Electricity Overload Leads to Bad Energy Saving Decisions

Do you suffer from "electricity overload"? We don't mean the number of plugs crowding your outlets. We mean the short circuit in your brain when you try to figure out: Do you save energy by turning lights off for only a few minutes? Which takes more energy: leaving air conditioning on all day or cooling your house after you come home at night? What is a watt? Do I pay twice as much for an appliance running on 240V as one on 120V?

One can dream about nuclear power or a hydrogen economy, but the best way to deal with a shortage of energy is to eliminate waste. Seven to ten percent of electricity is wasted through transmission losses, and the North American transmission infrastructure is a creaky, leaky mess. But it is almost impossible to get approval for new transmission lines; between aesthetics and EMF, nobody wants them in their backyard.

Superconducting cables to the rescue: they lose almost no electricity, radiate almost no EMF and can be discreetly buried. "This will be a way to move massive amount of pow...

Ooooh, there is nothing lovelier than a floor-to-ceiling window, and there are few better ways to waste energy, given the low R-value of most glass. Until now, that is, when you can throw electricity out the window with Thermique. This new invention burns up to 25 watts of electricity per square foot by turning the glass into an electric heater . They say it is more energy efficient because it eliminates drafts, and the conventional heating system doesn't have to work as hard." With heated windows, you can lower the set-back temperature for your HVAC system without changing the indoor temperature. The g...
