Energy Conservation
 


 
Conserving Energy With Copper.
Copper It Means Saving Money AND the Planet
 
Energy prices are rising to their highest level in decades. There is great concern worldwide about climate change as greenhouse gas emissions continue to grow. Rarely has the importance of energy conservation been more apparent.

Copper - one of the most energy-efficient materials known - is at the forefront of efforts to conserve energy, save money, and reduce greenhouse emissions associated with global climate change.

Why copper? Because when compared to other conductors, copper's extremely high degree of electrical conductivity results in less generation of unwanted heat and more efficient power generation.

Engineers call this waste "resistive loss," and even give it a formula: I2R (current-squared times resistance) = heat. These losses result in vast energy waste leading to higher demands on generation capacity and increased emissions of greenhouse gases, like carbon dioxide.

Copper's superior conductivity is why most electrical and communications wire is made of copper. But copper's critical role in efficient energy use is not limited to wire and cable. All electronics and electric-powered equipment rely on the smooth and efficient operation of copper.

The information revolution that is transforming our world is powered by electricity and its future growth will depend on efficient energy use - including more copper.

To promote energy efficiency, the international copper industry has teamed with the US Energy Department, the European Union, and others to encourage the use of energy-efficient motor systems. These modern, high-efficiency motors save energy by using more copper in their windings. The motors can realize sizable energy and cost savings that pay for themselves many times over during their life-cycle.

And since electric motors are the single biggest industrial user of power, efficiency gains by using copper can have a big impact on reducing emissions and increasing productivity worldwide.

Motors are not alone in using energy more efficiently with copper. Transformers, busbars, and lighting ballasts all operate with lower power losses and less cost as the amount of copper built into these devices increases.

Consequently, a new energy-efficiency formula is pointing the way to the future: more copper = more efficient energy use = cost savings + reduced emissions.
