Reappraisal of energy supply-demand in 2050 shows big role for fossil fuels, nuclear but not for nonnuclear renewables

摘要

There are a number of different energy scenarios currently beging proposed, but most industry analysts forecast that world primary energy demand will double by 2030, climbing to 18 gigatonnes of oil equivalent (Gtoe)/year from 9 Gtoe in 2000, and roughly triple to 25-30 Gtoe by 2050. According to these projections, by 2050 fossil fuels will account for no more than two thirds of all energy consumed vs. 85% today.
