I Can't Help Myself

We received a sales catalog in the mail from a large national toy store. One of the items featured was an electric bike. Didn't know they made those. Looks to be similar to the moped. Now, in addition to wondering why kids need electric bikes, I also wondered how they can tout the bike as Green!Clean! Why, oh why, is electricity clean? I understand that someday soon HopeyMcChange will magically fix this, but I was under the impression that currently, burning fossil fuels is not, in fact, green. Now, the kids just *riding* the bikes themselves? That sounds pretty green.
