I was reading something by someone who "did the math" for leaving a 400 Watt PC on for an entire year, and I thought his rate of 37 cents per kilowatt-hour was high. [more inside]
We were approached at a street fair by a somewhat high-pressure salesman. In its self something of a red flag. However, their rates and espoused business practices were intriguing. On paper (online), they seem like a good choice, especially if I'm interested in green energy. I am aware that they're owned by NRG, but this doesn't put me off on its own. [more inside]

Help me understand why the energy company seems to (somewhat randomly) choose to estimate my energy usage rather than billing me for actual usage. [more inside]
is this ConEd solutions on the level, as providing more eco-friendly electricity than my regular Con Edison provider? What are the pros and cons? The agent who is trying to sell me this says my bill will go up a little. This is for residential usage in New York City. Any experience or information on this is much appreciated.
What is "electric potential"? I've dug through the internet, gone to tutoring, asked my teacher, and nothing has helped. [more inside]
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]

Home energy advances. Are there any new developments I should know about as I'm about to move into an older single-family home after 13 years of living in an apartment? It is a gas/electric home with heavy tree shade.
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. My basics reasons are cost and that Comed, the local provider has treated me like crap over the years and I am tired of their corporate doublespeak and crappy service. [more inside]
I am looking for quantitative information on energy demand for mobile devices with low power requirements, such as alarm clocks, book lights, TV remotes – things that usually require batteries to run (but not devices with higher power requirements like smartphones or laptops). Does anyone know where I can find such information? [more inside]

I want to make my apartment more energy efficient. I don't have any control over how much heat I get, so I'm most concerned with a) making sure as little heat is escaping through the windows as possible and b) reducing the amount of electricity I use. [more inside]

First time living alone, and just got my first electric bill... what's using so much power? How much power does my computer really use? [more inside]
Should I have our small business switch to a third party green energy provider? We had a salesman for Accent Energy come to our door and he was a bit shady so I told him that I wanted to look into this on my own time. But from what I'm reading online it could be a great way to convert to a more environmentally responsible energy solution. And its Earth Day today too. Our company wants to do what we can to be "green" and we would even pay slightly more to do so, but if a switch to a third party will cost three times as much then we just cant do it. [more inside]

Since December 2006, my electricity bill has shown at least a 1,000 KWH increase over the same period a year ago. We haven't purchased any new appliances, or done anything appreciably different. This month, we didn't use our air conditioning/heating unit at all, and our bill still came in 25% higher (500 KWH) than a year ago. We're at a loss. What could be the reason? We ordered a Kill-a-watt, but till it arrives, we are trying to figure it out. Any thoughts? [more inside]
How do electric meters work? How do they measure the amount of charge you used? I suspect they must know the amount of charge that enters the home, and then they have some way to measure the amount of charge that leaves the house, but I'm really not sure. [more inside]
EnergyPurchaseFilter: What is the deal with non-regulated electric purchasing? Who's had experience with this, and was it all the [highly suspect] awesome hoopla that it's played to be by the companies/government? Bonus points if you live/have lived in New Hampshire, where I'm trying to figure out this whole mess. [more inside]
How can the energy cost of an electronic device over a span of time be calculated?
Why is electricity so much more expensive then natural gas? Am I reading my bill wrong, or is it really an order of magnitude cheaper? [more inside]
What is a good, small, inexpensive, energy-efficient space heater? Living in a leaky old house, we're starting to dread the approach of our first winter here. All we have is one crappy gas wall heater, this electricity-sucking system on the roof that pumps down solar-heated air, and a fireplace in the bedroom. We need more. (We're already going to seal the windows with plastic where we can.)
