Don'tyou wish we couldjustdo this to CFCs. Inawaywe can if we cool our buildings with natural gas. Natural gas absorption cooling equipment cools with water, rather than with CFCs, which deplete the ozone layer. Italso has fewer moving parts than conventional cooling systems, which means mainte nance costs are lower. And, because it costs much less to operate, it cuts the energy costs of cooling-by up to 50%. There's another big benefit, too. It saves electricity during the heat of the summer, when demand is at its highest. As a result, we can help our cities avoid brownouts. And help reduce the need for power plants. Best of all, we can help America balance the use of its energy resources. No doubt about it, natural gas is a high-tech, low-cost way to keep cool without CFCs. It's a cool way to help save our ozone layer, too. Clean, economical naturalgas. Think what we'll save.
