Currently, the need for power consumption is important for the development of cities and industries. There are several traditional methods of obtaining power for the needs, but they pose a threat to environmental pollution. This is why we need to focus on alternative methods of obtaining power. Green energy can be considered an effective means of improving the amount of energy needed for industries, urban territories, and businesses without damaging the environment. Green energy is usually obtained from renewable energy technologies such as solar, wind, geothermal, and hydroelectric electricity. The best option for improving environmental sustainability and not negatively affecting the economic growth of the country is renewable energy. Notably, one of the primary aims 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. Therefore, green energy has achieved the goals of sustainability, i.e., they are the least costly, most effective means to increasing the sustainability of a nation's productive sector, the standard of living of people, 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 polluting it. This article focused on the benefits, necessity, and need of green technology for a brighter future.
