What are you doing for the world today?
Recently we replaced our incandescent light bulbs with energy-saving ones. They are all over the house and they do a fine job lighting our way.
Way back in 1983 when we built our house we wanted it to be energy efficient. It has thick insulation, south-facing windows, and skylights for air circulation and natural daylight. Our interior/exterior stairway has done its job circulating heat and air for all these years. Our electric bill runs, on average, $45 a month.
We built our house well before the “Not So Big” books were published. But I can go through the books today and say, “Yes, we did that, yes, check,” and feel so good.
