Who are Driving Electric Vehicles? An analysis of factors that affect EV adoption in Hawaii
This study uses data on EV registrations by zipcode in Hawaii to analyze a variety of demographic and transportation factors that might affect EV adoption. After controlling for population and gasoline prices, zip codes with higher income and educational attainment are associated with higher levels of EV adoption. Longer commute times also influence EV adoption […]
Read MoreA Pocket Full of PIMs
By Michael Roberts In the arcane parlance of utility regulation, PIMs are “Performance Incentive Mechanisms.” This is where we’re headed because, slightly against my expectation, Governor Ige recently signed SB 2939, a bill unanimously passed by the legislature that requires that the Public Utilities Commission: “…establish performance incentives and penalty mechanisms that directly tie an […]
Read MoreVariable Pricing and the Cost of Renewable Energy
On a levelized-cost basis, solar and wind power generation are now competitive with fossil fuels, and still falling. But supply of these renewable resources is variable and intermittent, unlike traditional power plants. As a result, the cost of using flat retail pricing instead of dynamic, marginal-cost pricing–long advocated by economists–will grow. We evaluate the potential […]
Read MoreShould regulators fear bond-rating agencies?
By Michael Roberts It seems that our political and administrative leaders worry about the bond rating agencies. Their fear is understandable. The cost of capital looms large in all manner of infrastructure projects, and the cost of that capital depends on how risky investors perceive repayment to be. The cost of capital also looms large […]
Read MoreDeterminants of Residential Solar Photovoltaic Adoption
Hawaii is a leader in distributed solar photovoltaic (PV) adoption. It has the highest rate of PV-based electricity penetration in the U.S. and rivals global front runners. The policy impetus towards large-scale adoption of renewable energy comes from the Renewable Portfolio Standard, with a target of 40% net electricity sales from renewable sources by the […]
Read MoreResidential Battery Systems and the Best Time to Invest: A case study of Hawaii
Battery storage is a complementary technology to intermittent renewable energy sources. In particular, it pairs well with solar photovoltaic (PV) systems to capture excess solar generation during daylight hours and to draw energy from it when needed. Technological advancements and rapidly declining costs have made batteries more economically feasible for households, especially in the state […]
Read MoreBringing together energy and climate change policy
By Sherilyn Wee We hear a lot about Hawaii’s Renewable Portfolio Standard (RPS) which requires 100% of the utilities’ net electricity sales to come from renewable sources by 2045. Subsidies, rapidly declining solar panel costs, and high electricity prices have led to the proliferation of distributed rooftop solar photovoltaic (PV). By the end of 2016, […]
Read MoreGoverning Green Power: Realigning Institutions To Fit New Technologies
The “Governing Green Power” conference was held in Honolulu at the University of Hawai`i at Mānoa, March 28-30, 2017. The motivation for the conference was the recognition that energy technologies are changing faster than energy-related institutions — the organizational structures, market mechanisms, and regulatory incentives that govern power generation, transmission, distribution and storage. The complex […]
Read MoreA review of the current state of research on the water, energy, and food nexus
The purpose of this paper is to review and analyze the water, energy, and food nexus and regions of study, nexus keywords and stakeholders in order to understand the current state of nexus research. Through selected 37 projects, four types of nexus research were identified including water–food, water–energy–food, water–energy, and climate related. Among them, six […]
