It is a while before commercial implementation but scientists have discovered a material which could speed computer processing while requiring 100 times less power. Since the projected energy consumption is projected to dramatically increase over the next 20 years, this could save a great deal of energy.
To prepare for a boom in electronic use (from 5% to upwards of 50% of energy consumption) scientists have created a material requiring 100 times less power. The material is far from implementation in consumer electronics but will help to significantly curb energy consumption.
This material is composed of composed of alternating layers of iron oxide and lutetium oxide.
