UHERO Brief: An Economic and GHG Analysis of LNG in Hawaii
Hawaii currently meets the majority of its electricity needs through oil-fired generation – causing rates to be nearly four times the national average. In response to rising oil prices and in line with State-led action combating climate change, Hawaii is aggressively pursuing alternative sources of energy for its electric sector. Hawaii’s Renewable Portfolio Standard (RPS) states that utilities must meet 40% of electricity sales with renewable sources of energy by the year 2030; however, the remaining 60% can come from fossil fuels. Lower natural gas prices as a result of the “shale gas revolution” is in part why the State and key stakeholders are deliberating importing large amounts of natural gas in liquefied form (liquefied natural gas or LNG) for use in the electric sector.
This study builds upon past Hawaii-based LNG studies and extends the analysis by assessing both the macroeconomic and electricity sector impacts of using natural gas for power generation. We draw upon two recent studies, by Facts Global Energy (2012) and Galway Energy Advisors (2013) for price estimates. In addition to economic outcomes, this study estimates GHG emissions impacts as well as qualitatively discusses other environmental impacts related to the extraction of natural gas.
