find someone with an electric lawn mower you can borrow, mow a yard with it and contrast the difference between the amount of electricity used and where it came from(coal, wind, oil, etc...) and what gasoline would cost along with its bad environmental effects. they sell cheap watt meters these days that you can use to determine electricity used. include costs for oil changes and associated costs for reclaiming and reuse of the old oil. if you teacher wants you to do the project over several weeks time, then do multiple lawns and gather more data. you could even look up an instructables article about converting a lawm mower to propane cheaply, then compare them all.
