Solar and Wind Energy Ch 18.3

Solar and Wind Energy

Unit 5 Chapter 18.3

Take notes as we go!

Open Ended

Predict: how can we harness more energy from the sun in order to maximize our renewable energy usage?

Multiple Choice

Is solar power renewable?

• Yes

• No

• Sometimes

• Only in some places

Multiple Choice

Solar enegy can be converted into

• heat, electricity and power

• heat

• electricity and heat

• electricity

Multiple Select

Check passive or active.

This heating system is simple: reduce heat loss and increase heat gain from the sun. Can be used in homes and businesses when nothing is necessary to move heat around.

• passive

• active

Multiple Choice

Solar power for heating is active when

• no mechanical components are used to move heat around

• some mechanical components are used to move heat around

• it is very sunny and hot

• it produces electricity

Poll

How would you rate your understanding of passive and active solar heating?

• It makes sense, I'll need a bit of practice

• I understand it, but could not identify it right away

• EHHHH - I got the basics but need to go back and re-read the textbook and watch the video again.

• WHAT ARE WE EVEN DOING?!?!?!?

Multiple Choice

This is

• a flat solar panel

• a photovoltaic panel

• a photovoltaic cell

• a system for heating water

Multiple Choice

What does a photovoltaic panel produce?

• Heat

• Thermal energy

• Electricity

• Mechanical energy

Multiple Choice

What does a photovoltaic panel consist of?

• Solar cells

• Electrons

• A system of tubes

• Photons

Multiple Choice

Where are solar panels usually located?

• On the groud near a building

• Directed north

• On the roof - directed south

• In large sunny areas

Multiple Choice

What are solar thermal collectors used for?

• To produce electricity

• To heat water or homes

• To produce electricity and warm up water and homes

• Neither of the other options

Multiple Select

Drawbacks of solar energy are:

• it is not always available

• it is polluting

• it is still quite expensive

• all ot the other options

Multiple Choice

Where would the best location for solar power be?

• Florida
• Pennsylvania
• Maine
• Montana

Multiple Choice

How does solar energy impact the environment?

• none of these

• loss of habitat

• air pollution

• changing water levels

Multiple Choice

How can wind become energy?

• When a wind turbines changes the kinetic energy in wind to electric energy.

• When a windmill goes fast enough

• It just naturally is

• The sun heats it so it becomes solar energy

Multiple Choice

The diagram above shows a wind turbine. Which section of the wind turbine converts wind energy to electrical energy?

• blades

• generator

• rotor

• pitch system

Multiple Choice

Select the best place to collect wind

• a wind farm in a mountain valley

• a wind farm near the coast

• a wind farm at the top of a hill

• a wind farm in an empty parking lot

Multiple Choice

How do wind turbines affect the environment.

• Can harm birds, bats, and other wildlife

• Cuts the clouds which affects the water cycle.

• Hits trees around them

• They are perfect for the environment.

Multiple Select

Select the following Pros (Advantages) of using Wind Energy:

• Renewable

• It's a Green Energy

• Noise

• How they look

Multiple Choice

Solar power is different to the other primary energy sources because it

• does not require a turbine to produce electricity

• it is a renewable energy source

• it does not produce carbon dioxide

• it can be used to produce electricity or thermal energy

Multiple Choice

What is the unit for power?

• amps

• watts

• joules

• newtons
