RENEWABLE ENERGY Paragraph For All class

 Hello, how are you students? Regular posts will be made again after many days. However, the paragraph I will discuss today is renewable energy. Today, gas is used in large quantities all over the world, which is very expensive to make artificially. The questions discussed in today's paragraph are given below:

(a) Which energies do the countries of the world rely on?

 (b) What types of energy sources are

these? 

(c) What problems are created due to the reliance on non-renewable sources? 

(d) What is the solution to the crisis of energy sources?

 (e) What are the other forms of renewable energies?

(f) What are the duties and responsibilities of the countries to solve the energy crisis?

  RENEWABLE ENERGY (নবায়নযােগ্য শক্তি)

The energy sources have always been a major factor of change throughout history. Now the countries of the world rely heavily on petroleum, coal and natural gas for their energy sources. There are two types of energy sources such as renewable and non-renewable. Hydrocarbon or fossil fuels are non-renewable sources of energy. Reliance on them creates real major problems. First, fossil fuels such as oil, coal, gas, etc. are finite energy sources and the world eventually will run out of them. Secondly, they will become too expensive in the coming decades and too damaging for the environment to repair. 

Thirdly, fossil fuels have direct polluting impacts on earth's environment causing global warming. Besides, the era of wood and biomass has almost come to an end. The age of oil and natural gas would soon be over within the next few decades. So, the only solution is that mankind can look for the massive use of solar energy in future. The sun's heat drives the wind and this wind energy can be captured with wind turbines to produce electricity. Then the wind and the sun's heat cause water to evaporate. When this water vapour turns into rain or snow and flows downhill into rivers or streams, its energy can be captured as hydroelectric energy. Scientists have identified hydrogen as another form of renewable energy source.

 Besides, ocean energy comes from several sources. Ocean's force of tide and wave can be used to produce energy. So, it is high time the developing or developed countries took essential initiatives tapping alternative energy sources mainly known as green or renewable energy sources.
