The goal of the GES Reference Solution is to chart a path to a world that enables all ten billion people to live in freedom with adequate prosperity in social balance, an intact environment and a stable climate system in the period 2050 to 2070. The guiding idea is energy prosperity for all through innovation and the market, instead of managing energy scarcity. The solution is embedded in the regulatory framework of a global market economy with environmental and social guard rails, which also forms the basis of the United Nations 2030 Agenda (Sustainable Development Goals). The GES reference solution is composed of twelve building blocks as presented in a preliminary version of the Executive Summary. Prof. Franz Josef Radermacher explained the GES Reference Solution in a lecture he gave in Ulm on the 9th of May.
