Unplug it!- Unplug appliances that you don't use frequently. Most electronics have a standby mode that siphons energy even when not in use. Cell phone chargers, laptops, televisions, stereos — there's a whole list of items that should be unplugged when not in use. Try using a power strip for groups of electronic items. One flick of the switch and it's all off
Pay attention to packaging.- When out shopping, try to go to stores or co-ops that keep packaging to a minimum. For example, you may choose to buy the loose tomatoes rather than boxed or plastic-wrapped tomatoes. Also, take reusable bags to the grocery store. When it comes to resources, plastic is better than paper — but a reusable cloth tote-style bag is better still
Ditch bottled water.- Bottled water has a huge carbon footprint — it's bottled at one location in small plastic bottles and shipped all over. Try buying a reusable water bottle or canteen for your water. Also, a lot of restaurants have made the move from offering fancy bottled water, usually imported from an exotic source, to using in-house filtration systems that make tap water a good choice. Many plastic water bottles are recycled, but most are not, making the footprint even bigger.
Take a direct flight.- If you need to travel by airplane, try taking a direct flight when at all possible. Your impact is reduced when you take one flight, as opposed to hopping on a couple or more passenger jets to reach your final destination. You might also feel a little less harried when you arrive, because changing planes can be a real hassle
