By policy design, consumers are supposed to save money when they invest in solar energy. This paper presents a case study of what happens when a church goes solar and the finances go wrong. Following the installation of solar-photovoltaic panels, the Arizona church—in the Valley of the Sun, among the sunniest places in the country—decreased its energy consumption, but its electric bills went up. Through oral-history interviews of key stakeholders, the author investigates what happened, and what could be done to prevent other religious institutions and nonprofits from experiencing the church’s fate.

The increase in world seaborne trade over the past decade due to global economic and population expansion has resulted in a corresponding increase of world shipping fleet with even greater size and power requirements. The bulk of these ships use cheap and widely available fossil fuels, mainly oil for operation but which has deleterious effects on the environment. In order to address environmental concerns in the shipping sector, the International Maritime Organization (IMO), responding to the global call to reduce greenhouse gases emissions from international shipping adopted technical and operational measures. These are to ensure efficient energy management on ships and have led to the application of many innovative technologies including the use of renewable energies and alternative fuels on ships to minimize fossil fuel consumption and reduce emissions. However, in order to achieve a substantial emissions reduction in international shipping, the potential applicability of a technology which utilizes a universal renewable energy resource on the largest ship type in international shipping fleet should be investigated. This research focuses on investigating the potential of Solar Photovoltaic technology on dry bulk carriers using a developed methodology and Levelised cost of energy concept as the basis for comparison. The results of this research can be used to guide decision makers about the potentials of Solar Photovoltaic technology on dry bulk carriers in general whilst its developed methodology may be useful in the specific context for determining which ships and under what circumstances solar PV is an option.

Abstract This work shows the techno-economic comparison of the design of two solar photovoltaic systems: 1) on-grid (G-SPVS) and 2) off-grid (SPVS). Both schemes aim to supply electricity to a model water desalination plant located in Floreana Island, Ecuador. The annual load profiles and other operational details of the case study were previously obtained. For this research, a period of 15-years was analyzed. During this time, the maximum power of water pump system remained constant and represented the highest percentage of the electrical load, which changed each year influenced by the drinking water requirements of the population. Results from the HOMER PRO simulations showed that the SPVS produced higher surpluses of electricity. In contrast, the G-SPVS exhibited lower net present cost (NPC) and cost of energy (COE).
