UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The diminishing supply of petroleum and natural gas has induced many concerned citizens as well as many interest groups to study energy problems. Based on different sources of information and various degrees of economical consideration, conflicting conclusions have been reached. To help resolve this situation, a systems study was conducted. The available statistics on the supply and demand of energy were examined. The resources of nuclear energy, fossil fuel, and renewable energy sources were analyzed. Considerations were weighted equally on energy content, resource availability, existing technology, and consumer economics as well as on the impact of ecology and sociology. The …
