A solar panel array now adorns the roof of the White House and will produce an elephantine amount of solar power when the sun is actually shining: about 44 kilowatt hours of electricity a day.
If 44 kilowatts hours sounds like a lot of energy, it isn’t. The average home consumes about 30 kilowatt hours (kWh) of power each day. The average annual electricity consumption for a U.S. residential utility customer was 10,837 kWh according to the EIA for 2012 or 30 kWh per day average.
Slightly less than the 44 kilowatt hours per day that will be produced by the new solar panels adorning the White House. According to data from TradeWind Energy, one 100-watt light bulb running for 20 hours will use two kilowatt-hours of electricity (100 watts x 20 hours = 2,000 watt-hours = 2 kWh).
In other words, the White House installed enough solar panels to power twenty-two 100-watt light bulbs for 20 hours each day. And if you’ve ever been inside the White House, or seen it from a distance, you’ll notice it’s lit up like a klieg light. …
If the average American knew how much this cost the taxpayer, they’d realize this is not cost-effective at all. Which is specifically why the White House refuses to release the numbers.
Obama seeks to use his personal example to spur American families and businesses to do more to reduce reliance on foreign energy and cut emissions blamed for global warming.
The new solar array, not seen since the Jimmy Carter Administration, and later, George W. Bush (who used it to power a maintenance building and heat some pool water), will be able to power 22 100-watt bulbs for 20 hours (unless it rains, snows, or is a cloudy day), far less than his two predecessors.
