Congratulations, Wilde Lake Middle School, for committing to zero net energy consumption from heavy polluters such as coal, fracking and incineration ("Wilde Lake Middle prepares for new building," Aug. 24). You join The University System of Maryland Foundation, which recently cleaned up its endowment by steering all future energy investments away from carbon industries. The Ravens training facility in Owings Mills is also covered with solar panels. Hopefully more equally large institutions — schools, corporations, wings of government, etc. — will promptly jump in line for the future.
