State of the nation: Customizing energy and finances for Geothermal Technology in the United States residential sector
Renewable and Sustainable Energy Reviews, 2021Co-Authors: Rebecca Neves, Heejin Cho, Jian ZhangAbstract:Abstract Geothermal residential heating and cooling systems have undeniable potential savings. The possibilities of the energy savings with a Geothermal heat pump system is well-established in the commercial and residential sectors. Building location has a critical impact on the performance of Geothermal heat pump systems and magnitude of savings. An important contribution of this paper takes the step past technological optimization to investigate 12 climate zones across the contiguous United States. Residential homes within common neighborhoods are thoroughly analyzed by considering soil characteristics and home construction features. Within these climate zones, federal and all local incentive programs are quantified to determine an accurate expectation for capital investment payback period, a critical factor for system attractability. Ultimately, a climate zone is classified as either a promising or poor candidate for residential Geothermal Technology based on data from previously conducted human interest polls regarding payback period on energy savings investments. With such lasting potential delivered to the hands of consumers, Geothermal energy use still experiences slow implementation. This paper conducts a study integrating data on Technology, finances, and human nature to identify the prevailing barrier to widespread Geothermal execution. Solid evidence on energy and monetary savings reveals the dominant barriers are initial capital investment and long payback period. This paper highlights the immense positive impact that local incentives have on affecting these two prevailing deterrents.

Pairing Geothermal Technology and solar photovoltaics for net-zero energy homes
Renewable and Sustainable Energy Reviews, 1Co-Authors: Rebecca Neves, Heejin Cho, Jian ZhangAbstract:Abstract Homeowners across the globe are continually seeking methods of improving energy efficiency for financial benefit and personal satisfaction. From small contributions such as swapping light bulbs to large capital investment initiatives like upgraded heating and cooling systems, homeowner decisions require accurate data and confidence in potential outcomes. This study models the path to net-zero energy for two separate heating, ventilation and air conditioning (HVAC) plus solar photovoltaic (PV) systems in residential buildings across 12 Unites States climate zones, and determines the optimal combination for each climate zone. An existing, traditional air-conditioning system with natural gas furnace is paired with a PV array. The net-zero results are compared to the same residence upgraded to a climate-customized Geothermal heat pump HVAC system paired with a PV array. Results confidently favor the Geothermal HVAC system + PV for climates with a significant heating demand in winter, and the baseline + PV system for cooling-dominant climates, exceeding $3,900 and $3,500 annual household savings, respectively. A major contribution is the introduction of a template that predicts the net-zero system option for climate zones outside the 12 studied. Patterns in local soil properties, sun intensity and financial incentives allow for net-zero system predictions nationwide. For example, all locations resulting in a baseline + PV net-zero system have strong sun intensity ratings. This research delivers climate-specific recommendations for the preferred net-zero HVAC + PV system through analysis of accurate energy performance and financial forecasting. Recommendations provide homeowners with valuable expectations on two HVAC + PV options along the path to a net-zero energy home.

Flexible Opportunities with Geothermal Technology: Barriers and Opportunities
Electricity Journal, 2015Co-Authors: Benjamin MatekAbstract:Geothermal power has typically provided baseload services, which will continue to be important in the future as coal and nuclear power plants retire. However, new developments that increase Geothermal power's flexibility will allow Geothermal power plants to integrate more effectively in electricity grids supplied by substantial amounts of variable power sources. One key barrier is that current contracts between electric utilities and Geothermal operators do not address ancillary services.

societal acceptance of an emerging energy Technology how is Geothermal energy portrayed in australian media
Renewable & Sustainable Energy Reviews, 2015Co-Authors: Lygia Romanach, Simone Carrcornish, Grace MuriukiAbstract:The media shapes and is shaped by public sentiment of emerging technologies. One way to gauge the societal acceptance levels of an emerging Technology, such as Geothermal energy Technology in Australia, is to analyse how the Technology is reported in the media. This study identified the benefits and risks that have been reported and the social actors represented, informed by extant research of factors that impact societal acceptance. A total of 451 Australian news items on Geothermal energy Technology published between July 1st, 2011 and June 30th, 2012 were used for this content analysis, which encompassed the release of the Australian Government's Clean Energy Plan. Consistent with Geothermal Technology being an emerging Technology in Australia, economic feasibility and uncertainty about the Technology were the most frequently reported risks. Industry was one of the most cited social actors in Geothermal news media and it was more likely to be cited in articles reporting the economic feasibility and uncertainty about the Technology, reflecting the current state of the industry in Australia. Renewable and low-emission energy were the most frequently cited benefits, which were often reported as part of the Australian Government Clean Energy Plan. Overall, this emerging Technology has maintained a restricted profile in the media to date, with limited controversy or politicisation. This profile is likely to remain, in particular the focus on the Technology economic feasibility, which remains the main challenge to the Technology entering large-scale development in Australia.

differences in public perceptions of Geothermal energy Technology in australia
Energies, 2014Co-Authors: Simone Carrcornish, Lygia RomanachAbstract:In Australia, Geothermal energy Technology is still considered an emerging Technology for energy generation. Like other emerging energy technologies, how the public perceive the Technology and under what conditions they are likely to accept or oppose the Technology, remains relatively unknown. In response, this exploratory research utilised online focus groups to identify: (1) the extent of agreement with Geothermal Technology before and after information, including media reports focusing on a range of the Technology’s attributes; and (2) how the characteristics of individuals with different levels of agreement vary. After information, within the sample of 101 participants, fewer reported being unsure, the minority disagreed and the majority agreed. Overall, the preference was for projects to be located away from communities. Participants that disagreed or were unsure, were more likely to report lower subjective knowledge of the Technology, lower perceived benefits and higher risks, and were less likely to believe people in their community would have the opportunity to participate in consultation. These characteristics suggest there are advances to be made by analyzing what contributes to different levels of acceptance. The findings also suggest that the location of projects will be an important consideration and that the conditions of acceptance are likely to vary amongst community members.
