Activation of the zeroemission solar energy system is major step for Ironwood in meeting the CDCRs energy management goals as well as Governor Schwarzeneggers Executive Order Over years of production, the system will offset 31,627,817 lbs of carbon dioxide, the equivalent of powering 3,377 homes for one year..

The order mandates that State agencies evaluate the merits of using clean and renewable onsite energy generation technologies in all new building or large renovation projects, and take measures to reduce gridbased energy purchases for stateowned buildings by percent by through costeffective efficiency measures and distributed generation technologies. It will produce 35,981,589 kWh over years, the equivalent of removing 3,100 cars from the road. Were helping to clean the air, and simultaneously relieve some of the ever increasing pressure on the electric utility grid, said CDCRs Deborah Hysen, Chief Deputy Secretary, Facilities, Planning and Construction.

In SunEdison activated MW solar power system at Chuckawalla has produced more than million kWh since commercial activation.

Over twenty years of operation, the Ironwood system is expected to produce more than million kWh since commercial activation.

the skeptic in me will be happy if we can finally break ground on some new plants. We do need to add lot more transmission capacity.

the skeptic in me will be happy if we can finally break ground on some new plants. am especially happy they are building it here in the States and not sending it off to China as some of the other designs call for. We see Nevada as one of the earlier posts indicated we need to add lot more transmission capacity. We looked at locations in California, Phoenix andhere. Taking the fiveyear view, we would like to build lot of powerplants in the Southwest so we asked, Where is the best location? Whatare the transportation options?

We do need to add lot more transmission capacity. couldnt imagine they would spend the amount of money needed to build factory this large and not have good idea they were going to many more contracts. We looked at locations in California, Phoenix andhere. We see Nevada as one of the best markets for solarpower, says ODonnell. was very skeptical of Ausras plans and design when first read about it but with all the interest from major players they must be doing something right.

It is Europes first commercially operating power station using the Suns energy this way and at the moment its operator, Solucar, proudly claims that it generates Megawatts MW of electricity without emitting single puff of greenhouse gas. But our reward was the cool breeze at the top of the tower Letting off steam one of the gurus of solar thermal power, Michael Geyer, an international director of the energy giant Abengoa, which owns the plant.

It was like being in sauna and for the last stages the metal rungs of the ladders were scalding. had trouble working it out. HOW THE SOLAR TOWER WORKS In fact, as we found out when we got closer, the rays of sunlight reflected by field of huge mirrors are so intense they illuminate the water vapour and hanging in the air. The effect is to give the whole place glow even an aura and if youre concerned about climate change that well be deserved.

It is Europes first commercially operating power station using the Suns energy this way and at the moment its operator, Solucar, proudly claims that it generates Megawatts MW of electricity without emitting single puff of greenhouse gas. concrete tower storeys high stood bathed in intense white light, totally bizarre image in the depths of the Andalusian countryside. But our reward was the cool breeze at the top of the tower.

It was probably the heat that did it, but found myself making the long journey up to the very top to the heart of the solar inferno. It is Europes first commercially operating power station using the Suns energy this way and at the moment its operator, Solucar, proudly claims that it generates Megawatts MW of electricity without emitting single puff of greenhouse gas. We could soon feel the heat, despite thick insulation around the boiler. What happens when the goes down?

Is it true that this power is three times more expensive than power from conventional sources? Yes, but prices will fall, as they have with wind power, as the technologies develop. They track the and direct its rays to heat exchanger receiver at the top of the tower. What happens when the goes down? Enough heat can be stored in the form of steam to allow generation after dark only for an hour but maybe longer in future.

The land area needed for coal and solar is probably equivalent. Yes, even uranium deposits are limited. noahhoward, on 42Saving the planet by paving it with mirrors, brilliant. Sure it is green, but really, just use nuclear until the of solar energy goes down. Also new grid of DC lines would need to be some interest free loans or something… Thats better use of our uranium then shooting it at Iraqis. The sheep dont want to hear that.

Thats nearly 60,000 per household powered. Good catch. steelersfan7roe, on 17Wish could digg it twice. TJ11240, on 12No energy source can provide 100 of our needs, not even coal or nuclear. think this is great move. Fusion in everyones homes…AndyStitzer, on 81Also, where does the power for these 70,000 homes come from at night. Flagstaff has more clear nights than anywhere in the world, thus we have one of the few things where you lot more out of what you put in.

Obviously their plan is on huge scale, however it is pretty clear that even if only part of this infrastructure was constructed it would help clean up our energy …TJ11240, on 01Thank you. We should consider this way also. godofblog, on 00Our powerful solar floodlight includes three adjustable lamps, each with three white LEDs to provide improved light output. California recently ran out of power because they hadnt built any plants. She paid in one month. Its the nutjob environmentalist who fear nuclear that are stopping us.

This method is similar to the way that we currently use to store trillions of cubic feet of natural gas. Props to APS. plundstedt, on 82Digg me downcawpin, on 11Dont count on it. Its little hypocritical not to give solar the same headstart. Its parabolic mirrors concentrating sunlight onto tubes of oil, to superheat it to make steam. Nothing to do with bandwidth but the electricity the server uses to stay up? dunno, maybe Im the crazy one. barfooz, on 24WhooooooshThere, in the sky! Is it bird? Is it plane? No its the joke! And it just went over your head! 471776, on 01Okay, sorry.

can imagine it nowConsumer Why have my rates gone up? Has the price of sunshine gone up?Electric Company 2010 was pretty cloudy year, and the forecast for next year is just as bleak.alanflores, on 55How the weather in Gary, Indiana? NoCt1, on 02Not good. cawpin, on 01WTF? He makes very valid and probable statement. 0crabby0, on 14So you use part of the solution, unless of course battery technology improves. ausfahrt, on 122You know bet they never thought of what to do during the night.
