Kitchens are an important place to make savings, especially with a range of environmentally-friendly products on offer, one expert has suggested. Author of Good Green Kitchens Jennifer Roberts remarked that energy saving in the kitchen need not be an expensive endeavour, according to the HGTV website. She said If you grow some of your own food or buy as much locally grown produce as you can, youre more than halfway there in terms of having a green kitchen.Purchasing your own vegetables - which could be washed and easily prepared in the kitchen sink - is the most important step to eating sustainably, Ms Roberts added. Those who use a dishwasher instead of a kitchen sink may be able to cut costs by ensuring they buy models that use the least energy and water. People that do prefer to do their washing in the kitchen sink may benefit from a Franke Triflow water filter to fit to their kitchen taps, which is designed to purify water through hot and cold mediums.
