Renewable Energy Summary Renewable energy flows involve natural phenomena such as sunlight‚ wind‚ tides‚ plant growth (biomess) and geothermal heat. According to the International Energy Agency (2002)‚ “Renewable energy is derived from natural processes that are replenished constantly. In its various forms‚ it derives directly from sun‚ or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar‚ wind‚ ocean‚ hydropower‚ biomass‚ geothermal

“The energy for life comes from the sun.” Outline the role of the photosynthesis process to explain what is meant by this statement. (3 marks) chlorophyll 6CO2(g) + 6H2O(l) + energy C6 H12 O6 (aq) + 6O2(g) 2830 kJ glucose Photosynthesis is the process in which plants use the sun’s light energy to convert carbon dioxide and water into carbohydrates such as glucose‚ sucrose‚ starch and cellulose. Carbohydrates are high energy compounds

Alternative Energy Alternative Energy Alternative energy refers to energy sources that have no undesired consequences such for example fossil fuels‚ nuclear energy and falling water. Fossil fuels are coal‚ petroleum and natural gas. There are some characteristics of the fossil fuels that made the concept of alternative energy come into place. (Alternative Energy) One of the fossil fuels‚ Petroleum‚ forms a thin film around the grains of the rock where it formed. Pressure from the overlying rock

Energy is a very important factor that determines how far the cars I made for my project will go. This illustrates how if the car doesn’t have enough kinetic energy the car won’t go very far. According to my research‚ If work‚ which transfers energy‚ is done on an object by applying a net force‚ the object speeds up and thereby gains kinetic energy(Kinetic Energy) which will make

Energy is the fuel that runs the engine of the world economy. Believe it or not our need for energy is not primarily to run economies but intrinsically to create order in the world. Wind energy Wind energy is the kinetic energy associated with the movement of atmospheric air. It has been used for hundreds of years for sailing‚ grinding grain‚ and for irrigation. Wind energy systems convert this kinetic energy to more useful forms of power. Wind energy systems for irrigation and milling have been

General Papers 15 December 2014 Energy According to Mother Nature Network‚ green energy comes from natural sources such as sunlight‚ wind‚ rain‚ tides‚ plants‚ algae and geothermal heat. These energy resources are renewable‚ meaning they ’re naturally replenished. There are many different types of green energy such as wind energy‚ solar energy‚ and hydroelectric energy. Each type of energy is very diverse in the way it affects our society. “Last year‚ wind energy added nearly half of all new power

Energy Alternatives: * Alternative energy is any energy source that is an alternative to fossil fuel. In a general sense in contemporary society‚ alternative energy is that which is produced without the undesirable consequences of the burning of fossil fuels‚ such as high carbon dioxide emissions‚ which is considered to be the major contributing factor of global warming. * This chapter discussed only a few of the possible alternatives to our current combustible energy generation system
