Cleantech's solar array will be seven times larger than the next closest rival

Portugal announced in April that it was home to one of the world's largest solar arrays. The 150 acre, 11-megawatt (MW) solar plant was built by Catavento and PowerLight Corporation and is capable of powering 8,000 homes in Serpa.

Cleantech America LLC., a San Francisco-based company, plans to build a solar farm that would far eclipse the one built in Portugal. The new 80 MW farm, known as the Kings River Conservation District Community Choice Solar Farm, will be situated on 640 acres of land and is scheduled to be completed by 2011.

"We're pretty confident that solar farms on this scale are going to have an industry-changing impact," said Cleantech CEO Bill Barnes. "We think it's the wave of the future. This scale of project, I think, creates a tipping point for renewable energy."

"We think the impact for it will be similar to the impact of the computer chip," Barnes continued. "So too will economies of scale like the Community Choice farm drive down the cost of solar."

Cleantech estimates that the energy generated by the solar array will be enough to power 20,000 homes.

there was a case (in washington I believe?) where a research reactor, or a nuclear plant... something nuclear... was operating, and needed outside power to expand. The cheapest thing was to add a coal power generator to the facility, but because it was a nuclear facility, there are radiation release limits. In short, the coal plant had to be outside the bounds of the nuclear facility, because burning coal releases more radiation into the environment than a whole nuclear facility does....

Almost all clean coal initiatives were killed when president Bush let the industry expand without regards to clean-coal measures that were passed. It was supposed to be that if a coal-fired power plant wanted to expand,they had to reduce emissions, and the only real way to do it on a large scale was clean-coal technology.

Much the same was allowed for the oil refineries by president Bush. Money given to expand, and then environmental measures pulled back when the industry whines.

Same thing happened with the auto industry between clinton and bush. For every model that can run on ethanol or a hybrid- they can release more gas-guzzling, polluting models.
Funny thing- there isn't ethanol to be had; so we import corn to supplement our cattle feed (which is going to ethanol), burn coal to make ethanol (which is technically an "energy carrier" as we produce it rather than draw [or refine] it from another substance). Thats why the price for dairy is going up.
Ethanol also had less equivalent energy per gallon compared to gasoline, makes blends burn faster. So everyone is paying more for up to 10% blends at the pump for less mileage (due to less energy and faster burning rates) and less efficiency. But those are the "reasons" why the ignorant public won't adopt electric cars.... or pursue bio-diesel (esp the kind made from algae, not soybeans)

You're talking about the Hanford Reactors near the Tri-cities in eastern Washington State. They are currently the only breeder reactors online in the US last I heard, and also it is the only place were glassification of spent atomic fuel can be done, which turns dangerous radioactive waste into harmless material, but for a huge energy cost. And yeah, I know what you are talking about. It is ironic, but all coal plants, even the "clean" ones, produce more radioactives (in the form of radium) than nuclear, yet everyone freaks out if you talk about nuclear power plants. It's like that initiative they had awhile ago about nuking food products (using gamma rays) like meat before sending them out from processing plants so as to stop E. coli and other diseases. People heard the word "radiation" and freaked, yet they don't understand at all that radiation only lasts as long as the emitter is on. Radiation and radioactive are completely different concepts, and radiation can't make something radioactive. So, then we get horrible bacterial outbreaks every other year that kill a handful of people and all of it could be avoided if people had not been so conditioned to fear and hate anything with the word radiation or nuclear in it. Of course, we know who to thank for that conditioning as well.

Bush was the first person in power I ever saw who really started to push for clean energy and to throw us away from fossil fuels. In fact, I don't know of any other country even trying as hard as the US under Bush is--although information is changing all the time, so who knows. And I mean try, not simply talk about it. All the grants and subsidies to researchers working on clean fuel like hydrogen, and diesel and so forth, not to mention forcing the car companies to start upping gas mileage. There is a balance of course, things cannot be pushed too fast, or they will collapse, companies will go out of business, and technology will not have a chance to advance fast enough to meet demand leaving everyone hanging. The country has been in serious energy troubles ever seen so many nuclear reactors were shut down that we've had to expand coal power plants to meet the needs of the country, which has required going back on, though only a little, the clean coal initiatives. Everyone remember the horrible blackouts and rolling brownouts California faced not too long ago? Cali leaches loads of energy off of Washington State's hydroelectric system, but it isn't enough. What about the complete failure of the power grid a few years ago up in the North East? Heck, let's not even get into the incredible oil refinery problems and deficits we have right now. Why is gas so high when oil is falling in price? Because we have too few refineries to make gasoline for us. That is why Bush has had to push for initiatives to expand those areas of our economy--it is done out of necessity, all the while we're being pushed to finally give up coal and fossil fuels. Though, that isn't even to mention the initiatives Bush did put in to push all outdated coal plants to "clean coal". Gotta remember all those state of the union addresses. However, one man doesn't dictate everything. The government is vast and it's still up to people to actually execute ideas and suggestions.

It isn't easy being in "power". The needs of the people, their future, the needs of the environment, its future, the economy, defense, everything has to be balanced, and I'd be crazy to envy a job like the presidency. Personally, hydrogen fuel cells seem the only "good" solution out of all of those out there to head to at the moment. You're completely right about ethanol, and it's totally silly to switch to ethanol. I don't know why people want to, other than it comes from some other source than the ground... plant this time, but it is so incredibly ineffective. Diesel would be way better than gasoline, which is light years superior to ethanol, and I have no idea why it isn't pushed for as much as ethanol.

Ultimately though, I think we need to master atomic energy better, as chemistry has met its limits. Solar is totally a waste other than for back up systems unless we were to make more efficient solar cells, but we seem to be at the wall with that. Atomics and plasma are really the only higher energy sources we don't have a grasp on. But burning and photoelectric just aren't cutting it.

I don't care what your political views are, but misconstruing the facts is just...
This administration has made it easier for refineries and coal power plants to expand without meeting current emissions controls, let along proposed limitations.
It is an energy carrier. and it is horrible! There is not a hydrogen fairy that farts out the gas. It takes much more electricity to break water into hydrogen and oxygen. This energy would come from the coal plants we have! How is that a reduction in dirty sources? Then the hydrogen has to be shipped... Which takes tonnes of space and money. Plus- there is no material or technique known to man to hold enough hydrogen to run a car the distance of a gasoline counterpart. Fuel cells? ARE A BAIT AND SWITCH. They manufacturing returns are horrible, and they involve precious and rare materials such as platinum to work. and what do they do? Produce electricity! Batteries have a strong future, with li-poly batteries a very good source of storage. Also, capacitors are coming along. It was the federal government that came in and told California that it could not demand auto companies to sell electric vehicles, which killed the electric cars (watch "who killed the electric car"). as for gas mileage- cars in the 80's had better mileage. The fact that companies can offer a hybrid or ethanol capable vehicle and then have another that consumes more gas and pollutes more is not a step in the direction. and both bush and clinton are to blame. Diesel is a mucher better fuel than gasoline, but has more smog-forming emissions. where are the grants for bluetec technology? and why isn't algae-based diesel being looked into more? instead why divert cattle feed to ethanol, which has less energy than gasoline, and burns faster. We then ship corn from outside the country, diary prices rise, and we still burn tonnes of coal a day to produce ethanol. So how is this not wasteful: coal is mined, shipped to plant along with corn being shipped, then the coal is burned, and the ethanol produced, then the ethanol is shipped to refineries.... it is stupid to transfer one energy to another like that....
