World's Largest Solar Power Plant To Supply Enough Energy For 1.1 Million People (computerworld.com)

Lucas123 writes: The world's largest solar power plant is now live and will eventually provide 1.1 million people in Morocco with power and cut carbon emissions by 760,000 tons a year. Phase 1 of the Noor concentrated solar power (CSP) plant went live last week, providing 140 megawatts (MW) of power to Morocco. Phases 2 and 3 will be completed by 2018 when the plant is expected to generate more than 500MW of power. The Noor plant, located in south-central Morocco, will cover 6,178 acres and produce so much energy, that Morocco may eventually start exporting the clean energy to the European market.

Ouarzazate gets a little over 3,400 hours of sunshine per year while Gibraltar gets about 400 hours less. Also, as you go poleward, the sunlight is spread over a wider area, meaning that it's less intense at any given location. Gibraltar is at the southern tip of Spain, so this gets more pronounced if you go farther north. If you go north to Madrid, you can subtract roughly another 200-250 hours of sunlight each year while being nearly ten degrees latitude farther north. There's also a whole lot less seasonal variation in the amount of sunlight at Ouarzazate than at either location in Spain, making it more suitable for a constant supply of electricity that doesn't require being supplemented by something else.

    The solar plant is actually at a great location, so it probably makes sense for Spain to by their electricity from Morocco than to build their own solar plant. In cold enough climates, the electricity demand might be high enough during winter that, if it can't be met with solar, it would be necessary to build another type of plant to supplement it or to buy the electricity from another country.

That is: there is not a continuous connection between an outside-facing metal surface and an inside-facing metal surface. This is because they use one nail every 6 inches, or 4,800 nails to fasten rigid insulation to wooden sheathing across a 30 foot x 40 foot wall. That provides a six square foot radiator plugged directly into your house by a distributed 0.7 square foot metal rod. It's not much, but it is a six inch metal bridge into your house; you have to blow enough warm air across that to keep that six inches of your wall room-temperature constantly, which means you lose quite a bit of heat (up to 10% with steel, much less with stainless steel) out that hole (for every 0.1kW, it's 72kWh or $10-$15/month of loss; it can near a third or more of a kW in extremely low outdoor temperatures).

    Do you want to cut down 5 million acres of forest or 5 million acres of forest? For that matter, do you want to cut down 5 million acres of forest in one spot, or do this in little pockets and cut away another 3 million acres of forest so they don't cast shade on your solar panels?
