The main source of freshwater is from the clouds... And the refrigerator
Steel, and plastic are the main components.
Yes, a refrigerator uses an electromagnet in its operation. The compressor in a refrigerator contains an electric motor that drives a pump, which circulates the refrigerant through the system. The motor operates using an electromagnet that converts electrical energy into mechanical energy to compress the refrigerant. This process is essential for the refrigerator to maintain its cooling function.
The compressor in a refrigerator uses electricity to compress the refrigerant gas, which causes it to release heat and transfer energy from the inside to the outside of the refrigerator.
The main uses for grains is to feed birds!:)
A 100 watt light bulb draws a little less than one amp. A refrigerator draws much more when compressor is running. The duty cycle of the light and refrigerator will ultimately determine which uses more power on a Kilowatt Hour basis.

The refrigerator typically uses more energy than the dishwasher or dryer because it runs continuously to keep the food inside cool. Dishwashers and dryers consume a lot of energy during their operation, but they are not constantly running like a refrigerator.
