Climate Changes is an Energy Problem

Abstract

A knowledge of the quantity of energy the world uses annually, how it is used and the effect it has on the well-being of humans is important to understanding the impact of proposed solutions to global warming. There are no substitutes for fossil fuels on the scale needed and there is nothing in sight. This report discusses the limitations of conservation, energy efficiency and renewable energies and suggests a course of action to limit the level of carbon dioxide in the atmosphere to 550 ppmv, twice that of preindustrial days, by 2100.
