate enough electricity to power about 90,000 homes. The Tule Wind Project in California, developed by Iberdrola Renewables, the US division of a Spanish energy company, will be able to power about 65,000 homes.
While onshore projects flourish, the administration’s efforts on offshore wind have struggled. Not a single megawatt of wind power is produced offshore.
Last year, Salazar approved the Cape Wind project in Massachusetts after years of federal review, clearing the way for work to begin on the nation’s first offshore wind farm.
Yesterday, Salazar said officials are moving forward on a massive transmission project that would carry electricity produced at offshore wind farms from Virginia to New Jersey. Internet giant Google and others have pledged up to $5 billion for a network of transmission lines for offshore wind farms.
Interior’s Bureau of Ocean Energy Management is soliciting interest from developers and seeking public comments on the project, which would involve building high-voltage transmission lines along the Atlantic Coast. The line would enable up to 7,000 megawatts of wind turbine capacity to be delivered to the grid, Salazar said.

New Low Energy Snow Making Guns at Sugarbush Ski Resort.

At my favorite ski resort Sugarbush I got to see the next wave of new technology Snow Logic snow guns. Nice to see the resort testing out new "Green" technologies.

They only require 5 CFM compared to the industry standard guns that require ~ 300 CFM. They are even a huge jump better the Snow Economics HKD guns that require ~ 150 CMFs.

  I am told that the long barrel atomizes (below head seen in first picture) the water but that only the 3 up forcing jets are for air only.
I do understand that it's sweat spot is 25 degrees and above that temperature the older more air requiring guns work better.Which means the technology still needs work, but alas does not all new technology need time to evolve.

A snow gun that only requires 5 CMFs is a great energy saving product.
