General tips
Buy Seasonal Food : If you're eating foods out of season, it's likely that they have come a long way - try to eat food that is both locally produced and can be found at that time of year, locally!
Microwave Tip : Use your microwave as often as possible in the summer. You'll be more comfortable and save on air conditioning costs.
Buy Local Food : The most local food of all comes from your own garden. Plant a new garden, enlarge the one you already have, or extend your growing season by using row covers and cloches.
