15. Key trend Glass fiber composites are now
lower first cost than stainless steel
Increasing demand and extraction costs for Nickel
and Chrome have increased stainless steel costs.
This trend is forecast to continue. For many
applications composites are now a lower first cost.
Composites, with 1.2MM tons used annually (800kt
of glass fiber) in the corrosion market, still only
compose 0.2% of total corrosion materials market.

18. Key Trend: Wind power forecast to be 12% of
global electricity production by 2050 *1 at which
time over 2,000 GW of installed wind capacity will
annually avoid the emission of up to 2.8 gigatons
of CO2.*1
•US Wind Market Positioned for strong near terms growth*2
•Efforts to secure PTC eligibility in 2013 resulted in 13GW under
construction and 11.5GW in order intake from Jan 13 to Feb 14
•A potential tax extenders package that include a PTC extension
would create upside to the n16GW forecast from 2014 to 2016.
