Abstract: “n the present world we are facing lot of electricity problem, lack of natural substances, depletion of fossil fuels etc., hence we should think of acquiring maximum with the limited energy resources. Green computing is the term used to denote efficient use of resources in computing .This paper mainly deals with a regenerative approach towards green computing, to enhance the power backup of battery in the laptops. This paper also throws light on regenerative technique (the heat generated by the processor is utilized) and made to harness energy”
