Material things doesnt matter much , what matters is Energy and Intelligence that takes you to the matter that matters most. More about this "saying" by me in my later posts.
Oil equivalent of energy consumed is - perhaps about 2000 kg of oil - or about 2500 liters of oil in 2014. considering about 10 to 10.5 Kwh per liter of oil, the consumption is about 25,000 KWH units of Electicity per annum, or aboout 2100 units per month , or about 70 units per day. This is perhaps all inclusive, Includes travel, your public transport, the consumption of power for production by the industry which produces them, The energy for the construction of your home, your appliances, all inclusive.
Average solar insolation is about 5kwh per day, even at 40% conversion efficiency, that comes to about 2 Kwh per day require atleast 35 sq.m of land per person . for 7 billion people , about 0.245 million sq km is required. Compared to India's area - about 3.3 million sq KM, it is roughly 7.5%.
Indian population being 20% of global population, India would need 1.5% of its land to meet the country's present energy needs from purely solar @40% efficiency. @ 20% efficiency it willl be 3%. Wow.
Compare this to the percentage forest cover in India at 23%. Looks meagre, But this doesn't look scalable, if we need to increase the present energy consumption by 100 times, Just as we had increased the consumption of bandwidth over the last 10-20 years. Then 150% of India's land is needed for our consumption @ 40% efficency. Not possible . So is nuclear fuel the only answer. Or am I simply dreaming of a 100 fold increase in energy consumption per capita!!!!
