This was proposed in 2009 so I imagine it is operational by now. I found this amazing document that I need to look at more, but it is a listing of all the large solar facilities maybe in the world? Anyway if you want to see cool photos go to the site because pictures are a pain.

General Description of Project

On August 10, 2009, Abengoa Solar Inc., the sole member of Mojave Solar LLC, filed an Application For Certification (AFC) for its Abengoa Mojave Solar Project. The proposed project is a nominal 250 megawatt (MW) solar electric generating facility to be located near Harper Dry Lake in an unincorporated area of San Bernardino County. The project would be located approximately halfway between Barstow, CA and Kramer Junction, CA, and is approximately nine miles northwest of Hinkley, CA.

The project will implement well-established parabolic trough technology to solar heat a heat transfer fluid (HTF). This hot HTF will generate steam in solar steam generators, which will expand through a steam turbine generator to produce electrical power from twin, independently-operable solar fields, each feeding a 125-MW power island. The sun will provide 100 percent of the power supplied to the project through solar-thermal collectors; no supplementary fossil-based energy source (like natural gas) is proposed for electrical power production.

Now that we know that humans are going to be in pretty bad shape because of climate change, let’s go back to the meditation on what could have saved us if we would have started building them sooner. Large Solar Power Plants. I am not posting any pretty pictures, just the test.

World’s largest solar plant gets U.S. OK

$6 billion project in Calif. aims to power at least 300,000 homes

msnbc.com staff and news service reports

updated 10/25/2010 6:07:03 PM ET

WASHINGTON — Calling it a major milestone, the Obama administration on Monday approved what investors say will be the world’s largest concentrated solar power plant and one that more than doubles all of U.S. solar output and can power at least 300,000 homes.

The project in the Mojave Desert near Blythe, Calif., is the sixth solar venture authorized on federal lands within the last month. All are in desert areas.

“The Blythe Solar Power Project is a major milestone in our nation’s renewable energy economy and shows that the United States intends to compete and lead in the technologies of the future,” Interior Secretary Ken Salazar said in announcing the approval.

Construction on the $6 billion plant is expected to start by the end of 2010, with production starting in 2013. Developer Solar Millennium, a company based in Germany, says the plant will generate 1,066 construction jobs and 295 permanent jobs.

The project had run into opposition by some environmentalists due to wildlife concerns.

This Is The Start Of A Solar Power Meditation – Harvesting the power of the sun

This is just such a beautiful installation. It takes up too much bandwidth to show pictures but here is a written description.

http://www.torresolenergy.com/TORRESOL/gemasolar-plant/en

Gemasolar is the first commercial-scale plant in the world to apply central tower receiver and molten salt heat storage technology. The relevance of this plant lies in its technological uniqueness, since it opens up the way for new thermosolar electrical generation technology.

Characteristics of Gemasolar:

  • Rated electrical power: 19.9 MW
  • Net electrical production expected: 110 GWh/year
  • Solar field: 2,650 heliostats on 185 hectares
  • Heat storage system: the molten salt storage tank permits independent electrical generation for up to 15 hours without any solar feed.

The prolongation of the plant’s operating time in the absence of solar radiation and the improvement in efficiency of the use of the heat from the sun makes Gemasolar’s output much higher than that which is delivered by other technologies in a facility with the same power.

The notable increase in the plant’s power efficiency guarantees electrical production for 6,500 hours a year, 1.5 to 3 times more than other renewable energies. The plant will thus supply clean, safe power to 25,000 homes and reduce atmospheric CO2 emissions by more than 30,000 tons a year.

The power generated by Gemasolar will be sent through a high-tension line to the substation of Villanueva del Rey (Andalusia, Spain), where it will be injected into the grid.

When The Oil Runs Out – Capitalism goes down with it

People are always playing out this dystopian vision of what the world will look like if there is a sharp break in the availability of fossil fuels. Most people imagine guys with guns will control their chunk of the world and abuse everyone in it for the own good. Or that we will break into semi-dead towns and farm life like 200 years ago. But, I usually say, what if it is slower than that and what if people cooperate instead of foolishly compete. Then life might look like this, which sounds kinda fun.

Ithaca Ecovillage Forges a Path to Sustainable Living

By Coralie Tripier

ITHACA, New York, Jul 16 2012 (IPS) – Ecovillage at Ithaca (EVI), located in the beautiful Finger Lakes region of upstate New York, is an intentional community of 160 people striving for greater sustainability, a better quality of life, and perhaps even a new model for urban planners the world over.

Enjoying breathtaking surroundings, residents wander around the village on pedestrian-only streets, swim in the pond, share meals in the common house, and spend a small amount of their time working together for their community.

