THE ULTIMATE SOURCE OF ALL THE ENERGY REACHING PLANET EARTH


ULTIMATE ENERGY SOURCE GO TOP

SUN ... SOURCE OF ALL ENERGY
The sun is the source of all the energy that is available on the earth. The natural systems that convert the energy of the sun into other forms of energy that endure through time are critical for the sustainability of the planet, but poorly understood both in science and more dangerously by policy makers.
The amount of energy received by the earth from the sun
At the upper reaches of our atmosphere, the energy density of solar radiation is approximately 1,368 W/m2 (watts per square meter). At the Earth's surface, the energy density is reduced to approximately 1,000 W/m2 for a surface perpendicular to the Sun's rays at sea level on a clear day.

Huge demand ... huge supply ... Technology and economics is the problem
This report prepared in 2006 by Jeff Tsao (U.S. Department of Energy, Office of Basic Energy Science), Nate Lewis (California Institute of Technology), and George Crabtree (Argonne National Laboratory) answers a series of questions regarding the potential of the sun to supply energy to the world. The questions are drawn in large part from the U.S. Department of Energy Office of Basic Energy Science’s recent report on Basic Research Needs in Solar Energy Utilization (BES 2005). The answers are given in a format suitable for a lay technical audience, and are supplemented by detailed calculations and comprehensive references.
TPB note: While this paper is technically interesting, the idea that the world might have linear GDP growth is a catastrophic idea. On this assumption there is a very high probability there will be some sort of existential crisis that will change everything!

TrueValueMetrics (TVM) is an Open Source / Open Knowledge initiative. It has been funded by family and friends. TVM is a 'big idea' that has the potential to be a game changer. The goal is for it to remain an open access initiative.
WE WANT TO MAINTAIN AN OPEN KNOWLEDGE MODEL
A MODEST DONATION WILL HELP MAKE THAT HAPPEN
