Alternative Energy Research Institute Center for Advanced Materials University of Houston Sustainable Energy Development in Kazakhstan: Alternatives and Renewables Alex Ignatiev Alternative Energy Research Institute and Center for Advanced Materials University of Houston Houston, TX USA Alternative Energy Research Institute Center for Advanced Materials University of Houston What is Sustainable Development? Development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Alternative Energy Research Institute Center for Advanced Materials University of Houston Sustainable Energy Development Has Three Dimensions Environment Economy Social / Equity The Green Economy…… Alternative Energy Research Institute Center for Advanced Materials University of Houston Sustainability - The Green Economy Economic Dimension • An economically sustainable Energy System must be able to produce energy on a continuing basis, cost effectively, and in support of a growth economy Environmental Dimension • Must have a stable resource base - cannot overwhelm the environment. Deplete non-renewables only to the extent that there is investment in renewable substitutes. Social Dimension • Achieve distributional equity - adequate provision of energy services anywhere in the country Alternative Energy Research Institute Center for Advanced Materials University of Houston Doing Sustainable Energy Development requires: • Attempting to integrate (or perhaps just balance) environmental, social, and economic values ...
