Here's an interesting (and short) article from the WP regarding electricity use and incentives. Obviously it's a complicated issue, but interesting in that both producer and consumer face incentives to reduce electricity.
Here is a short video describing an incentive to reduce energy use from Duke Progress. $25/year isn't much of an incentive, but I just signed our house up to check it out.
With regard to the article, what are the incentives for the producers? What are the incentives for consumers?
With regard to the Duke incentive, why are they doing this?
Other than reducing your power bill, what are some other examples of economic incentives to reduce electricity use?
