Spectators have always been an integral part of the sports world, bringing unmatched energy and enthusiasm to stadiums. In parallel, stadiums themselves are now transforming into environmentally-conscious powerhouses, embodying sustainability through innovative energy solutions.

Short Summary:

  • Stadiums are integrating solar, wind, and other renewable energy technologies.
  • Government incentives and public funding support sustainable stadium designs.
  • Sustainable initiatives extend beyond energy savings to waste management and community engagement.

Sports stadiums have traditionally been a symbol of human energy and community spirit. Now, they are also becoming symbols of environmental responsibility through groundbreaking sustainability efforts. Integrating renewable energy sources such as solar panels and wind turbines, stadiums worldwide are redefining their role in communities and reducing their carbon footprints significantly.

For example, the Philadelphia Eagles’ Lincoln Financial Field has become an industry leader in sustainability. The stadium installed 11,000 solar panels through a partnership with NRG, a retail electricity supplier. These solar panels not only power the stadium but also contribute to the local energy grid, showcasing how sports facilities can be power-positive. This initiative is expected to save the Eagles more than $60 million in energy costs over the next two decades.

“We have a responsibility to our fans, players, community, and planet to tackle sustainability head-on and set a new standard for sustainability in sports,” said Sandra Douglass Morgan, President of the Las Vegas Raiders.

The Indianapolis Motor Speedway, home to the iconic Indy 500, also took substantial steps towards sustainability. The Speedway leased land adjacent to the track to build the world’s largest solar farm for a sports facility. The nine-megawatt solar power plant, constructed with 39,312 solar panels, supplies energy under a long-term agreement to the Indianapolis Power & Light Company, further supporting renewable energy infrastructure.

Similarly, the Minnesota Vikings have ensured that their US Bank Stadium is powered entirely by renewable energy, covering 100% of its electricity needs with wind energy credits. In addition to this, the stadium employs a transparent plastic polymer roof that maximises natural daylight, helping reduce the reliance on artificial lighting and HVAC systems. The Vikings’ efforts in these areas have led to annual savings of $1.26 million in energy costs.

The Miami Heat has also demonstrated a commitment to sustainable practices by installing a 24,000-square-foot solar canopy at its American Airlines Arena. This impressive structure reduces the arena’s energy costs by $1.6 million per year. It also adds to the visual appeal with a colour-changing LED lighting system, enhancing the fan experience while promoting sustainability.

Government Incentives Fuel Sustainability

Government incentives play a critical role in encouraging the integration of renewable energy technologies in sports facilities. The US tax code’s section 179D offers tax deductions for building owners who implement energy-efficient systems in large commercial buildings like stadiums. This can include solar panels, wind turbines, and geothermal systems. The Inflation Reduction Act has further enhanced these incentives, increasing the tax deduction to potentially $5 per square foot from the previous $1.80.

Many stadiums also benefit from significant public funding. For instance, the state of Tennessee and Nashville agreed to provide $1.26 billion to build a new stadium for the Tennessee Titans, with designs that qualify for LEED certification. LEED, a voluntary programme by the US Green Building Council, assesses various environmental impacts and rewards facilities based on their specific achievements. In the US, 32 stadiums in professional leagues have been recognised with LEED certification, underlining the shift towards greener sports venues.

Environmental Impact and Innovation

Sports stadiums’ environmental impact can be considerable, given their high energy consumption and carbon emissions. However, renewable energy installations across various facilities are making substantial strides in reducing this footprint. Arena, home to the LA Lakers, Clippers, and Kings, has installed 1,727 solar panels, significantly reducing CO2 emissions. Building on this, the stadium also employs a bank of fuel cells to generate electricity onsite, mitigating additional tonnes of CO2 emissions.

The soon-to-open Inuit Dome for the LA Clippers aims to be the first climate-positive stadium globally, powered entirely by onsite solar energy and battery storage, underscoring the potential for innovative green technologies in sports facilities.

Other examples include the Baltimore Ravens’ M&T Bank Stadium, which features 1,210 solar panels, and the New England Patriots’ stadium, which utilises 3,000 solar panels to meet 60% of its energy requirements. Reducing carbon emissions by thousands of metric tonnes collectively, these examples highlight the essential role of renewable energy in modern sports facilities.

“Surprisingly, sports venues are pioneers in the promotion of sustainability. Many sports venues have jumped on the sustainability bandwagon in a race to minimise their carbon footprint, preserve their green legacy, and take the lead in innovation,” notes Climate Action, a UK-based organisation.

Legal Maneuvering for Renewable Energy

Navigating state laws and regulations can afford sports organisations the leverage to access renewable energy at competitive rates. An exemplary case is Allegiant Stadium, home of the Las Vegas Raiders. By leveraging Nevada’s legislation, the Raiders secured a long-term, lower-cost electricity contract through NV Energy. This contractual agreement, supported by the addition of three new solar projects, allows Allegiant Stadium to be 100% powered by renewable energy.

Allegiant Stadium’s accomplishments in sustainability didn’t stop with energy. The venue has also achieved LEED Gold Certification and implemented extensive waste diversion practices. Initiatives like converting 12,000 pounds of kitchen waste into energy and composting 160,800 pounds of grass clippings highlight the stadium’s comprehensive approach to ecological stewardship.

Setting Examples and Encouraging Content

Allegiant Stadium is an illustration of how sports can inspire broader societal changes regarding sustainability. Its transformation into an entirely renewable energy-powered facility ahead of the 2024 Super Bowl highlighted how high-profile venues can lead environmental efforts at a larger scale.

“Large stadiums experience extremes in energy usage. They must be optimised to handle both peak capacity events and everyday operations efficiently,” explains Erik Thomas, design phase executive with Mortenson.

Stadiums like Golden 1 Center in Sacramento, which is 100% solar-powered and known for its iconic purple laser beam celebration, can serve as educational tools for the public, provoking discussions and awareness about renewable energy investments.

Sports organisations are not only mitigating their environmental impact but also finding practical ways to engage their fan base in these efforts. For example, the Atlanta Braves’ “Green Team” initiative encourages fans to recycle at the stadium, reinforcing community participation and eco-friendly practices. On the operational front, energy-efficient investments like those at Levi’s Stadium, featuring a 27,000-square-foot green roof, demonstrate sports’ potential to pioneer sustainable building practices.

The Way Forward: Fans and Infrastructure

Supporting the environment is becoming just as important to sports teams as their performance on the field, impacting decisions taken by both teams and their fans. For instance, Bionic, a British energy consultancy, has devised indices to measure stadiums’ energy efficiency to compare their sustainability scores. Arsenal’s Emirates Stadium, with its advanced battery storage and LED lighting systems, tops these rankings, proving that operational sustainability can coexist with high-level sports performance.

The overarching benefits of investing in sustainable sports infrastructure are clear. Not only are there significant cost savings and improved fan engagement, but brand reputations are enhanced too. Corporate sponsorships and naming rights become more attractive, highlighting the value of eco-friendly stadiums.

“A stadium in Minnesota might focus on efficient lighting and ventilation systems to mitigate the impact of cold Midwest winters on fans, whereas a facility in Florida might aim to harness solar panels while maintaining hurricane resiliency,” says Julianne Laue, director of building performance at Mortenson.

Ultimately, embracing green initiatives is a strategic imperative, pushing sports organisations to align with broader societal values. As more stadiums adopt renewable energy systems and implement comprehensive conservation measures, the sports world sets a powerful example for how industries can turn sustainability into a reality, delivering an electrifying experience for the planet and fans alike.
