Advantages and Disadvantages

• Use the internet and any other material to find the advantages and disadvantages of various ways to make electricity. As you read, look for information such as the following:

• Is the resource renewable?• Can you count on it always working?• Does it cause pollution and what kind of pollution?• Does it take up lots of land?• Is it expensive to set up?• Is it expensive to run?• Can it be built anywhere or does it need to be built in a specific

place?

Natural Gas

• Advantages– Unlike burning coal, burning

natural gas does not release sulfur dioxide.

• Disadvantages– Burning natural gas releases

a large amount of carbon dioxide into the atmosphere.

Use the internet sites provided to find the advantages and disadvantages of using natural gas to generate electricity. Two have been done for you.

Think about pollution and

efficiency

Solar Cells

• Advantages • Disadvantages

Use the internet sites provided to find the advantages and disadvantages of using solar cells to generate electricity.

Are solar cells efficient?

How much do they cost?

Wind Turbines

• Advantages • Disadvantages

visit some of the internet pages to find out about wind turbines.

Think about the ways that the turbines affect

the environment

Hydroelectricity

• Advantages • Disadvantages

Think about what

happens to land

Think about pollution and

efficiency

More Advanced

• In the next slides you need to think about– Wasted energy – Extra energy transfers

Tidal Barrage

• Advantages • Disadvantages

Think about how the

barrage effects the

environment

Think about how much electricity we can produce and pollution

Wave Power

• Advantages • Disadvantages

Think about the reliability and

pollution

Think about the costs

Wood Burning

• Advantages • Disadvantages

Is wood a renewable resource?

Is there any pollution?

Geothermal Energy

• Advantages • Disadvantages

Is geothermal energy

reliable?

Where do the plants need to be

built?

Extra Tasks

• There are other types of energy resources that you might find out about. Look up and add slides about– nuclear power, – alcohol fuel or – hydrogen fuel cell or even – solar heating and add these to your show.
