In the field of sustainable energy production and consumption the World Summit in Johannesburg has not fulfilled expectations. Official documents did not contain any concrete aims, e.g. supporting of renewable energy resources that could be a significant aid in the sustainable development or removal of subsidizing of fossil fuels. As an outcome of the Summit the world will base its further development still upon permanently diminishing sources of fossil fuels while development of renewable energies will be retained to noncommittal initiatives of individual countries and organizations.
