Re: India's Power Sector

Look at your own numbers. 20 x (10,000 sq. Km) = 2e11 sq. meters = 40 GW (assuming 20% panel efficiency). Which is about 10% of the power needed by 2030. Let's go ahead and double the efficiency due to storage, which is a huge assumption, then we get 20% of the power needed by 2030. What do you sug...

Re: India's Power Sector

Solar is some 17% efficient in actual/installed. If only solar power is installed, and assuming advances in solar, and yield is 26%, this would mean additional solar installed of 588 GW by 2030. This is simply not going to happen. The primary energy sources must come from nuclear and natural gas. I...
