Design changes in consumption of electrical appliances.

When you cannot generate at-least conserve it. This idea prompted many scientists, engineers, to devise improved appliances for daily use. Most popular amongst them being CFL (compact fluorescent lamps). LED (light emitting diodes) are also gaining popularity in developing countries. With the rising energy costs, it has become imperative to go in for power saving gadgets. In modern urban developments, high rise buildings and transport systems are adding extra burden of electrical consumption viz, lift, escalators, metro rails. While design developments may take some time for improvements, social changes like horizontal growth against vertical may reduce this extra burden. Do you think that various nations across the globe should enact the law to restrict vertical construction favouring installations of escalators & lifts?
