documented (McConnell). Nuclear power is too dangerous an alternative, and so other renewable energy sources represent a more attractive alternative. These sources, which include biomass, geothermal, hydrogen, solar, and wind will pose minimal threat to an already degraded environment and relieve the huge American dependence on oil from the Middle East (McConnell). A longstanding criticism is that fossil fuels must be used in relatively close proximity to where it is being generated and that it can vary based upon geology, landscape, and climate (McConnell). However, with amazing twenty-first century technological developments, such barriers that once seemed impenetrable are being broken. Biomass or bioenergy is typically generated through wood burning products. This is one of the oldest energy sources, and continues to represent the vast majority of renewable energy currently being used by the United States (McConnell). However, plants and plant materials can also supply biomass energy as well, and are considered to be more ecologically compatible alternatives. Geothermal energy is just as its name implies, heat that is generated from the earth through sources of underground hot water or steam (Alternative Energy Sources 196). Many scientists contend that the practically unlimited energy contained in the Earths magma will represent an important alternate energy source in the future (Alternative Energy Sources 196). Presently, steam and binary are the two most common geothermal plant types with steam in the former type being used to turn turbines that generate electricity, whereas the more common binary plant operates using lower-temperature hot water (Alternative Energy Sources 196). Geothermal power has more similarities to conventional power plants than the other alternative sources, but the hydrocarbon fluids it uses, the massive heat rejection it requires, hamper its use, along with the lack of cool water that is ...
