In its latest monthly energy forecast, the EIA said the huge drop in demand was due to slower U.S. economic growth and the impact of high petroleum prices. The drop in U.S. oil demand helped offset a 1.3-million bpd increase in petroleum consumption in nonindustrial countries during the first half of the year. As a result, preliminary data shows that global oil consumption rose by 500,000 bpd in the six-month period, the EIA said.
