Dear Eric,  The National Academy of Sciences may change its original report on fuel economy standards.  Washington Correspondent Alison Kosik reports, those on the panel say they may have miscalculated the numbers, overestimating the fuel efficiency gains possible for the next generation of vehicles.  We'll have an update on the Academy's announcement on Friday from the Washington bureau.     Major players that could be effected by energy legislation are meeting Friday behind closed doors to discuss emissions issues.  Senator Jim Jeffords, (I)-Vermont, is leading the meeting, which could help craft his multi-pollution legislation.  We'll have reaction to the negotiations on Capitol Hill from the Washington bureau tomorrow.     Jacobs Consultancy Managing Director Karl Bartholomew says multiple requirements being placed on boutique fuels could make them so expensive, many small U.S. refineries may be put out of business.  We'll bring you the details from the Houston bureau on Friday.     Following delays and computer problems during the Texas Pilot Program, ERCOT is switching more Texas customers over to its computer system.  ERCOT COO Sam Jones talks about the switch from the Houston bureau on Friday.    West Coast Bureau Correspondent Kym McNicholas talks with Phoenix Consulting's Susan Schneider on Friday.  Schneider will discuss the DWR rate agreement, California ISO's budget and electricity market regulations.   We'll also have a report from the West Coast bureau on this winter's forecasted natural gas supply, as well as PG? and Southern California Gas Company's efforts to improve California's intrastate pipelines.  Kym also says we may hear more from federal court on the California PUC/Southern California Edison rescue plan.  We'll have all this from the West Coast bureau on Friday.
