Document Summary
Spinning is key to generating electricity whether it be by fossil fuels, magnetism, water or wind. The usa accounts for 20% of global electrical production. Measured in net production because power plants require pwer to run and the usa uses some for production as well. Does include electrical losses (some of energy is lost because of heat that escapes). Kwh (kilowatts per hour) is a unit of energy. Transportation doesn"t use much electricity, residential, commercial and industrial do. Use of renewable has risen in recent years. Use of coal is steadily declining, been displaced by natural gas. 67. 2% of electrical generation comes from fossil fuels. Nuclear sources stay at a solid 20% of electrical generation. Use of hydropower will decline if energy consumption continues to increase because there are so many rivers you can dam up/use. Electricity is some form of energy in transported charge. Electrical charge: fundamental particle, electron, that carries a negative charge.
