Types of Power

Performance Objectives:

1. List the types of power generated from renewable resources.
2. List the types of power generated from non- renewable resources
3. Describe each of the methods and how commonly they are used.

Have you ever wondered:

“Is electricity just floating around in the

air?”

“How is it captured for our use?”

“I see the power lines that come into my

house, but where does the electricity

that’s on them come from?”

Sources

• Our power is generated for us compliments of our natural resources
• Renewable and Non-renewable

Non-renewable Resources

• Fossil fuels
  • Coal
  • Oil
  • Natural Gas
• Non-sustainable Woods
• Nuclear (uranium)

How are these resources converted

to usable means?

• Some type of mechanical generator!

Steam Power

• Fossil fuels
• Nuclear Fission
• Geothermal
• Solid Waste
• Wood

There are several sources of steam

power:

Coal

Accounts for about 51% of steam power generated electricity Decreasing in quality Increasing in pollutants

Natural Gas

Accounts for about 15% of electricity generated Quickly becoming the fuel of choice.

Nuclear Fission

Splitting uranium atoms produces a great deal of heat energy that is processed into electrical energy in nuclear plants.

Non-renewable Source

Nuclear Generator
