Environmental Science Chapter 18 Review
Chapters 18-1 & 18-2 Review
Section 1 Review –
1. List six forms of renewable energy, and compare the advantages and disadvantages of each. Pros: 1) Passive solar heating may hold a great advantage for a homeowner if there is reliable sunlight that is able to shine into the home and create warmth. Also, it will reduce energy bills in their liquid even when the sun is not shining. 3) Wind power is cheap, clean energy that is the average household. 2) Active solar heating systems have the advantage of storing heat in essentially free once the infrastructure is paid for. 4) Biomass fuel is in abundant supply and can convert waste into energy. 5) Hydroelectric energy may be expensive to build, but are inexpensive to operate. Unlike fossil fuel plants, hydroelectric dams do not release air pollutants into the atmosphere that cause acid precipitation. They also last longer than most other plants.
6) Geothermal energy is almost entirely emission free and can be built underground. Cons: 1) Passive solar heating may only be seen as an effective use of power if the climate is able to provide enough sunlight. 2) Active solar heating plans are expensive and in most areas, an active solar system will be unable to capture enough sunlight to replace the heating and electrical systems in a house. 3) Wind power can be a failed energy source, for wind is inconsistent, unsteady and unpredictable. 4) Biomass fuel is costly to produce and needs a substructure of fossil fuel for production and use. It can result in habitat loss, deforestation, and harmful air pollution. 5) Hydroelectric energy is directly related to how much water is available, thus potentially causing a drought. They also relate to interventions in nature due to damming of water, changed water flow and the construction of roads and power lines. 6) Geothermal power is also expensive to obtain and must be managed carefully so that it is not depleted.
