NEW YORK Copper
demand will increase as the renewable energy sector expands,
according to the American Resources Policy Network (ARPN).
"Copper is the key to
renewable energy," ARPN president Daniel McGroarty said in a
statement. "Whether youre talking about electric
vehicles, wind or solar energy technology, youre talking
Copper has an
"integral role" to play in President Obamas climate
action plan announced June 25, McGroarty said. The plan aims to
cut carbon emissions further and focuses on reducing waste,
cutting down on coal, and boosting renewable energy projects,
such as the use of wind turbines, according to the White House
Every wind turbine
requires about 6,000 pounds of copper in the form of cable and
coil, according to ARPN.
Copper also is
critical to lower-emissions transportation, ARPN said. Electric
cars use double the amount of copper, mostly in wiring, than
standard cars, while buses, electric trolleys and subway cars
use an average of 2,000 pounds of copper each.
"Because copper is an
excellent conductor of electricity, it allows us to use energy
at a very high level of efficiency while minimizing
environmental impact," McGroarty said.
Ensuring a steady
supply of copper is critical to realizing the Presidents
climate action plan, according to McGroarty, who pointed out
that access to domestic copper resources in the United States
should increase. "We should be doing everything we can to
develop Americas copper resources in a responsible and
sustainable way," he said. "We can lessen our dependence on
foreign nations for the copper we need to transition to a
renewable energy economy."
change plan has not been welcomed by all metal sectors, though.
Steel and manufacturing interests maintain that the plan will
raise costs and hurt business (
