A Comparative Study on Renewable Energy Sources

The green energy sources especially solar, wind, biomass and geothermal has become predominant systems which push the whole world towards more technology added to its installing phase every day. Since the time their recognition as an indispensible part in global sustainable steps that is moving toward new era of modernized usages. As the world struggles to balance energy security and climate change, greener generation solutions have become a financially friendly way of reducing greenhouse gas emissions, while also decreasing dependence on fossil fuels. This manuscript sought at the technological advancement and economic benefits, policy initiative that is driving faster growth of renewable based power supply globally. This will be followed by the challenge of how to integrate these energy sources in existing electricity grid systems, job creation potential and use for achieving national commitments on sustainable development goals. The larger demand for renewable energy solutions is becoming globally and there comes a need to know the positive and negative sides of the source. Solar and onshore wind boasts have the greatest potential because of their scalability and ever-cheaper costs. But it is hampered by intermittency barriers. Geothermal is another type of base load power that reliability provides constant energy but only available in certain geographical location. While hydro leaves great scar on ecological system. Bioenergy, if produced sustainably causing minimal emissions and without competing for land use. The research is meant to analyse and illustrate that while none of the single renewable energy resources could satisfy dedicated segment in terms of energy demand. A sophisticated set up for these can be developed which together with technological advancements and strong policies may substantially contribute towards achieving stable as well as safe future vision on the use of sustainable energies.
