Global energy: From Conventional to alternatives

There exist a wide range of possibilities about the future of energy in connection with the plethora of things to cope with in today’s description of energy shortcomings. As the most considered ill in global talks continually emphasize the more need for clean energy source fulfilling the goal of sustainability,it becomes clear that the world is navigating the next curve opening and giving room to Individuals and Scientist alike,Corporations and Non For Profit, States and Multi-lateral platforms to create and accomodate change. The protection of structures already created by today’s energy needs as well stand threatened by the continuos gravity of change. This curve is in several ways expected to redraw the unequal scale of energy control doling the same number of playing cards to all party. It stresses the need to find sources that will fulfill the clean template set by The International Community and Regional Bodies. The transition from conventional to alternative would thrive on the wings of ubiquity locking out the thought of energy resource as a tool of threat evidently used by Arab oil producing states in 1973 which effect made oil prices quadriple and set the mark for the continuos energy crisis which ripple on Global Economy. Exploring alternatives will reduces the pressure mounted by cartel and provide entree for new structure to be established. Coal is found in specific places based on the geological compass and fossil formation; oil in gulfs,delta and rich basins while nuclear energy is derived through enriched uranium found in few places globally. First in the list of alternatives is the power of the sea posing the question: Could sea power solve the energy crisis? It may sound like a science fiction,but Ocean Thermal Energy Conversion (OTEC) offers much. The system extract and uses the sea as a giant solar-energy collector. The simplicity of this model draws energy from the difference in temperature between the surface of the sea (up to 29C in the tropics ) and the waters a kilometre down which is typically a chilly 5C. This powers a “heat engine”,think of the refrigerator in reverse in which temperature difference creates electricity. This idea is attached to French inventor, Georges Claude who is well remembered for the creation of the neon lamp. This technology operates a ‘closed cycle” that uses warm water to heat ammonia which boils at a low temperature.This expand into vapour driving a turbine that produces electricity. Cold water from the depth is used to cool the ammonia returning it to the cool state so the process can start again. It also has an ‘open cycle” version which boil warm seawater in a vaacum chamber leaving behind the salt content and generating stem to turn a turbine. The energy projected to be generated will rival the output of a typical nuclear power station with no thought on the regular waste treatment or astronomical decommissioning cost of a nuclear facility. Toiling this pathway has ernomous hope to put an end to drought in patched region as the process through its open cycle can produce vast quantity of desalinated water estimated at 1.2million litre for every megawatt of energy. OTEC has gone through series of testing validating its power to come to the rescue.This and much more we will explore in our next read to see the future of energy secured by the power of the sea.
