Reexamination of the feasibility of a world-wide, photovoltaic energy grid

The earth is irradiated daily by enough solar energy to fulfill all the world´s energy needs by using photovoltaic systems. Such a world-wide energy grid would eliminate costly local energy storage systems. Furthermore, such a grid could take advantage of existing national energy grids. This concept is based three factors: 1) the ability to produce enough photovoltaic panels and 2) a feasible way of providing a cost-effective means of interconnecting the multitude of photovoltaic fields exists across the world and 3) the ability of the world´s nations to reach agreements that make such a plan possible. The paper will discuss these issues.
