Of course, he offers absolutely nothing to back up this absurd assertion.
If you wake and rise by the clock, then you use an hour's less artificial light in the evening, and typically NOT an hour's more light in the morning.
And lights are the vast majority of home energy use.
It doesn't affect stoves, clothes dryers, etc. one way or the other.
You could argue that the savings are not worth the cost (extra accidents? don't know if that's true) but to argue that there are no savings is pure bunk.
DST has somewhere between no and negative effect on electric usage. It’s daylight now my lights are on.

The US Dept. of Transportation (DOT) concluded in 1975 that DST might reduce the country’s electricity usage by 1% during March and April,[14] but the National Bureau of Standards (NBS) reviewed the DOT study in 1976 and found no significant savings.[81]
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.[82]
In Western Australia during summer 2006–07, DST increased electricity consumption during hotter days and decreased it during cooler days, with consumption rising 0.6% overall.[83]
Although a 2007 study estimated that introducing DST to Japan would reduce household lighting energy consumption,[84] 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.[85] This is probably because DST’s effect on lighting energy use is mainly noticeable in residences.[14]
A 2007 study found that the earlier start to DST that year had little or no effect on electricity consumption in California.[86]
A 2007 study estimated that winter daylight saving would prevent a 2% increase in average daily electricity consumption in Great Britain.[87] This paper was revised in October 2009 .[88]
A 2008 study examined billing data in Indiana before and after it adopted DST in 2006, and concluded that DST increased overall residential electricity consumption by 1% to 4%, due mostly to extra afternoon cooling and extra morning heating; the main increases came in the fall. The overall annual cost of DST to Indiana households was estimated to be $9 million, with an additional $1.7–5.5 million for social costs due to increased pollution.[89]
The US Dept. of Energy (DOE) concluded in a 2008 report that the 2007 US extension of DST saved 0.5% of electricity usage during the extended period.[90] This report analyzed only the extension, not the full eight months of daylight saving, and did not examine the use of heating fuels.[91]
