In the era of development, metropolitan cities are developed with a rapid pace becomes a center point for the industries, trade, administration, education, and technology. Cities are very different from villages in terms of shape and density of population, business structure, number of houses, livelihood and in administration facility. Modern ecologist gives the name as an artificial ecosystem. Currently, cities are very good in the view of modern facility and employment. But because of huge and rapid expansion of cities generates different problems.
In last 50 years, urbanization process in the world becomes very rapidly. In 1960, 33% population of the world lives in an urban area which increases, in 1975 it becomes 38 %, in 2001 it becomes 46 % and in 2014 it becomes 54%.
Thus the centralization of a population in cities makes causes of many problems. These problems are related to space and enough residence, transportation, water supply, health, education, enough supply of electricity and pollution.
Without electricity modern cities like a dead city. In the city for every work either it is domestic work or industrial has need of electricity. Due to increase in urban population need of electricity increasing day by day. Many plants of electricity are being developed but there is a lack of enough supply of electricity.
Ways to produce enough electricity-
Solar Power-
This is one of the most efficient energy plants. Because once we buy solar panel then it is for many years. We do have to pay any electricity cost after that. Solar power adoption is increasing now. Now in many countries, it is used as an electricity source.
Wind Power-
This is also a source of energy. This is mostly used in the areas where wind speed is more. Mostly in sea areas, it is used. Sometimes in hill areas we can also see this technology for source of power.
Garbage Power-
Garbage is mostly generated by the human. As we know every day we throw some garbage in the dustbin. Where the population is more the collection of garbage in huge amount. In this process, we use garbage to produce energy. This is a good way because the collection of garbage is the everyday process. We can utilize that garbage for our energy source.
