The European Union in its energy and climate change policy has decided to set up binding target of 20% renewables in gross final energy demand, to reduce greenhouse gases emissions by 20% and to increase the energy efficiency by 20% by 2020. It is in the process of deciding to decarbonize its power sector by 2050. A significant technology shift will be necessary to fulfill such goals, but it is already clear that technologies that will be used are available, mainly in the area of renewable electricity and heat generation, biofuels and electricity for transport, energy efficiency, especially in buildings and transportation, cogeneration, nuclear energy in those countries in which it is politically acceptable, which...
This paper gives some examples of the application of systems analysis (the examination of the elements and linkages in an interacting group of items forming a unified whole) to the issue of human development and environmental change. The various examples, taken from a report submitted to the United Nations Conference on Environment and Development (UNCED), deal with four basic human needs (food, water, energy and waste assimilation) and illustrate that: (1) it is possible to formulate holistic conceptual models of the socio-ecological system in which we live; (2) systems analysis can help us understand the constraints we face in terms of population growth, natural resources, and the assimilative capacity of the...
