Sometimes the simplest energy saving ideas have the most effect. Drafts from ill-fitting doors and windows often cause more heat loss and wasted energy than anything else. Plus a drafty house isn’t comfortable and you tend to turn up the heat to compensate. Just fit one of these simple draft guards under the doors and solve the problem once and for all. It’s not just in winter that it is useful. Hot summer air blowing under doors will also up your air-con energy consumption. You can save up to 15% on heating and energy bills if you use one of these on every drafty door in the house. This guard stays on when doors open, gliding over the floor with the door.

If you have sprinklers on an automatic timer in your yard, it does save a lot of work and make sure that your garden flourishes even when you don’t have much time for it. However it probably wastes a fair amount of water, as your garden gets watered whether it needs it or not.
This clever green gadget is very simple. It can tell if it’s been raining. When there has been recent rainfall it stops the system from watering. This stops your garden from being over watered as well as saving valuable water and keeping down your water bills. It doesn’t need batteries and operates very simply using rainfall and water pressure. At only $14.97 from Home Depot, it is a very worthwhile and affordable investment for any green gardener.

If you have a car that isn’t used often enough to keep the battery healthy, this is the perfect solution. It is a solar car battery charger that trickle charges when set in the sunshine. It can just sit on the dashboard or in the rear window and charge the car battery whenever it is not in use. An LED light blinks to indicate the charge. If you have problems with the battery gradually draining, this will keep it topped up. However it is not intended to recharge batteries that are totally flat or compensate for faulty batteries, so don’t expect miracles!
