Re: Gas or Electric
How about using native landscaping and not mowing (plus conserving
More directly to your question I urge you to read an article in
Environmental Science and Technology, Vol. 34, No. 22, pp. 4789 -4796 by
Micheal Overcash, et. al. in which they compare the underlying data and
assumptions used in different life cycle assessment models.
They did not look at mowers but did look at power generation by various
energy sources. The papers gives an idea of the tradeoffs and the
limitations to our understanding and basic data. Everyone dealing
with LCA type issues should be required to read this article. You
might be able to get the article at:

While I believe it is electric, a colleague of mine believes that the
loss in efficiency due to transfer means that the electric utility
company has to burn more fuel to power the mower. This loss in
efficiency could offset the benefit of having a controlled
I suppose it also depends on the fuel at the plant, and wether the mower
has a catalytic converter.
We both agree a push mower is a great alternative, though neither of us
will actually get out and use it. Push mowers also have a
"waist" minimization effect.
