Harnessing Solar Energy Power Quiz! Trivia

1.

Enough sunlight falls on the earth every hour to meet the world’s energy demands for _______ years.
- A.
  
  1
- B.
  
  2
- C.
  
  3
Correct Answer
A. 1

Explanation
Enough sunlight falls on the earth every hour to meet the world's energy demands for 1 year. This implies that the amount of energy received from sunlight in just one hour is sufficient to fulfill the energy needs of the entire world for a year. This highlights the immense potential of solar energy as a renewable and sustainable source of power.

Solar energy is not necessary because we have all the fossil fuels we need can last us for ______________ years.
- A.
  
  75
- B.
  
  7 billion
- C.
  
  Forever
Correct Answer
A. 75

Explanation
The correct answer is 75. This suggests that solar energy is not necessary because we have enough fossil fuels to last us for 75 years. This implies that the availability of fossil fuels is limited and will eventually run out, which is why solar energy is not necessary in the long term.

Energy from the sun reaches the earth in the form of_______________
- A.
  
  Futons
- B.
  
  Photons
- C.
  
  Phantoms
Correct Answer
B. Photons

Explanation
Energy from the sun reaches the earth in the form of photons. Photons are particles of light that carry energy. They are emitted by the sun and travel through space to reach the earth. These photons are responsible for providing heat and light energy to our planet.

Solar energy is a desirable alternative to fossil fuels and other depletable resources because _____________
- A.
  
  It reduces pollution- and noise-free
- B.
  
  It is often require moveable parts
- C.
  
  The sun is an inexhaustible resource
Correct Answer
A. It reduces pollution- and noise-free

Explanation
Solar energy is a desirable alternative to fossil fuels and other depletable resources because it reduces pollution and is noise-free. Unlike fossil fuels, solar energy does not release harmful pollutants into the atmosphere, contributing to cleaner air and reducing the negative impact on the environment. Additionally, solar energy systems operate silently, eliminating the noise pollution associated with traditional energy sources. Therefore, solar energy provides a sustainable and environmentally friendly solution for meeting our energy needs.

5.

Solar energy is not necessary because we have all the fossil fuels we need
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Solar energy is necessary despite the availability of fossil fuels because it is a clean and renewable source of energy. Fossil fuels are finite resources that contribute to pollution and climate change when burned. In contrast, solar energy is abundant and does not release harmful emissions. Additionally, investing in solar energy can lead to energy independence, reduced energy costs, and job creation in the renewable energy sector. Therefore, the statement that solar energy is not necessary due to the availability of fossil fuels is false.

6.

Is converting solar energy to electricity-free?
- A.
  
  Yes
- B.
  
  No
Correct Answer
A. Yes

Explanation
Converting solar energy to electricity is not free. While sunlight is a free and renewable resource, the equipment and technology required to convert solar energy into electricity, such as solar panels and inverters, come with a cost. Additionally, there are installation and maintenance expenses associated with solar energy systems. Therefore, although solar energy itself is free, the process of converting it into electricity involves costs.

7.

Using more solar panels will allow us to save our environment.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Using more solar panels can help us save the environment because solar energy is a renewable and clean source of energy. Unlike fossil fuels, solar energy does not produce harmful emissions or contribute to air pollution, reducing the negative impact on the environment. Additionally, solar panels do not require large-scale mining or drilling operations, further minimizing damage to ecosystems. By utilizing more solar panels, we can decrease our reliance on fossil fuels and work towards a more sustainable future.

8.

In two years a solar panel will generate the same amount of energy as was needed for its manufacture.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
This statement suggests that the energy generated by a solar panel over a span of two years will be equivalent to the energy consumed during its manufacturing process. This implies that the energy payback period for the solar panel is two years, which is a commonly used metric to assess the environmental impact and sustainability of renewable energy technologies.

Rate this question:
9.

By installing solar panels in less than 10% of the desert surfaces of the Earth, we would produce enough electricity to supply the entire world's electricity consumption for an entire year.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Installing solar panels in less than 10% of the desert surfaces of the Earth would generate enough electricity to meet the global electricity consumption for a year. This suggests that solar energy has immense potential and could be a viable solution to meet the world's energy needs.
