Implementing Changes

External Factors

Over the years, energy has become a serious interest to mitigate fossil fuels and create an overall better environment to live in. Companies taking action have developed teams known as R&D (Research and Development) to develop, improve, and control new systems for energy. Whenever technology is used or developed, efficiency (limiting energy waste while maintaining flow) and conservation of energy (energy rate is balanced through the system) are the two main performance measures that are discussed. Besides efficiency and energy conservation, other factors like environment, proper use, reliability, security, and growth for innovation need to be addressed.

"For example, research on lighting patents between 1992 and 2007 suggests that governance processes, which strengthen energy performance standards and constant R&D investments, could spur energy innovation; specifically, energy and environmental policies – and the patenting process in particular – significantly impacted technological innovation (Kim and Brown, 2019)." [1] R&D has a positive affirmation towards significant success in innovations. Patents are a subset of R&D teams that prove an inventor's idea works in practice and serve as a gateway for revolutionary changes. Even though lights have been around since the early 1800s with Thomas Edison's first commercially patented light in 1879, there will be continuous improvements in light sources and better cables for emitting light. Countries need to be able to spend more on R&D as the economic growth from these ideas equates to increasing market gain and a long term effect on support for these energy technologies on the environment.

Along with a country's advancement to innovation, the knowledge and experiences of the workers need to be at a high level. "In the long-term, or up to the year 2050, it was found that the possession of priority areas for smart specialisation and educational programs collectively had the most significant influence on the nation’s research and innovation system." [1] The greatest and most powerful organ is the brain. When you relay knowledge and understandings to others, not only do you spread information which means that more people will have different views. This also allows for younger generations to keep developing new technology and building upon older understandings. This is an important feature when coming up with the best technology because without useful skills with how devices work, we can never improve.

"The growing use of wind and photovoltaic energy production has an inherent uncertainty associated with their intermittency. These RE sources depend on seasonal, daily, and hourly weather conditions to generate electricity, such as wind speed and direction, and solar radiation." [2] Even renewable resources are not the be all end all solution. Any application within a system has flaws. Solar power needs to be able to have minimal clouds in the sky throughout the day and maximize the amount of radiation trapped in each solar cell. On the other hand, wind turbines need wind. Wind is created by the uneven pressure areas on Earth based on heating and cooling. If this doesn't happen and with a high enough intensity, the wind turbines will not create energy. These systems are dependent on external conditions that we cannot control which cuts into reliability.

Energy security is the storage capacity of energy but also the consistent acquisition of energy. Materials like lithium-ion for batteries and even are dwindling. While hydrostorage technology usually comes with a lapse timeframe from when it is operating to being stationary. Engineers will face a tough task of meeting future demand for energy storage, and will have to come up with new solutions to resolve this. Another problem we face as a nation is becoming too reliant on imports or being content with traditional ways. "Hungary and Slovakia are reliant on gas for over half of the energy requirements of the buildings stock (including residential, commercial and public buildings) and are therefore in a vulnerable position with regard to gas supply." [3] Energy security does not only rely on supply from the actual equipment acruing the energy, but it is consistent with relationships between other countries. Companies need backup plans for when equipment and supply is low. Expanding alternative routes will make countries less vulnerable powering homes and facilities. Options may include bonding with nearby nations, progressing the nations own technology to be self-reliant, or using natural resources that the lands provide. These two countries also have a colder climate so certain technologies will be easier to implement like gas lines which wouldn't freeze. For instance, if you use wind turbines during the winter, the ice would prevent the turbines from being able to turn efficiently. This would cause greater loads on the blades and may even damage the turbine. This is another factor to consider when considering an overall better technology.

Education at UIUC [4]

Seminars and Workshops

ENG 471: Seminar Energy & Sustainable Engineering - Students will be able to listen to guest lecturers that are experienced with global challenges such as energy demand, climate change, energy security, how energy impacts the economy, energy policies, and renewable energy deployment. You will be able to predict and quantify if the infrastructure can be used and set up correctly. All of these external factors play a vital role for engineers to think about when applying procedures and reaching an end result.

