Looking for Ways to Help Save the Earth? Here Are Some Suggestions

-- John Peters, Annandale

I am getting fed up with stores that leave their front doors wide open, especially in summer. Do the owners actually think that, absent the door being open, we wouldn't realize that the stores have air conditioning?

For several years, Anne Beers Elementary School, 3600 Alabama Avenue SE, has run its window air conditioners 24/7 throughout the summer, although the school appears vacant. I wonder how many other D.C. schools do this, too. I believe this is an incredible waste of energy and money.
