34 WEATHERWISE JULY / AUGUST 2008 s the debate over the need for renewable energy heats
 

Summary: 34 WEATHERWISE JULY / AUGUST 2008
s the debate over the need for renewable energy heats
up in meeting rooms, legislatures, and boardrooms
across the globe, the ultimate renewable energy
source is blowing all around us. On average, there is
enough power from the wind to meet the world's electricity needs
35 times over. Today, as the cost of a barrel of oil soars and global
warming has us searching for clean, renewable sources of energy,
policymakers and scientists around the world are working to make
the idea of gleaning electrical power from the wind on a larger
scale a new reality. The goal of drawing 20 percent of all generated
electricity from the wind once seemed pie-in-the-sky, but it has
been realized in Denmark and is a realistic goal in other parts of
the world, such as Spain and Germany. In the United States, wind
currently provides less than 2 percent of the electricity demand.
But in several states, such as California, plans exist to reach the
target of generating 20 percent of energy from renewable sources,
including wind, by 2010 and 33 percent by 2020.