Institute for Sustainability, Energy, and Environment Sustainability Month - Student for Environmental Concern Talks about ongoing concerns with the environment and how systems are not always perfect. Through the Sustainability Summit, students will get to have a Q&A session with 6 experts a part of SECS and talk about what fieldwork entails. Another event revolving around a discussion for the Climate and Equitable Jobs Act, which is a law set by Pritzker to get clean energy by 2050. [5]


Classes

CEE 434: Environmental Systems I - Introducing concepts, designs, and planning of environmental systems. Students would be able to learn how energy-applied devices will impact the environment with this class. Taking into account the need for renewable energy and clean applications, students have the opportunity to gain knowledge on how to implement solutions towards broader goals.

TSM 438: Renewable Energy Applications - Students are able to look at all angles of renewable resources: geothermal, solar, wind, and biomass. Using class knowledge about energy and energy conservation/conversions, you will be able to figure out how to find alternative systems. This can include ensuring reliable systems for commercial use, new technology for buildings, and eliminating risk with systems.


Projects:

ENVS 492: Sustainability, Energy, and Environment Capstone - Taking this capstone class students are able to take on projects to help serve their community, use campus tools, and collaborate with organizations to assist in solving the students' mission. An example of a project in the past was "Greenhouse Gas Analysis of the Champaign County Forest Preserve District". These students were able to conclude that the Museum of the Grand Prairie had the largest amount of emissions given off and its energy ability creates higher consumption to operate. After collecting evidence, "The Museum’s furnaces were last upgraded in 2010 and 2013 and are due for replacement within the next 5-8 years." [6] The museum was running on natural gas furnaces which takes a gas line, igniting this fuel via a burner, and blowing the air into ducts. This process has a higher amount of energy and CO2 waste as well as older models usually running at one speed, making the energy consumption running at maximum all the time.

iCAP (Illinois Climate Action Plan)

At iCAP, professors and researchers are admitted to a council overseeing a bunch of topics like energy on the UIUC campus. As a campus of over 40,000 students, this is a great task. UIUC is set up as a city in itself with underlying problems related to emissions, cooling/heating within buildings, and pilot methods for cleaner energy. With iCAP, students have the chance to learn from the iWP (iCAP Working Group) through events and meetings. Q&A sessions are set up as well as virtual meetings to ensure the iWP is working effectively and using resources to solve problems. Students can take advantage of this by learning about important advances and communicating with higher education advocates. For example, the Illinois Climate Action Plan iCAP 2020 states, "Increasing space utilization rates can include clarifying appropriate allocation policies for various room categories and implementing innovative solutions like hot-desking (wherein workspaces are used by multiple people on a rotating basis)." [7] Slightlines, LLC was able to conduct experimentation as shown in Figure 5 that lead to UIUC being among the lowest in efficiency towards space utilization between other BIG10 universities. While people may not know this, space is a concern when you are operating unnecessary facilities and your occupancy per user versus Gross Square Feet is low. For UIUC to perform at close to net zero space consumption then the increased efforts toward using up space more effectively and altering outdated methods needs to be a priority towards energy goals.

Municipal and Local News

Keeping up with your city's Town Hall meetings and reading about local news can help you gain a different perspective on energy. Recently, Urbana has launched its own Solar project that will be finished by 2022 and take up 1300 acres of land. [8] The Solar project will generate 150MW, however, a downside to this much land ownership is the harm to wildlife and habitat destruction. Sciencing inputs based on the Ivanpah Solar System, "The same solar farm also came under scrutiny when an increasing number of bird deaths were reported on its premises. Many of their wings had been melted or burned off by heat from the solar farm’s mirrors." [9] While the sun does get hotter and beam more closer towards the South, the mirrors of solar panels can be a death sentence for some animals. Even solar panels have a negative impact by taking up too much water for cooling or storage purposes and this can take away from the water in the surrounding environment.
