Finally, Harpers put 25 years of the index online, and it’s searchable.
The results for “sex” are… illuminating. Of course, I typed in “bicycle” too:
- Percentage increase, since 1975, in the number of Americans who commute to work on bicycles: 325
- Number of bicycles for every car in China: 200
- Energy, in megawatt hours, saved over thirty-five years by a bicycle rider who does not drive a car: 109
- Portion of these savings that will be used up over the extra years the biker will live: 9/10
Mega means million and a watt is a unit of power.
A megawatt hour is the amount of power used if 1,000,000 watts are used for 1 hour, or 1 watt is used for 1,000,000 hours. If 100 light bulbs each using 1,000 watts of power are turned on for 10 hours, they will use 100 x 1,000 x 10 watt hours = 1,000,000 watt hours = 1 megawatt hour.
Most electric companies charge for the number of kilowatt hours used. A megawatt hour is 1,000 kilowatt hours.
