Nearly 30 years after Ronald Reagan tossed the solar panels Jimmy Carter had built into the White House roof, the Obama administration has completed installation of new panels on top of the executive residence.
It's a symbolic move by the White House as President Obama pushes new initiatives to stop climate change.
"The project, which helps demonstrate that historic buildings can incorporate solar energy and energy efficiency upgrades, is estimated to pay for itself in energy savings over the next eight years," he said.
The retrofit panels include updated building controls and speed fans, and will generate 6.3 kilowatts of solar power.
The panels are one piece in the larger plan by Obama to encourage energy efficiency and solar deployment across the country as a means of fighting climate change.
Obama will announce new commitments from government and corporate entities to up their solar usage and energy efficiency measures during his speech at a Wal-Mart store in Mountain View, Calif., on Friday.
