Solar Roof Panels on the White House
In 2010 the Obama administration announced that it would re-installed solar panels on the roof of 1600 Pennsylvania Avenue! The completion date for the project was originally Spring 2011 and finally got completed in 2014.  Hip hip hurray!

On June 20, 1979, President Carter installed 32 solar thermal panels to generate hot water, but the panels were taken down (and not reinstalled intentionally) while the roof was being resurfaced in 1986 while Reagan was president.
