Clean Renewable Energy

I just got home after a couple of days in Lewiston.  The drive is about five and a half hours from the Idaho/Washington border, across farmland, the Columbia river, Snoqualmie Pass and into Puget Sound.  The last couple times I made this trip, I noticed that more and more of the wind turbines were popping up everywhere on the nearby hills along I-90, just west of the Columbia river.  I've always been fascinated by them.  Initially, it was mostly their looks - white, sleek columns towering into the sky, elegant and willowy.  I've always liked their purpose and what they stood for - mining clean, renewable energy resulting in a more evolved and sustainable future for us and our planet.  That gives me hope.
