If the earth receives 88,000TW of energu from solar sources and is 500 trillion dquare meters (500 * 10^12 for those that like numbers this way) in size.
How many watts/square meter does this represent ?
If one watt of energu flow is equal to a joule of energy oer second, how many Joules fall on a square meter of the earth's surface every year?
then If 12 percent of thoes solar energy resources could be harnessed , how long would it take for an average 50 square meter solar array to fill up a car with the energu equivalent of 15 gallon thank of fasoline?
