Review Nonrenewable resources Renewable Resources Fossil Fuels The energy of fossil fuels is most commonly turned into electricity A fuel’s suitability (5 Things)  Availability, Cost, Energy content, Safety, By products In the US the main use of energy is for creating electricity Electricity/ Electric Generator

Energy Basics Where do we get electricity? Power Plants  Fossil Fuel Power Plants  Nuclear Power Plants Power Plants create electricity and that electricity is carried though a distribution grid When an electrical pole goes down, why does it affect more than one home?

Fossil Fuel Power Plants 1. Fossil Fuels are burned  They contain much energy that is released in the form of heat (this is a chemical reaction) 2. The heat turns water into steam 3. The steam is directed at the blades of a turbine, causing them to spin 4. The turbine is connected to a generator, the coils of the generator are moved through a magnetic field, creating electricity, which is sent out to the distribution grid

1. Nuclear Reactor runs fission reactions  They contain much energy that is released in the form of heat (this is a nuclear reaction) 2. The heat turns water into steam 3. The steam is directed at the blades of a turbine, causing them to spin 4. The turbine is connected to a generator, the coils of the generator are moved through a magnetic field, creating electricity, which is sent out to the distribution grid
