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.

Australia poised to take the lead in solar energy market

– July 16, 2012

Yingli Green Energy notes the solar energy potential of the country

Over the past decade, Australia has shown modest support for alternative energy. In recent years, this support has been growing at a rapid pace, with the country now showing major interest in solar energy. Because of Australia’s exposure to solar radiation, it is one of the most attractive locations in terms of a solar energy market. Yingli Green Energy, a Chinese solar panel manufacturer, believes that the potential for solar energy in Australia is so high that it may become the leader of the photovoltaic mass market by the end of the year.

Australia could benefit from Chinese manufactured solar technologies

Solar energy has been growing in strength all over the world. Demand for solar energy systems is growing amongst consumers who wish to see savings of their energy bills as well as help the environment. As demand for solar energy systems rises, so too does the supply of these energy systems. China has played a large role in the growing availability of solar energy systems. The country has thrown its manufacturing might behind the production of solar panels and other technologies, inundating the mass market with products that are driving down the price of solar energy systems.

Company expects solar energy market prospects to be extraordinary

Yingli Green Energy is one of the three largest solar panel manufacturers in China, as well as the rest of the world. Though the company has a small presence in Australia, it claims that the country could become a world leader in terms of solar energy in the coming years. The company expects Australia to see major progress in the solar energy market by the end of the year, with its prospects becoming “quite extraordinary” in 2014 and 2015.

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.

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

Posted on by

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%

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.

Longterm Storage Is Not An Issue – It never has been for renewable energy

This is actually part of a lecture that I give to college students called the Myths of Global Warming. The point of it is that Global Warming is indeed happening and at an accelerated pace. The point is that there have been myths erected like barricades that defend the use of fossil fuels. Here is a high tech version.

Super Hot Salt: The Newest Energy Storage Innovation?

Policymakers and energy industry experts often talk about clean energy as though it isn’t reliable. In fact, while an MIT study recently found the existing grid would probably be up to the challenge of absorbing clean energy, intermittency does present a real challenge that renewables must address to get to high levels of penetration.

But BrightSource Energy, a major player in the market for concentrating solar power, or CSP, recently announced the installation of new thermal energy storage technology at three of its planned power plants in California. This thermal energy storage technology will go a long way toward solving the intermittency problem for concentrating solar power. BrightSource’s announcement demonstrates that we can in fact get reliable baseload power from the sun [or, even better, load-following power].

The thermal energy storage systems, built using SolarPLUS technology, work by using hundreds of parabolic mirrors to concentrate the rays of the sun on a tank of molten salts, heating the salts to several hundred degrees above the boiling point of water. The superheated salt is then stored in a giant insulated container until the power plant needs to add additional output, at which point it can use the heat stored in the molten salt to boil water to create steam to drive its turbines.

The Ivanpah Solar Project Named 2012 Energy Project of the Year

April 24, 2012

Project recognized for its innovative approach, job creation and scale of clean energy production

(LOS ANGELES, Calif.) April 24, 2012 – NRG Energy, Google, BrightSource Energy and EPC partner Bechtel announced that the Ivanpah Solar Electric Generating System (Ivanpah SEGS) received the 2012 Energy Project of the Year Award by the USC CMAA Green Symposium. Ivanpah SEGS in California’s Mojave Desert is currently the world’s largest concentrating solar power (CSP) plant under construction. When completed, it will nearly double the amount of solar thermal electricity produced in the US.

“The sheer magnitude of the Ivanpah project is reinforcing California’s position as the leader of renewable energy in the United States,” said Caroline Fletcher, USC Green Symposium Co-Chair. “The project has demonstrated an innovative approach to partnerships and is significantly contributing to job creation in the region. We’re very pleased to honor this important project with our 2012 Energy Project of the Year Award.”

“Ivanpah is a flagship project, widely recognized for its environmentally-responsible design, and lauded for its role in helping to grow Southern California’s High Desert economy,” said Joe Desmond, SVP of Government Relations and Communications, BrightSource Energy. “We look forward to completing this important solar power facility and help California meet its economic and clean energy goals.”

“We are pleased to be a part of this award-winning project. The innovation applied to the engineering and construction of Ivanpah will help advance the renewable energy industry and make solar energy a viable option for more people,” said Jim Ivany, president of renewable power at Bechtel.

Largest tidal arrays in the world to be built in Scotland

15 June 12

Scotland will see the world’s largest tidal arrays constructed off its coast, as the first large-scale rollout of tidal energy generation.

A trial with one 30m turbine, the HS1000, anchored to the ocean floor in a fast-flowing channel near the Orkney Islands, raised one megawatt of electricity — enough to power around 500 homes. Now, Scottish Power is planning on building two farms of turbines off the Scottish coast.

The project at the Sound of Islay should hopefully generate 10MW, and then the later project off Duncansby Head (the most northeasterly point of Scotland) should generate around 95MW. While individual turbines have been trialled across the world, the arrays will be the largest of their kind, with local communities having their power provided by renewable tidal sources.

The turbines — built by Andritz Hydro Hammerfest, a Norwegian firm — represent a tricky engineering challenge. Considerations for wild plants and fish means that the blades can’t move too fast, and the turbines must be located in areas where there is a reliably fast current travelling at at least 2.5m/s (such as the Sound of Islay, a narrow passage between the Scottish mainland and the island of Jura).

Not much to say about this. As the founding father’s said, “We hold these truths to be self evident”.

 

http://www.savingpower.com/three-new-fun-renewably-powered-gadgets-to-get-you-saving-energy/

There seems to be no end of interesting and innovative renewably-powered gadgets coming on the market these days, some more affordable and useful than others. But they all have one thing in common: making it easier for you to power-up your various portable electronic devices on the go with clean energy, like solar energy, kinetic energy, and even doggie-powered energy!

Take the Scosche solBAT II for instance. It’s a solar charger that hooks up to most portable devices using a USB connection. It has a 1500mAh capacity battery with a 5-volt output. You can hook it to your backpack, hang it from your car window with a suction mount, or just put it on your desk. Wherever you put it, just be sure to leave it where it will get direct sunlight. You can charge up the onboard battery within about five hours (after an initial charge that takes 4-5 days). And the best part is that it is only $30.

Then there’s the new Neon Green solar bag. Now, we know that there are a ton of solar bags around these days, but this company has put together a wide range of styles and shapes so that there’s something for almost any renewable energy enthusiast looking for a new bag. From the Piggy Back Soular Back-Up Pack (attach it to your existing backpack), to the full-sized Centurian backpack, to the Big Piggy (for powering up gadgets), they’ve got all kinds of options.
