# Never took no science

 Some Elementary Science Power --- work per unit time --- is measured in watts (joules per second).  Work (or energy) can be represented as power multiplied by time.  In the international system of units (SI ), energy is in watt-seconds, or joules.   However, for measuring energy consumption, the utilities use the kilowatt-hour, which is the power in kilowatts multiplied by the time in hours.  (1 kWh = 3.6 million joules.) It would be nice if influential people knew this information from junior-high science.  They might not be tempted to spew --- worse yet, to teach --- such confused garbage as given below.  But, what can you expect from people who think leverage and science are verbs.  (Don't believe it?  Look up sciencing with your favorite web browser!) Ignorance at  Business Week "The drain from such devices in U.S. homes alone adds up to 5 billion watts per year " [emphasis added] Andy Reinhardt Business Week, October 5, 1998, p. 115 Ignorance in 6th grade textbook "How Much Power is Used in a Home Monthly?  Use is figured in kWh or kilowatt-hours.  What is a kilowatt? A 100 watt light bulb uses 100 watts per hour of use.It will use 1,000 watts if burned for 10 hours.A kilowatt is 1,000 watts." Chapter 3, Why is it Happening? of book for Grade 6, (Marco Press, 1997) http://www.opnated.org/6u3.htm Ignorance in "educational" website "A. If the wattage is given, divide the wattage by 1000 to get kWh. Then multiply by the cost of a kWh, approximately 7-1/2¢ (\$.075), to get cost of operation per hour." "     100 watts/hr. x 10 hrs. = 1000 watts" [Editor's note:  True, but meaningless arithmetic.  If these energy experts knew their subject, they might write: 100 watts x 10 hours = 1000 watt-hours.] http://ecep.usl.edu/ecep/home/b/b.htm (Energy Conservation Enhancement Project, Louisiana)
