The single effect thermal vapor compression seawater desalination process is illustrated schematically in Fig. 2. This process uses low-temperature heat source such as waste heat from an industrial process or solar energy to generate fresh water. This system has two distinct advantages: First, it can utilize the low-temperature heat source in the range of 50 °C to 80 °C, which leads to lower grade energy is used. Second, seawater doesn’t need to be heated to a high temperature, which saves energy and reduces scale.
Another pro for fracking is the reduction of surface toxicity. Since all the chemicals are pumped underground they cause close to no damage to if they are released on the surface or in the air. It is then less likely to contaminate bodies of water and the air. It can lead to a major decrease in air pollution due to reduced carbon dioxide emissions and less dependency on nuclear plants and coal. Lower energy cost is also a big pro because since oil and gas are obtained locally, industries that rely on fuel resources can be affected because of lower energy costs.
Given the information provided in the film, I believe electric cars are a reasonable alternative to combustion engines because they don’t produce harmful emissions like gasoline cars do. According to the film, even the first electric cars were quiet, fast, and produced no exhaust. This is a clear advantage over combustion engines, which produces exhaust that contains carbon dioxide, carbon monoxide, and nitrogen oxide. Not only do they produce no emissions, but electric cars do not need as much maintenance as combustion engines do. This is due to the fact that there are no spark plugs or oil to be changed.
Although it has a possibility of harming the environment, fracking is great for the economy and is environmentally better than other resources such as coal mining. Not all people believe that the benefits fracking has overweigh the environmental effects. Many want fracking to end all together, but with the way things are looking right now hydraulic fracturing will continue for a long
Improvement in energy efficiency in construction makes energy more available which can be probably used alternatively; also, reduces the political instability risks which tend to arise because of energy price inflation for householders or energy shortages (UN, 2009). One of the crucial advantages of energy efficient construction is
Nuclear energy is a clean, safe, reliable and competitive energy source. Currently it is seen as the only source of energy to replace other part of fossil fuels which harm the environment and emits large amount of greenhouse gases. Almost no carbon dioxide, and sulfur dioxide or nitrogen oxides are produced in nuclear plants. Nuclear power should be deployed to replace coal, oil and gas in the industrial countries. In the future, nuclear electric power plants will also provide power for electric vehicles for cleaner transportation.
• Environmentally Friendly – This means that Solar Panels do not cause any pollution, which therefore does not affect the world negatively. • Reduces Electricity Costs – It reduces electricity costs because you can harvest your own electricity to use. • Shared Solar – Because Solar Energy can be run “off the grid” energy produced can be shared. • Low Maintenance – As solar panels are one piece it because a lot less risky that smaller pieces will fall apart or break which lowers cost. • Remote Areas – Solar Panels can help to provide electricity to areas which may be far from another electrical source.
Producing electricity requires energy to turn turbines and thus turn generators. Energy demand is likely to increase due to the increasing world population. Today, 68% of energy worldwide comes from fossil fuels, 13.4% from nuclear fission and 19% from hydro and other renewable sources. However, fossil fuels are
Renewable energy is important, because it provides many benefits, such as providing benefits to the environment, as it is from clean resources that have low environmental impact, and can keep providing energy for our children’s children’s children and the chain continues. It also helps develop jobs and economy as the U.S build renewable technologies that are sold overseas, helping the economy of the U.S and its trade increase. (Why Is Renewable Energy Important?. 2013) Well most of the renewable energy sources are being worked on to keep improved, as some still have points to be taken into consideration. One of them is the solar energy, which works by adopting the sun raise, and converting it into energy, it is being spread out widely today.
People would have a higher work morale because they would be able to make a lot more money than before so they would be more happy to work longer hours. A pro of raising minimum wage could be that their would be reduced government welfare spending meaning more money for important things like our army. We would be able to build more schools and get everyone an education with all the extra money. With reduced government spending we would be able to put more money into food stamps so that less rich people would be able to supply more food to the house.Government welfare supplies things such as medicaid meaning
