My mom uses AEP electric and her bill is pretty outrageous, but she doesn't want to cut down on her usage. I think I have seen advertisements before, for some no name company that will provide the same electricity for 10% to 30% cheaper. Who was it and is it legit? What are my other options for switching electric companies/lowering my electric bill. I already had her sign up for low income assistance Thanks.
I'm in over my head on a DIY project involving electrical terms I don't understand. I want to use a solar panel to power both a water pump and a computer fan, and need to know if this is possible with the components I have, and if possible how can I splice/connect these non-matching wires?

I am traveling to Chennai, India this October. I will be bringing my Mac Book Pro and assorted accoutrements (iPad, iPhone, etc.) with me. Does the Apple World Travel Adapter kit provide connectivity to Indian electrical power outlets? If not, what does? Thanks.
There was a huge lightning storm this morning, in the middle of it my power went out. All the breakers on my boat are on, all e breakers on the power bollard are on. The odd thing is that the bollard has power to the meters and register 5v on the ac setting of my multimeter across live and earth. Also the RCD buttons trip out the breakers. This suggests that it has power. But nothings coming out. Any ideas for a) How come it has some power but no output b) Is there anything I can do. My electrical skills = I own a nice multimeter My fear of zappy death = relatively high [more inside]
We had an electrical incident where I work a couple of nights ago, and I'm trying to wrap my brain around it. Our house engineers have maintained systems at 150 amps on legs with 200 amp fuses. The power company reported a power dip, shortly after which we blew two of the 200 amp fuses. What happened? We had a drop in available voltage, so our amperage demand shot up? [more inside]

We've had PG&E SmartMeters installed at our building for awhile, and our landlord is very concerned about the health risks and surveillance risks he believes they pose. He's sent us a bunch of "literature" to read and it all reads like wackadoodle conspiracy theories with no basis in science, as does everything else I've found online. As easy as it is to just roll my eyes and dismiss his concerns, I feel like I should make a good faith attempt to discover if there's really anything to be concerned about. Are there any good, reality-based reasons to be anti-SmartMeter? Any science-based studies from reliable sources on their safety? Any well-thought-out articles on the subject that don't include the phrases "molecular earthquakes" or "like hundreds of cell phones being on at the same time"? Help a skeptic out!
I just got an automatic watch and the fact that it powers itself via small movements of my wrist has me fascinated, and also puzzled that we haven't really taken more advantage of obtaining small amounts of power via changes in kinetic energy (if thats the right term?) [more inside]
I once read a great article explaining why we use polarized plugs, grounding, and GFCI outlets in household AC circuits. It was written from the perspective of an electric company whose customers keep getting electrocuted by their appliances. The company introduces the safety measures one by one and the article explains how people still get shocked. It might even have been a comment on Metafilter; I'm not sure. Where can I find it?

I just bought a subwoofer from a thrift shop, but unfortunately the power adapter (13.5 AC in) is missing. My neighbourhood shops seem to be fresh out of adapters with that voltage, so I'm wondering if it would be possible/safe/advisable to use a different adapter? I have several lying around the house with output voltages ranging from 5 to 16V.

I'm moving to Germany in a couple of months and have a few questions about using various 110V US-purchased appliances on the local 220V power. Specifically the 50Hz/60Hz issue - how big of a deal is it? My understanding is that anything with a motor may have a shorter lifespan and run somewhat less efficiently (and of course anything that uses AC for timing will run slow), but any other issues?

So instead of providing an answer, please help me by showing me how you got your result. I have a 12v device that consumes 1W in idle mode, and 5W in active mode.

We woke up this extremely cold morning (9F/-13C) and various electric things in our condo seem to be flaky, like there's not enough power.

Since it's all electric, it seems like it might be related. [more inside]
Nearly 12 years ago I underwent cranioplasty, which involved dissimilar metals being added to the inside of my skull. Could it be possible that I'm generating a low voltage current? This would explain roughly 90% of the unexplained symptoms I've noticed since that time. This seems like a case of electrochemical capacitance to me. I understand that YANMD; in fact, it may even be the case that YARNAD. That's just fine, I don't really want anyone's 'medical' advice. What I need is some advice on what questions to ask and which specialists I 'should' actually be seeing to properly diagnose and resolve these issues. [more inside]
I know this question is a little bit arbitrary, but any response will be helpful. I live in a 2 family spilt house/condo. I noticed that my electrical box is powering the OTHER unit's gas boiler. I assume that the electrical just feeds the thermostat and maybe triggering the pilot to boil the water?? (My knowledge here is limited.) Without knowing too much about their heating use, I am trying to determine the urgency of getting an electrician to switch it from my electricity to the other unit's electrical box.

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.

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?
