Don't assume that you have to live in the desert to use solar panels on your roof. If your roof expanse gets a minimum of five hours of direct sunlight on an average day, there is likely a solar panel installation that can generate electricity for your home or building.
A solar cooker is a device which is used to cook food directly under sun light without using Gas, LPG or electricity. It’s a clean process of outdoor cooking.
Try using a clothes line to dry your clothes. This is an older idea that works just as well. Rather than drying clothes in the dryer, hang them outside on nice days. This will save energy, which in turn will save money.
