The use of the eco-friendly and free solar energy is very quickly gaining acceptance as an alternate electricity source against the traditional electricity produce by the environment degrading coal and its products. Solar lighting can be used to light up the yard outside the house at night. It is cost effective and installation costs are the only costs to be incurred. They have no operational costs and a significant drop in the monthly bill is sure to be noticed.

Like heating, solar heating is a method of applying solar power for heating water for domestic purposes. As expected, the running costs for this as well are nothing but wiping off the dust from the pipes.
