Proposal to harness wind power off Mendocino coast worries fishing industry

By Maddalena Jackson – mjackson@sacbee.com 
 
Oil companies, some politicians and commuters paying $4 for a gallon of gas might look at California’s coast and think of crude oil pooled below the seafloor.

The state’s North Coast, however, holds promise of another energy bounty.

In less time than it would take to fire up new offshore oil drills, waters off our coast could host floating wind turbines and undulating buoys driven by waves, producing abundant electricity for a power-thirsty state.

Energy from Offshore Wind

Energy from Offshore Wind

Energy from Offshore Wind

Technology Conference

Abstract This paper provides an overview of the nascent offshore wind energy industry including a status of the commercial offshore industry and the
technologies that will be needed for full market development. It provides a perspective on the status of the critical environmental and regulatory issues
for offshore wind and how they are affecting the formation of the U.S. industry. The rationale provided describes why offshore wind has the potential to
become a major component of the national electric energy supply. Future projections show this potential could result in over $100 billion of revenue to the
offshore industry over the next 30 years in the construction and operation of offshore wind turbines and the infrastructure needed to support them. The
paper covers technical issues and design challenges needed to achieve economic competitiveness for near term deployments in shallow water below 30-m depth.
It also examines the requirements for future technologies needed to deploy systems in deeper water beyond the current depth limits. Although most studies
to date indicate very low impacts to the environment, regulatory and environmental barriers have hindered the first offshore wind projects in the United
States. A summary of these issues is given.

Introduction Over the past two decades, on-shore wind energy technology has seen a ten-fold reduction in cost and is now competitive with fossil and
nuclear fuels for electric power generation in many areas of the United States.

U.S. blows by Germany in wind-energy output

By Steve Gelsi, MarketWatch
Last update: 12:26 p.m. EDT July 22, 2008
NEW YORK (MarketWatch) – The U.S. in July surpassed Germany as the world’s largest wind-energy producer, as the business of harnessing electricity from giant turbines continues to pick up momentum on several fronts.
“Wind is now a mainstream power source – it’s not just an alternative energy,” said Randall Swisher, executive director of the American Wind Energy Association, a lobbying group.

$4.93 billion approval brings the power of wind to North Texas

Hello, beautiful.

Hello, beautiful.

According to Texas Public Utility Commissioner Paul Hudson, Texas will soon produce more wind megawatts than the next 14 highest wind-producing states combined.

Large Scale Oceanic Wind Power

Off shore wind farm locations found via satellite

20 percent is not bad, but where else could large scale wind farms be built? A Publication in the current issue of Geophysical Research Letters by a team of scientists from NASA’s JPL uses satellite data to measure the surface stresses over the oceans. Recent technological advances have made floating wind farms possible, but the key is putting them in the right locations. The article examined eight years of data from the QuikSCAT data to determine the energy distribution over the world’s ocean. The research identified three causes of regional variations in the power carried by the winds: “land mass deflection of the surface flow, the gap wind channeled by land topography, and surface stress variation produced by atmospheric buoyancy driven by ocean front.”

From the data, the researchers found that high wind areas over the ocean could be used to harness between 500 and 800 W/m2. That’s less than solar power can generate under ideal conditions, which is 1000 W/m2, although ideal solar conditions are rare. Given the higher efficiency of wind power over solar, however, the cost per kWh of electricity produced would be less.

Transmission bottleneck could stall green energy -NCJ

Too much power?
Transmission bottleneck could stall green energy

by Heidi Walters

 

In fact, the renewable energy potential in Humboldt County is so high there could be a surplus of renewable energy far beyond the demands of our snail-crawl population growth. According to the “energy element” section of Humboldt County’s draft General Plan, prepared by Schatz Energy Research Center, the wind potential for Humboldt County is 400 megawatts and the wave potential is 500-1,000 megawatts. Some estimates reach even higher. In the winter time, our peak energy usage period, Humboldt County consumes only 150-160 megawatts. Wind and wave offer the largest renewable potential, followed by biomass, hydro, solar and others.

Much of that renewable development is speculative at this point, particularly on the wave front. But to those who want to find a way to boost our local economy, the prospects are tantalizing: We could sell this extra green power to the less geographically fortunate, those California towns and cities still struggling to do their part to help the state meet its Renewable Portfolio Standard — a mandate that the state’s renewable generation must equal 20 percent of power sales by 2010. And the green boom could draw an influx of entrepreneurs to set up shop in Humboldt County.

But for the would-be profiteers from the green-power goodness, there’s the little problem of our area’s electrical transmission capacity. It’s small. Four lines connect Humboldt County to the outer world, and Pacific Gas & Electric’s main grid system: two lines between here and PG&E’s interconnect station at Cottonwood (near Redding), a line from Bridgeville-Garberville and a line from Trinity County.

“The sum total of the instantaneous power that can be imported or exported, on demand, is 70 megawatts,” says Boyd.

Bear River Wind project – Shell WindEnergy

Posted in Uncategorized with tags , , , , , , , , , , , , , , , , on May 29, 2008 by highboldtage

Bear River Wind project – Shell WindEnergy

The proposed Bear River project is located in northern California, about 6 miles south of the town of Ferndale, in Humboldt County. The project is located on private property along Bear River Ridge.

 

The project will likely be comprised of approximately 25 to 35 two-megawatt turbines, which will be sited along the ridge in a line about six miles- long.

Shell Wind Energy has been conducting wind studies, avian studies and other technical evaluations at the site since 2004. Several more years of studies are required before a final investment decision is reached.

Bear River Ridge is well suited for wind farm development because of the strong steady winds and open landscape. The current land use is primarily grazing, which has been proven to be very compatible with wind projects.

Shell is looking forward to continuing work with the Federal, State and County officials and local communities to develop this project, and to becoming a contributing member of the community.
