Interesting Facts about Electricity
A bolt of lightning can measure up to three million (3,000,000) volts – and it lasts less than one second!
Electricity always tries to find the easiest path to the ground.
Electricity can be made from wind, water, the sun and even animal manure.
Burning coal is the most common way electricity is made in the United States.
The first power plant – owned by Thomas Edison – opened in New York City in 1882.
Thomas Edison invented more than 2,000 new products, including almost everything needed for us to use electricity in our homes: switches, fuses, sockets and meters.

One power plant can produce enough electricity for 180,000 homes.
The bicycle is the most efficient form of transportation known. It uses five times less energy than walking.
B.C.’s forest industry obtains 25% of its electricity from biomass — in this case, the waste material from their own industry.
