Scientists: Strong solar storm heading to Earth (Update)
A strong solar flare is blasting its way to Earth, but the worst of its power looks like it will barely skim above the planet and not cause many problems.
Experiment makes energy savings a game
Let's face it: We're energy hogs. We want more light, we flip a switch. If we're hot, we crank up the AC, without a second thought on the power grid strain. It's what economists call inelastic demand – the resource is widely ...
