It is a big difference to make snow with old and new snow canons. With old technology, it may be ten times as expensive as with a modern automatic snow cannon systems.

UPDATED
It notes energy consultant, Hanna Andersson, who did his thesis on the energy efficiency of snow last winter.

Then he studied at Faculty of Engineering LTH. Now he is the energy consultant at Eco Perspectives in Linkoping and an expert on just snow. Today, almost all ski resorts in Sweden on "artificial" snow.

There are only a few sites in northern Sweden as completely confident that it appears enough natural snow.

- If the snow cannon the development and creation would not have been made by it would ski tourist industry in Sweden and the world is not looking like it does today, "says Hanna Andersson for New Technologies.

To save money on electricity price rise
With rising electricity prices, it has become increasingly important for ski facilities to have a thoughtful approach to the snow and a good knowledge of how to make snow in an efficient manner.

ImageThe difference in energy expended to produce 0.3 cubic meters of snow - that is, 30 centimeters of snow on a square meter surface area - can vary between 0.25 kWh and 2.8 kWh depending on systems and how it is structured, according to Hanna Andersson calculations.

He argues that modern, automated systems for snow are much more efficient than manually driven snow. There is a difference of 30-50 in efficiency.

The compressed air draws energy
The bulk of energy is used to compress the air to squeeze out the water through the nozzle and turn the snow drops of water to snow.

- At a temperature of -5 degrees consume snow cannon of the old model, approximately 400 liters of air per second and about 5 gallons of water per second. A newly developed snow canons consumes only 10 liters of air and 2 liters of water. The older the gun, therefore, consumes 40 times more air and 2.5 times more water, "says Hanna Andersson.

But it's not just the technology of snow affecting the cost of snow.

- It is important that the snow is produced at the right temperature, in the right place, in light winds and can not produce more snow than is necessary. " Says Hanna Andersson.
