commencement of the ongoing catastrophe at the Fukushima nuclear facility in way to reduce crime rate essay Japan. This shift in attitude also coincided with a shift in location: from the computer desk to the laser lab. Exactly how far these trends might proceed is impossible to say: we are almost surely headed toward a simpler society, but no one knows ultimately how simple. What if renewable energy optimists are right in saying that solar and wind are disruptive technologies against which fossil fuels cannot ultimately compete, but renewables critics are correct in arguing that solar and wind are inherently incapable of powering industrial societies as currently configured, absent. The interest in serving and understanding people has never changed, yet I realized I could make a greater difference doing something for which I have a deeper passion, political science. The reason has to do with energy density: an electric battery typically is able to store and deliver only about.1.5 megajoules of energy per kilogram; thus, compared to gasoline or diesel (at 44 to 48 MJ/kg it is very heavy in relation. Well then, are the most enthusiastic of the solar and wind boosters correct in claiming that renewable energy sources are ready to substitute for coal, oil, and gas quickly enough and in sufficient quantity to keep the global economy growing?
We will need to maximize our passive capture of ambient, variable, solar energy using south-facing glazing, superinsulation, and thermal mass. Of the three main fossil fuels, oil is showing the most immediate signs of depletion, and renewable options for replacing it are fairly dismal. The crossover point, where fossil fuels cease to be cost competitive, could come soonperhaps in the next decade. In addition to just science, I am drawn to State University for other reasons. Realistically, our choice of replacements for fossil fuels is limited to energy sources that can be harnessed with current technology, even if they cant keep the industrial growth engine humming.
