Moving Beyond Oil

摘要

Worldwide angst over oil has enormous implications for hydropower. The recent run-up — the rising tide — of oil prices makes electricity production increasingly attractive. That's because, as an alternative to oil, many tasks can be done as well or better using electricity (and little oil is used to make electricity). Electricity's "big three" energy sources are coal, hydro, and nuclear — coal is dominant, and hydro and nuclear each produce about 17% of the world's electricity.
