Answer: A) 1366 watts

Known as the solar constant, there are 1366 watts of solar radiation hitting each square meter of the Earth on average. To put that in perspective, if 100% of that energy were converted into electricity, one square meter's worth of sunlight would be enough to power roughly 80 17-watt compact fluorescent light bulbs.
