Abstract

The major part of the electricity production is generated on fossil base. The renewable generation emits far less CO2. In this paper we investigate a vision how all the electricity need could be supplied by solar PV plants.
Our technical vision is a solar belt surrounding the earth near the equator. If we calculate the power capacities a narrow stripe could produce all the electricity need for the whole World. At first sight we do not store the energy but try to produce it on the sunny side and transmit to the dark side ‘on-line’ the necessary amount. We plan for this long distance/high energy transmission UHVDC network.
We made a bulk calculation about the availability of this approach and we find on-line PV supply of the World technologically feasible. If we don’t have a “green field investment” only with PV solution but we start from the existing situation and we build more PV and we create a large East-West transmission system, it can alleviate the present energy problems.
