I'm all for new technology and eco-friendly transportation, but it's hard for me to get excited about electric motorcycles-at least in their current state-for a number of reasons. Batteries have to be charged, and that power has to come from somewhere. More often than not, it originates in a power plant burning a nonrenewable resource such as coal or natural gas, with the resultant CO2 and other harmful emissions. Granted, the overall efficiency and environmental impact of using mass-generated electricity is much better than an independent internal combustion engine, but electric bikes are far from what you'd call zero-emissions. Late last year California Governor Arnold Schwarzenegger issued an executive order calling for at least one third of the state's energy needs to be met by renewable resources by 2020, but a recent story in the Los Angeles Times indicated that this will be a difficult goal to meet. Taxing the system even more by adding droves of electric automobiles and motorcycles will put that goal even further away.
