An Analysis Of The Use Of Nanotechnology In Electrical Energy Production And Storage And As A Means Of Reducing Energy Consumption.

1944 words - 8 pages

The energy demand all over the world is expected to be 28 terawatts by 2050, which can lead to increase of energy consumption patterns and greenhouse gas production. (P.Alivisatos et al. 2005) One of the most significant issues the industrialised world is facing today is the energy challenge, issues associated with energy production, storage and reducing consumption of energy use. The use of energy has reason to rise over time due to an increase in the world population and the discovery of new technologies which require electrical energy. The electrical energy is used everywhere, from heating homes to manufacturing. The energy resources are divided into two types: alternative and traditional energy resources. The global energy challenge is primarily related to the limits of the traditional resources - major organic and mineral resources of our planet. For example, fossil fuels: coal, petroleum, oil and natural gas, whose use can damage the environment. In addition, due to their limited availability, they could one day run out. However, there is a possibility to use alternative energy resources, such as solar, wind, hydropower, geothermal and biofuel, which are renewable and do not harm our environment. A potential solution of energy crisis could be the use of nanotechnology, which can drive the exploration of a variety of alternative energy sources, from solar cells to hydrogen fuel cells to efficient batteries. Nanotechnology is the branch of engineering which studies objects measured by a nanometer – billionth of a meter. It is the collective term for a range of technologies, techniques and processes which involve manipulation of matter at the molecular and atomic levels. Nanotechnology materials are often not predictable from the laws of classical physics and chemistry. H.Vedam and W.Kong (2010) stated that “nanotechnology offers infinitive possibilities to develop innovative ways to efficiency capture, storage, and transfer energy and hence address both the short-term and long-term energy challenges”. The aim of this paper is to analyse the use of nanotechnology in alternative energy production, storage and as a means of reducing energy consumption.
Roger A.Hinriches and Merlin Kleinbach (2006) declared (claimed) that “every day the earth surface receives thousands of times more energy from the Sun than it consumed in all other resources”. Cleanliness, availability and renewability of solar energy make it virtually ideal. (Grant E.Gardner, 2008). The use of solar energy for production of electricity is based on the photoelectric effect. The photoelectric effect is a process, when light strikes certain metals and, as a result, electrons are emitted from the metal surface. (Hugh D.Young, Roger A.Freedman 2008). Photovoltaic cells (PV), known as solar cells, are devices which collect radiation energy in the form of sunlight and convert into electricity. Solar cells are made of semiconducting materials, especially silicon. Silicon absorbs...

The Use of Alternative Energy Essay

1718 words - 7 pages Our sources of oil or petroleum are running out. Although new oil deposits are being discovered every year, the amount does not equal to levels of our annual consumption. Petroleum also produces carbon dioxide, which contribute to greenhouse warming. In the effort to reduce the need for oil or petroleum as a source of energy many solutions are being discuss such as wind power, solar power, coal and the use biofuels such as ethanol as would be

Desert Winds And Electrical Energy Essay

804 words - 3 pages Desert Winds and Electrical Energy      The energy of the wind can be channeled into other forms of energy besides the energy used as an erosional agent. This is especially true of desert winds. Today, some desert wind is used to make electricity.      Wind velocity is affected by air temperature. When air warms and cools, it changes density, which creates air pressure differences that cause

Energy Storage

Energy consumption

1257 words - 5 pages readings -- consumption. Do we, as Americans, consume a great deal more than other developing nations do? The answer would be definitely. Do we consume too much? The answer to that question depends on whom you decide to ask. Sure, if I could modify one area in which I "consumed" too much for my liking, I would probably get rid of my $22,000 car in a heartbeat. Nevertheless, analyzing my own personal consumption was helpful and instrumental in opening
