As promised by Energy Secretary Chu and White House Council on Environmental Quality Sutley in 2010, the Obama administration is joining the legacy—alongside Presidents James Carter and George W. Bush—of using solar energy to power the White House.
The solar panels being installed on the White House are an important symbol of federal commitment to renewable energy. Even more important, however, is the administration’s greater commitment, which Juliet Eilperin reports as a pledge to generate 20% of the energy consumed by the federal government—including the military—from renewable resources by 2020.
20% of federal energy use isn’t a huge number in global, or even national, terms. To put it in perspective, we consume about 4.4 million Gigawatt-hours each year in the US, while 20% of federal energy consumption only amounts to about 3 Gigawatt-hours. But every bit counts! Worthwhile progress is often piecemeal—and to cast it in more relatable terms: generating 3 Gigawatt-hours from another source would require, for example, over 3,200 pounds of coal. By getting that energy from the Sun, we spare the atmosphere more than 63,000 pounds of carbon dioxide.
The panels at 1600 Pennsylvania Ave. only represent a small fraction of this overarching goal, but greening the White House is, in my opinion, wise both for both politics and aesthetics.
To the sun god!
