Currently, the need for power consumption is important to develop cities and industries. There are numerous traditional methods of receiving power for needs, but they are threats to environmental pollution. This is why we need to focus on alternative methods of receiving power. Green energy can be considered an effective means of promoting the amount of energy needed for industries, urban territories, and businesses without damaging the environment. Green energy is typically derived from renewable energy technologies such as solar, wind, geothermal, and hydroelectric electricity. The best option for improving environmental sustainability and having no negative effects on the nation's economic growth is renewable energy. Notably, one of the primaries aim of sustainable growth is to assure the availability of energy sources for future generations while spending as little money and emitting as little pollution as feasible. Green energy has, therefore, attained the aims of sustainability, i.e., they are the least costly, most effective means to increase the sustainability of a nation's productive sector, people's standard of life, and the environment. The main focus of this work is the production, utilization, and implementation of green energy sources globally. We are alone responsible for saving the planet from extinction because we are the ones who pollute it. The article primarily focuses on the advantages, necessity, and need for green technology for a brighter future.
