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.

When you bring home fresh fruits and veggies from the store, it's not enough to rinse them under running water. Produce -- both organic and conventional -- should soak in a mixture of tap water and white vinegar to properly remove the chemical residue on the outside. The mild acid in the vinegar will also sanitize produce that has been touched by multiple hands from farm to packing facility to supermarket to your home. Just do a quick rinse before eating, and you're good to go!
