In a typical power distribution grid, electric transformer power loss typically contributes to about 40-50% of the total transmission and distribution loss. Energy efficient transformers are therefore an important means to reduce transmission and distribution loss.^[1] With the improvement of electrical steel (silicon steel) properties, the losses of a transformer in 2010 can be half that of a similar transformer in the 1970s.^{[citation needed]} With new magnetic materials, it is possible to achieve even higher efficiency. The amorphous metal transformer is a modern example.^[2]
