Saving electricity is a major concern for domestic and industrial units. We always try hard to save electricity in many ways to reduce our electricity bills, but due to some known and unforeseen circumstances our efforts do not normally transform in saving electricity. Adding to our woes we may at times forget to switch off electrical gadgets when we are not using them, especially the AC’s, which not only results in mounting electricity bills, but also forget the fact that we are wasting a resource which is of National Importance.
