Makers of single-pod coffee makers have recently introduced a "recyclable" cup that can be tossed into the recycling bin. But what they don't disclose is that users of these cups must first peel off the aluminum foil top, empty out the used coffee grinds and then toss the plastic portion of the cup into the recycling bin. The reality is, the majority of people (even with the best intentions) will toss the whole thing -- cup, grinds and lid -- into the bin. "Recyclable" does not always mean "eco-friendly," so ditch the disposables and make coffee using a French press or drip-style coffee maker instead.

When installing outdoor lightbulbs in climates that can have weeks of below-freezing temperatures, it's key to choose energy-efficient LED lightbulbs. Even though there are compact fluorescent bulbs (in floodlight styles) on the marketplace, they can fail to work in cold climates. LED bulbs are designed to work effectively in all types of temperatures, both hot and cold, so you'll be able to see even as the temperature drops.

When traveling, if your destination is less than 300 miles away, it's best to avoid short-haul flights and opt for a different mode of transportation. According to the World Wildlife Fund, short-haul flights are the least fuel-efficient mode of travel. Choosing to drive or going by bus or train are the most eco-friendly ways when you don't have too far to go. When you do have to travel far, choose planes with the highest possible occupancy rates, which means they are the most fuel-efficient.
