We can build cars that run on batteries for a pretty long time and we have hybrids that use gas to charge the batteries and the other way around. Getting tired that every second of the day I am running on gas. If I am not in my truck using gas then I am on my mower, if I am not on my mower then I am using my grass trimmer, if I am not using the gas on my trimmer I am in my truck again driving..................... Does anyone feel what I am saying. Just imagine the money you will recoup if our business didn't use gas, but then again everybody would realize how much profit there is in landscaping then the market would get more saturated.
