Usually the ads on the subway are just white noise for the eyes. I might try and decipher a Spanish ad now and then, but my eyes glaze over when it comes to yet another sign for a doctor or lawyer.

But an ad directly above where I was standing on a New York City N-train caught the eyes of my husband, Paul. Con Edison, our local electric company, has a series of ads highlighting specific ways to save energy, money, or often both. Take the tip Paul noticed:

If you use glass or ceramic in the oven, you can lower the temperature by 25 degrees and still get the same results.

Who knew? Not me. But if it's good for the environment and my pocketbook, it's good by me.
