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: 6.3 kilowatts.
If 6.3 kilowatts sounds like a lot of energy, it isn’t. The average home consumes 27 kilowatts of power each day. Far more than the 6.3 kilowatts that will be produced by the new solar panels adorning the White House. According to TradeWind Energy, “one 50-watt light bulb running for 20 hours will use one kilowatt-hour of electricity (50 watts x 20 hours = 1,000 watt-hours = 1 kWh).”
In other words, the White House installed enough solar panels to power six 50-watt bulbs for 20 hours each day.
