Nanotechnology could shrink the cost of solar power generation

Shrinking solar, expanding profit
Konarka, Nanosolar and Nanosys say that nanotechnology could make the price of electricity less expensive per watt.
Current cost of solar energy, per watt: $4-$5
Average cost of energy from traditional fossil fuel sources, per watt: $1
Estimated cost of energy from nanotech solar panels, per watt: $2
Total energy-generating capacity of the United States: 950,000 megawatts
Potential total rooftop solar energy capacity in the United States: 710, 000 megawatts
