The unintended consequence of using LED lights to save energy in traffic lights is having a down side, including the death of one woman.
I've got an idea, they could string some of those coiled heating units people use to melt snow on their roof and melt the ice that way. Might defeat the old energy savings realized by the LEDs though.
My science teacher wife laughs every time she hears people touting the new electric cars or hyrid vehicles. She points out that when you plug the car in to recharge the energy, that electricity has to be made somewhere, often with coal, oil and if you live in Buffalo the more earth friendly water turbines.
Of course, nuclear would be a cleaner solution for producing energy, but no one wants to talk about that any more.
We are one of those energy conserving homes with the new bulbs. I don't like the light they put out and from what I hear, if you break one you then have a mercury emergency to deal with.
Just to let you know, if I break one they'll be no hazmat situation, because I will brave the mercury spill, sweep up the mess and throw it into the garbage. I think the earth, and I, will survive.
