From a pocketbook perspective this price is great - in fact it's been several years since we've seen prices this low in the National Capitol Region.
Problem is, lower gas prices severely underprice the environmental impact of their associated carbon emissions. So while many educated and well meaning people are trying to reach an agreement in Paris to address our growing Climate Crisis, they are being undermined by the local economics of cheap gas. Unless we can change the economic incentives, all the Paris's and Kyoto's in the world won't save us from our own hubris.
