Does concern for global warming explain support for wave energy development? A case study from Oregon, U.S.A.

Renewable energies are proposed by some as viable alternatives that can at least partly satisfy our growing energy demands while protecting the environment, especially by reducing carbon dioxide and other greenhouse gas emissions produced by carbon-based fuels. In transitioning from conventional fossil fuel to alternative energy provision, citizen understanding of the global energy problems and their causes and solutions is believed to be the key for the development of renewable energy. Numerous studies attest to the potential of wave energy development in Oregon, USA. This paper examines first, if the social basis for environmental concerns explain global warming awareness that temperatures are rising, and beliefs in its anthropogenic sources; and second, if people who are aware of the human impact on the rising global temperatures are more supportive of renewable energy development. Findings from a statewide survey, conducted in September-October 2008, reveal: 1) the majority of Oregonians are aware of the human-caused temperature rise and 2) they have a positive attitude toward wave energy development. However, the results indicate that the environmental values and concerns shaping understanding of the causes and consequences of global warming do not necessarily lead to support for renewable energy development. Policy and theoretical implications of these findings are discussed.
