le published in How to Power the World, “the waste products of nuclear power contain “high levels of radioactive (materials which) is very dangerous. It lasts for tens of thousands of years before decaying to safe levels. It is highly radioactive and is probably the biggest hurdle we face if nuclear power is going to be taken seriously” (How to Power the World 2010). Nuclear energy has great potentials to augment sources of energy in the future. It use, however, should be further evaluated in terms its long term effect to the environment and the risks it poses to the existence of mankind.
Another article entitled An Ocean Breeze: Mapping Brazil’s Offshore Wind Power Potential written by Riebeek (2009) proffered his experience on “assessing the feasibility of an offshore wind farm southeast of Brazil” (Riebeek, 2009, par. 1). His project entailed measuring wind speeds using Nasa’s QuikScat. The limitations of using this approach coupled with other challenges including the number of turbines that must be built in their projected location showed that although this source of renewable energy is viable in Brazil, there are other factors that need to be seriously evaluated prior to its implementation. The high investment cost proved to be a barrier for implementation as private or public organizations need to examine if the returns on investment would justify the initial funds needed to support and sustain this energy source.
among all of its potential applications, hydrogens only waste or byproduct is H 2 O pure water, hydrogen fueled combustion engines actually clean the air they pass through (Alternative Energy, n.d., par. 3)
it is costly to produce, dangerous to store, difficult to transport, tricky to distribute and its volumetric energy intensity is much lower than that of other liquid fuels like ethanol or gasoline. Safety would be another problem and it would be an enormous job, and would take many years, to accomplish the logistics and
