By understanding how much power a person can produce, it should give you a good frame of reference on the scale of electric power production! As I watch the Tour they occasionally display a rider’s instantaneous power output on the screen. They are able to do this because the cyclist has a power meter on their bike and this transmits data to the broadcasting network. So just like the TED can monitor my home’s power consumption, the bicycle power meter measures a cyclist’s power production. This power usually ranges anywhere between 250 Watts if they are just cruising along with the pack, or 400-500 Watts if they are pushing hard up a steep climb.
