Developments in Energy Efficiency
The future green technology holds big advancements in shaping energy efficient computers.
The new Energy Star 4.0 specifications include the 80 PLUS standards that encourage manufacturers to deploy power supplies that convert at least 80 percent of the electricity from the wall outlet to actual computing power.
Intel’s Core 2 Duo processor heralds a new era in green computing. This processor draws power only for the parts of the chip actually in use. Marvell’s processor chip uses power factor correction (PFC) to determine the amount of power any given application requires and uses this information to optimize power usage for maximum efficiency.
Such power-saving technologies are poised to become the norm in the future, and further advancements will bring forth more breakthroughs.
The development of nanotechnology also translates to greater energy efficiency. The future nanocomputer chip would be three or four levels of magnitude smaller in size and considerably faster than the ones currently available.
Another revolutionary idea that could find breakthrough in the future is harnessing the power needed for the computer to operate from keystrokes, mouse movements, and the light from the monitor.
