National Grid Network in efficient energy?
Answer:
The grid enables a diversity of suppliers situated close to the energy source, eg wind turbines on a windy site; or to site pollution & dangerous processes away from areas of high population eg nuclear reactors on remote coasts.
High voltage transmission lines & transformers have very low losses.
hence Tesla was able to supply New York from Niagra Hydro-electric, unlike Edisson's DC supply.
about 60% from coal to end use energy.
Main losses are in the turbines from the boiler.
Mining, Transportation, transmission losses. etc.
If thats what you are lalking about.
The coal is also wet you only get about 2/3 energy from it.
The further you transmit electricity the more energy is consumed by hysteresis losses.
Plus, producing electricity is like trying to blow up a balloon that is full of holes.
By linking several power grids together you get the following advantages:
1. Redundancy ... one or two generating plants can shut down and there is still adequate supply,
2. By linking all the grids together into a network you essentially make the average distance between the power plant and the consumer shorter. Eg. NYC gets a lot of power from New Jersey rather than upper New York state because it is closer.
