A composite material or composition material or shortened to composite is a material made from two or more constituent materials; as a result, the new material is characterized with their different physical or chemical properties which are far away from the individual components. The primary used components remain separate and distinct within the finished structure, differentiating composite materials from mixtures and solid solutions.
Marine energy or marine power (also sometimes referred to as ocean energy, ocean power, or marine and hydrokinetic energy) refers to the energy carried by ocean waves, tides, salinity, and ocean temperature differences. The movement of water in the world¿s oceans creates a vast store of kinetic energy, or energy in motion. This energy can be harnessed to generate electricity to power homes, transport and industries. In this concern, the term marine energy encompasses both wave power i.e. power from surface waves, and tidal power i.e. obtained from the kinetic energy of large bodies of moving water. Offshore wind power is not a form of marine energy, as wind power is derived from the wind, even if the wind turbines are placed over water The marines have a tremendous amount of energy and are close to many if not most concentrated populations. Ocean energy has the potential of providing a substantial amount of new renewable energy around the world. Energy from the ocean is also known as hydro-electricity. The ocean can produce two types of energy: thermal energy from the sun's heat, and mechanical energy from the tides and waves.
The importance of the nuclear power industry to the nation¿s energy security is becoming increasingly clear. Nuclear energy is the only large-scale, carbon-free electricity source that the country can widely expand to produce large amounts of electricity. Noting that, nuclear power plants prevent the release of significant quantities of emissions that would be created by burning fossil fuels to generate the same amount of electricity. The current fleet of U.S. nuclear power plants eliminates the release of about 1 million short tons of nitrogen oxides and 2.7 million short tons of sulfur dioxide ¿ pollutants controlled under the Clean Air Act ¿ each year. They also prevent the emission of nearly 700 million metric tons of carbon dioxide each year; an amount nearly equal to that released from all U.S. passenger cars. The amount of nitrogen oxide emissions nuclear plants prevent annually is the equivalent of taking more than 47 million passenger cars off the road.
