Take a look at this list of countries utilizing hydro-electricity generation:https://www.cia.gov/library/publicat...elds/2045.html
What I find surprising from this list is:
1) The countries that squawk the loudest about the need to employ greener technologies are also amongst those that least utilize hydro generation.
2) Many so called "third world countries" are amongst some of highest in terms of the percentage of their electricity requirements generated by hydro.
3) Many countries utilize hydro electric for at or near 100% of their electricity generating requirements.
In addition to the natural cycles of mother nature I can concede that mankind's activities are also contributing to global warming but I question whether carbon is the real culprit.
Surely the possibility that merely HEAT from all the combustion processes occurring on the planet is contributing to atmospheric warming and I think that developing the emerging co-generative technologies that recycle heat into useful energy is worth pursuing.
