Worked Solution & Example Answer:The photograph shows a solar array in Germany which produces electricity equivalent to the power output of 20 nuclear reactors working at full capacity - Junior Cycle Science - Question a - 2013
Step 1
By what method of energy transfer does the sun’s energy get to the solar array?
Answer
The sun’s energy reaches the solar array primarily through the method of radiation. This is a process where energy is transferred in the form of electromagnetic waves, allowing solar panels to absorb sunlight and convert it into electrical energy.
Step 2
Compare, giving a reason, the safety of the solar array with the safety of 20 nuclear reactors.
Answer
The solar array is significantly safer than the operation of 20 nuclear reactors. The primary reason is that solar power generation poses no risk of pollution or radioactive material release, unlike nuclear reactors which can result in serious safety issues. Nuclear reactors could become unstable, leading to potential meltdown or explosion, which poses substantial risks to the environment and public safety.
