Efficiency

Activities

The previous two activities in this module have shown us the importance of conservation laws. These laws provide extra “tools” that allow us to analyze certain aspects of physical systems and to be able to predict the motion of objects in the systems without using more complicated analysis. Even in situations wherein we cannot exactly solve the motion, these laws are incredibly useful. For instance, if someone shows us an incredibly complicated device that can seemingly produce electricity with no energy input whatsoever, we know not to invest money in this device, as it must be a sham since it …

First Law Of Thermodynamics

Activities

In last week’s activity, we calculated the motion of objects by studying the forces on them. Using Newton’s Second Law of Motion, we were able to relate the forces on an object to the acceleration it experienced. The presence of constant forces led to constant accelerations, which corresponded to linearly-increasing velocities with respect to time. Comparisons made between the velocities we measured and those calculated from a study of the forces on the objects allowed us to validate Newton’s equation F = ma. In this week’s activity, we are going to investigate almost the same experimental setup as last week, …

Newton's Second Law

Activities

There are two ways to study the dynamics of a system in which there is motion. One of these is to study the kinematics of the system to see if there is any acceleration. If there is an acceleration, then this implies that there is a net force on some part of the system. If there is no acceleration, then this means that either there are no forces on the system, or that the forces within the system are all balanced. The other way to study the system is from an energy standpoint. Energy can flow from potential to kinetic, …

Home Energy Capstone

Activities

The other three weeks of the Home Energy Module study energy flow and usage in our homes. In the R-Factor activity, we observed that the material used in the construction of our homes has a tremendous impact on the rate at which heat flows through its exterior surfaces. In Home Audit and Home Analysis activities, we performed an energy audit of our homes to estimate the amount of money that it costs to power it. As you have seen during our studies, there are many factors that affect the cost of energy in our homes. The right choices of materials, …

Home Energy Audit

Activities

In the 1800's, scientists found, empirically, that rules exist that determine how energy can be transferred. The first of these rules is called the First Law of Thermodynamics. This law is usually stated as, "Energy can neither be created nor destroyed; it can only be transferred from one form to another." This often leads to the re-titling of this law as the Conservation of Energy Principle since it says that energy must be conserved. This statement of the First Law does not say anything about how energy can be transferred, though. It turns out that there are only two ways. …

The Global Energy Crisis, Katie Calhoun

Facing the Future Lessons

The world is at an energy tipping point. Countries and communities can choose to be proactive or wait and be reactive, however it is much less costly to do the former. In this project, high school environmental science students will examine the current energy use and concerns in a named country or community, analyze the pros and cons of the current energy situation and how it effects the social, economic and environmental aspects of the culture, then create a more sustainable, resilient plan for that country.

Electricity Demand Due To Policy Change In The U.K., Kevin W. Doherty

Journal of Environmental and Resource Economics at Colby

This paper examines United Kingdom Electricity Demand with regards to the Climate Change Act, which was enacted in November of 2008. Through actual demand data obtained from Nationalgrid, a U.K. based gas and electric utility company, this paper seeks to find out if the Climate Change Act has started to achieve its goal of reducing carbon emissions by looking at trends of electricity demand. Burning fossil fuels to produce electricity is a major contributor to global warming in the U.K. and policies enacted do not always live up to their ultimate goals. This paper tests how on track the Climate …

Feasibility Study: Tangier Island Wind Turbine Deployment, Patrick Landess

Senior Honors Projects, 2010-2019

The 2014 Virginia Energy Plan set the goal of 25% of the energy produced in the state to be derived from renewable resources by 2025. Wind energy is one of the most prominent renewable resources in the state, with a potential wind capacity of approximately 1800 MW. The Virginia Department of Mines Minerals and Energy (DMME) looks to incentivize both small-scale and commercial renewable energy projects. As a result of this policy initiative and the competitiveness of renewable energy, the Center for Wind Energy (CWE) at James Madison University established the Distributed Wind Assistance Program (DWAP).

This honors project serves …

Software Development For Home Energy Audits: Reducing Energy Consumption In Harrisonburg Through Technology, Brantley E. Gilbert

Senior Honors Projects, 2010-2019

Fossil fuels play a vital role in our daily lives. Oil, natural gas, and coal powers our cars, heats our homes and water, and are used by power companies to generate the massive amounts of electricity used every day by the United States. However, this reliance on a finite source of energy is not sustainable. Fossil fuels such as these are non-renewable resources whose production will eventually be unable to keep up with the rate of consumption. Furthermore, the extraction of the stored energy in these fuels through combustion releases harmful substances into the environment, including toxins and greenhouse gases …

Transitions In Climate And Energy Discourse Between Hurricanes Katrina And Sandy, Emily M. Cody, Jennie C. Stephens, James P. Bagrow, Peter Sheridan Dodds, Christopher M. Danforth

College of Engineering and Mathematical Sciences Faculty Publications

Although climate change and energy are intricately linked, their explicit connection is not always prominent in public discourse and the media. Disruptive extreme weather events, including hurricanes, focus public attention in new and different ways offering a unique window of opportunity to analyze how a focusing event influences public discourse. Media coverage of extreme weather events simultaneously shapes and reflects public discourse on climate issues. Here, we analyze climate and energy newspaper coverage of Hurricanes Katrina (2005) and Sandy (2012) using topic models, mathematical techniques used to discover abstract topics within a set of documents. Our results demonstrate that post-Katrina …

Energy-Extended Ces Aggregate Production: Current Aspects Of Their Specification And Econometric Estimation, Paul E. Brockway, Matthew K. Heun, João Santos, John R. Barrett

University Faculty Publications and Creative Works

Capital-labour-energy Constant Elasticity of Substitution (CES) production functions and their estimated parameters now form a key part of energy-economy models which inform energy and emissions policy. However, the collation and guidance as to the specification and estimation choices involved with such energy-extended CES functions is disparate. This risks poorly specified and estimated CES functions, with knock-on implications for downstream energy-economic models and climate policy. In response, as a first step, this paper assembles in one place the major considerations involved in the empirical estimation of these CES functions. Discussions of the choices and their implications lead to recommendations for CES …

The Water-Electricity Nexus In California: Drought-Induced Risk To Thermal Electricity Generation, Timothy S. Hyles

Cal Poly Humboldt theses and projects

Investigating the possibility that drought might limit the water supply needed for thermal electricity generation in California, power plant water consumption data was compared to urban and agricultural consumptive demands to identify areas where power plants might contribute to regional water stress. To identify areas where power plants might be impacted by water stress, regional power plant, urban, and agricultural water demands were also compared to the available water supply. A list of power plants that would contribute most to regional water scarcity (individually and in aggregate) was highlighted, based on the plant’s water consumption volume, water-intensity, and water source. …
