In examining available options, the report notes that policies promoting greater domestic oil production would probably not protect U.S. consumers from sudden worldwide increases in oil prices. Although increased domestic production could decrease overall oil prices, it would encourage greater oil use, making consumers even more reliant on it. The report also notes that due to the worldwide market, oil exporters (like Canada ) are subject to the same price volatility as countries that import all of their oil (like Japan ). It concludes that policies to create incentives for consumers to use less oil would be the most effective in decreasing vulnerability to oil price volatility.
