Energy Policy and Planning Group
UHERO fellows conduct research to evaluate impacts of past and prospective energy-related policies, and engage with policymakers and stakeholders on contemporary and emerging energy issues, such as renewable energy and associated clean air goals, energy efficiency, electric vehicles, and carbon taxes.
Cost Implications of GHG Regulation in Hawai‘i
The State of Hawai‘i and the U.S. are developing greenhouse gas (GHG) emissions reduction regulations in parallel. The State requires that economy-wide GHG emissions be reduced to 1990 levels by the year 2020 and the U.S. Environmental Protection Agency is developing new source performance standards (NSPS) for new electricity generation units. The State Department of […]
Read MoreThe Costs and Benefits of Installing Solar PV
By Michael Roberts Renewable energy presents many new challenges at the system level. Before we get to that, it helps to first look at things from a homeowner’s perspective. The Homeowner’s Solar PV Decision If you’re a homeowner, and you haven’t already installed PV solar, you may want to look into doing it very soon. […]
Read MorePURPA and the Impact of Existing Avoided Cost Contracts on Hawai’i’s Electricity Sector
The United States has been trying to reduce its dependence on imported fossil fuel since the 1970s. Domestic fossil fuel supply initially peaked in 1970, and the oil crises of 1973 and 1979 accelerated domestic policy and investments to develop renewable sources of energy (Joskow, 1997). One such policy—passed in 1978 by the U.S. Congress—was […]
Read MoreIs Monopoly a Barrier to Hawai’i’s Ascent?
By Michael Roberts In 2012 Joseph Stiglitz, a Nobel Prize winning economist and Columbia University Business School Professor visited Hawaii to give the Stephen and Marylyn Pauley Seminar in Sustainability. Stiglitz discussed sustainability within the context of our depressed national economy and ongoing struggles with debt and unemployment. For our economy to fully recover, we […]
Read MoreWhy are Hawai’i’s Electricity Prices So High?
By Michael Roberts Excluding rooftop solar, Hawai’i residential consumers pay an average of about 37 cents for a kilowatt-hour of electricity. Taking refrigerators, water heaters, stoves, air conditioning and other uses into account, the average Hawai’i household uses about 18.5 kWh each day, for a monthly bill of about $205. That’s a lot, between three […]
Read MoreHawai‘i’s Environmental Response, Energy, and Food Security Tax (aka Barrel Tax)
By Sherilyn Wee and Makena Coffman The one-dollar increase in Hawai‘i’s environmental tax from five-cents since its inception in 1993 to $1.05 effective July 1, 2010 was a stepping stone in Hawai‘i’s clean energy progress. While in theory it serves to discourage fossil fuels (internalizing the negative externality), its major impact has been as a […]
Read MoreLignocellulosic Ethanol – Are We There Yet?
By Junko Mochizuki and Makena Coffman Lignocellulosic ethanol has been touted as a cleaner, next generation alternative fuel. Turning abundant resources like grasses into a transportation fuel sounds like a good idea. But, is this a viable option in Hawaii? What’s the state of technology now? What would it cost to produce it locally? Will […]
Read MoreUHERO 101.10: The Confusing World of PV
By Sherilyn Wee and Makena Coffman This UHERO 101 intends to clarify some of the rate and policy aspects of PV in Hawai‘i, and explores the two opposite driving forces of PV adoption. PV is an attractive investment in Hawai‘i where electricity rates are almost four times the national average. Rising electricity prices and falling system costs […]
Read MoreA Policy Analysis of Hawaii’s Solar Tax Credit Incentive
This study uses Hawaii as an illustrative case study in state level tax credits for PV. We examine the role of Hawaii’s tax credit policy in PV deployment, including distributional and tax payer impacts. Hawaii is interesting because its electricity rates are nearly four times the national average as well as has a 35% tax […]
