What about nuclear power plants?
Similar situation. They cost between $4-8 billion to construct. That's a LONG time till profitability, and by about the time that time comes, they'll likely be in the process of being phased out by alternative energy sources.
Besides, why do we need them anyway? We still have plenty of cheap electricity.
Umm last time I check my electricity rate has been steadily increasing over the past three years. Not at the same rate as gasoline but still a significant amount. I'm hopeful that it will level off a bit though as wind and solar farms continue sprouting up.
Don't hold your breath.
While I like solar power, its only viable in certain areas.
As to wind farms, very few places have sufficent reliable wind to support such a technology.
