Question 1 : a) A wind farm power plant: The Good of a wind farm power plant is that wind energy is a free, renewable resource , so no matter how much is used today there will still be the same supply in the future. Wind is also a source of clean, non-polluting energy . Wind power consumes no fuel and emits no air pollution. Thus, it helps reduce the emissions that cause global warming. The Bad of a wind farm power plant is the high cost of construction of the turbines and transmission facilities. The technology of a wind power plant requires a higher initial investment than fossil-fueled generators. The Ugly of a wind farm power plant is some environmental concerns such as noise produced by the rotor blades, aesthetic (visual) impacts , and birds and bats having been killed ( avian/bat mortality ) by flying into the rotors. Moreover, the major challenge to using wind as a source of power is that it is intermittent and does not always blow when electricity is needed. Wind cannot be stored, and not all winds can be harnessed to meet the timing of electricity demands. Further, good wind sites are often located in remote locations far from areas of electric power demand (such as cities). Finally, a wind farm requires a large area of land, so wind resource development may compete with other uses for the land, and those alternative uses may be more highly valued than electricity generation. b) A solar power plant: The Good of a solar power plant is that solar energy is a free, renewable source of energy. Moreover, it is also a source of clean, sustainable, non-polluting energy. Thus, no fuel is required and no pollution will be created. The Bad of a solar power plant is that the initial cost is very high. It is very expensive to buy or build solar panels as well as a solar energy system due to the high-cost semiconductor materials. The Ugly of a solar power plant is that solar panels require a large area for installation in order to achieve a good level of efficiency. Therefore, barrens will grow due to high temperature at those sites. Moreover, the solar energy is inconsistent and intermittent. It is not available at night and also may not be accessible in case of bad weather conditions such as cloudy sky; thereby reducing the chances of it being totally reliable and requiring storage facilities. Additionally, solar power plant also consumes a lot of water.
