Any living organism relies on an external source of energy—radiant energy from the Sun in the case of green plants, chemical energy in some form in the case of animals—to be able to grow and reproduce. The daily 1500–2000 Calories (6–8 MJ) recommended for a human adult are taken as a combination of oxygen and food molecules, the latter mostly carbohydrates and fats, of which glucose (C 6 H 12 O 6 ) and stearin (C 57 H 110 O 6 ) are convenient examples. The food molecules are oxidised to carbon dioxide and water in the mitochondria
Visionary leadership, an unbridled belief in innovation, and an insistence on seizing opportunity, not just waiting for it, are fundamental to the California success story.

Authored by Kevin de León , president of the California state Senate, SB 100 also calls for an ambitious near-term target of 60 percent renewable electricity by 2030. And it would mandate 50 percent renewable electricity by 2026, four years sooner than the existing target.