EVI’s residents have to volunteer for two hours every week in one of the six work teams – the cooking team, the dishwashing team, the common house cleanup team, the outdoor maintenance team, the regular maintenance team, or the finance team.

“If you had a house, you would have to do that anyway, so why not do it for the broader community and make friends at the same time,” Ashley Click, a young mother and new resident at EVI, told IPS.

Predicting the Top Sustainability Stories of 2012

Last month I offered my picks for the Top Sustainability Stories of 2011. Here are my predictions for the Top Sustainability Stories of 2012. (It’s a rugged mix of bad news and good.)

Climate heats up and hides out The sheer pressure of the hard-to-escape evidence — more record-breaking temperatures, more disastrous weather events, big supply chain disruptions, ever-rising insurance payments — will drive more businesses to take global warming seriously as a business risk, even as The Economist and others blast the journalistic malpractice that leaves “climate” out of the weather disaster stories, and President Obama takes cover in an “all of the above” energy strategy.

US falls behind in solar China, Germany, Brazil — and California — continue to invest policy and capital in the new economy, while Washington remains lost in ideological shock and awe (as House republicans tell the Pentagon “you have to waste taxpayers money and make the troops less safe so we can continue to ignore both the science and the economics of climate change”). But there are surprises too: “red state” Iowa has decided that exporting $6b/year to buy fossil fuel from unfriendly nations might not be the most “conservative” plan, and is investing government money to reduce that balance of payments deficit!

EPA battle royal The right’s war on the EPA (and on regulation in general) will continue, and in fact heat up as campaign fodder. Little noticed: 191 house votes attacking the EPA in 2011. Expect this battle to continue into 2013 (depending on how the elections turn out). But there’s good news too.

More on Grand Staircase Escalante National Monument

Author: Jeanna Thomas  |  Category: Behind the Scenes, Caroline Raville, Environment, Landscapes, Season Two, TAL on PBS

This is the third in a series of blogs written by This American Land host Caroline Raville on her recent experience shooting  a story for season two at Grand Staircase Escalante National Monument. Read the first two blogs in this series, Grand Staircase Escalante National Monument in Season Two and Host Caroline Raville on Grand Staircase Escalante National Monument.

And now we are crossing over the mighty Paria River,” Dr. Titus observes.

I look down below. I see dirt and a puddle. Dr. Titus and Scott Richardson are grinning at my incredulous look as we bump along the pockmarked road. Apparently, this crack in the mud does become a river occasionally. Escalante experiences extreme weather ranging from boiling, fly-infested summers to frozen winters. Still, the evidence before me seems to suggest that this place is in a constant state of dry heat.

We drive deeper into the monument, and the paleontologists decide to take a quick detour promising spectacular views. After a steep climb with some seriously wicked turns, we find ourselves looking down on a valley littered in rock formations. There are the tar colored hills which look like a blackened sand dune. Further up, rust tinted rocks roll in the shape of a dragon’s back. And above are the whitewashed peaks dotted with green scrub brush. These layers are a physical timeline that helps scientists to establish the changes in habitat that occurred here. From ocean floor to swampland to the now arid desert, Escalante has experienced some major changes during its existence due to plate tectonics and the resulting mountain building.

OH and some housekeeping issue. The below websites asked for “links”. So by posting them here I believe we are linked. I have never used either so these are not endorsements, but they seem legitimate. As with all of the internet, buyer beware.

Oil Stocks By Mike Nadel – Good advice from a good guy

I do not normally boost someone else’s net contributions just because I think the author is cool. Had he not written about oil stocks I probably wouldn’t either, but it is the summer. Because I was getting alittle burnt out on all the serious blogging I have done for 5 years, I gave myself permission to post whatever I wanted too and boringly I have stuck to energy conservation, the residential market and all things environmental. So today is a really “what the hell” kinda day. Enjoy.

Time To Slide Into Oil Stocks

??By Mike Nadel

The last time I filled my car’s tank, I paid less than $3 a gallon. As my wife will attest, I was more than a little giddy. “Two-ninety-seven!?!? You gotta be kidding me!!! This is incredible!!!” Hey, we all have to find life’s little thrills wherever we can, right?

The price of crude oil, the source of gasoline, is determined by numerous factors: supply and demand, the Middle East unrest, natural and unnatural disasters, Wall Street speculators, economies in the U.S., Europe and emerging markets, etc.

Crude oil reached $110 per barrel on February 24 and was still over $100 per barrel two months later. It has been on a fairly steady decline since, hitting $80 per barrel on June 22 – its lowest level in two years – before rebounding into the mid-80s. So what’s next?

I certainly am no oil-price-trend expert… and even if I were, I wouldn’t listen to myself. Wasn’t it just a few months ago that alleged experts were predicting $5 gas by Memorial Day and maybe even $6 by the Fourth of July? Still, when it comes to forecasting oil prices, “Up” usually is a reasonable guess – especially after it has been down.

