BURNING FUELS Fossil fuels can be used to make electricity in a power plant. They are burned to heat water into steam‚ which can push a fan-like object called a turbine. When the turbine turns around‚ magnets in it make electricity. Fossil fuels are fuels formed by natural processes such as anaerobic decomposition of buried dead organisms. The fossil fuels are coal‚ oil and natural gas. They are fuels because they release heat energy when they are burned. They are fossil fuels because they

Fossil fuels have been the main component used to get the source of energy for decades around the world where relying on the use of it has became a way of life. Kristinstand in Sweden‚ Europe‚ has substituted fossil fuels over a decade ago with biogas‚ which greatly decrease harmful carbon dioxide emissions‚ meaning it would not contribute to global warming. Harnessing renewable energy effectively can be done if the resources are present and there is support from the government. this essay will consist

Bio-fuels Menno van Amen TV4E 13-06-2013 The production of bio-fuels has become a controversial topic as the 21st century progresses. Lately the production of biofuels has been discussed quiet frequently and many people have started focusing on the question if the production of biofuels actually is environmental friendly. Firstly‚ what is a biofuel? Biofuels refer to any solid‚ liquid or gas fuel that has been gotten from biomass. They produce biofuels by growing plants‚ growing sugar

Cells Cells Cell division and cancer Victoria Brothwell Strayer University Cells Introduction Regular cells and cancel cells are extremely different. Depending on the cancer that one may have cancer cells have more chromosomes that are scattered which is for why cancer cells are formed. In cell division all living things obtain cells in which come from other preexisting cells. If normal cells are do not divide and make new cells then cancer will occur. In order of all cells to be

Advantages and Disadvantages of Renewable Fuels Solar Energy: Advantages: -Energy is free although there is a building cost. -Causes no pollution‚ however‚ energy may go into machines that produce pollution. -Solar energy can be used in remote areas where it is too expensive to extend the electricity power grid. -Estimated that the worlds oil reserves will last for 30-40 years whereas solar energy is infinite. Disadvantages: -Solar energy can only be harnessed when it is daytime

case of America’s Natural Gas Highway‚ the companies Clean Energy Fuels Corporation and Navistar International formed a strategic partnership in order to overcome the dilemma of consumers being unable to purchase cars that ran on eco-friendly fuels such as natural gas‚ electric‚ or biofuel because of a lack of fueling stations that supplied these fuels. There was a lack of these fuel stations because there were no customers for the fuels. To

Bacterial cells are Prokaryotic cells. These cells have several internal structures and surface structures. The cell walls are of two types‚ gram positive and gram negative. Out of all the structures‚ the two selected structures are the cell- wall and endospores. The cell- wall of bacterial cells is found in three distinct shapes such as spherical‚ spiral and rod shaped. The cell wall of the bacterial cells is composed of the proteins and polysaccharides. This is collectively called peptidoglycan
