Renewable and Nonrenewable Energy Resources Presented by David Dean
Learning Objectives All: To describe at least 3 renewable and at least 3 nonrenewable energy resources Most: To explain how different renewable and nonrenewable energy resources work. Some: To evaluate the advantages and disadvantages of different energy resources.
We all use electrical items every day.
Some use batteries the mains Some plug into
● Mains electricity is used to power larger items that need more energy. ● It is usually produced by moving a magnet really fast near some wires in a machine called a generator. ● Because we use it constantly we need to keep this magnet moving as fast as possible all the time. ● This is what happens in a power plant.
Power plants come in many different types. ● Some methods of keeping the generator working are nonrenewable. This means that the energy source will run out one day. ● Some methods of keeping the generator working are renewable. This means that the energy source will run not run out, or at least will be available for a very long time.

No energy resource is perfect. ● Each one has advantages: It may be reliable, renewable, produce a lot of energy, we may already have lots of that type of power plant built. ● Each one has disadvantages. It may be nonrenewable, produce harmful gasses, cause global warming, be potentially dangerous or only be available in some places.
