The Boston Globe is reporting 45,000 low income families in Massachusetts will soon start getting discounted home-heating oil from a subsidiary of the Venezuelan national oil company. Venezuelan President Hugo Chavez has offered to ship 285,000 barrels of oil to Massachusetts and sell it at a 40 percent discount. The deal was arranged by U.S. Congressman William Delahunt, the Venezuelan gas company Citgo and a Massachusetts nonprofit called Citizens Energy. Nationwide home heating oil prices are expected to increase by as much as 50 percent this winter because of rising oil prices.
