As electronic products more and more energy to be more effective, there is certainly a long way to go until some laptop batteries products may be a technological advance on the rising power. Take a look at PDP (plasma display panel) TVs - which are thinner than the old CRT (cathode ray tube), models and could provide a better framework, but in many cases more than the amount of energy they use is replaced - hardly a step forward when it comes to the amount of energy that reduce our use.
