Invest in energy-efficient lighting
Investing in energy-efficient lighting is one of the simplest and most effective ways to save energy on a college campus. Transitioning from incandescent to LED lighting can significantly reduce electricity costs. LED bulbs use approximately 75% less energy than incandescent bulbs and have a longer lifespan, resulting in reduced replacement costs over time. While the initial investment in LED technology may be substantial, the long-term savings can be significant.
To further enhance the benefits of energy-efficient lighting, colleges can implement energy management systems. These systems automatically turn off lights when they are not in use, optimizing energy usage and reducing waste. Additionally, colleges can explore the use of occupancy sensors in classrooms and buildings. These sensors ensure that lights are only turned on when someone is present, further reducing unnecessary energy consumption.
Colleges can also consider replacing traditional light fixtures with more sustainable alternatives. For example, the University of Maryland replaced light fixtures with energy-efficient options, contributing to their overall energy-saving efforts. This simple adjustment can lead to substantial savings over time, as it reduces both energy consumption and associated costs.
Another innovative approach is the installation of photovoltaic panels, which can generate a significant amount of electricity for the campus. The University of Maryland's student center, for instance, utilizes 84 photovoltaic panels to produce around 23,973 kWh of electricity annually. This not only reduces the campus's reliance on traditional energy sources but also demonstrates a commitment to environmental sustainability.
By investing in energy-efficient lighting and exploring complementary initiatives, colleges can effectively manage their electricity costs. These measures not only reduce financial burdens but also contribute to a more sustainable future, benefiting both the institution and the wider community.

Install solar panels
Solar energy is a viable option for colleges and universities to manage their electricity costs. Photovoltaic (PV) solar panels are an increasingly popular and renewable energy source, representing approximately 46% of new US electric generation capacity in 2022. Colleges can take advantage of federal incentives, such as those in the Inflation Reduction Act, to drive up solar usage and reduce costs.
Solar panels are a safe investment, generating free energy and offsetting initial costs. The larger the solar system, the lower the cost per watt, and colleges have an abundance of roof space to accommodate this. Flat roofs, common in educational buildings, make for an easy installation process. The potential for lower operating costs is a big draw, and solar energy can help offset large electric bills.
Colleges can also benefit from the durability of solar panels, which are designed to last 25-30 years and require minimal maintenance. They can withstand all kinds of weather conditions and provide backup power in emergencies, such as power outages.
Solar installations offer a level of energy independence and can be a powerful indicator of a college's commitment to sustainability and environmental practices. This can create a positive image for the college, attracting eco-conscious students and investors.
For large institutions, installing off-site solar arrays can meet a significant portion of their electricity needs. However, for small to medium-sized colleges, onsite installation on the roof or surrounding grounds will likely be the best option.

Use energy management systems
One of the most effective ways to manage electricity costs in colleges is to use energy management systems. These systems monitor and control energy use in a building or across an entire campus. They can be used to automatically turn off lights and electronics when they are not needed, leading to significant energy savings. For example, Miami University was able to reduce its annual campus utility bills for electricity and natural gas from $12 million to $5 million, despite a 25% growth in campus square footage over the same period.
Energy management systems can also provide valuable data and online monitoring that can be used to further improve energy efficiency. This data can be used to identify areas where energy is being wasted and implement targeted solutions. For instance, the University of California, Irvine has an award-winning energy management program that has been recognized by the US.
Colleges can also invest in energy efficiency upgrades for their buildings. This may include transitioning from incandescent to LED lighting, which uses 75% less energy and has greater longevity. While there can be substantial upfront costs associated with this transition, the long-term savings are significant. Additionally, colleges can install solar panels or purchase energy from renewable sources, such as wind power, to reduce their electricity costs and lessen their environmental impact.
Partnering with an energy service company (ESCO) can help colleges identify areas for energy and infrastructure improvement. An ESCO will perform a feasibility study to determine the best course of action and define an implementation roadmap. This can help colleges maximize their infrastructure and improve energy efficiency without taking focus away from their students. By addressing aging infrastructure and deferred maintenance, colleges can reduce energy consumption and costs, freeing up operational budgets for student-oriented programs.

Improve infrastructure
Improving infrastructure is key to reducing electricity costs in colleges. Colleges and universities need to upgrade their infrastructure to reduce energy costs, increase efficiency, minimize waste, and reduce carbon emissions.
One way to improve infrastructure is to transition from incandescent to LED lighting. LED bulbs use about 75% less energy than incandescent bulbs and last longer. While there may be substantial upfront costs to making this transition, the long-term savings are significant.
Colleges can also invest in solar panels to generate electricity. For example, the University of Maryland installed more than 2,600 solar panels, which provide 5.25 kW of energy. The university also purchases 66 million kWh of energy from clean wind power annually, offsetting 60% of its electricity use.
Another way to improve infrastructure is to implement energy management systems that monitor and control energy use. These systems can automatically turn off lights and electronics when they are not needed, leading to significant energy savings. For example, Miami University reduced its annual campus utility bills for electricity and natural gas from $12 million to $5 million over a 10-year period, despite a 25% growth in campus square footage.
Colleges can also work with energy service companies (ESCOs) to identify areas for improvement and determine the best technologies to implement. For instance, Stanford University opened a Central Energy Facility that makes the heating cogeneration process 70% more efficient and launched a campus heat recovery system to efficiently heat and cool buildings while reducing energy waste.
Additionally, colleges can invest in new technologies and energy sources to improve their infrastructure. For instance, they can buy virtual power purchase agreements for wind and solar power to achieve 100% renewable energy. They can also take advantage of low-cost, newer technologies as they become available.

Buy virtual power purchase agreements
Colleges and universities can take several steps to manage their electricity costs. One option is to transition to more efficient lighting systems, such as LED bulbs, which consume significantly less energy. Another strategy is to implement an energy management system that automatically turns off lights and electronics when not in use, providing both energy savings and valuable data for further efficiency improvements.
Beyond these on-site interventions, institutions can also explore off-site solutions, such as purchasing virtual power purchase agreements (VPPAs). A VPPA is a long-term financial contract between a large-scale energy buyer, such as a college, and a developer of renewable energy projects, like wind or solar farms. This agreement allows the buyer to purchase renewable energy at a pre-agreed fixed price, acting as a hedge against future energy price fluctuations.
In a VPPA, the buyer does not physically receive the energy produced; instead, they continue paying their utility bills as usual. The VPPA is a purely financial transaction where, if the market rate for energy is higher than the agreed-upon fixed rate, the buyer pays the difference to the developer, and vice versa. This structure ensures the buyer's exposure to volatile energy prices is limited.
Additionally, the buyer receives Renewable Energy Credits (RECs) as part of the VPPA, enabling them to make claims about their greenhouse gas reductions and renewable energy purchases. These credits can be traded, and if wholesale prices rise, the profits from trading RECs can offset higher conventional energy costs.
VPPAs offer colleges a way to quickly and meaningfully advance their sustainability and climate goals. However, it is essential to carefully consider the intricacies of these agreements to ensure they align with the institution's unique needs and objectives.
