The continuous increase of the world population in the developing countries is escalating the requirements for the energy and raw materials. These goods represent the fundamental needs to ensure the sustainable human development. The limited availability of the resources makes urgent adoption of suitable strategies in the energy sectors and raw materials to prevent them from the social and economic. The fulfillment of the basic human needs is the food, environmental quality and health requires a large amount of energy. This is due to not only to the economic reasons and the political choices, but also to the technological limitations. The real problem is to know when science and technology will be able to answer the open questions regarding the renewable energy and materials allowing them to adopt on a global scale of the decisions before the depletion of the traditional energy sources which becomes an unsolvable problem [BTM, 2002]. The science and the technological development are the key tools for achieving these objectives. Therefore they must recognize that the progress of scientific research and its applications represents the primary way to solve the major human problems In those countries, the lack of infrastructure and human resources with adequate scientific knowledge precludes the possibility of carrying out innovative research or the adopting technologies derived from the developed world. The replacement of oil with new energy or raw feedstock should not be our primary goal. Our reasonable objective must be to maximize the source diversification. There are many sustainable solutions in the energy sector, but only a few are competitive with the use of fossil hydrocarbons. Then, the distance between the sources of energy and raw materials and the cities where the electricity and the products that are used requires huge investments for distribution and transportation. The investments for the production are related to the exploitation of energy resources. The great attention is turned towards the hydrogen economy [Christensen, 2000]. It must be clarified immediately that the hydrogen is not an energy source but it is an energy vector, and it can be considered renewable. Its utilization in fuel cells leads to water as a final product, and hydrogen can be produced from water using solar energy. However today the hydrogen is mainly produced from methane. In case of the science and technology with their limitations is the only solution for the problem.
