Power went out... right as I'd gone to the grocery. I put all the must-stay-cold stuff away anyhow because the stuff I'd bought was worth more than what was already in there. So, it's been opened once, what was put in was still frozen/cold from the grocery. I'm not opening it again. How long can I expect stuff to still be good for? [more inside]

Please help me understand this bizarre home electrical-wiring problem, and how to fix it. I've got a mid-50s house. I wanted to put an outlet into the second bathroom, which has none, and it looked like the easiest way to do that would be to replace a wall switch with a combination switch/outlet (specifically, this one).

I am considering changing my electricity provider and I have never done this before. What I want to know are what things should be considered before making a switch such as this.

I just installed a new lightswitch in my bathroom. Now, when I turn my living room air conditioner OFF, the power in most of my apartment goes out. And even when the AC is on, the power level is extremely low. WTF??? [more inside]
In 2009, 91.2% of Seattle's electricity was from hydroelectric sources, and in 2010, 87.9% was hydro. Is the hydro capacity maxed out, or will it scale up to meet additional demand and maintain that ratio? Here's what I'm getting at: If I were to use more electricity than now, will that incremental power effectively come from non-renewable sources rather than ~90% hydro?
Correct way to put a 110V (three-prong) dryer onto a 240V circuit? Or should we just throw it in and get a new one?

I moved into a flat in London in Sept 2011. I wasn't given any meter readings---my agency didn't have them and didn't even know where the meters are. Landlord also doesn't have a good idea where they may be. I don't know previous tenants. There is no gas in this flat---it's electricity only. [more inside]

A friend of mine has 20+ old arcade games in his basement. He has essentially set up a small arcade museum at his house. It's pretty sweet! The games are split between several circuits in the house but power is becoming a concern. These old electronics are sensitive to spikes and low voltages and we want to keep them running as long as possible - most of the circuit boards are not made and difficult to replace or repair. What should we consider for 110v line conditioning? [more inside]

Can a math / electrician whiz help me figure out how much my little space heater is costing me to run? The heater is listed as 120V 60Hz 1500W, and I run it on its highest setting for about 8 hours a day. According to my last utility bill, my electric was $118.64 for 1536 kWh, or $0.077239583 per kWh. So how much is this little heater costing me to run per hour?

What's the most accurate answer I can give her that she will understand and not be bored by?

Our 11 year old refrigerator stopped getting cold enough (42 to 48 degrees). It's done this before and we've replaced parts. This time I decided enough and replaced the unit. Now this new LG refrigerator is doing the same thing. I've had a tech come out and they replaced the board with all the pertinent parts and it still isn't getting colder. But I've plugged in our old unit in the garage, where it is cooler, and now it's at the correct temp. Is it possible that it can be something to do with the electrical outlet? Wouldn't the service guy have had something to test that?
