Overcoming Contradictions Of Climate Change In Short Time We Have
Our best hope now is an immediate return to the flow. CO2 emissions have to be brought close to zero: some sources of energy that do not produce any emissions bathe the Earth in an untapped glow. The sun strikes the planet with more energy in a single hour than humans consume in a year. Put differently, the rate at which the Earth intercepts sunlight is nearly 10,000 times greater than the entire energy flux humans currently muster — a purely theoretical potential, of course, but even if unsuitable locations are excluded, there remains a flow of solar energy a thousand times larger than the annual consumption of the stock of fossil fuels. The flow of wind alone can also power the world.
