WAVE ENERGY Chapter 2: Energy Technology 2.1 Source of Wave Energy Ocean waves are caused by the wind as it blows across the open expanse of water‚ the gravitational pull from the sun and moon‚ and changes in atmospheric pressure‚ earthquakes etc. Waves created by the wind are the most common waves and the waves relevant for most wave energy technology. Wave energy conversion takes advantage of the ocean waves caused primarily by the interaction of winds with the ocean surface. Wave energy is an

using renewable energy to replace fossil fuel. In addition‚ renewable energy is generated by natural resources such as sunlight‚ wind and biomass which produce less or no pollution when generate energy. Furthermore‚ renewable energy will be demanded for approximately half of the worldwide electricity supplies to reduce CO2 emissions by 2050‚ which it is estimated by The International Energy Agency (Cited in Shi 2010). This essay will focus on two forms of renewable energies which are solar

Energy Transformation Conduction‚ convection‚ and radiation are things that exist in our life. Thanks to that stuff we have things like electricity and things to cook too. I am going to explain things about energy transformation. Heat transfer is the way heat moves through matter to change the temperature of other objects. There are three types of heat transfers‚ Conduction‚ Convection‚ and Radiation. The first kind of heat transfer‚ conduction‚ is heat transferring through direct contact of materials

Energy Resources and their Uses in Producing Electricity Renewable energy is energy drawn from natural processes that are restored quicker than they are used up‚ some renewable energy resources are biomass‚ food‚ wind‚ waves‚ flowing water‚ solar and geothermal. The sun however‚ is known to be the ultimate energy resource since almost all energy resources originate from the sun’s energy. This is possible according to the law of conservation of energy which states that energy can’t be destroyed
