According to estimates, by 2014 there will be around 2 billion computers in use in the world. The energy consumption of such an amount is equal to the energy required for a country like India for a whole year. The European Union estimates that the consumption of electric current in standby mode in various devices reaches up to about 10% of the consumption in the countries of the Union. In a short time, with the proliferation of computers and mobile devices in Europe, their annual electricity consumption will reach the level of the aggregate consumption of Austria, the Czech Republic and Portugal together.
