All biological life on Planet Earth is regenerated by star energy-- and overwhelmingly by the star Sun’s radiation. The Sun radiates omnidirectionally 92 million miles away from Earth, with only one 2-billionth of its total radiation impinging upon Earth. The radiation arrives at a rate of two calories of energy per each square centimeter of Earth’s sunside hemispherical surface per each minute of time. About half of that is reflected back omnidirectionally to Universe. The other half, i.e., one calorie-per-minute-square-centimeter, is impounded by our planet’s biosphere in ways known to humans and in ways making them available to human use granted humanity’s permitted comprehensive, ecologically considerate, employment of its inventive capabilities and spontaneously cooperative potentials.
