Hydro in large KW production is the least damaging of all, a lot less than steam generating plants that pump large amounts of pollutants into the atmos. unless those steam plants are nuke plants and no one seems to like them. and we can't throw the baby out with the bath.
To my way of thinking, SEX is the worst form of damage to the Eco systems, with the growing populations world wide there is a continuing need for more power to fuel industry, ease of living and more comfortable living, If the head counts could be reduced to 1900 numbers then the drain on the resources would be cut and therefore less damage to the environment. But that ain't gonna happen.
So we have to look at what we can do to make the least damage and still live in the style that we have became accustomed.

If every home would set up some system to make just 1/2 of their own power it would help, but people just ain't gonna do that. I did do it for a few years because my home was 10 miles from the end of the grid and I had to do it, which did cost some money and I still lived with a somewhat easy and modern lifestyle.
We had a propane reefer, a DEQ approved wood burning heater stove, propane cook stove, propane burning gen set for batt charging when we had no sun but used very little as we had a large battery bank and could go long periods with out charging. But we were so far north that we only had 2 hours of sun during a day when there was no cloud cover for part of the year.
I had a friend that had a small creek on his property quite a ways above his house and he went down low into the creek bed and took water from below the freeze line so he had water in his pipe the year round, ran it downhill to his house, ran it thru a small pelton wheel and turned a high output alternator and got about 10 amps 15 volt power to his bank and had plenty of 120V thru his inverter, He also had 12 phone jars and figured to 4000 AH.

Thailand would be a good place for solar but you have to invest a lot of money in solar panels and batterys before it would be feasible and then you would still have to figure a way to run reefers as they are a necessity anymore and are real power hogs, ceiling fans could be run at 12v, but air cons would be out.
Maybe if your system was large enough to power reefers in the daytime, you could make holdover systems and charge them during the day and get by that way.But a good holdover system would require at least R 50 factor insulation in the cabinets and fairly large plates. But I do understand how to set them up and might give it a try someday.

Dams are somewhat invasive but are about the best thing now but are hard on some fish populations but we have to figure out what we can live with and what we can live without, and then go from there, dams are not forever as they will eventually fill with silt, takes many years tho, but it gives us more time to finally decide that nukes ain't so bad.
