The Energy Supply And Usage Of Renewable Energy - 10339 Words

Chapter 1: Introduction to Thesis Introduction to Thesis 1.1 Statement of the problem The world’s energy supply and usage harnessed by humans are predominantly occupied by fossil fuel combustion a non-renewable resource. On the other hand small fractions of the energy harnessed by humans are renewable resources at only about 13% of the total energy sourced. With fossil fuels emitting high amounts of greenhouse gasses that affect our climate negatively in the long term in addition to its non-renewability, alternative sources of energy supply particularly in the category of renewable energy can help alleviate the impact of the shortage of resources and the harmful impact of our energy usage on the environment. Salinity-gradient energy can potentially be a part of this alternate source of renewable energy as well as gas emission-free as it is based on the mixing of solutions with different salt concentrations through the uses of Osmotic pressure and a membrane. Salinity-gradient energy is applied through the application of pressure retarded osmosis (PRO) and its use for power generation has made it a viable pairing for desalination plants that use reverse osmosis/forward osmosis (FO/RO) in its processes. Salinity-gradient energy has only gained substantial attention in the last 10 years due to increasing cost of fossil fuels and because of its relatively new upbringing there is still a lot of research and understanding to be achieved. One of the major reasons for this beliefShow MoreRelatedEssay on Renewable Energy: The Switch is Now1504 Words   |  7 Pagesprevention of this future is renewable energy. Unfortunately the support for the use of renewable energy is weak and ineffective. Unless the US puts forth effort to research and promote the use of renewable energy to consumers, conversion from fossil fuels to renewable energy will no longer be an option. The use of fossil fuels on a large scale, specifically coal, began with the Industrial Revolution in England. Industries/corporations first used coal as a main source of energy to fuel their factoriesRead MoreAnalysis Of Renewables Or Bust And Its Effects On Our Health And Environment?1503 Words   |  7 PagesRenewables or Bust Many American cities have experienced the phenomenon of smog or haze at one point or another. This smog has led the general population, political leaders, and scientists to ask the question, â€Å"What produces this haze and what are the impacts on our health and environment?† (Fischetti). The average amount of energy consumed per person has dramatically increased over the past several hundred years (Christensen, 482). The prevalence of fossil fuel use in our world is a primaryRead MoreSolar Energy Incentives999 Words   |  4 Pagesthe progress of renewable energy across the United States of America. Strengthen national policies by introducing financial incentives for research, development, and manufacturing that tackle technical challenges to the growth of renewable energy. Incentives such as tax breaks, low interest rate loans, and grants will allow the renewable energy sector to implement cost-effective solutions and be and competitive against traditional energy sourc es.

The energy sources include both renewable and non-renewable resources and are the vital backbones of this modern world. The Industrial Revolution which took place in eighteenth century Great Britain acted as a sort of gateway to the discovery and usage of fossil fuels today (Industrial Revolution. Para 1). It was an increasingly developing time as the economic market tookRead MoreSolar Energy Industry Indi Problems And Prospects1092 Words   |  5 PagesTo meet demand-supply gap in the energy sector of India has led Government to tap solar energy that is sufficient to meet the annual demand of residential, agriculture and residential purposes. Solar energy sector is driven by demand and supply side factors, and it has the excellent chance to be World leader in this area if it tackles its challenges efficiently. Government can focus on establishing mini-grids to cater the needs of remote regions, implementation of renewable energy certificates, carbonRead MoreDevelopment Of Smart Grid Technologies1401 Words   |  6 Pagesself-governing and enhance the higher effectivity and efficiency of power deli very, and they also allow renewable energy recourses safely to connect into the grid to replenish the power supply from the normal customers’ distributed power plants and storage, power industries can minimize the cost to build more power plants with renewable energy, transmission lines, and substations to raise the level of power supply which to adapt to the modern electricity consumption. This memorandum can help people learn moreRead MoreEnergy: What is Micro Hydro Power1098 Words   |  4 PagesMicro hydro power is a concept that has over the years been adopted as an alternative energy supply for communities whose access to a national grid is limited by a factor or two. In fact, hydro power is one of the oldest sources of energy used by the human civilization. It has been used for hundreds of years to turn waterwheels for the purpose of sawing logs, grinding grains, and the manufacture of cloths. From the last century, large scale hydro power plants have been used mainl y for the generationRead MoreAlternative Energy Solutions For Renewable Energy1295 Words   |  6 Pagesdiminishing supply. We are scrambling for solutions in underdeveloped technology and overlooked industry. There is much debate on whether any alternative energy solutions are able to effectively replace fossil fuels. Even if they are, we are then faced with the problem of how renewable energy programs could be implemented and improved. There are many aspects of this debate to consider, including energy demand, financial support, and ecological factors. The push for alternative energies is essentialRead MoreEnergy Resources And Renewable Energy1240 Words   |  5 PagesEveryone uses a lot of power for lighting, heating, machines, movements, and so much more. All of that energy has to come from an energy supply. Some energy resources are renewable, while others are non-renewable. Energy has various forms and is a very essential part of our everyday lives. In my house, I always try to conserve energy when I can. I try an hot water by using a lower flow shower head and very rarely use the bath tub which does waste a lot of hot water. When buying light bulbs, I onlyRead MoreReplace Traditional Components Like Diesel Generators Essay1406 Words   |  6 Pagesare used to generate power in a microgrid with renewable energy sources for an Air-force field deployable hospital (AFFDH).
