15 Interesting Facts About Electricity
- The first use of water to generate electricity was in 1882 on the Fox river, in the USA, which produced enough power to light two paper mills and a house.
- 10 percent of total US generating capacity is fueled by natural gas, about the same as hydropower. More than half of US capacity is coal-fired, with nuclear accounting for 20 percent.
- 212 billion in electrical bills are paid by US customers each year.
- An electric oven uses one kilowatt-hour of electricity in about 20 minutes, but one kilo
watt-hour will power a TV for 3 hours, run a 100-watt bulb for 12 hours, and keep an electric clock ticking for 3 months.
- An Electric eel can produce an electric shock of up to 860 volts at one ampere.
- Currents of approximately 0.2 A are potentially fatal, because they can make the heart fibrillate, or beat in an uncontrolled manner.
- Early in their history, Christmas lights were so expensive that they were more commonly rented than sold.
- An electrically lighted tree was a status symbol in the early 1900s.
- A 100-watt modern light bulb emits about 1600 lumens, while a single flame oil lamp form the 1800s emitted about 2400 lumens.
- A generator is a device that converts mechanical energy into electrical energy. The process is based on the relationship between magnetism and electricity.
- The cost of electricity is going up (both in dollars and in environmental and health impacts) and it doesn’t show any signs of doing otherwise.
- About half of the energy in the American grid is coal generated.
- Electric energy is an intermediate form of energy. It is produced in thermal power stations (where fuel oil, gas, coal, biomass, etc. are burnt), in hydroelectric power stations and nuclear power stations. Smaller quantities are produced by wind, photovoltaic solar panels, sea tides, etc.
- When electricity was first introduced into the domestic environment it was primarily for lighting.
- In the late-1800s, Nikola Tesla pioneered the generation, transmission, and use of alternating current (AC) electricity, which can be transmitted over much greater distances than direct current.
