Review of Renewable Energy Role in the Development of the World

Abstract

The study was carried out since 16, September, 2020. The study major objective was to review the renewable energy role in the development of the world. Total 17 articles were downloaded from the net and read in depth and analyzed the situation. The study indicates that renewable energy is that energy which never finish and it infinitely provide energy to community of the world. The example is the solar, water and wind energies. Renewable energy is the clean energy and it does not add any carbon to atmosphere. Now a day majority world countries try to identify the renewable energy in the world for running the daily system for improving the socioeconomic condition of the world. The study further explained that fossils coverage for supply energy in the world is still 60% which is the main cause of CO2 emission to atmosphere while the share of renewable energies and other energies is only 40% but now the trend of the solar and wind energy production in the world is annually increasing. China and USA now a day highly focus on renewable energy. Large number of projects is working for renewable energies in the world. Germany, Japan and UK through wind produced huge electricity in the world while in Pakistan large number of hydropower working for electricity production. Both renewable and non renewable energies have plus and minus in the world. The Water dams produce electricity which is the major source of renewable energy in the south Asian world but when dams are constructed it create problems for animals and community which disturb the ecosystem of the world. Similarly wind electricity production system kills many birds in the world while geothermal projects increase the earth quick in different country of the world. So on one side it has the benefits for the world but on the other side it has disadvantages to the community of the world. Many conferences have been held in the world for controlling the global warming which is the causes of the emission of CO2 to the atmosphere by non renewable energy in the world. The CO2 create the global warming and increase the world temperature. Since, in 2014 the increase of temperature in the world was 0.85 degree centigrade. The increase of temperature disturb the climate of the world which in the long run change the pattern of the cropping and multiply the diseases while also disturb rainfall trend and bring the flood and melt the glacier on the top of the hill which further disturb the old people health, social life and livelihood of the community in the world. On the basis of problems the study recommend that to increase the renewable energy sources consumption in the world.; Family growth should be controlled for more population pressure on the world resources; Sustainable methodology for development purpose should be applied for escaping the life of the future generation for renewable energy increasing in the world; Mostly focus on solar and wind energy utilization in the world for escaping of CO2 emission to atmosphere; Oil, natural gases and coal consumption should be decreased for emission of CO2 gases for provision of clean environment; Not make large dams for production of energy of electricity while short dam should be constructed for escaping of ecosystem for world community. Sometime dams are made which damage the ecosystem of the community and disturbs the life of animal and crops in the area; New innovation should be developed for enhancing renewable energy in the world.
