Assessing the potential for food and energy self-sufficiency on the island of Kauai, Hawaii
Food and energy security are major concerns in the Pacific and around the world. They are key planning priorities in Food and energy security are major concerns in the Pacific and around the world. They are key planning priorities in the state of Hawai‘i as well. Approximately 90% of energy and food resources are imported […]
Read MoreFactors Affecting EV Adoption: A Literature Review and EV Forecast for Hawaii
Electric Vehicles (EVs) reduce or negate gasoline or diesel use in vehicles through integration with the electric grid. Both plug-in hybrid electric vehicles (PHEVs)—which can draw from a battery as well as liquid fuel—and battery electric vehicles (BEVs)—solely powered through electricity—provide the opportunity for power-sharing with the electric grid and can potentially ease the integration […]
Read MoreDo Energy Efficiency Standards Hurt Consumers? Evidence from Household Appliance Sales
We examine the effect of energy efficiency standards on the clothes washers market using a constant-quality price index constructed from same-model price changes for a significant majority of clothes washer models sold in the United States between 2001 and 2011. We find constant-quality prices fell over time, while quality increased, particularly around times energy standards […]
Read MoreUp to $100 Million in Monthly Electricity Savings for Hawai’i After Oil Prices Plummet
By Karl Jandoc and Michael Roberts As of January 12, the Brent Crude Price was just a shade under $47 per barrel. The last time prices were this low was nearly 5 years ago, in April, 2009. Since crude oil and its products feed into about 90% 70% of electricity generated in Hawai’i, it is […]
Read MoreBrief: 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) […]
Read MoreAn Economic and GHG Analysis of LNG in Hawaii
Hawaii currently meets the majority of its electricity needs through costly oil-fired generation causing rates to be nearly four times the national average (EIA, 2013a). The “shale gas revolution” has led to rapidly declining natural gas prices within the continental U.S. The emergence of a natural gas market that is de-linked from oil prices has […]
Read MoreWhy Does Real-Time Information Reduce Energy Consumption?
A number of studies have estimated how much energy conservation is achieved by providing households with real-time information on energy use via in-home displays. However, none of these studies tell us why real-time information changes energy-use behavior. We explore the causal mechanisms through which real-time information affects energy consumption by conducting a randomized-control trial with residential households. The experiment […]
Read MorePV Growth in Hawai’i?
By Sherilyn Wee and Makena Coffman Public comments regarding Hawaiian Electric’s PSIP and DGIP were due last week. Here’s a recap of what Hawaiian Electric has proposed for rooftop solar PV. Hawai’i is characterized with small island electricity grids and some of the highest rates of solar PV penetration in the world. With over 10% […]
Read MoreEnergy, Backstop Endogeneity, and the Optimal Use of Groundwater
To meet the growing demand for freshwater, many regions have increased groundwater pumping in recent years, resulting in declining groundwater levels worldwide. A promising development to address these declines is technical change regarding groundwater substitutes such as desalination and wastewater recycling. However, because these technologies are energy intensive, optimal implementation also depends on future energy […]
