The Energy Story - Chapter 3: Resistance and Static Electricity
Around 600 BCE (Before the Common Era) Greeks noticed a strange effect: When rubbing "elektron" against a piece of fur, the amber would start attracting particles of dust, feathers and straw. Glass, however, when rubbed with silk, acquired what he termed "vitreous electricity." He thought that electricity repeled the same kind and attracts the opposite kind of electricity

The American Wind Energy Association, which also supports the EPA rule, recently published a study that found that consumer rates declined over the past five years in the 11 states that use the most wind, while rates increased collectively in all the other states during that same period. If the EPA rule reduces the use of coal, it also would reduce emissions of conventional pollutants that contribute to asthma, other lung diseases and heart attacks, according to a joint study by the Harvard School of Public Health and Syracuse University Center for Health and the Global Environment

The Energy Story - Chapter 7: Electricity Transmission System
From these substations (like in the photo to the right), electricity in different power levels is used to run factories, streetcars and mass transit, light street lights and stop lights, and is sent to your neighborhood. The voltage is eventually reduced to 220 volts for larger appliances, like stoves and clothes dryers, and 110 volts for lights, TVs and other smaller appliances

Daylight Saving Time - Saving Time, Saving Energy
Initial analysis by staff of the California Energy Commission says a similar study may not yield the same results for California because: The use of residential air conditioning is relatively low in Indiana, and the saturations are low. Because people get home from work and school and complete more errands and chores in daylight, Daylight Saving Time also seems to reduce people's exposure to various crimes, which are more common in darkness than in light
