MONTPELIER, Vt. (AP) -- Vermont Gov. Peter Shumlin is defending his administration's goal of having Vermont use 90 percent renewable energy by 2050.
The state energy plan has come under increasing questioning recently from some quarters. There's concern, for instance, that it would require a big expansion of mountain-top wind power projects like those generating power and controversy in Sheffield and Lowell.
Shumlin says that any big social change such as the one that's needed to respond to climate change makes some people upset.
Shumlin made the remarks in Moretown, where he went Monday to announce a $700,000 grant to replace a municipal office building severely damaged during Tropical Storm Irene of 2011.
Shumlin says Irene is "just a little warning for what lies ahead" with climate change.
