What percentage of the 126 teams in major leagues used renewable energy in 2013?

In 2013, it was reported that a notable percentage of major league teams began to incorporate renewable energy into their operations, reflecting a growing trend towards sustainability within the sports industry. The correct choice indicates that less than 40% of the 126 teams utilized renewable energy at that time. This percentage signifies an emerging awareness and commitment to reducing the environmental impact of sports facilities, which often include large energy consumption due to events and operations.

The statistic presented also highlights a crucial point about the ongoing evolution of sports facility management towards more sustainable practices. A figure below 40% suggests that while some teams were leading the charge in adopting renewable energy, there was still significant room for growth and further adoption across the league.

In contrast, the other options suggest higher levels of adoption that were not substantiated by the data from that time. The movement towards integrating renewable resources in major league sports has been on the rise since then, underscoring the wider industry trend towards sustainability and environmental responsibility.
