{{B}}Save Energy at Home{{/B}} On the average, Americans waste as
much energy as two-thirds of the world's population consumes. That's{{U}}

appliances, and living and working in poorly insulated buildings. Then what can
you do to improve the{{U}} (2) {{/U}}? Buy
energy-efficient products. — Buy new appliances or electronics of the highest
energy-efficiency rating. New energy-efficient models may cost more initially,
but have a lower operating{{U}} (3) {{/U}}over their lifetimes.
The most energy-efficient models{{U}} (4) {{/U}}the Energy Star
label, which identifies products that use 20 — 40 percent less energy than
standard new products. According to the EPA, the typical American household can
save about $ 400 per year in{{U}} (5) {{/U}}bills with products
that carry the Energy Star. Switch to compact fluorescent bulbs. —

electricity costs. Set heating and cooling temperatures correctly.
— Check thermostats in your home to make sure they are{{U}} (8)
