They're at 55% renewable generation now and expect to get to 90% when the current round of construction ends in a couple years. After that they're going to look at the infrastructure changes needed to get to 100% renewable. All while keeping rates steady and making a tidy profit.
Claims that we will do nothing to stop global warming because of the cost are simply out-dated. We will stop global warming because continuing with current fossil fuel based power generation would cost MORE than switching to renewable power.
The other day I was listening to a report about the cultural importance of the coal industry in the Appalachian coal country. The interviewees expressed a universal opinion that coal mining was so culturally important on a local level that their children would just never, ever stop mining coal. Living in coastal New England, I couldn't help but think of all the whaling museums we have here.
Whaling was and still is culturally important to us, but we don't do it because whale oil isn't a viable lighting source anymore. I think in 50 to 100 years we'll have coal mining museums throughout the Appalachians, but coal mining won't be how anyone earns a living at that point. Geological studies will get the same respect that Oceanological studies do here in coastal New England right now.
My point has something to do with the economic replacement of combustibles with renewable energy sources, but I still heat my house with a wood stove, so I guess I'm a hypocrite. Maybe I'm just saying we'll have to wait 50 to 100 years before people stop arguing about global warming for the sake of politics, I don't know.
Anyone ever read the book Rocket Boys, or see the movie version, called October Sky?
