Per capita electricity use / day
USA : 40 units (of which 36% is residential)
EU : 20 units (35% is residential)
China : 7 units (15% is residential
India : 2.5 units (!) (20% is residential)
World : 8 units (27% is residential)
Take a look at this very interesting graph..
A good straight-line fit gives us a GDP of 40 cents for every unit of energy (total, not just electricity) consumed. I know there are some implicit, non causal relationships, but this is a wonderful number to remember.. say for India to reach a per capita GDP of $10000, the annual per capita energy use could be close to 25000 units. Another way of looking at it (a Nobel winning Stanford Prof says this): For (roughly) every dollar spent on energy, you typically generate 4 dollars of GDP. Quite remarkably, this number is more or less the same across all type of economies including for the big bad US of A. Americans account for 25% of the world's energy consumption and account for 29% of its GDP. In other words, there are no shortcuts, at least so far.
India better be building one nuclear reactor every month for the next 20 years ?
Daily energy use of the world : 360 billion units
Global power consumption : 15 Tera watts
