Go to our website www.solarUtopia.org which features our peer-reviewed report "A Solar Transition is Possible" with important updates, including an estimate of how much conventional petroleum is needed to bring about a full solar transition in just a few decades while supplying all of humanity with the rough minimum 3.5 kilowatt/person, the necessary condition for a state of the science life expectancy and quality of life. Also test out our two calculators, one relating to our model of solar transition, the other the Energy Calculator that will connect power and energy units.
