Moreover, the fossil record of these groups is scarce. RESULTS Exceptionally well-preserved fish fossils with otoliths in situ from uppermost O...
متن کاملThe Cost of Displacing Fossil Fuels: Some Evidence from Texas
Although technological progress can alter the relative costs of different energy sources, fossil fuels inevitably will be displaced as depletion raises their costs and makes them uncompetitive. They may be displaced sooner if they are taxed to internalize negative externalities. Currently, wind generation or nuclear power, supplemented by bulk electricity storage, are the most feasible alternat...
