A change from one form of energy into another is called:

• Work

• Power

• Energy Transformation

• Conservation

What is efficiency?

• The total amount of energy lost
• The % of energy lost as heat
• The % of energy used to perform work.
• how long it takes for energy to be conserved

Energy is transferred to solar panels through the process of:
