Global energy demand is expected to reach 28 terawatts by 2050, which could lead to an increase in energy consumption patterns and production of greenhouse gases. (P. Alivisatos et al. 2005) One of the most important problems facing the industrialized world today is the energy challenge, the problems associated with energy production, storage and reduction of consumption of energy. Energy consumption tends to increase over time due to the increase in the world's population and the discovery of new technologies that require electrical energy. Electric power is used everywhere, from heating homes to manufacturing. Energy resources are divided into two types: alternative and traditional energy resources. The global energy challenge is above all linked to the limits of traditional resources, the main organic and mineral resources of our planet. For example, fossil fuels: coal, oil, petroleum and natural gas, the use of which can harm the environment. Additionally, due to their limited availability, they may one day be sold out. There is, however, the possibility of using alternative energy resources, such as solar, wind, hydroelectric, geothermal and biofuels, which are renewable and do not harm our environment. One potential solution to the energy crisis could be the use of nanotechnology, which could spur exploration of a variety of alternative energy sources, from solar cells to hydrogen fuel cells to efficient batteries. Nanotechnology is the branch of engineering that studies objects measured to the nanometer, or one billionth of a meter. It is the collective term for a range of technologies, techniques and processes involving the manipulation of matter at the molecular and atomic levels. Nanotechnology materials are often not predictable from middle of paper......011)6) W. Luther. 2008.
