>additional spare capacity in the wires 1. What additional spare capacity? Why would any particular electrical installation (here, streetlights) be designed for about an order of magnitude more carrying capacity? 2. One of the original motivators for near-universal lighting of roads was to use the night-time baseload of power stations that could not be turned off (ie, nuclear and coal). Now that we use much more intermittent sources, this "free" energy just doesn't exist. It may be that switching to energy-efficient street lighting just makes up for this shortfall, leaving no spare power. |
