Lawn mowers typically use either gasoline or electricity as their primary energy source. Gas-powered mowers rely on internal combustion engines that burn gasoline to generate power, while electric mowers use batteries or plug into an electrical outlet for operation. Some newer models utilize rechargeable batteries, providing a quieter and more environmentally friendly option. Additionally, there are also robotic mowers that operate autonomously, powered by electricity.
