28. natural gas Section 25.2 Alternative Energy Resources

1. House A uses passive solar heating, and house

B uses active solar heating.

2. walls and floors made of heat-collecting and

heat-retaining materials such as concrete, adobe,

brick, tile, and stone; heavy insulation in walls

and around windows

3. collectors that absorb solar energy and fans or

pumps that distribute that energy; solar panels

on roof for heating water

4. Passive solar houses cost 30 to 40 percent less

to operate than do traditional homes.

5. Solar energy is free, and it does not cause any

kind of pollution.

27. geothermal energy

28. nuclear fission Section 25.3 Conservation of Energy Resources

1. improve energy efficiency and increase use of

locally available, renewable energy resources

2. Possible responses: Use more energy-efficient

vehicles, such as hybrid and electric cars.

Pass laws that lower speed limits. Use public

transportation. Use carpooling. Work at home.

Ride bicycles.

3. Power-generating plants capture the heat

created during the process and use it to operate

electrical devices in the plant or to warm the

building.

Manufacturers make a greater effort to recycle

and eliminate unnecessary packaging.

4. Possible responses: Use energy-efficient

lightbulbs. Use more-efficient insulation. Use

energy-efficient appliances. Install new

windows.

Use passive and active solar heating.

5. Put in energy-efficient insulation. Use energy

efficient construction materials. Design the

house to use solar energy.

6. Energy resources on Earth are interrelated;

people need to manage Earth’s natural resources

to meet current and future needs that affect the

entire planet.
