Transcript of Making Electricity

Generating Electricity Renewable Resources Non-Renewable Resources Fossil Fuels Advantages Disadvantages Coal, oil, and natural gas
cheap
easy to get. Fossil fuels
Pollute the air
Contribute to global warming Nuclear Energy Advantages Nuclear energy is clean
and does not pollute the
air. It is also not
expensive. Disavantages Nuclear waste must
be disposed of. It
remains radioactive
for decades. Hydroelectric Advantages - It does not pollute
the air.
- It never
runs out. Disadvantages - Dams can only be
built in cerain areas.
- It disrupts the
environment of certain
animals. Wind Energy Advantages - No air pollution.
- Cheap supply of
energy. Disadvantages - Wind turbines must
be built where wind
blows constantly.
- Spinning blades can
kill migrating birds. Solar Energy Advantages Disadvantages - The sun is not
always shining.
- Solar panels are
very expensive. - It is very clean.
- It never runs out.
- Requires no turbine
or generator. How to Produce Electricity Electricity is produced by a
device called a generator.

To produce electricity, the coils of
wire in the generator must be
rotated rapidly within a magnetic
field.

A turbine is often used to turn
the generator. Steam, wind, or water can be
used to turn the turbine. Hoover Dam Steam Turbine Wind Farm
