Moving quickly increases efficiency but decreases safety due to low reliability in localization and environment recognition; moving slowly decreases efficiency but increases safety.
While it's best to power EVs from renewable energy sources (which are growing quickly), the efficiency of EVs makes them cleaner, producing less carbon under any situation even when they are charged using coal-fired electricity.
Halfaya boasts verified reserves of 4.1bn barrels and offers similar rewards to the Majnoon field for producers who quickly introduce efficiencies.
The cost of renewable energy is dropping quickly and its efficiency is rising sharply.
It is focusing vast resources on the low-power microprocessor market and says it is catching up quickly in power efficiency with its ARM competitors.
Even slight gains in efficiency quickly pay off as a rule of thumb, a 1% improvement knocks more than $1m off a airliner's fuel bill over its lifetime of roughly 20 years, says Ihssane Mounir, Boeing's vice-president of sales for China.
These days, however, American manufacturers of all sorts not just the big durable-goods makers are quickly improving their efficiency.Take Littelfuse, a firm that makes fuses and other equipment to protect the electrical circuits in everything from cars and mobile phones to the machines in its customers' factories.
And in a very obvious way, the lists, which replaced the boxes of 3-by-5 index cards that most campaigns depended on, quickly helped improve efficiency: the integrated data showed volunteers which houses to call and not to call, which doorbells to ring and not to ring, which voters to spend more time with and which voters to keep tabs on throughout Election Day.
For a system that goes beyond a laboratory bench efficiency quickly drops to 70-80%, which is below the 82% that theory suggests is the minimum needed if the Bell test is to be valid.A team led by Paul Kwiat of the University of Illinois at Urbana-Champaign is trying to deal with this not by reducing the losses but rather by reducing the sensitivity of the system to such losses.
Whenever this form of social activity is missing, efficiency quickly drops.
