Varies dependent on brand and model. For a specific one, go to the website for the manufacturer.
52 kilowatts per hour
That varies widely among different refrigerators. But you should ask your question slightly differently. Kilowatts would refer to how much power the fridge is using at a single instance. I you are concerned with power usage over a year, you need to multiply by time, ie kilowatt-hours (commonly seen as kWh). This is the unit the power company charges you by. Look for a sticker on your fridge, all modern ones will have one that tells you the yearly kWh consumption.
A kilowatt is 1,000 Watts. 30 Watts is equal to 0.03 kilowatts. A kWh or kilowatt-hour is the rate of electrical usage. It is a measure of kilowatts used per period of time (1 hour). 1 kWh is 1 kilowatt (1,000 watts) for 1 hour. So, multiply your 30 watts (0.03 kilowatts) by 1 hour to get kWh. =0.03 kWh In about 33 hours and 20 minutes, this lamp would use 1 kWh.
Watts is smaller than kilowatts. watts is unit of power and kilowatts hour is unit of energy. Electrical devices are specified in watts where as electrical bill is for kilowatt hr use.
It's usually an output of 75 kilowatts in the body.

One watt is 0.001 kilowatt. 65 watts is 0.065 kilowatts. It does not matter what the voltage is - watts are watts.
52 kilowatts per hour
While it varies based on the size / efficiency rating of the refrigerator, the average fridge (17 cu ft) uses about 110kW
0.04 kilowatts one kilowatt is 1000 watts
A 400-watt light uses energy at the rate of 0.4 kilowatt. In 1 hour, it uses 0.4 kilowatt-hour of energy.
Anything that uses 40 kilowatts would use 40 kilowatt-hours for each and every hour.
About .000034 kilwatts
Energy-saving bulbs use much less than 1 kilowatt and most of them use less than 40 watts which is 0.04 kilowatts. A 20 watt bulb uses 1 kilowatt-hour of energy if run for 50 hours.
It depends what the power rating of the appliance is. A 500 watt microwave will use half a kilowatt if it's run for an hour on full power. A 750 watt unit will use 3/4 of a unit in the same time period.