Is Tidal Energy Coming – According to this the answer is yes

Tapping The Source: The Power Of The Oceans

Posted by Big Gav in , , , , , ,

Last year I came across the story of Dutch company Kema and their energy island idea – basically a variant on the usual pumped hydro energy storage concept where water is pumped out of a space below sea level then allowed to flow back in, generating power as it does. The “island” uses wind power to pump water out of the enclosed area. An obvious extension to this idea would be to harness ocean energy as well – letting wave and/or tidal power supplement the output of the wind turbines. An attraction of this concept is that it potentially allows a large amount of new energy storage to be brought online – and this storage would be along the world’s coastlines, where most of the population lives.


Another form of energy island has been in the news recently, this one a substantially more ambitious proposal which envisions artificial islands to collect wind, wave, ocean current and solar power in the tropics, along with a more unusual energy source – harnessing the difference in water temperatures between the warm surface and the cold depths using a technique called OTEC (Ocean Thermal Energy Conversion). These islands are being proposed by architects Dominic Michaelis and his son Alex Michaelin as a response to Richard Branson’s Virgin Earth Challenge, which offers $25 million in prizes for innovative solutions for combating global warming.

While the practicality of these particular proposals has yet to be put to the test, the various forms of ocean power are probably the most overlooked of the big 6 renewable energy sources (along with solar, wind, geothermal, biomass and hydro).

India Must Somehow Get Power For 4 Hundred Million People – Is the answer solar

Posted on by
Reply

They have more people without electricity then there are in the United States. MAN! So solar might seem inadequate but I do not think so. I believe if China keeps pumping out the panels.

Written by Varun Mittal | 02 July 2012

India’s per capita consumption of electricity per is around 481 units or one-fifth of world average of 2596 units. Compare it to 900 units per month consumption of electricity in US. Such a low electricity use in India adds to the challenge of development because in order for India to be energy secure, the country needs to first match its supply of power with the demand. In addition, it must add the capacity year on year with respect to the gross domestic product (GDP) growth rate, power being a primary ingredient in economic development.

Gap between supply and demand of power

LOADS DEMAND AVAILABILITY DEFICIT
BASE LOAD 861,591 (MU) 788,355 MU 8.5%
PEAK LOAD 122 GW 110 GW 9.8%

Source: CEA report, 2011

Solar power in the renewable energy mix

India needs to sustain an 8% to 10% economic growth rate, over the next 25 years, and it needs, at the very least, to increase its primary energy supply. Fortunately there is an abundance of solar energy across India. About 5000 trillion kWh per year energy is incident over India’s land area with most parts receiving 4-7 kWh per square mile per day. The annual average global solar radiation on horizontal surfaces, incident over India is about 5.5 kWh per square metre per day or 1650 Kwh per square metre per year.

Fortunately there is an abundance of solar energy across India.

Based on such promising solar energy potential across India, the government of India rolled out

Based on such promising solar energy potential across India, the government of India rolled out the central policy “Jawaharlal Nehru National Solar Mission: JNNSM” on 23 November, 2009 to add 20,000MW grid-connected solar power capacity, which is 27.62% in grid-connected renewable power capacity by 2022.  However, along with the central policy, 3 states (Rajasthan, Gujarat, and Karnataka) have come up with their state solar policies that are independent or concurrent to central policy while other states are planning their solar policies such that the total contribution of solar will be much higher in the renewable power mix. Therefore, the percentage of renewable power in the cumulative grid-connected power capacity will be increased.

Healthcare Upheld – But that is not what I am going to post about

It has been the shipping industry’s wet dream for a hundred years, Wind Power. They dream back to the days when the only costs for shipping was the ship and port fees. I do not know if this is the system that will catch on but it is pretty cool nonetheless.

Wind-Powered Cargo Ships Make a Comeback

February 28, 2011 By

Sailing ships once carried much of the world’s cargo across the seas, until canvas sheets were replaced by low-grade “bunker” oil. Now it appears that wind power is about to make a comeback, in the form of rigid “sails” that double as solar panels. The patent-pending technology, called the Aquarius Solar and Wind Marine Power System, is being developed by a company called Eco Marine Power. The dream of a high tech, sustainable energy cargo ship has been percolating for a number of years now, but it hasn’t caught on in a big way, so let’s see if this new system is The One.

Wind Power for Cargo Ships

At first blush, wind power for today’s ultra-huge cargo ships looks like a nice idea, but just not possible. The scale alone makes it seem impractical. However, that hasn’t stopped anyone from trying. In recent years a German company has come up with a parachute-like design for cargo ships that includes sails the size of football fields, and a British company has developed a more traditionally styled, rigging-free sail system for smaller cargo ships.
