Energy Savings by Country

PROJECTED ENERGY SAVINGS USING Metglas®AMDTs

In the year 2010, it was estimated that total energy savings for the regions listed would amount to 81(TWh) of core loss reduction per year, or the equivalent of US $6.1 billion dollars annually. The reduction in the production of CO2, a major contributor to global warming, would be 47 million tons yearly.
