Solar panels are a popular choice for homeowners who want to take advantage of alternate energy sources. These systems are a way for consumers to save money and conserve energy at the same time. Even the nation’s most famous address is doing its part. In 2010, president Barack Obama decided to install solar panels on the white house as part of his administration’s focus on environmental issues, But Obama wasn’t the first president to use alternate sources of energy at 1600 Pennsylvania Avenue. The first solar panels were placed on the presidential mansion more than 30 years ago.
President Jimmy Carter installed 32 solar panels on the white house during the Arab oil embargo in 1979, which had caused a national energy crisis. Carter was ahead of the times. He set this example for the American people as part of a campaign to conserve energy. Carter said that the solar panels were "a small part of one of the greatest and most exciting adventures ever undertaken by the American people. "The use of solar panels had a goal: to reduce the United States’ dependence on foreign oil by garnering the power of the sun.
President Ronald Reagan took office in 1981, and he had very different views about energy consumption. He wanted on the panels taken down. In 1986, they were removed during construction on the white house roof.
Obama reinstalled the white house solar panels as well as a solar water heater in the spring of 2011. Administration officials said they expected the photovoltaic system would convert sunlight to 19,700 kilowatt hours of electricity a year. According to the associated press, that would save a typical household in Washington, D. C., an average of $2,300 on its annual electricity bill. The white house is just one of many American homes making an effort to reduce its reliance on nonrenewable resources.
