Analysis of world data indicates that 4000 kwh per year per capita energy is needed for the current top level of human development. About 1000-2000 kwh per year per capita is needed to get out of the worst quality of life and shortened life span. Per capita electricity usage also correlates to per capita income. Both correlate to life expectancy and quality of life.
Those nations with per capita electricity of 2,000 kWh/year (1/6 US use and an average power of 230 W) do achieve GDP of $7,500 per capita, which leads to sustainable birthrates.
Average power of 460 Watts (7 days a week 24 hours a day) would be needed for 4000 kwh/year.
If world population was 10 billion then this would be 40 trillion kwh/year.
This would be double current world electricity production and it would require more even distribution or more likely a quadrupling of world electricity production with a one third to one half portion for the developing world.
China is already at the minimum per capita GDP PPP (Purchasing Power Parity) and electricity per capita levels.
India could get there by about 2025-2030 depending upon maintaining reasonable growth rates.
About 3 billion people are still expected to be below $5000 per capita PPP in 2030
There would also need to be the goal of raising people from the $400-5000 GDP PPP per year per person level over $5000 GDP PPP per capita.
