Which of the following are considered advantages of solar energy? (Select all that apply)

• Unlimited resource

• No pollution during operation

• Dependent on weather (this is a disadvantage, not advantage)

• High greenhouse gas emissions (incorrect, no emissions during operation)

Which of the following are disadvantages of solar energy? (Select all that apply)

• Weather-dependent energy generation

• High initial costs (though decreasing)

• Produces large amounts of air pollution (incorrect, solar has no pollution during operation)

• Requires sunlight availability during daytime

Passive solar design involves:

• Using collectors and pumps to distribute heat

• Using mirrors to concentrate sunlight for electricity generation

• Using solar panels to convert sunlight into electricity

• Using building design to capture sunlight for heating

Active solar water heating systems:

• Use mirrors to concentrate sunlight

• Employ collectors and pumps to move and distribute heat

• Directly convert sunlight to electricity without moving parts

• Rely solely on building materials to absorb heat
