Alaska's alternative energy revolution will take a new twist this summer when 15 turbines spin to life over a trio of Southwest Alaska villages, in one of the most notable wind projects ever to reach the Bush.
Like so much heavy equipment in Southwest Alaska, the turbines are old-school hand-me-downs imported from the Lower 48 -- in this case, the California desert. They seem small and stodgy by today's standards, resembling Kansas farm ornaments with four-legged bases and lattice-work sides. But at 12-stories tall, they'll tower over tiny Kwigillingok, Kongiganak and Tuntutuliak, home to about 1,200 residents total.
They're a perfect fit for the small communities, experts said. And refurbished though they are, the turbines are part of a decidedly high-tech project that includes online meters residents can use to monitor electric use from home computers and electric heaters that automatically fire up when extra wind blows.
People are ready for relief from high costs in the Yup'ik villages near the Kuskokwim River mouth, where the diesel fuel that provides power and heat is barged up the coast at great expense, said William Igkurak, longtime manager of the local power company.

WASHINGTON—As U.S. lawmakers promote natural gas as a way to reduce air pollution, a scientific study published this week questions the benefits of the fuel when used to power vehicles and generate electricity.
The study authors said methane leaks from the production and transportation of natural gas should be studied in greater detail before the U.S. adopts any major policy shifts.
The study, co-written by scientists at several universities and the environmental group Environmental Defense Fund, wades into an increasingly murky area of energy research. In it, scientists said the production of natural gas results in methane leaking into the atmosphere, which contributes to climate change and limits the environmental benefits of natural gas. Methane, the primary component in natural gas, is more potent than carbon dioxide as a greenhouse gas but decomposes more quickly in the atmosphere.
The research comes at a time when President Obama and other U.S. lawmakers are hailing natural gas as a fuel of the future, capable of replacing coal in power plants and gasoline in cars. That is because it is thought to be better for the environment and is produced in abundance in the U.S.

Pursuing a portfolio of renewable power sources such as solar, biomass and wind power to satisfy Virginia's energy appetite through 2035 would create tens of thousands more jobs than relying on either coal or natural gas, a George Mason University study concludes.
The study released Wednesday was prepared for Virginia Conservation Network, a coalition of environmental groups and proponents of renewable energy sources over fossil fuels.
George Mason's Center For Regional Analysis based the study on the 2010 Virginia Energy Plan, which projected a need for an additional 19,448 megawatts of demand over the next 25 years. Half of that demand can be met through biomass, solar and wind, offshore and onshore, the study concludes.
Nathan Lott, executive director of the Conservation Network, said the study illustrates that renewable energy can be competitive with fossil fuels. "This is important for regulators and utilities that must plan today for a safe, reliable electricity system 20 and 30 years into the future," he said.

BERKELEY, Calif., April 27 (UPI) -- Ocean salinity is being affected by global warming, and current models underestimate the change to the globe's water cycle, an Australian scientist says.
The water cycle -- the worldwide phenomenon of rainwater falling to the surface, evaporating back into the air and falling again as rain -- is changing, with the wetter parts of the world getting wetter and the drier parts drier, researchers report in Science magazine.
This is confirmed by the fact that saltier parts of the ocean are getting saltier and the fresher parts are getting fresher, they said.
"Salinity shifts in the ocean confirm climate and the global water cycle have changed," said Paul Durack of the University of Tasmania, who is now a post-doctoral fellow at Lawrence Livermore Laboratory in California.

PORTLAND, Maine -- Maine regulators have put three utilities on the path to distribute electricity harnessed from tides at the nation's eastern tip, a key milestone in a bid to turn the natural rise and fall of ocean levels into power.
The Maine Public Utilities Commission set terms for a contract that would be in place for 20 years. The regulators also directed the three utilities to negotiate with Ocean Renewable Power Co. to put electricity onto the grid this summer, the first long-term power purchase agreements for tidal energy in the United States.
"It's a landmark in the commercialization of tidal energy in the U.S.," said Chris Sauer, president and CEO of the Portland-based company.
Ocean Renewable intends to install its first underwater turbine unit this summer on Cobscook Bay under a demonstration project.

In a northwestern corner of India, rows of steel and glass are rising from the ground to form what will be one of the largest solar power plants in Asia. The 250-megawatt project is the first in India for Silicon Valley-based Areva Solar, which is benefiting from an aggressive plan by the Indian government to boost solar energy generation to help reduce the country’s greenhouse gas emissions.
Areva engineers solar power plants that use flat mirrors to concentrate sunlight onto water-filled tubes to produce steam, which is then piped to run a turbine to generate electricity. This process is called concentrating solar thermal technology, and it’s being used in different configurations to build solar farms in the United States, particularly in states such as California and Arizona.
The company will complete the project in two phases, with the first 125 megawatts to come online in May 2013, said Jayesh Goyal, the company’s global vice president of sales. The second phase will start delivering power in late 2014 or early 2015.
“India is a market with a high electricity demand and a favorable regime for renewable energy,” Goyal said.

Washington, D.C. - infoZine - India’s ambitious national solar program has catalyzed rapid growth in the solar market, driving prices for solar energy to impressive lows and demonstrating how government policy can stimulate clean energy markets, according to a report released today by the Natural Resources Defense Council (NRDC) and the Council on Energy, Environment and Water (CEEW).
In only two years, competitive bidding under India’s National Solar Mission drove prices for grid-connected solar energy to nearly the price of electricity from fossil fuels, at Rs. 7.49/kWh ($0.15/kWh). During that same period, cumulative installed solar capacity in India surged from 17.8 MW to over 500 MW, as discussed in “Laying the Foundation for a Bright Future: Assessing Progress Under Phase 1 of India’s National Solar Mission.”
“As the world’s second-fastest growing economy, India has sparked a powerful solar market in only two years,” said Anjali Jaiswal, Senior Attorney for the Natural Resources Defense Council’s India Initiative. “While the National Solar Mission still faces significant hurdles, India has already made important strides to attract new domestic and international players into the market, and lower the price of solar energy faster than most anticipated.”

Michigan electricity providers are making good progress toward meeting the state’s 2015 renewable-energy mandate, mainly because of a sharp drop in wind-power generation costs, a recent state Public Service Commission report found.
The commission also says the cost of renewables is lower than the projected cost of producing electricity from a new coal-fired plant.
Spokesmen for DTE Energy and Consumers Energy, the state’s two largest electric utilities, wouldn’t comment on whether the utilities agreed with the commission’s cost comparisons.
“Wind is the cheapest resource to bring large amounts of renewable energy online,” said Julie Baldwin, manager of the commission’s renewable energy section. “It’s hard for other sources to be competitive.”

And, ultimately, it’s the answer. Eventually the capacity of solar cells will increase, the cost to manufacture them will go down, and battery storage will improve such that sunlight collected on a sunny day can be used during a cloudy week.
But when?
Perhaps sooner than one might think. According to the giant consulting firm McKinsey & Company, solar capacity globally will soar as costs fall by an average of 10 percent a year through 2020. It should become cost competitive with fossil fuels in a decade, the report says.
“The pace of cost reductions has been staggering. When companies are building new energy infrastructure, solar will be a competitive option within this decade,” report author Krister Aanesen said in a news release. “It will be cost comparable to peaking plant within two to three years in some countries and comparable with base load plants by the end of the decade.”
