You need to check out all the new curricula arising that is helping teachers understand the impacts of coal and the promise of new technologies.
As the director of KidWind we work on this problem everyday. http://www.kidwind.org
We have trained over 8000 teachers that impact close to 1000000 student a year and it is growing all the time. While we discuss the impacts of coal and damage it can cause we also spend a great deal of time discussing what is coming next.
We are not the only group that is doing this. Check out the Will Steger Foundation they have some great new curricula. http://www.willstegerfoundation.org/
Drop me a line happy to show your teachers what we do. We are in for the long haul...
