The tool is expected to help customers understand their energy usage by asking questions specific to their own apartment, condo, house or small business.

The company said that MyEnergy Analyzer, at www.my.dteenergy.com, has two parts, a bill-analyzing tool and an energy-efficiency tool. It provides customized energy-efficiency recommendations and will show the customers how much they can expect to save if the recommendations are followed, according to DTE Energy.

Joyce Hayes-Giles, senior vice president of customer service at DTE Energy, said: We’re offering this to our customers because the information goes beyond what we can offer on our paper bills. MyEnergy Analyzer can provide immediate answers to energy-related questions and identify factors that cause energy bills to go up or down.
