In dealing with the nations aging power grid it has been shown to cut overall power consumption during peak use periods, to educate consumers and to sell them appliances loaded with 'smart chips'. The smart chips are programmed to cut power consumption partially when they sense a  stress, staving off future blackouts.

I think we need to go for smarter devices which are built using latest technology microchips and other devices which consumes less power and saves a lot of energy when compared to existing ones. This helps us in saving a lot of power and conserve it.
