#30#29, me referia tambien a considerar la contaminacion que producen por metales "raros" (selenio, indio, etc...) las placas solares una vez terminan su vida util. ¿Que se hace con ellos?
Una comparativa curiosa sobre el coste de fabricacion:
It takes one Gallon of Oil to produce 40 gallons of Oil
A 40 to 1 increase in net available energy
Now lets do a few more:
It takes ten pounds of Coal (strip mined) to produce 2000 lbs of Coal
A 200 to 1 increase in net available energy
_______________________________________________
One ounce of 6% enriched Uranium produces 600 ounces of 6% enriched Uranium (6% +/- is standard for most refueling of nuclear power plants vs. a nuclear bomb uses 99.9 % enriched uranium)
A 600 to 1 increase in net available energy
________________________________________________
1 Therm of Natural Gas is needed to produce 100 Therm’s of Natural Gas ,
A 100 to 1 increase in net available energy
___________________________________________________________________________
Five Solar cell’s life span/usable energy will produce 1 solar cell
A 500 percent decrease in available energy
______________________________________________
One Windmill life span including operation will produce 1.5 windmills
A 1.5 to 1 increase, not a good resource/investment

One pound of Corn will produce 1.5 pounds of Corn
A 1.5 to 1 increase, not a good resource/investment
