Injustice Within Renewable Energy Life Cycles: Can Irena Offer A Solution?, G. Webster Ross
Injustice Within Renewable Energy Life Cycles: Can Irena Offer A Solution?, G. Webster Ross
IdeaFest: Interdisciplinary Journal of Creative Works and Research from Cal Poly Humboldt
This paper explores case studies of green colonialism, supply chain injustices, and poor e-waste management within renewable energy life cycles, and investigates how the International Renewable Energy Agency (IRENA) may be the best suited organization to address and mitigate these issues on a global scale. While renewable energy technology is often heralded as the key to a sustainable future, the life cycle of these technologies is riddled with human rights violations and other injustices. To begin with, many of the minerals required for assembling the hardware are mined in unregulated environments, resulting in several injustices such as health and safety …

Pressure retarded osmosis (PRO) is an emerging osmotic power technology that could mitigate the major challenges faced by seawater reverse osmosis desalination (RO): brine disposal and high energy consumption. The primary focus of this paper is process optimization for a linked seawater reverse osmosis (RO) and pressure retarded osmosis (PRO) water purification system. PRO generates power by using osmosis to “pump” water through a membrane from low pressure and low concentration to high pressure and high concentration (RO brine). This commercial-scale pilot effort explores process optimization for pressure retarded osmosis as an industrial process rather than theoretical or experimental process. …

Electrification Of Domestic Hot Water To Aid The Integration Of Renewable Energy In The California Grid, Alejandro Cervantes
Cal Poly Humboldt theses and projects
Water heating in residential buildings, also known as domestic hot water (DHW), is the third largest use of energy after appliances and space conditioning. About 90% of the residential buildings in the state use natural gas fueled water heaters, 6% use electricity, and a small percent use liquefied petroleum gas (LPG) or solar water heaters. The current energy use associated with residential water heating is small relative to the total amount of energy consumption in the residential building sector, but it is still a contributor of greenhouse gas (GHG) emissions. Improving hot water systems can be beneficial for bill customer …
