Californians firmly support a shift to renewable energy and efforts to curtail greenhouse gas emissions, but the economic slowdown and high gasoline prices have created some public opinion cross currents, a recent poll released by the Public Policy Institute of California shows. More than 80 percent of Californians favor a wide range of state actions to trim greenhouse gases--from greater use of renewable energy to smarter land-use and transportation planning by local governments. However, only 57 percent of state residents favor moving ahead with such measures right away, while 36 percent prefer to wait until the state\u2019s economy and budget picture improves. Concern about high gas prices also has piqued public support for oil and gas drilling off the California coast. Fifty-one percent of respondents favor drilling. The institute said the response marked the first time a majority of Californians favor offshore drilling since it began asking the question in 2003. The poll also found growing support for nuclear power, with 44 percent of state residents saying they favor developing more nuclear power plants, up by 7 percent from last year at this time. Among respondents considered likely voters, the poll found 50 percent support for building new nuclear power plants. The Public Policy Institute of California survey covers a number of other questions. For instance, it asked residents to rate the state\u2019s top environmental problem and found air pollution is the top concern. The institute conducted the telephone survey between July 8 and 22. It polled 2,504 adults. The survey results have a margin of error of plus or minus two percent and have a 95 percent confidence level.
