Energy security, a major driver of federal energy efficiency programs in the past, came back into play as oil and gas prices rose late in the year 2000. The terrorist attack in 2001 and the Iraq war have led to heightened concern for energy security and raised further concerns about the vulnerability of energy infrastructure and the need for alternative fuels. Further, the 2001 power shortages in California, the 2003 northeast-midwest power blackout, and continuing high natural gas prices have brought a renewed emphasis on energy efficiency and energy conservation to dampen electricity, oil, and natural gas demand.
