It's a consistent claim because it is consistently true. The world does not generally operate 24/7 -- parts of it do, but most of it does not. And we (humans) tend to sleep at night. While we're sleeping, we use less electrical power. I mean: Think of all the things you (or any other person) might do in a normal day. Just list them out -- mentally, on paper, or whatever. Regular things, like work or school, or laundry, or eating food. And now, you have a list of stuff that you generally do not do when you're sleeping. So now, it should be intuitively obvious that energy consumption is reduced at night. Here's some charts for different regions of the US that demonstrate that demand is lower at night, consistently, across all regions and all seasons: https://www.eia.gov/todayinenergy/detail.php?id=42915 https://www.eia.gov/todayinenergy/detail.php?id=42915 And some data from Alberta (home of the frozen gas pumps being discussed here) that also shows this trend: https://www.aeso.ca/market/market-and-system-reporting/ https://www.aeso.ca/market/market-and-system-reporting/ And another link that shows it for the UK: https://electricityproduction.uk/total/?t=7d https://electricityproduction.uk/total/?t=7d How deep do you want to dig? https://www.eia.gov/electricity/gridmonitor/dashboard/electric_overview/US48/US48 https://www.eia.gov/electricity/gridmonitor/dashboard/electr...
