The best way to conserve natural resources and save money is to conserve energy. The cheapest unit of electrical power is the one we don’t need to generate at all. So energy efficiency should be our number one priority. Think of it as our first, best fuel. We can all generate it.
You don’t need a special contractor to make your home more energy efficient. In most cases, it takes less than two hours to perform a few home "hacks" (detailed below) that can save anyone, from dorm-dwellers to apartment renters to homeowners, upwards of $135 a year.
THROWING SHADE: A new study from The Nature Conservancy suggests that planting trees in cities can result in cooler temperatures, which can save up to 48 billion kilowatt-hours of electricity annually and avoid up to 13 million tons of carbon dioxide emissions each year, reducing air pollution for millions of urban residents.
