An environmental commentator has offered some tips on how to save energy and water in the kitchen over the winter season.The creator of the Daily Kos blog lists some useful and practical steps for reducing consumption at what can sometimes be an indulgent and occasionally wasteful time of year.Among the pieces of wisdom are hints on cooking efficiently, which could see a kitchen user not overfilling the kettle or pot in order to keep water use to a minimum.Homeowners are also advised to consider the way they wash up, whether its by hand or in a dishwasher, to make sure they use their resources as efficiently as possible.The importance of doing this cant be emphasised enough, says the blogger.Another key way in which kitchen users can keep the environmental impact of their kitchens to a minimum is to use a food waste disposer such as those from design-lead manufacturer Franke.
