Chesebrough cuts fossil fuel use 15%. [Housekeeping measures at 24 plants]

An energy audit by the Chesebrough-Pond Company enabled it to cut fossil fuel use by 15 percent and its total electricity bill by 10 percent through energy-conserving ''housekeeping'' measures. A second phase, geared to capital expenditures for energy conservation, is expected to lower consumption 10 to 15 percent by 1980. Immediate savings were effected by a reduction in the lighting, heating, and ventilating systems, more efficient combustion in steam boilers, and off-peak load scheduling. Air is recycled in the plants. The company's policy is to double output while increasing energy consumption only one and a half times through improved efficiency. A sample audit is under way at the company's Ragu food plant at a cost of $2,000. Results will determine if all 24 company plants should receive similar audits by the Energy Appraisal Associated of Rolling Meadows, IL. A consultant from National Electric Service, New York, oversees utility charges and billings for a share of the savings. (DCK)
