Agree on a full investigation without bias. I think all power sources were affected in some degree, but forgive me for continuing to beat this drum...the key was winterization. Wind power can be and is winterized and utilized in cold climate areas of the world. Wind is a major energy source in " tropical" Denmark..and Sweden deploys wind for power supply in large amounts. So it boils down to use of budgetary capital to properly construct and maintain these alternative supply sources. That's a political issue the world is now grappling with. While China continues to burn "dirty" Mongolian coal, it also is the world's largest wind energy generator. While I'm at it.....We need, all of us, to get the heck away from this divisive Red/Blue Left/Right crap that's ruining this Country and get back to trying to work together on the issues that will keep our Republic alive. Not wanting to jump in the deep end here, just a thought to try a little harder to see someone else's point of view, realize we are a true melting pot of ideas and ideologies, and reach solutions built on ingenuity,compromise and creativity. Sorry to rant, just wanting to move ahead to get some things done. ( energy supply in this case)
