I looked at your link, but it only mentions Indiana.
Is there something about Indiana's geographical position in their Time Zone that nullifies DST's advantages?
An early goal of DST was to reduce evening usage of incandescent lighting, formerly a primary use of electricity.[6] Although energy conservation remains an important goal,[24] studies are contradictory, and suggest that DST can increase energy use in some common cases:
* The U.S. Dept. of Transportation (DOT) concluded in 1975 that DST might reduce the country’s electricity usage by 1% during March and April,[25] but the National Bureau of Standards (NBS) reviewed the DOT study in 1976 and found no significant energy savings.[21]
* In 2000 when parts of Australia began DST in late winter, overall electricity consumption did not decrease, but the morning peak load and prices increased.[26]
* Although a 2007 study estimated that introducing DST to Japan would reduce household lighting energy consumption,[27] a 2007 simulation estimated that DST would increase overall energy use in Osaka residences by 0.13%, with a 0.02% decrease due to less lighting more than outweighed by a 0.15% increase due to extra cooling; neither study examined non-residential energy use.[28]
* A 2007 California study found no clear evidence that electricity would be saved through the earlier start to DST that year,[29] and although one utility did report a decrease in March 2007, five others did not.[30]
* DST may increase gasoline consumption: U.S. gasoline demand grew an extra 1% during the newly introduced DST in March 2007.[31]
* A 2007 study estimated that winter daylight saving would prevent a 2% increase in average daily electricity consumption in Great Britain.[32]
* A 2008 study examined electricity billing data in Indiana before and after it adopted DST in 2006, and concluded that DST increased electricity consumption by 1% to 4%.

It’s the recent change in how Indiana handles DST that makes it a useful case study. Up until very recently parts of Indiana didn’t do DST and now the whole state does, thus comparison can be made that are over a short enough time period to rule out things other than DST (technology, variant weather).
Of course the funny part is that AZ uses the exact same “it saves energy” reasoning to not do DST that the pro-DST people are always using. Somebody must be wrong. And if you pay attention to the lighting habits of the world you’ll see it’s the pro-DST people, lights tend to be on where people are doing, day time, night time, doesn’t matter, the lights are on if somebody is home (or working, it’s really the business space that burns more electricity).
I’ve been reading most farmers don’t want it..so there’s the agiculture lobby against it, maybe that’s the real case in Indiana. I don’t know what is true but I think if the animals can adjust to 8 months of it they could probably go for a year of it.
Personally, I love it.
