A coalition of 38 businesses and environmental groups, ranging from the Whirlpool Corp. to the Natural Resources Defense Council, called on President Clinton this week to do more to promote energy efficiency. Clinton recently announced that the government will tap into the Strategic Petroleum Reserve to help lower home heating oil costs, but the coalition urged him to follow up this move by pushing for new tax incentives for buyers of energy-efficient products and increased government investment in renewable energy and clean technologies. In a letter to the president, the coalition also called for $200 million in additional government funding to help low-income people weatherize their homes and for more research and development on ways to reduce consumption of oil and natural gas.
