Compact Florescent Lifespan

My family's been wanting to upgrade to compact florescent for years, but we've always found they burn out quickly thanks to our flaky power surges. Would dimmable bulbs be helpful, or is there some sort of inexpensive power conditioning that can be added to light sockets? [more inside]

Press Button to Cross

How does the button on the pedestrian crossing lights work? Does it actually send some sort of signal to the traffic lights, or is it just a psychological thing? It seems rather random timing-wise.

should we switch to a green energy provider?

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]

Help Me Convince The Electric Company That We Are Not Going To Stiff Them

We received a menacing letter today from our electric provider. They stated that since our last few bills have been late (which I don't dispute) we will now be required to pay a $200 "security deposit"... BUT... We have a 13-year payment history with them, at the same address, so where is the logic in suddenly requiring a "security deposit" that we obviously can't afford? Is there any way I can convince them to not do this to us? Please read the background info inside before responding. [more inside]
