Old energy Sources being Destroyed.

I was watching CNN yesterday and came across some interesting news. In the past we have used dams for a source of energy. It was considered the easier way to generate energy. Now, we have other methods of generating this energy such as solar panels, wind mills etc. The average price to maintain these dams per year is roughly 302 million dollars. The dams also mess with natural habitat. I would imagine over the next ten years we will see these dams be blasted with sticks of dynamite one by one.
