Is it possible for an alternator to run at a normal power output at 2000rpm, but not at idle (yes it's above 800rpm)? I ask this because my car won't start and I get no response from anything when I turn the key except the clock is fading in and out. The only reason I can think of why my battery is dead would be the above scenario.

yes. it should always put out about 14 volts regardless of engine speed.
