IELTS Academic Writing task 2 - Solar energy

The utilization of energy, nowadays, has increased significantly as the world’s population and industrialization has risen. Oil and charcoal as the main resources of energy are in a critical condition now and the usage of it should be controlled at its best to keep its storage stable. In order to do so, experts and researches have been developing the new alternative energies which can be used to support some kinds of activities. Solar energy is one of the alternative energies that will be explained in three main parts, which are its definition, production process and advantages and disadvantages. 

Solar energy is energy generated from sun’s heat and radiant light using sophisticated technologies such as solar heating, photovoltaic, solar thermal energy, solar architecture and artificial photosynthesis. Such technologies facilitate the process of converting sun’s energy into thermal or electrical energy. It is the cleanest and most abundant renewable energy source available especially in equator-line-near region. Moreover, it is a high appealing source of electricity as it has large magnitude of available energy. Besides, solar energy known as a flexible energy and its plants can be built as utility-scale solar power plant. Some of plants can be used to store the generated energy after the sun sets.

Energy based oil is the highest uses. It becomes a problem which is no guarantee of oil resource. Therefore, solar energy is good alternative to fix the problems. To produce solar energy is simple and environmentally friendly which is sun as basic energy, and people use the glasses to collect the light of sun, and it enters to concern in one line or one point. Also, it produces hot steam. The high of hot steam is using to be going on the turbine where it is producing the electrical energy.

Solar energy has both advantages and disadvantages. The advantages of solar energy are compared with other energy; the first, the energy can be directly produced and constantly available until the end of the world; the second, it cannot be mixed with other energy because the sun shines directly to the world without a barrier except the cloud; the third, the solar energy is obtained from the sun without the cost. Besides, the solar energy has disadvantages which are still depending with the weather conditions. For instance, if the weather conditions do not support to obtain the energy, it cannot be got directly.

To sum up, some researches develop solar energy which is one of the alternative energies to solve the problem that humans face in the world, and there are some drawbacks as well as benefits.
