True that electrical devices generate some amount of heat.
Yes but for what purpose. Virtually all hpme appliances and electronic devices require ac.
Photovoltaics means to generate electricity from sunlight. Tiny photovoltaic cells are used in devices such as calculators, to save battery power. Larger systems are used to provide electricity to devices or homes that are far from the interconnected electric network.
EE is a vary broad discipline. EEs design circuit boards, design and code software, design communication systems (wireless and wired), design antennas, design computers, design EM (electromagnetic) components.... the list goes on and on.
The common household electrical service is usually rated as a single phase service. In North America there are a few 120/208 three phase services being put into larger homes.
Outside the homes, electricity is transferred at several thousand volts, for reasons of efficiency (less energy is wasted that way). This voltage is far too high for home use. (Also, home devices are set up for a specific voltage.)Outside the homes, electricity is transferred at several thousand volts, for reasons of efficiency (less energy is wasted that way).

Electric current in homes is typically supplied by the power grid and enters through the electrical wiring. The current flows through circuits to power electrical devices such as lights, appliances, and electronic devices. It is important to use proper wiring and circuit protection to ensure safety and prevent electrical hazards.
Outlets are devices that provide a connection point for electrical devices to receive power from a building's electrical system. They work by allowing electricity to flow from the wiring in the walls to the device plugged into them. Outlets play a crucial role in electrical systems by providing a safe and convenient way to power various devices and appliances in homes and buildings.
100 amp service refers to the electrical capacity of a home or building’s electrical system, indicating that it can handle a maximum of 100 amperes of current. This rating determines the amount of power available for appliances and devices; it’s essential for ensuring that the electrical system can support the needs of the occupants without overloading. In residential settings, 100 amp service is typically sufficient for smaller homes or those with fewer electrical demands. Upgrading to higher amperage can be necessary for larger homes or modern electrical needs.
-- The electrical devices that we've become accustomed to using in our homes need much more power than any reasonable amount of fruit can deliver. -- The electrical devices that we've become accustomed to using in our homes operate on AC, whereas fruit delivers DC. -- When you take into account the energy and other resources required to plant, grow, harvest, distribute, install, operate, and maintain fruit, it isn't that much of a bargain compared to the current methods of mass producing electrical energy. -- The whole notion of turning food into fuel for cars, TVs and washing machines is demented.

The advantages of using 2 prong outlets in older homes include simplicity, cost-effectiveness, and compatibility with older electrical devices.
By turning off lights or other devices you don't use and by installing energy-saving equipment (especially lights).
Solar energy can be converted into electricity through the use of photovoltaic cells or solar panels. These devices capture sunlight and convert it into electrical energy that can be used to power homes, buildings, and devices.
Electrical current can travel through a conductor, such as a wire, to energize devices and homes. It can also travel through the air in the form of electromagnetic radiation when using technologies like wireless charging or radio transmission.
Mains sockets are electrical outlets designed to connect devices to the power supply. They provide access to electricity for devices such as lamps, appliances, and chargers. Mains sockets are typically found in homes, offices, and public spaces for powering various electrical devices.
