It depends entirely on what sort of clock it is. If it is one of the old wind up clocks with the bells on top, mechanical energy is converted into kinetic and sound. If it is an electrically powered clock, likely the energy would be electrical to sound (kinetic or EM).
it uses sound energy
Electrical Energy to power the sound.
In a quartz clock, the cell has chemical energy. it will converted in to kinetic energy.
chemical energy--->mechanical energy--->sound energy
there is electricl light kinetice and potential energy

Some examples of a cool alarm clocks are: Silent alarm clock, Wifi Donation Alarm Clock, Bacon Alarm Clock, Flying Alarm Clock, Light Sleeper Alarm Clock, Banclock, Danger Bomb Alarm Clock, to name a few.
In mechanical clock, when spring is revolved, it becomes a potential energy. when spring is released, it will converted in to kinetic energy, so that the hand of the clock is rotated.

The iPhone comes with a clock app already installed that has an alarm clock features. This is the best alarm clock that I have found so far. Other popular alarm clock apps are:CARROT Alarm - Talking Alarm ClockWake Alarm ClockSpeakToSnooze ProSleep Cycle Alarm ClockWake n Shake Alarm ClockRise Alarm Clock

A clock radio and an alarm clock are two very similar things which provide some of the same functions however they differ in their features. An alarm clock is a basic clock which has an alarm function and a clock radio combines the use of an AM/FM radio and an alarm clock.
