Which solar technology is used in most residential and commercial solar installations?
-
Crystalline silicon
-
Thin-film
-
Concentrated solar power (CSP)
-
Organic solar cells
A
Correct answer
Explanation

What is the future of solar energy?
-
It will become the dominant source of electricity
-
It will continue to grow, but will not become the dominant source of electricity
-
It will decline in importance
-
It is uncertain
B
Correct answer
Explanation
Solar energy is expected to continue to grow in importance in the coming years, but it is unlikely to become the dominant source of electricity. Solar energy is a clean and sustainable source of energy, but it is intermittent and can be expensive. As a result, it is likely to play a complementary role to other sources of electricity, such as wind and nuclear power.
What is the term used to describe the transfer of energy from the Sun to the Earth's magnetosphere?
-
Solar Wind
-
Solar Flares
-
Coronal Mass Ejections
-
Geomagnetic Storms
A
Correct answer
Explanation
The solar wind is a stream of charged particles that continuously flows from the Sun's corona and interacts with the Earth's magnetosphere.
