Read a text about solar energy. Circle the letter A, B, C or D to indicate the best answer to each of the questions.

It is true that the sun plays an important part on Earth, and people have always tried to make use of its energy, but in 2020, solar energy accounted for less than 9 percent of the world's energy consumption. Why isn't solar energy popular today despite its benefits?

Solar energy is truly more beneficial than many other sources of energy. First, it is renewable and easier to exploit than fossil fuels, such as coal or oil. Next, the solar energy generates minimal greenhouse gas emissions, so solar energy is cleaner and safer for the environment. Moreover, solar source is abundant and produces a huge amount of energy. According to the US Department of Energy (DOE), with an hour and a half of sunlight that reaches the earth, it is possible to produce enough power for all human's need for an entire year. More importantly, solar technologies are getting more efficient, which improves the quality of solar panels. It is promising that a solar panel can be used for over three decades and its battery storage system will greatly improve. This also means that in the long run, solar energy will be cheaper than other sources of energy.

On the other hand, solar energy has some drawbacks. Today's prices of solar panels are too high for many households to obtain. However, thanks to the development of technology, the costs have been slowly but consistently decreasing. One more problem is that this source of energy is not always available in countries that receive limited sunlight throughout the year. In this case, alternative resources like geothermal energy and hydropower can be better options.
