There seems to be a lot of concern about how much money other people are spending on electricity for their Christmas lights. I’m happy to report, it doesn’t cost much.
The price of electricity varies from place to place, and from time to time, but a typical price is 12¢ per kilowatt hour. That means that if you burn 1,000 watts for the span of one hour, you’ll pay 12¢.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Only flaw in Rob’s analysis is that the doesn’t actually compute the total cost. How many hours on average plus how many days. At almost a dollar an hour for some of them, imagine a very very (unrealistically low) minimal 5 hour usage, at 20 days? That’s a hundred dollars right there.
Fun survey, but I’d like to know how to get electricity in California for $0.12/kWh. My previous holiday lighting rig was about 500 watts. Since we are always bumping into tier 4 with PG&E, any additional juice tends to cost about $0.34/kWh.
That’s why I’ve gone to nearly all LED holiday lighting this year – including a big 40 pixel 36mm RGB strand from Adafruit!
