 ===== High levels of energy efficiency can be achieved in other sectors, too =====
-  * With the 1-litre car, over 75 % of the fuel can be saved (without restricting driving comfort – such a car will soon be available on the market)
+  * With the 1-litre (14 kWh) car, over 75 % of the fuel is saved (without restricting driving comfort – a good electric car has such a high efficiency)
-  * With an LCD monitor about 70 % of the electricity consumption is saved in comparison with old CRT monitors; LED-monitors will be better again and electronic ink will be even better, there is almost no energy consumption remaining with such a screen from a modern e-book-reader.

-  * 75 to 80 % of the electricity consumption can be saved by using fluorescent lamps or LED-lights available on the market
+  * 75 to 90 % of the electricity consumption can be saved by using fluorescent lamps or LED-lights available on the market; the latest developments are es good as 210 lm/W.
 > Energy efficiency means substituting energy consumption by intelligent, innovative products and clever process management; in short: **"brains instead of brawn"**.

 The computer sector could do more to improve the energy efficiency of products. The possibility of **maintaining the full performance of a PC including the monitor and peripherals while using a continuous output of a mere 5 to 10 watts**, has been demonstrated by the **"One Laptop Per Child"** project.
-And that's only one-tenth of the normal output of personal computers today. Maximising energy efficiency helps minimise the energy otherwise needed.
