Cellulosic Ethanol: Securing the Planet Future Energy Needs
Bioenergy is fairly recognized as not only a necessity, but an inevitable path to secure the planet future energy needs. There is however a global consensus that the overall feasibility of bioenergy will require an integrated approach based on diversified feedstocks and conversion processes. As illustrated in the Brazilian experience, the thrust of any bioenergy program should be centered on th...
متن کاملWorld Energy Outlook : a Comparative Study
Differen world energy outlook with different horizons (2035, 2040 and 2050) show that demand for primary energy will increase. The energymix in 2050 will mainly be fossil based although the share of theses fuels will decrease. Accorging to some forecasts, energy consumption will increase more than 50 percent during next 30 years which most of this growth belongs to non-OECD countries. In supply...
متن کاملCERN: Past performance and future prospects III. CERN and the future of world high-energy physics
In a series of three papers. we attempt to evaluate the past scientific performance of the three main particle accelerators at the Geneva-based European Organjzation for Nuclear Research (CERN) over the period since 1960. and to assess the future prospects for CERN and its users during the next ten to fifteen years. We concerned ourselves in the first paper (Paper 1 Martin and Irvine [29]) with...
متن کاملConsiderations for the Selection of Suitable Energy Sources Needed for Future World-Wide Energy Consumption
The major part of worldwide energy production concerns fossil energy. Therefore, concomitant carbon dioxide production is a problem. What are suitable alternatives? Here we present considerations for selection of energy sources needed for future worldwide energy consumption. Plants are collectors and converters of sunlight and are indispensable in the carbon cycle. This cycle converts sunlight ...
