The Economics Of Battery Storage For Residential Solar Customers In Southern California, John B. Broughton, Prashanth U. Nyer, Candace E. Ybarra
Business Faculty Articles and Research
Battery storage coupled with solar panels became a consideration after the original net metering program in California (NEM 1.0) ended and gave way to the current net metering program (NEM 2.0). Under NEM 2.0, battery storage gives customers under time-of-use (TOU) rate plans the ability to store the excess electrical energy generated by their panels during sunlight hours (when electricity usage and resale rates are low) and then use that energy in the evening when rates are significantly higher. This reduces the amount of expensive electricity that the customer would have to purchase from the grid. It is widely expected …

Flow Characterization In Mine Ventilation Fan Blade Design Using Cfd, Anwar Endris Hassen
Journal of Sustainable Mining
In axial ventilation fans, the generation of a uniform flow velocity is desirable for better efficiency. To that end, different fan blade types have been developed to achieve better flow uniformity. This article aimed to characterize the flow distribution and its uniformity in four blade designs, namely constant chord, tapered blade, skewed blade, and tapered skewed blade, using Computational Fluid Dynamics (CFD). The study employs an iterative study where key study decisions are made as the study progresses. The study began with the selection of a blade profile for the study. A comparative study between the NACA seven-digit and four-digit …

Current State Of Seagrasses In Zanzibar: Impacts Of Coastal Economic Activities And Marine Protected Areas On Seagrass Cover, Danielle Purvis, Narriman Jiddawi
Capstone Collection
Seagrass meadows are located abundantly in Zanzibar, Tanzania and provide essential ecosystem services, such as sediment nutrient enrichment and blue carbon sequestration. However, seagrasses have been less researched or protected than other marine ecosystems. Although environmental variables affect seagrass health, evidence suggests that anthropogenic impacts are their greatest threats. The rapid expansion of seaweed farming and tourism and widespread use of harmful small-scale fishing practices in Zanzibar have contributed to the degradation and removal of seagrass meadows, disrupted coastal marine food chains, and reduced local biodiversity that seagrasses support. Public or private marine protected areas (MPAs) protect most of Zanzibar’s …

Scholarly Horizons: University of Minnesota, Morris Undergraduate Journal
The University of Minnesota Morris is well known for its commitment to sustainability. As a part of this commitment, the UMN Morris Office of Sustainability tracks and analyzes campus energy production, consumption and efficiency and summarizes this information as a carbon footprint. A carbon footprint combines all available greenhouse gas emissions data attributed to the institution from three categories: direct emissions from institution-owned or operated processes (Scope 1), indirect emissions related to the purchase of utilities (Scope 2), and indirect emissions from sources not owned by the institution but associated with its function (Scope 3). This project was an effort …

Population Structure Analysis Of The Endangered Oak Quercus Brandegeei, Carolyn Brinckwirth
DePaul Discoveries
As humans continue to impact landscapes and ecosystems throughout the entire world, many plant and animal species have faced major changes in their environments. The rare endemic oak, Quercus brandegeei, is one such endangered species located in the Sierra La Laguna mountains of Baja California Sur, Mexico. This tree occurs solely on the ephemeral riverbeds of the mountains, which are inundated seasonally by hurricane waters. It is important to understand the fundamental characteristics, like spatial distribution, of Q. brandegeei in order to develop restorative management practices to protect this tree against extinction. Determining the geographic distribution of a species …

Journal of Bioresource Management
Recently most farmers in developing country like Nigeria has resulted to the use of solid wastes as compost to replenish the deteriorated soils while some are farming on the abandoned waste dumpsite due to their richness in organic matter. This study assessed the soil nutrient and fertility status by investigating the influence of wastes (if any) on physical and chemical properties of soils in and around Lapite dumpsite for environmental sustainability. Ten soil samples each collected from three locations: dumpsite, downslope and upslope sites at depth of 0-20cm were analyzed for soil texture, bulk density, porosity, electrical conductivity, pH, organic …
