stored in a warehouse in Franconia, Virginia. An official from Unity College, a private college in New Gloucester, Maine asked that they be released to them, and they were moved to the college in an old school bus and installed in 1992. The panels were used to reheat water for the college's dining hall. The college received a letter from Carter expressing his happiness at their installation. In October 2004 the college planned to auction the solar panels as they had become outdated. Three of the panels are part of museum collections. One of the panels was donated by Unity College to the National Museum of American History in 2009. Another is on display at the Jimmy Carter Presidential Center. A third panel has been part of the Solar Science and Technology Museum in Dezhou, China since 2013. 21st century In 2003, the Bush administration reinstalled solar thermal heaters. These units are used to heat water for landscape maintenance personnel and for the presidential pool and spa. One hundred sixty-seven solar photovoltaic grid-tied panels were installed at the same time on the roof of the maintenance facility. The changes were not publicized, as a White House spokeswoman said the changes were an internal matter. The story was picked up by industry trade journals. In 2010, the United States Secretary of Energy in the Obama administration, Steven Chu, announced that solar panels would be reinstalled on the roof saying that "As we move towards a clean energy economy, the White House will lead by example". The panels were installed in 2013, making it the first time solar power would be used for the president's living quarters. References 1979 in American politics 1979 in Washington, D.C.
