Question

10. Almost three-quarters of household energy use is due to the following:

• home furnaces and air conditioners

• water heaters

• washers and dryers
• lighting

For each of these uses of energy, give two reasonable ways to reduce household
energy consumption

Answer 1

Answer: Energy consumption and sustainability is important so that it remain available for future generation.

Step-by-step explanation:

1. The home furnaces are likely to require fuel like coal, which will directly emit carbon dioxide and carbon monoxide gases. These should be replaced with the electrical furnaces. The old or more power consuming air conditioners should be replaced with new ones.

2. The water heaters should be tankless so their capacity to heat more water could be possible. The water heaters should be electricity saving.

3. Washer and dryers should be water savy and electricity savy. A front-loading washing machine is useful energy saver.

4. The LED lights are more electricity saving than conventional bulbs. Halogen lights are also electricity saving.
