Q. Consider the following statements regarding the potential application of copper
1. Copper is an excellent conductor of thermal and electrical energy
2. Copper can be recycled completely many times over without any loss in performance.
3. Copper cannot be used in renewable energy systems to generate power
Which of the above statements is/are correct?

[A] 1 and 2 only

[B] 2 and 3 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: A
Notes:
  • Copper is an excellent conductor of thermal and electrical energy; the power systems that utilise copper generate and transmit energy with high efficiency and with minimum environmental impacts. The use of copper in energy systems helps reduce carbon dioxide emissions. 
  • It can also be recycled completely many times over without any loss in performance. 
  • Copper is a highly efficient mineral used in renewable energy systems to generate power from solar, hydroelectric, thermal and wind energy.
