SPEAR is an organization committed to promoting the most environmentally sustainable path for Vanderbilt. Currently, our university produces about 20% of its power and much of its heat from an on-campus coal and natural gas plant. In the short-term, SPEAR supports this source of electricity for our school. There are three central reasons for this choice.
Firstly, the alternative source of electrical power in Nashville is the Tennessee Valley Authority (TVA). This source also burns coal and at a higher rate than the Vanderbilt plant. As such, advocating against on-campus coal usage cannot be productive.
Furthermore, the Vanderbilt plant is a co-generation plant. Not only does it also use natural gas and solar power, but it does so very efficiently. To ask for power from sites off our campus would increase the amount of coal being burned for the same amount of electrical power. The electricity would have to travel further, have to produce additional heat, and would lack the secondary benefits of on-campus production.
Finally, there are currently no viable alternatives to coal for Vanderbilt. Natural gas is unreliable in this part of the United States, and it has a highly variant cost. While in the long-term, we expect Vanderbilt to switch to 100% green power, those options are currently either too costly, bulky, or inconsistent.
There is no question that coal is a terrible resource for us to use, and SPEAR fully expects and encourages the Vanderbilt administration to eventually replace the coal portion of the co-generation plant with a more eco-friendly option. All of this, however, is a goal for the future. In the meantime, our co-generation plant it the most efficient way to provide back-up power to Vanderbilt and out Medical Center. SPEAR feels it is more important to focus on sustainability initiatives on campus and push for greener energy from TVA. TVA offers the option to buy less coal powered electricity, which Vanderbilt could purchase. Right now that electricity is extremely expensive, but in the future it may be something to consider.
