sources can be harmful. Thus, we must be careful what types of energy we use in abundance. Some of the main energy sources we use are: fossil fuels, nuclear energy, oil, and solar power. One main source of energy, perhaps the most used, is fossil fuels. Fossil fuels come from natural resources, such as, coal, natural gas, and petroleum. The fuels are nonrenewable, meaning once they are used up they are gone forever. Now, the fact that they are nonrenewable is not their only fault. The…

Global Warming Do human activities affect climate change, and as a result create global warming? Some scientists say no, but the majority of scientists say yes. They say human activities such as deforestation, using hydro-carbons, and burning fossil fuels, cause a lot of carbon dioxide to be released into the atmosphere changing the temperature of the climate, causing global warming. So now which group of scientists is correct? Does human activity affect climate change causing global warming? …

produced, which can be used for cooking purposes and as a fuel for vehicles that use natural gas. Another step to sustainability is converting from the large scale use of crude oil and coal to natural gas which is a cleaner source of energy, that produce equal amounts of energy to crude oil and coal but with much less CO2 emission. Natural gas, however, is still a non-renewable resource but it is also cheaper to access than the other fossil fuels because it is currently in surplus. International…

the case of humanity, not only does a generation leave behind its culture, but also the state of the Earth. Over the past 50 years, there has been a significant increase in the consumption of natural resources. In addition to the depletion of fossil fuels and natural gas, this increased consumption is damaging the planet; the increased carbon dioxide levels has caused the destruction of the ozone layer, and its level of protection to the surface of Earth. More of the sun’s dangerous rays reach…

conditions”(Energy Future). Therefore no extra fuel is needed as it would be in a coal or natural gas plant. The Nuclear Energy Institute reinforces this claim when the author voices, “Reliable nuclear power plants generate vast amounts of electricity, and extreme weather brings their value to the electricity grid into sharp focus”(Nuclear Energy Institute). In certain situations of extreme cold nuclear energy is the best case scenario. The plants don’t need extra fuel for different weather…

This even led to an increased migration of people moving to the suburbs and urban areas. Despite all these great advantages of the automobile it suffers from one major problem, which is pollution. This pollution is due to the large amount of fossil fuels consumed by automobiles, a problem that is resulting in a complete redesign of automobiles, away from the internal combustion engine and back to their roots (“The Automobile – Effects”). In conclusion, the automobile, since its invention has…

Coal and other fossil fuels were the main source of energy in factories across the globe which in turn meant that air pollution was on the rise. Burning of coal releases smog and cancerous particles into the air and further damages the ozone layer. The ozone layer protects the earth from the sun’s harmful rays, any damage to this layer allows the sun’s light to increasingly break through and increase the earth’s temperature. Furthermore, all fossil fuels have this effect…coal, oil and natural…

environmental group, Sanders proposed that “we need to transform our energy system away from fossil fuel and into sustainable energy” (Sanders Endorsed by Friends of the Earth). These proposals by Hillary Clinton and Bernie Sanders both aim to stop global warming by using renewable and sustainable energy instead of energy from fossil fuel power plants. However, they have not mentioned any regulations on fossil fuels like the Clean Power Plan. In order to shift to renewable energy first we have…

that come from human sources. These crafts emit gases and particles high in the atmosphere by doing so; they damage the ozone layer. Aircraft engines produce emissions that are similar to other emissions produced by fossil fuel combustion. When fuel is burned, the carbon in the fuel is released and bonds with oxygen in the air to form carbon dioxide. Scientific studies have shown that high-altitude emissions are harmful to the climate and the Earth. They are harmful to climate because they…
