The bulk of the energy lost is due to the resistance of the transmission lines - the so-called I squared R loss. The squared bit of this explains why long distance lines run at such high voltage; if you multiply the voltage by 10 the current reduces by a factor of 10. The I2R loss then reduces by a factor of 100. Actual lines increase the voltage by more than a thousand times, thus reducing losses more than a millionfold.
There are some other losses due to
- eddy currents in the Transformers
- capacitive leakage
- corona discharges
- skin effect. This last one is why some of the extra-high-wattage links use DC.

How is energy lost whilst electricity is being transmitted?
Energy is lost during electricity transmission mainly in the form of heat due to resistance in the wires. This phenomenon is known as transmission loss. The longer the distance the electricity travels, the more energy is lost. Upgrading infrastructure and using high-voltage transmission lines can help reduce these losses.
How is the energy lost using wind energy?
Energy can be lost in wind energy generation through factors like friction in the turbine gears, transmission of electricity over long distances, and conversion losses when transforming wind energy into electricity. Additionally, not all wind that passes through a turbine can be captured, resulting in some energy loss.
Why energy is lost from power transmission cables?
Energy is lost from power transmission cables due to resistance in the materials used to make the cables. When electricity flows through the cables, some of the energy is converted to heat as it encounters resistance, causing a loss of efficiency in transmitting power over long distances.
How is energy lost from power stations to homes?
Energy is lost during the generation, transmission, and distribution of electricity from power stations to homes in the form of heat due to resistance in power lines and transformers. This energy loss is known as transmission and distribution loss, and it occurs as electricity travels long distances over power lines. Transformers are also used to step up or step down voltage, which can result in additional energy loss.
What happens to the lost energy when fossil fuel is used to generate electricity?
Energy is never lost, it is transformed into different types or transferred into different systems. Some of this is useful energy, for example thermal energy used to power a turbine or generator. Some of this thermal energy is not useful, and instead just heats up the fuel container or components of the generator. This energy has still come from the fossil fuel being burned, but it has not been transferred into the system for generating electricity.

If an alternator powers an electric motor that turns the alternator will there be extra usable energy?
No.All alternators, generators, and motors lose some of their mechanical and/or electrical energy to heat. The alternator converts mechanical energy into electricity, but some of that mechanical energy is also converted into heat (through friction and transmission loss), and the heat is lost to the environment. Similarly, an electric motor that converts electricity into mechanical energy also loses some of its energy to heat, also through friction and transmission loss. It is important to note that the energy is never truly lost - all the energy is accounted for - but the energy dissipated as heat is no longer available to the electrical / mechanical system.Let's assume that the motor and alternator are 99% efficient - that means that they lose only 1% of their energy to heat and transmission loss. You can imagine, then, that after a moment, there is only 99% of the energy left, and then 98%, then 97%, and so on until the system exhausts all of the energy through friction and transmission losses, at which point the system stops.NOTE: Purists will argue that an alternator actually needs a battery to initially generate electricity, and that the above discussion only applies to a generator - while true, that point is beyond the scope and relevance of the above discussion.

What are three ways in which Energy can be lost?
Heat loss: Energy can be lost as heat when systems are not perfectly efficient, such as in engines or appliances. Mechanical work: Energy can be lost as kinetic or potential energy when performing work, which may not all be converted efficiently. Transmission losses: Energy can be lost as it is transmitted over long distances through mediums like wires, where some energy is dissipated as electrical resistance.
What are some properties of current electricity?
transmission lines
What happens to the energy that is not usually transferred by the solar cells?
The energy that is not converted into electricity by solar cells is typically lost as heat. Solar cells are not 100% efficient at converting sunlight into electricity, so some energy is wasted in the form of heat as a byproduct of the conversion process.
How is energy transferred in a torch from the battery to the bulb - is it by electricity - is it by light - is it by sound - is it by thermal energy?
Energy is transferred in a torch from the battery to the bulb primarily by electricity. The battery provides an electrical current that flows through the circuit inside the torch, ultimately powering the bulb to produce light. Some energy may be lost as thermal energy due to resistance in the circuit, but the main transfer mechanism is through electricity.
How is energy wasted by the National Grid?
Energy is wasted in the National Grid through transmission losses, which occur as electricity travels long distances over power lines and some energy is lost as heat. Inefficiencies in power generation, distribution, and consumption also contribute to energy wastage in the grid. Additionally, standby power from appliances and devices on standby mode can result in energy being wasted.
