GLOBAL PHOTOSYNTHESIS CALCULATION II. “World energy consumption is currently about 450 exajules per year (EJ/yr), or 125,000 terawatt hours. Photosynthesis, the ultimate source of our oxygen, food, and fossil fuels, is a great invention of nature that has been deployed on Earth for about 2 billion years. In its present technologically unenhanced form, photosynthesis globally already traps around 4,000 EJ/yr of solar energy in the form of biomass.””
