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's a lot more that you need to factor in for nuclear/coal plants. They need mines, then the raw materials must be transported requiring streets/oil/... Preprocession, storage, retransportation...
If you sum that all up there's a lot more space wasted than appears.

For coal plants, sure. Not nuclear. A CANDU fuel rods bundle is small enough you can easily hold it in one hand...and it'll generate over 1M kW-h of electricity. One single truckload of those can supply an entire nation with power for a year.

Furthermore, some modern nuclear reactors can use raw uranium, not enriched, meaning there's need for a preprocessing plant.

The Portugal solar plant requires two truckloads a week. Not of fuel but rather cleaning solution, brought in to clean those huge arrays.

off-site land is an issue with fossil fuels more so than nuclear- just as the DT staff has pointed out about three times so far.
But you cry foul about it with current technologies, but not offside pollution for solar arrays! The solvents needed to create the silicon crystals in their formations are highly toxic and carcinogenic. The doping agents used for the cells are also dangerous. Mining is done for arsenic which is also a doping agent, and it is released during processing, and is shipped from mine to manufacturing site too. The cells also lose efficiency over time. They produce less and less power each year, need replacements and repairs, and do you really think they will be disposed of properly?
In conclusion:
there are NO FAIRIES that poop out solar panels, hydrogen, ethanol, or uranium fuel rods. People need to form whole opinions when hearing about "green" alternatives, because industries make a habit of only including charts, graphs, and info that reveals a portion of information that makes things look attractive.
