I assumed you omitted it because we've already tapped all the best/most immediately available sites for large hydro plants, but I have no reason to actually assume that's the case. So, uh, why?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9560953.post-1145296729585384662006-04-17T13:58:00.000-04:002006-04-17T13:58:00.000-04:00Which is more environmentally sound: one large hyd...Which is more environmentally sound: one large hydroelectric plant, screwing up one large river, or two dozen small hydroelectric plants, screwing up two dozen small rivers?<BR/><BR/>A lot of people (not necessarily here) treat hydro as benign, and it ain't.AJSomersethttps://www.blogger.com/profile/17373030698483060863noreply@blogger.comtag:blogger.com,1999:blog-9560953.post-1145294466783847082006-04-17T13:21:00.000-04:002006-04-17T13:21:00.000-04:00I agree with your post.

That's worse than wind power.<BR/><BR/>Uranium is limited, and will get more costly as many countries start using even more nuclear power generation.<BR/><BR/>Transmitting power a long way is expensive and results in greater inefficiency as there is power loss over the lines.<BR/><BR/>Nuclear generators take a long time to restart (days, not hours) - at least the ones in Ontario do. <BR/><BR/>Alternative power sources are: tidal, hydro, wind, solar, biomass AND conservation.<BR/><BR/>Biomass plants are fine (to a point) if they respect the carbon cycle.Mark Richard Francishttps://www.blogger.com/profile/16331995640397477486noreply@blogger.com
