"These new laws will help free Hawai'i from the grip of our foreign oil addiction," said Jeff Mikulina, executive director of Blue Planet Foundation, which lobbied for the measures.

Mikulina and others are still waiting to see whether Lingle signs HB 1271, which would increase the tax on a barrel of imported oil by $1. The hike is expected to generate more than $30 million annually to fund clean-energy and food-security initiatives in Hawai'i.

The legislation received widespread support from legislators, environmentalists and clean-energy advocates but was opposed by those who said it would increase Hawai'i's high cost of living, mainly through higher gas prices.

Although clean energy is one of Lingle's priorities, her administration opposed the barrel-tax bill during the session because of the belief that the increase would be passed on to consumers in the midst of a recession.

A Lingle spokesman Friday said the governor still is reviewing the bill. She is required to notify legislators by Tuesday what measures are on her list of potential vetoes. Lingle has until July 15 to sign or veto the measure. The three bills she signed last week take effect Wednesday.

In addition to setting renewable-energy thresholds for the power companies, HB 1464 would require homeowners selling their residences to disclose the property's electricity costs for a recent three-month period to prospective buyers.

Last week's approvals came on the heels of two other energy measures the governor previously signed. One (SB 1260) removes a current loophole allowing large air polluters to pay less for their emissions, and the other (HB 1270) is designed to stimulate demand for renewable energy.
