Even till today, there are villages and remote areas where electricity still hasn't reached. How do these people survive? With hurricanes or lanterns there life goes on a daily basis. However still they have to purchase oil for the lanterns. There was no substitute until now. Remote villages people are surviving or farmers are going on in the old ways of burning firewood or lanterns which has been part of Bangladeshi heritage. Taking electricity to such regions is more costly and expensive and some places may require heavy digging and construction. The lines also have to be made secured. This means more construction, means more budget which will bring us to bankruptcy and deficit. It is not possible to do such construction for a country like Bangladesh; this is why we need alternative energy. We cannot wait, we need fast and diligent, research, innovation and for the betterment of greater cause, which is for Bangladesh.
Although there are several new energy sources that we can evaluate that will be most suitable for Bangladesh, however the most effective and easy and abundance is the solar energy for the sun will provide the entire natural source. To know how solar energy works and functions, we must look at the definition of solar and how it works. Solar power in simple terms is the sunlight that we all have known and have existed for centuries and decades. The sunlight from the outer surface of our planet earth which transmits through the suns ray or light is solar power. According to the estimation of scientists and scholars it has been said, one hour of solar power on earth can meet the energy demand of the world for one year. Solar power can be used as energy source. The simple example of solar power working are dying a damp cloth in the sun and heating a bucket of water under the sunlight. In the water the damp cloth gets evaporated and the cloth becomes dry. In the case of water in the bucket, the heat is absorbed by the water particles resulting in the increase in temperature of the water.
It is high time for people of Asia especially South and South East Asia to change and work to change the energy crisis we have been facing for decades. The energy is costly not only in human factor, but in economic growth and self development of our nations. Although we may not sincerely look at the global warming and all other effects that is happening in our solar systems since it does not affect us directly, but we should know that it affects us every bit. The air we breathe, the amount of air being exhaled from the fumes, also from toxins, commercial properties, and industrial complexes it all effects us. With the ever-changing time with evolution, our water ways are becoming slowly polluted, where we are unable to receive all water source and supply to general demand. In same process power plants that used to run on hydro or water for long time and with the increase of demand due to population increase supply has become scarce as we see every day no matter where a person lives in Dhaka or other cities and towns of Bangladesh.
