Yes, but economic break even is also an important concept. For example; PV economic break even will come far sooner for the off-grid person who is presently converting gasoline to kilowatt-hours than it would for someone contemplating a grid-tie syestem in an area with cheap electricity. > And fixing and maintaining it might kill the small net energy surplus. Again, maintenance is mostly an economic issue, it has less to do with net energy. That said, I agree that maintenance is an important and often overlooked factor. > And before we get to break even we might have new, much better technology. Yes, but demand, and the competition that demand generates, is a main driver for improving technology. If we just fold our arms and wait for technology to improve in the absence of demand, technology improvement is unlikely to ever happen. Vaughn

It is far safer to store high-level nuclear waste on-site and postpone moving it until it naturally decays to at least medium-level waste. >and we now know Yucca Mountain will not be opened. The problems with Yuca Mountain are far more political than scientific. The great irony is that the highly-trumpeted "nuclear waste problem" has been made insolvable my the anti-nukes. They have been very effective! Further, they refuse to realistically compare the dangers of nuclear power to the dangers of the alternatives. In the interim, the world is subjected to the ecological horror of more and more coal plants, and (statistically speaking) humans are dying form the emissions from those plants. Further, those plants also have an insolvable waste problem. Vaughn |
