From an article in the Kenosha News:

TWIN LAKES — Installing energy-efficient lighting and controls is expected to save a Twin Lakes grocery store more than $28,700 a year eventually.

New equipment — mechanisms on freezers, cash registers and scales, and almost 650 lights — set up the past four months at Richter’s Twin Lakes Sentry, 600 N. Lake St., should cut utility costs enough to pay for the changes in less than five years.

The alterations are part of a “Green Grocer” program offered by the Wisconsin Grocers Association. The store will receive its Green Grocer certificate at 10 a.m. today during a store tour by representatives of various involved organizations. The public is invited.

Brett Hulsey, from Better Environmental Solutions, a Madison firm administering the program, said the western Kenosha County store is one of 10 certified in the state. The stores were in the service area of Wisconsin Power and Light, one of the program’s supporters.

The program now will expand outside that area, including Racine, Hulsey said. Kenosha grocers could take part by contacting the Wisconsin Grocers Association.

The program offers a low-interest loan to grocers to purchase the energy-efficient merchandise, costing up to $100,000 on average, Hulsey said. Savings will be used to pay off the loan. After that, it will translate to a reduced cost of business, he said. BES estimated the $28,700 savings at the Sentry store.
