electrical energy, usually 110 Volt or 220 Volt here in the U.S.
Also, natural gas is used as an alternative to elecrtical in kitchen stoves, furnaces, and water heaters.
The number of appliances that can be used in 3.5 kWh depends on the energy consumption of each appliance. To calculate, divide 3.5 kWh by the average energy consumption of each appliance in kWh to determine how many can be used.

Water energy, or hydroelectricity, is used for powered homes and its electrical appliances.
Solar energy is used by many to power appliances and machines in homes and businesses. It is also used for heating and cooling purposes.
If by switching you mean upgrading, the new appliances are more efficient energy users. Therefore, less energy is used to do a comparable amount of "work".
All home kitchen appliances use electrical energy.
Nuclear energy is not used in typical kitchen appliances or cooking processes. Most kitchen appliances run on electricity generated from sources such as natural gas, coal, or renewable energy. Nuclear energy is primarily used in power plants to generate electricity on a large scale.
Appliances do not produce electric energy. Electric generators, such as power plants or solar panels, are examples of devices that produce electric energy. Appliances consume electric energy to perform their functions.
Most appliances produce heat as a byproduct, which is considered wasted energy. This heat is generated when the appliance operates and is not used for its intended function, leading to inefficiency. Proper insulation and design can help reduce this wasted energy.
Energy can be used for cooking and heating up water. It can be used for lighting and electrical appliances as well, such as televisions, fans etc. In some ways, anything involving the switching on of a switch can be said to use energy.
