Of course, dams are not *primarily* for the purpose of generating power, but
rather for water control. For this analysis we must somehow take into
account the value of property not destroyed by flooding because of the dams.

If we take that into account, we get to add all the energy saved from those
million people not living there anymore.

Furthermore, we have just begun to find the most efficient biofuels. That
is an area that will improve dramatically.

This is an understatement in a way. Wind power takes a lot of area, but it
doesn't actually use up the land. Biofuel crops can be grown among wind
turbines (an example is near the Altamont Pass in Taxifornia). PVs can also
be collocated with the turbines.

We know of the negatives, but there are many positives. Countries all have
their own wind and their own sunlight, even if some have more than others.
No need to fight over resources.

It's all in the way it is described. Rather let us transform massive
landscaping with pleasant industrial transformation.

If one buys into this notion, one keeps running up against the same
attitude: two legs bad, four legs good. But there are a lot of us two
legged things who disagree, and a whole lot more coming in the near future.
For instance, as China becomes wealthier, they will want more children than
the one-child family that has been given to them. Watch for a wave of two
child families to start showing up in China.
