Making an Optimal Plan for 100% Renewable Power in Hawaii

The State of Hawaii has adopted the unprecedented goal of building a 100 percent renewable power system by 2045. This report identifies some of the central challenges in achieving this goal and uses the SWITCH power system planning model to identify solutions to these challenges. A 100% renewable power system must balance electricity supply and demand on two main time scales: diurnal (providing enough power each hour of the day) and seasonal (providing enough total energy on each day of the year). The diurnal balance could be achieved by installing large amounts of primarily solar production capacity, then using batteries, demand response, biofuels or hydrogen production to shift power production and/or consumption between day and night. The seasonal balance may be more challenging. Energy demand during days or weeks with low sunlight could be met by building extra solar and wind capacity, using biofuels, or using hydrogen produced during sunny months. Demand response will likely be less expensive than the other options for day-night energy balancing, and customer-sited solar may be competitive with utility-scale solar; consequently electric utilities may need to become energy integrators and market managers, rather than bulk power providers.It is unclear how much biofuel the State could use without compromising other environmental and energy independence objectives; consequently hydrogen energy storage merits serious consideration. SWITCH or similar models can be used to identify optimal long-term plans; however, a new incentive system is needed to encourage the State's utilities to develop and implement such plans, regardless of who will own the generating equipment.

Annual Hawaii Forecast: Expansion Will Continue, Despite Global Challenges

This year has turned out a bit better than anticipated, and prospects remain good for 2016. Next year will see some easing of visitor growth, but no retreat from the high levels of activity that have built up in recent years. The construction expansion will continue, and tightening labor market conditions will support income gains. Arrayed against this positive outlook are important global challenges, ranging from the surging dollar to Chinese slowing and renewed terrorism threats.

Methods of the Water-Energy-Food Nexus

This paper focuses on a collection of methods that can be used to analyze the water-energy-food (WEF) nexus. We classify these methods as qualitative or quantitative for interdisciplinary and transdisciplinary research approaches. The methods for interdisciplinary research approaches can be used to unify a collection of related variables, visualize the research problem, evaluate the issue, and simulate the system of interest. Qualitative methods are generally used to describe the nexus in the region of interest, and include primary research methods such as Questionnaire Surveys, as well as secondary research methods such as Ontology Engineering and Integrated Maps. Quantitative methods for examining the nexus include Physical Models, Benefit-Cost Analysis (BCA), Integrated Indices, and Optimization Management Models. The authors discuss each of these methods in the following sections, along with accompanying case studies from research sites in Japan and the Philippines. Although the case studies are specific to two regions, these methods could be applicable to other areas, with appropriate calibration.

Forecasting in a Mixed Up World: Nowcasting Hawaii Tourism

We evaluate the short term forecasting performance of methods that systematically incorporate high frequency information via covariates. Our study provides a thorough introduction of these methods. We highlight the distinguishing features and limitations of each tool and evaluate their forecasting performance in two tourism-specific applications. The first uses monthly indicators to predict quarterly tourist arrivals to Hawaii; the second predicts quarterly labor income in the accommodations and food services sector. Our results indicate that compared to the exclusive use of low frequency aggregates, including timely intra-period data in the forecasting process results in significant gains in predictive accuracy. Anticipating growing popularity of these techniques among empirical analysts, we present practical implementation guidelines to facilitate their adoption.

UHERO State Forecast Update: Except for Weather, Outlook Shines

Hawaii’s economic outlook continues to look bright. Tourism is pushing toward new records, and the construction upswing is building in strength. The overall expansion remains solidly on track, delivering better labor market conditions and the prospect of further household income gains. Still, in the midst of this hot and soggy summer we are pondering some ominous clouds forming out on the horizon.

Facebook-to-Facebook: Online Communication and Economic Cooperation

Communication is often critical for economic cooperation and enhancement of trust. Traditionally, direct face-to-face communication has been found to be more effective than any form of indirect, mediated communication. We study whether this is still the case given that many people routinely use texting and online social media to conduct economic transactions. In our laboratory experiment, groups of participants communicate either (i) face-to-face, (ii) through the most popular online social network - Facebook, or (iii) using text messaging, before participating in a public goods or a trust game. While people talk significantly more under traditional face-to-face, discussions through Facebook and text messages prove as effective as face-to-face communication in enhancing cooperation and increasing trust. For all three media, discussions that focus on the game or use more positive emotion words are correlated with enhanced trust. It appears that young American adults are now just as adept at communicating and reducing social distance online as they are in person.

Electric Vehicle Lifecycle Cost Assessment for Hawaii

This study develops a model to estimate the total cost of ownership of electric vehicles (EVs) in comparison to similar internal combustion engine (ICEVs) and hybrid electric vehicles (HEVs). The model includes issues related to purchase/finance, insurance, maintenance, resale value, future fuel prices and access to solar photovoltaic (PV). It also estimates the impact of proposed EV time-of-use rates on ownership costs.

Key findings are as follows:

  •  EVs on average cost more than their internal combustion engine (ICE) or hybrid electric vehicle (HEV) counterparts, though this gap is substantially reduced with the federal tax credit.
  •  The Nissan Leaf is cost competitive without the federal tax credit and has the lowest lifecycle vehicle cost when incorporating the federal tax credit (among all vehicles considered).
  •  Electricity rates in Hawaii are much higher than the national average. Using the Energy Information Administration’s range of forecasts for future oil prices (low, reference and high), a set of future electricity and gasoline prices are determined. The model finds that when oil prices are low or reference, lifetime fuel costs are higher for EVs than other vehicles. When oil prices are high, on the other hand, EVs offer notable cost savings while accounting for Hawaii’s historic relationship between oil prices and electric rates.
  •  Having residential PV substantially brings down the cost of EV ownership, even considering the capital expenditure for PV panels.
  •  The pilot and proposed TOU rates offered by the utility reduce lifecycle EV fuel costs, assuming charging only when rates are lowest, by an average of 10%.

Where do Social Preferences Come From?

Where do preferences for fairness come from? We use a unique field setting to test for a spillover of sharing norms from the workplace to a laboratory experiment. Fishermen working in teams receive random income shocks (catching fish) that they must regularly divide among themselves. We demonstrate a clear correlation between sharing norms in the field and sharing norms in the lab. Furthermore, the spillover effect is stronger for fishermen who have been exposed to a sharing norm for longer, suggesting that our findings are not driven by selection effects. Our results are consistent with the hypothesis that work environments shape social preferences.
