Web1 feb. 2010 · Generally, anti-icing techniques are more efficient than de-icing because less energy is needed — therefore, less chemical is used — to prevent a bond from forming than to break it. Anti-icing can be applied before a storm hits or early in the storm. Maintenance costs are lower, and there is a reduced environmental impact.
