Betti so nice to see you back!

As far as what I have read the Chinese have dome sever damage to the eco system with their damming and some say it was intentional. I didn't mean that river's should be dammed for profit. I was talking more on a per home basis with smaller pumps and generators.

As far as inverters go, I really think it is a severe waste to use 110/120, Using 12V systems may require a bit more amperage but not nearly the amperage one uses with higher voltage. It is the constuction of the devices where I think we are failing. If a laptop can run non-stop (as long as plugged in) using 12 volts 60 watts at 5amps, then why am I typing on a desktop & monitor that uses 110 volts 800 watts and running at many more amps?

I know why. The energy companies are securing their future. The same reason to convert a home to 12V in the USA is more than 6X the price of a 110V system.
