Why Do Conservatives Like to Waste Energy?

When the lights went off during Beyonce's halftime set at the last Superbowl, conservative commentators from the Drudge Report to Michelle Malkin pointed blame (erroneously) at new power-saving measures at New Orleans' Superdome. And one recent study found that giving Republican households feedback on their power use actually encourages them to use more energy.

Why do conservatives, who should have a natural inclination toward conservation, have a beef with energy efficiency? It could be tied to the political polarization of the climate change debate.

A study out Monday in the journal Proceedings of the National Academy of Sciences examined attitudes about energy efficiency in liberals and conservatives, and found that promoting energy-efficient products and services on the basis of their environmental benefits actually turned conservatives off from picking them. The researchers first quizzed participants on how much they value various benefits of energy efficiency, including reducing carbon emissions, reducing foreign oil dependence, and reducing how much consumers pay for energy; cutting emissions appealed to conservatives the least.

The study then presented participants with a real-world choice: With a fixed amount of money in their wallet, respondents had to "buy" either an old-school lightbulb or an efficient compact florescent bulb (CFL), the same kind Bachmann railed against.

Both bulbs were labeled with basic hard data on their energy use, but without a translation of that into climate pros and cons. When the bulbs cost the same, and even when the CFL cost more, conservatives and liberals were equally likely to buy the efficient bulb. But slap a message on the CFL's packaging that says "Protect the Environment," and "we saw a significant drop-off in more politically moderates and conservatives choosing that option," said study author Dena Gromet, a researcher at the University of Pennsylvania's Wharton School of Business…

Gromet said she never expected the green message to motivate conservatives, but was surprised to find that it could in fact repel them from making a purchase even while they found other aspects, like saving cash on their power bills, attractive. The reason, she thinks, is that given the political polarization of the climate change debate, environmental activism is so frowned upon by those on the right that they'll do anything to keep themselves distanced from it.

"When we're given an option where the choice is made to represent a value that we don't identify with or that our ideological group doesn't value," she said, "this can turn the purchase into something undesirable. By making [the environment] part of the choice, even though they might see the economic benefit, they no longer want to put their money toward that option."

Unlike conventional lighting systems where rated average life for a lamp is the point at which half the lamps fail, useful life for an LED is hard to estimate since catastrophic failure takes so long to occur. In fact, LED light sources continue to give light even after their initial lumen output has decreased by 50%.

To determine knowing how long an LED fixture will retain a considerable percentage of its initial luminosity, lumen maintenance measurements are used instead of meantime to failure measurements. The lumen maintenance specification for an LED is typically the time it takes for an LED to reach 70% of its illumination. This 30% reduction in light output is considered to be at the threshold for visually detecting a gradual reduction in light output.
