Computer Energy Efficiency Doubles Every 18 Months

Comments Off on Computer Energy Efficiency Doubles Every 18 Months

A new study done by an engineering professor at Stanford University has found that the energy efficiency of computers doubles roughly every 18 months, and has done so since the very first general purpose computer, the Electronic Numerical Integrator and Computer (ENIAC) that was built in 1956. With help from Intel and Microsoft, Professor Jonathan Koomey was able to gather information about computing devices from 1956 until now and with this new finding, Koomey is revising and improving Moore’s law — the observation that computer processing power doubles every 18 months.  Fortunately, the things that contribute to that power improvement (reducing component size, capacitance and communication time between them) also increase energy efficiency. This finding has great implications for the future of computers and battery-powered devices.  As we constantly increase the performance power of computers and gadgets, we’ll be improving their energy efficiency as well — a much needed trend as we become more reliant on our portable devices. Also, theoretically, we’re far from the limit of how much electricity we can save.  In 1985, physicists projected that we could improve computer energy efficiency by a factor of 100 billion and since then we’ve only hit a factor of about 40,000. via MIT Tech Review

Photo via the Telegraph There are more protests in China every year–an estimated 100,000 of them–than any other nation. Most of these are orchestrated by the poor , demanding human rights and economic equality–and most are stamped out and covered up by the Chinese government. But now the middle class is getting fed up, too.
