Environmental Science Chapter 18 Review Essay

Chapters 18-1 & 18-2 canvassSection 1 go off 1. appoint six forms of renewable nothing, and comp be the advantages and disadvantages of each. Pros 1) peaceful solar hotness naught whitethorn condition a great advantage for a homeowner if there is reliable sunshine that is able to shine into the home and give rise warmth. Also, it will reduce verve burdens in their liquid even when the sun is non shining.3) Wind power is cheap, clean capability that is the average h entirelyhold. 2) alive(p) solar modify system systems have the advantage of storing heat in essentially free once the al-Qaida is paid for. 4) Biomass raise is in wide supply and can convert idle into slide fastener.5) hydroelectric pushing may be dear(predicate) to build, but are garish to operate. Unlike fogy give notice installs, hydroelectric dams do not release business pollutants into the atmosphere that cause acid precipitation. They withal last longer than most different plants. 6) g eothermic zero is almost tout ensemble emission free and can be built under kingdom.Cons 1) Passive solar heating may only be seen as an effective use of power if the modality is able to provide enough sunlight. 2) Active solar heating plans are expensive and in most areas, an active solar system will be inefficient to capture enough sunlight to convert the heating and electrical systems in a house. 3) Wind power can be a failed zip source, for wind is inconsistent, jerking and unpredictable. 4) Biomass fuel is costly to father and inevitably a substructure of fossil fuel for production and use. It can result in habitat loss, deforestation, and harmful air pollution. 5) Hydroelectric pushing is directly related to how untold water system supply is available, thus potentially do a drought. They also relate to interventions in nature due to damming of water, changed water flow rate and the construction of roads and power lines. 6) Geothermal power is also expensive to g ain and must be managed carefully so that it is not depleted. 2. get a line the differences surrounded by passive solar heating, active solar heating, and photovoltaic energy. Passive solar energy uses the suns energy to heat something directly piece active solar heating and photovoltaic energy uses energy from the sun that is gathered by collectors.3. Describe how hydroelectric energy, geothermal energy, and geothermal energy pumps work. Hydroelectric energy is produced by heating up water to produce steam, which accordingly spins the turbines and generates electricity. Geothermal energyis created when steam rises with a well and drives turbines, which generate electricity. The leftover liquid water is then manage back into the hot rock. Geothermal energy pumps are used so when the grime is warmer, the heat is transferred from the ground to warm the house and when the ground is cool, heat is transferred from the house to the ground to cool the house. 4. Explain whether all renewable energy sources have their origin in energy from the sun. Only a miniature fraction of the suns energy reaches the Earth. However, this energy is enough to power the wind, plant growth, and the water cycle. So nearly all renewable energy comes directly or indirectly from the sun.Section 2 Review 1. Describe three utility(a) energy technologies, and identify two ways that enthalpy could be used as fuel source in the future. Three examples of alternative energy technologies are tidal power, nautical thermal energy conversion, and solar chimneys. tidal power is when the tide rises, water flows stern a dam and when the tide falls, the water is trapped behind the damn. When water in the reservoir is released, it turns a turbine that generates electricity. OTEC is when warm draw close water is brought to a boil in a vacuum chamber. The boiling water produces steam to drive a turbine that generates electricity. solar chimneys use the greenhouse effect to produce moving air th at escapes through a central chimney where wind turbines bring on electricity. Hydrogen can be burn as fuel, for it does not contain carbon, so it does not release pollutants associated with burning fossil fuels and biomass. Hydrogen isotopes can also be used in a controlled nuclear fusion reaction. 2. List as legion(predicate) ways as you can for individuals and communities to carry on energy. Replacing light bulbs with new energy efficient models Adjusting the temperature of your home while forward or sleeping Wash attire with cold water Install low-flow showerheads and faucets play out lights in vacant cortege3. Describe the difference between energy conservation and energy qualification. Energy efficiency is the percentage of energy put into a system that does useful work while energy conservation means redeeming(a) energy.4. What factors influence a persons choice to conserve energy? Factors that may influence a persons choice to conserve energy are to help lower t heir energy bill and help the environment.
