Very - probably well over 90%. An electric kettle is very efficient, especially if the body is made from plastic rather than metal; almost all of the electrical energy used goes into heating the contents rather than the container. A metal bodied kettle used on a gas stove would be significantly less efficient.
the eletric kettle may prove to be a little more efficient on the basis that when the water has fully boiled it switches itself off.
The kettle will be less efficient because it won't be benefitting from the effects of convection currents. It will use considerably more energy.
A Ghillie Kettle, Kelly Kettle, or Eydon Storm Kettle are all the same basic product. They are available from their websites: http://www.ghillie-kettle.co.uk/index.html http://www.kellykettle.com/ http://www.eydonkettle.com/ A slightly different version from New Zealand called a Thermette is available in copper from: http://www.thermette.com/ They are all very fuel efficient and will work well in windy/wet weather.
There are many factors that affect the loss of energy:1 the resistance of the wire2 the kettle will keep most heat in but not all heat within the kettle so more energy is lost3 the water will evaporate out the top and that is also a cause. (they can't close it off otherwise the pressure would build and it would explode).
First of all, there are many different types of kettles sold and some kettles function differently from others. Traditionally a kettle will know when to release steam due to the kinetic energy/movement of steam, within the kettle. It will then release the steam so that it is not trapped inside. However, there is also a different type of way of how a kettle will know when to release steam. Nowadays, this method is becoming more popular with newer kettles. A kettle will release steam once the kettle reaches a certain temperature and this is due to the heat energy of the kettle. Heat causes steam and so these newer kettles will still be able to release amounts of steam. Some people say that they prefer the method of the heat energy of the kettle instead of the movement of the steam and that it is much more efficient. Ultimately, a kettle will know when to release steam, either by the kinetic energy of the steam inside the kettle, or by the heat energy of the kettle.
