英検1級2次試験:Is the solar power the energy of the future?

Is the solar power the energy of the future?

(太陽光発電は未来のエネルギーか?)

 

I don't think that the solar power will be the energy of the future. I have two reasons to support my opinion.

 

First, solar power doesn't have capacities to produce large amount of electricity. Some may argue that the energy density of solar power is becoming higher and higher. However, in fact, energy output of other forms of power generation such as nuclear power is much higher. In order to provide citizens with sufficient electricity, using a combination of solar power and other forms of power plant is necessary in the future.

 

Second viewpoint is weather condition. The amounts of electricity created by solar power is basically dependent on sunlight. Also, the number of sunny days is very different according to seasons. Plus, the amounts of sunlight vary depending on region. These factors make the amounts of electricity unstable, which diminish the quality of life.

 

Considering these, I believe that replacing fossil fuels or nuclear power plants with solar power is very difficult. (163 words)
