> The main problem of energy is batteries. The main problem of energy is cost, NREs, capex, and long term support. The Big Energy (gigawatt scale powerplants,) works well on big scales. But 9 out of 10 countries don't have that. Big economy, big population, big industry, big infrastructure — you need all 4, or it doesn't work. Solar is extremely efficient at small scales if you think of capital costs. A single panel atop of a tent in the desert is just few percents behind a gigawatt scale solar powerplant in efficiency. Now think of any 2 stroke generator you see in a 3rd world country. Costs many times more for the power if you look at ones capable of 24/7 operation. Heavy duty diesel ones are even more so.
