Over the last few weeks, I have toured sites that hold an exciting potential for the next chapter in America’s energy future. Most people don’t look at landfills, contaminated industrial sites, or parking lots with a twinkle in their eyes, but I do. I hope you will too.
As a solar person, I am always on the look-out for prime sites for solar photovoltaic (PV) systems. In addition to solar resources, I look for a few simple things: clear southern exposures, flat or gentle grades, and close proximity to power lines. In general, I am looking for space, whether it is an open rooftop or an abandoned rail yard.
With over 13,000 sites and nearly 22 million acres of EPA-tracked potentially contaminated and underutilized properties nationwide, I see an untapped potential for large-scale deployment of renewable energy. That acreage receives a whole lot of sunshine and, in some cases, gets its fair share of wind. For communities interested in renewables, these sites offer a unique value proposition.
In many cases, these properties have blighted the community for years. From the perspective of a renewable energy developer, these sites are attractive due to their proximity to existing distribution or transmission lines, favorable zoning, and potentially lower land costs. With this redevelopment approach, I see the potential to turn these liabilities into community assets by remediating the site and deploying pollution-free energy facilities.
Partnering with DOE’s National Renewable Energy Laboratory (NREL) and remediation experts here at EPA, the RE-Powering team converted our collective knowledge into new tools to guide state and local governments, site owners, clean-up project managers, and other stakeholders through a process for screening potentially contaminated sites and landfills for their suitability for future redevelopment with PV or wind energy.
This knowledge is now bundled in a simple decision-tree format to enable communities to screen sites without needing renewable energy expertise. We built the screening tools to provide quick feedback on whether or not a site could be viable based on technical or economic criteria. The tools provide a thorough check than my quick check during a site walk. Throughout the process, we provide context for each of the criteria and point to additional tools and references to work through the evaluation process. Our goal is to empower communities to bring their vision of a solar array or wind farm one step closer.
While site walks at brownfields and landfills don’t always offer inspiring views, they are the next step in an inspired approach to expanding our American-made, renewable energy generation. Screen your sites. Take a walk. RE-Power America’s Land.
