WITH THE NORTH AMERICAN RENEWABLE ENERGY INDUSTRY
in wind-generated power, the number of wind farms and the costs involved in constructing
them is increasing exponentially. he global wind power market is estimated to be worth
$60 billion annually, with the United States being the world leader in terms of installed
capacity.
As a form of renewable energy that lessens North America’s historical reliance on fossil
fuels and reduces carbon emissions drastically each year, the technology used to generate
wind power is indispensable. However, as with any technology, there are safety issues
that need to be addressed. Turbine manufacturers and wind farm operators, as well as the
general public, are becoming increasingly aware of the issues speciically related to ire
safety.
