To get around the lack of power longevity, we still rely on gasoline-powered triplexes for verticutting. Contrast these cons, however, with the many pros of having all-electric equipment. In the case of The Bear Trace at Harrison Bay, we've eliminated thousands of gallons of fuel from our operation every year, which, in ad - dition to significantly cutting expenses, has in turn eliminated point source carbon emis - sions, thus softening our environmental foot- print, improving air quality on the course, and decreasing health risks to employees. We've also reined in our noise pollution to a reason - able and legal level, enhancing the well-being and on-course enjoyment of both employees and golfers. What the future holds For years, golf cart manufacturers have been using and improving electric technol - ogy to better serve their clients, and some golf course maintenance equipment manufactur - ers are now seeing the benefit in pursuing a line of fully electric equipment. The future looks to bring more-efficient electric motors, along with rechargeable solar panels that can be attached to the mowers to feed the batter - ies while the machines are in operation or are parked outside on a sunny day before being stored indoors overnight. Lithium-ion-based power sources will most likely overtake lead-acid battery systems as the most economical and environmentally sound power source for electric equipment.
