rtc0 high interrupt rate

Lately, I've been experiencing increased power usage on my laptop. I tried launching powertop and this is what I saw:

Wakeups-from-idle per second : 471.1    interval: 5.0s
no ACPI power usage estimate available

Top causes for wakeups:
  76.1% (1025.4)   [rtc0] <interrupt>
   8.2% (111.2)   chromium
   4.5% ( 60.0)   [radeon] <interrupt>
   3.8% ( 51.2)   [kernel scheduler] Load balancing tick
   2.3% ( 30.6)   [ath9k, snd_hda_intel] <interrupt>

Why rtc0 has so many interrupts and any idea how to fix this?
