Norwegian hydroelectric plants usually don't destroy a ecosystem, just some nice looking waterfall. They have so long and steep falls that ecosystem would be naturally separated by it anyway.
- avar 14y agoThat's not the only damage hydroelectric does. The damns normalize naturally occurring floods with a view to maximizing electricity production, and material that would have been carried to sea gets trapped behind the dam.
- rprasad 14y agoIn a traditional hydroelectric generator, yes. Norway has the advantage of numerous, steep cliffs and waterfalls. It is my understanding that the Norwegian HEG's are placed in the middle of the waterfalls, so that no dam is necessary...
- noselasd 14y agoThat's hardly ever the case, and would be quite inefficient unless the waterfall provides the same amount of water all year. Most hydroelectric power in Norway are generated with the help of a reservoir, usually a natural lake that's been regulated with the help of a relatively small dam, but there are some wholly artificial ones as well, the biggest one being 84 square km. That said, yes - the environmental impact is small. It also helps that the Norwegian population is very small.
