Poll

How do you think Clovis NM gets electricity that people can use in their homes?

• Wind Energy

• Coal energy

• Nuclear Energy

• Hydroelectric dams

How is electricity made?

There are many ways that depend on our geographical locations.

Multiple Choice

• True

• False

Multiple Select

Which of these is a source of energy? Choose all that apply.

• Coal

• Wind

• Biological wastes

• Water

• Nuclear energy

Multiple Select

What does it mean to say that "electricity is less centralized"?

• People commonly use a locations natural resources for energy.

• Electricity is closer to the consumers.

• More options exist for electricity.

• Electricity is in one main location.

Multiple Choice

Which of these is true?

• Voltage is lowered in steps for use in homes and businesses.

• Homes used very high voltage electricity.

• Voltage must be NOT lowered for use in common electronics.

Generating energy.

How does the power get made?

• Copper wire is wound around a casing and spun around on a rotor.

• Strong magnets surround the coils as the coils spin.

• An electric field builds and electrons start to flow in a current.

• The electrical current can be sent through conductive wires to other locations.

Multiple Choice

Generators are the opposite of a .....

• motor

• transformer

• electron

• power plant.

Multiple Choice

A generator is basically....

• coils of wire turning inside a magnetic field.

• magnets circling a bigger magnet.

• coils of wires that have embedded magnets inside.

Poll

Which kind of current is used in homes.

• AC - Alternating Current

• DC - Direct Current

Multiple Select

How could you raise the amount of current made in your generator?

• Add more coils of wire

• Add a stronger magnetic field

• Make the wire loops bigger.

• Speed up the rotations of the wire.

• Slow down the rotations.

Multiple Choice

Why do we transport power at high voltages?

• So birds get shocked.

• So it goes faster.

• So less of the energy is wasted as heat.

Poll

Do household appliances use high voltage electricity?

(up to 240,000 volts)

• Yes

• No

• NO WAY - VERY UNSAFE

• Yes. Great Idea.

• Biofuels are using a living organism or its waste to create energy.

• Los Alamos is a national lab that is famous for the Manhattan Project.

• I (Ms.Minteer) worked on algal biofuels for my master's degree work at ENMU.

• This is popular in NM because we have an abundance of sunshine and nice days. Algae like lots of sun to grow.
