I’ve always heard conflicting things, as to whether daylight time saves energy or not. That’s supposed to be one reason to have daylight time.
Current LED technology put that question to rest. Further savings could probably be made by adopting internet connected motion sensors/public wifi repeaters on everything, including street lights.
Rubio's Florida is much closer to the equator, where sunrise/sunset varies little throughout the year. Living in freezing cold northern states only made sense when it kept out the wild equator psychopaths, which thanks to Demonrats is no longer the case. The energy consumption/carbon emissions from home heating in northern states no longer has the same quality of life benefits, and solar there doesn't make sense.
The reason most of Arizona is on year-round standard time is that daylight savings time, when tried in 1967, proved to increase air-conditioning energy use significantly for businesses and government offices.
They proved that wrong.
