The “Almost” Forgotten Energy
Absoprtion of solar energy by atmospheric convection, evaporation and condensation of water vapor powers the worldwide water cycles and determines and drives wind streams. Solar energy converted into chemical energy via photosynthesis produces food, wood and the biomass from which fossil fuels are derived. Solar radiation and sunlight, with the addition of a variety of solar resources, accounts for 99.9% of the renewable energy on Earth! The available stores of solar energy accessible in the natural environment way beyond sufficient in comparison to current human energy needs.
Solar energy technologies and other technologies that use sunlight and secondary solar resources are critical to the current green/cleantech revolution.
