Standing on the brink of the Fourth Industrial Revolution, we have to think about the future of energy demand. The question is- from what source will the future world supply energy?
We have to think about power generation. Because the people of the world have realized that, the civilization- that has been dependent mostly on oil, coal and gas for a long time is under threat of pollution caused by these substances. In today’s world, energy production depends on renewable energy such as oil, gas and coal for a long time.
The development of civilization began its journey by using these fuels. With the passage of civilization, great progress also made in science. People realize that the elements of energy that are being used extensively will one day run out from the earth. The world is moving very fast. Realizing this importance, scientists have been emphasizing the use of alternative energy for many years. The main source of energy is the sun. The main goal of human beings is to meet the energy needs by using the heat of the sun which is known as solar energy.
The use of solar energy is increasing all over the world gradually. Our country is not backward either. Solar panels are currently being used to generate electricity for everyday household uses. The fan is spinning, the TV is running and other electronics are also running using solar energy. Solar power has been used for a long time, especially in remote areas where it was difficult to get electricity once. These solar panels are a collection of numerous photovoltaic cells that convert the sun’s light energy into electrical energy.
As the population grows, so does the use of fossil fuels. As a result, significant resources like natural gas are almost at an end. The situation is the same in our country. Natural gas is an extensive source of energy used for factories, including power generation. Solar energy is the first choice as a sustainable alternative fuel. From which the human race will be able to produce energy for ages and will not be exhausted. The use of solar energy in various countries like America, China, Japan, Germany, and India is much advanced.
Today, houses are illuminating through the use of solar energy. Hat-bazaar is being lighted. Today electricity has reached all parts of Bangladesh.
The government has also extended electricity facilities to remote areas of the country. But when electricity did not reach those remote areas, those places were illuminated by solar power. Using solar power, it is possible to run not only houses but also small manufacturing factories.
According to a report of the World Bank, Bangladesh is ahead in the world in the expansion of solar power. The main problem in the world today is global warming. The most responsible for global warming is the use of fossil fuels such as coal. Researchers say that in the developed world, up to 10 per cent of the world’s electricity demand is being met by using renewable energy using wind and solar energy. This has reduced the use of fossil fuels. Scientists say the change in fuel consumption has also significantly reduced the rate of greenhouse gas emissions into the atmosphere.
Many countries in the developed world are now turning to use solar or wind energy instead of fossil fuels. At present, the contribution of solar power to the global growth of power generation is 70 per cent. The combined contribution of solar photovoltaic (PV) and wind to the global growth of power generation will reach 30 per cent by 2030. In 2019, this contribution was 6 percent. Utilizing solar energy, the government has undertaken projects like solar parks, solar mini grades and solar irrigation in different parts of the country. It is possible to meet a large part of the future energy by using solar energy.
The people of the world now want to protect the world from greenhouse gas. That is why the impact of greenhouse gases must be reduced. That will be possible if the industry runs on energy from renewable sources. Many countries are using solar energy to run buses as part of the test. Even if it is not widespread now, this effort will gradually lead to success. From the end of the twentieth century, other sources of renewable energy such as solar energy began to be used in Bangladesh. Before 2008, the number of solar home systems in the country was less than three lakh.
Due to several subsequent steps, the number of solar home systems in the country was 3 million in 2014 alone. According to the master plan for power generation taken in 2010, renewable energy will be 10 percent of the total power generation in 10 years. Bangladesh now ranks second in the world in the use of solar power at home.
According to a report by the International Renewable Energy Agency, a global organization in the renewable energy sector, Bangladesh ranks fifth in the world in terms of job creation in the solar sector. The world’s largest solar park is being built in Gujarat, India. The target has been set to generate 30,000 MW of solar power per year.
Every country is using solar energy to create electricity generation facilities that will ensure sustainable energy supply in the future. At the same time, the world will be as clean as before.
