The interesting thing is that end customers are more interested in costper kwh than cost per watt. The first speaks to what it does for them and so remains much more important.

The current cost per kwh for a system in Toronto is $0.32 over 35 years. The grid feed costs $0.11 per kwh delivered, and the fact is that the greed feed is subsidized all over the place and those costs are not charged to end users (ask your utility why commercial ops pay less than residential consumers). All in or full cost models actually show electricity costs $1.50/kwh from macro-generation to end user.(germany) In the greater expanse of North America this is likely higher. Can anyone tell me the life expectancy of high voltage transmission lines? They cost about $3mn/km to build. If you assume a 40 year life, just moving electricity from a hydro station to a city that's 150 km's away costs $4.73 per kwh without any line loss costs added. O.k fine, you can assume that the wires last 100 years...that's still $1.89/kwh without line loss and without operation and maintenance.

If you want to chnage the world simply demand the whole truth...common sense will do the rest for you.
