- Lightning is a form of electricity. Electrical charges develop inside a storm cloud with positively charged atoms moving to the top of the cloud and negatively charged atoms moving to the bottom. When the negatively charged atoms get too crowded, they move to a new location, sometimes the ground.
- In 1700 Benjamin Franklin figures out that static electricity and lightening are the same. This paved the way for future development of electricity.
- 7% of power generated at large central stations is lost during transmission to the user over high-voltage lines.
- 10% of total US generating capacity is fuelled by natural gas, about the same as hydropower. More than half of US capacity is coal-fired, with nuclear accounting for 20 percent.
- 24 cents per kWh: Price charged for electricity produced at Thomas Edison's first plant, built in 1882. Current average US price is about 6.3 cents/kwh.
