A 12,000 solar cell aircraft was able to fly for 19 hours without backup fuel, all its energy derived purely from the sun and stored in lithium-ion batteries. The landmark flight signals that solar is now capable of vesting control of a significant share of the energy market that fossil fuels still control.
On April 15 this year, Germany, a country not known for sunny skies, generated a new peak of 22.68 gigawatts of solar output at noon, and a grand total of 167 gigawatts over a span of 12 hours throughout the day, approximately the same as 34 tonnes of oil, and was 12 percent of total German electricity consumption.
Over in Thailand, the government has started investing in solar with a 73 megawatt solar farm finished in 2011, but progress is still slow. If Thailand, a much sunnier country near the equator, can reach the same solar capacity as Germany, it is likely the Thai people will not fret over energy shortages any time soon.
