It's April 1... and a big day if you love baseball... its OPENING DAY!

Following that theme... and taking on energy efficiency... here are the 5 most energy efficient major league ball parks according to The Alliance to Save

1. Marlins Park... Miami Marlins

  • The ballpark has an 8,000-ton retractable roof that requires a lot of energy to operate, but regenerative drive systems reduce power consumption so that it costs less than $10 in electricity to open or close.
  • Plumbing – which includes 250 waterless urinals – uses 52% less water than in similar stadiums. Meanwhile, landscaping around the stadium uses 60% less potable water for irrigation because its drought-resistant plants need less water.
  • Windows and glass panels provide ample natural lighting.
  • Marlins Park was built on the site of the old Orange Bowl, so it is accessible via multiple transportation options; the park also offers over 300 bike racks. In addition, 60% of the materials used to build Marlins Park came from within a 500-mile radius, which reduced fuel consumption.

2. Target Field... Minnesota Twins

  • Low-flow urinals, dual-flush toilets, and aerated faucets use 30% less potable water than conventional fixtures and save about 4 million gallons of water annually.
  • Rain recycle system allows the Twins staff to use rainwater to wash the seating area; per game, the system saves them 14,000 to 21,000 gallons of water; 86 gallons of gasoline; and 57 man-hours of labor.
  • High-efficiency field lighting and an automated system that shuts down lights across the whole facility at certain times each day saves the ballpark nearly $6,000 a year.
  • Office staff turn off lights and computers, and engage in other energy-saving behaviors, to help save nearly 5% on office energy use.
  • Target Field prides itself on being America's most multi-modal, transit-oriented ballpark. The ballpark is accessible via light rail, commuter rail, buses lines, bike trails, and pedestrian routes, and its website offers information on traffic so drivers can plan avoid it.

3. Nationals Park... Washington Nationals

  • Highly reflective "cool roof" materials over the concession/toilet area minimize heat gains and reduce air conditioning use.
  • Energy-efficient lighting uses 20% less energy than typical field lighting.
  • Water-efficient plumbing uses 30% less water than comparable facilities – that's a savings of about 3.6 million gallons of water per year.

4. AT&T Park... San Francisco Giants

  • Replacing incandescent lights with CFLs ballpark-wide;
  • Installing motion-sensor lighting;
  • Replacing concourse signage lighting with an infrared-type, high-output lamp controlled by a low-output ballast;
  • Converting the 18 home batting cage sports lights to LEDs;
  • Upgrading to a high-definition scoreboard that is 80% more efficient than its predecessor; and
  • Installing strip curtains in all walk-in refrigerators.

5. Safeco Field... Seattle Mariners

  • Replacing the old incandescent bulb scoreboard with a new LED scoreboard, which lowered annual electricity consumption by more than 90% (from 1.2 million kilowatt-hours to 130,000 kilowatt-hours);
  • Retrofitting men's bathrooms with low-flow urinals (which use 1 pint of water per flush, rather than 1 gallon); and
  • Recommissioning all HVAC systems.

Getting honorable mention was Miller Park... home of the Milwaukee Brewers... and Busch Stadium... home of the St. Louis Cardinals.
