Sustainable development is the benefit that meet the needs of the people without compromising access to affordability, reliability, sustainability and modern quality of human satisfaction of its citizens within the limitation of the environment. It has become widely recognized that the rising environmental hazards, depletion threatened the unreliable supply of electricity with huge economic cost associated with fossil fuel has made renewable energy issue a significant sustainability resource as the basic requirements for development in developing countries. This paper aims to present review and promote access to harnessing, harvesting, storage, conversion and technology of renewable energy sources for generating electricity in developing nations by 2050. &nbsp;In this review, we have identified the various renewable energy sources, challenges and benefits. The recommendation on this investigation shows greatly our contributions to the aspiration of citizens in developing countries for alleviating struggles to overcome the epileptic power supply that has harassed the economy of the nation in jeopardy for long time.</p> T.

These gases trap heat waves as they approach the world and allow them to continue entering the atmosphere over time without being able to leave. This study used low global warming potential alternative refrigerants to reduce greenhouse gas emissions, in line with global efforts to phase out chlorinated fluids in order to preserve the ozone layer as a result of the Montreal Protocol. A software program called Cycle-D-Hx, which has a graphical user interface and a thermodynamic model of the refrigeration system, was used to evaluate how well household refrigerators working with various types of refrigerants performed. The model was validated using data from a household refrigerator charged with R134A. The performance of several low global warming potential alternative refrigerants, including R404A, R449A, R513A, and R452A, was then assessed using the model.</p> <p>The hydrofluoroolefin based R452A refrigerant is an alternative to R404A and R507 that is non-ozone depleting and has a low global warming potential. An azeotropic blend, R-513A is a drop-in replacement for R-134a in existing systems. Common hydrofluorocarbons and the new hydrofluoro-olefin molecule R1234yf are combined to form R449a, which is made up of R32 (24%), R125 (25%), R134a (26%), and R1234yf (25%). R513A, an aceotropic blend with no temperature glide, is composed of 44% R134a and 56% R1234yf.</p> <p>The simulation's findings demonstrate that R452A has a coefficient of performance 1.578, a zero potential for ozone depletion, a 0.5^oC temperature glide for the evaporator and condenser and also a low potential for global warming unit count of 2140. Along with these thermodynamic and environmental qualities, R452A blend can take the place of R134A as a refrigerant because it is non-flammable and noncorrosive and will not corrode the metal parts of the compressor and evaporator of the refrigeration system.</p> Adeyanju Anthony A.
