You can compensate for emissions when you fly by buying something called "carbon offsets." These purchases use your money to "green" your travel by supporting forest protection or tree plantings. But since the carbon offset industry is unregulated, it's important to make sure your purchase actually does what it was intended to do. Look for carbon offsets that are endorsed by independent groups like the Climate Action Reserve or the American Carbon Registry.

In addition to a swimsuit and sunscreen, consider adding these eco additions to your carry-on bag when you travel. A lightweight reusable tote bag can come in handy when you're shopping so you can skip disposable bags. A reusable water bottle can be used during the whole trip to help skip plastic bottle usage; refill it at airports, in hotels and even at restaurants. And consider bringing a multi-use bar soap that works as a shampoo and body wash so you don't use mini amenity bottles. Break it up into small pieces so you'll always have a fresh piece wherever you go.

Did you know your water heater can also take a vacation? Maybe it can't visit a faraway destination, but it can be set to use less energy when you place it on "vacation" or "away" mode. In some homes, a water heater can account for as much as 25% of your home's overall energy usage. And as always, raise or lower your thermostat depending on the season; according to the Department of Energy, set it to 85 degrees in the summer and 50 degrees during colder months.
