As we are theoretically reaching “peak oil”, “peak gas” etc. as well as the occurring of global warming and a number of environmental issues, the call for more “clean”, “sustainable” renewable energy has been increasing dramatically. However, some critics argue that renewable energy such as wind, solar, biomass, alone can not sustain the world in the future. In this essay, I will argue that renewable energy is not a viable way for replacing established energy sources by analyzing the geographic and natural limitations, impacts on ecosystems and the efficiency on cutting greenhouse emissions of renewable energies. The real solution should be reducing energy consumption.
Non-renewable fuels are organically-derived fuels. The original organic material, with the aid of heat and pressure, becomes a fuel such as oil or gas. These fuels are hard to come by and are sometimes harmful to the environment when burned. Concerns about these fuel sources has been very prominent in the past few years. Concerns greenhouse gas emissions and many other things such as energy security has caused for people to look towards a new source of fuel.
These opposing viewpoints include if we are using too much of them, the availability of them and how reliable they are. First of all, the first opposing viewpoint of this issue is if we are using up too much of our resources and how bad we are handling these issues. Here in America, we just resort to using our fossil fuels as our primary source of energy, but that has raised a lot of eyebrows and caused a lot of opposition. People of opposition did not like the fact of how these fossil fuels were being handled and how fast they were being used. Knowing that we have renewable resources, the opposing voices argued that we need to use less fossil fuels and more of the renewable resources.
To power our cars, should we stay with coal or use alternative sources? I strongly believe that we should move to alternative sources to power our cars instead of using coal. My reasons for saying this is because we have already got enough pollution in our atmosphere and we don’t need anymore. 42.1% of our greenhouse gases are produced from coal. Switching to alternative sources such as electric cars can help pull this number down significantly.
Within today’s society, there is a growing understanding of the problems related to fuel products. Climate change has been caused largely by CO2 emissions, the biggest man-made source of which is transportation. Due to peek oil being established and fossil fuels becoming slowly abundant along with its rising costs, stock products such as sunflowers and corn have come to the for-front in the advances in biofuel production. Due to their ability to be produced as economically sufficient, such biofuel alternatives are readily obtainable, technically feasible in application and have adequate properties of enthalpy, viscosity, flashpoint and engine efficiency as an unsaturated
In spite of this, if one compare this price to the amount of CO2 depleted by petrol and diesel vehicles , it gives the idea that if all classic cars would be supplanted with electric ones, CO2 emissions would be diminished by about 500 times. Despite the fact that Electric cars are moderately new at the mass production scale and are not yet answering many demands of improved expense, range and charging pace. Each of which will be aided by enhancing
(http://www.chemicalformula.org/reactions/combustion) Equations for Photosynthesis: Light Light Chlorophyll Chlorophyll Word Equation: Carbon Dioxide + Water Glucose + Oxygen Light Light Chlorophyll Chlorophyll Balanced Equation: 6CO2 + 6H2O C6 H12 O6 + 6O2 (http://www.chemicalformula.org/photosynthesis) Fossil fuels were formed over hundreds of millions of years ago by decomposing plants. After a long period of time, layers and layers of rock, mud, and sand covered the dead plants under the earth, which caused them to become fossilized. Oil and natural gas were formed in the same process as each other, but coal was formed differently. Oil and Natural Gas were formed by organisms - plankton and plants that lived in fresh water and were buried under rivers and oceans. The pressure and bacteria combined to make oil and natural gas.
Going green has a depicted itself as being a cure for the planet, and the answer to all environment problems. To my surprise at the time bring it is not. So why is going green not always be a good thing? To answer this question I looked into several areas; how energy is generated today and its impacts, the costs to companies for going green and the personal impacts to me for going Green. I also attempted to look at three specific properties: 1.
At one point, the idea of using a car that was electric powered may have seemed outrageous. Several questions emerged, such as: can it be done; would it work; how would it work; when would it happen; and how much would it cost. “Record-high oil prices have pushed consumers towards fuel-efficient vehicles and prompted many governments to consider electric transport as a way to escape their dependence on imported petroleum and to address climate change” (ebscohost.com). Here are a few of the many reasons why cars should be more efficient. First, cars should be more efficient because the cost to the consumer may decrease.
“The fuels are made by separating and chemically changing petroleum compounds, a process referred to as refining (Farrauto). Diesel and gasoline are both made up of many different hydrogen-carbons, which are “compounds of consisting of hydrogen and carbon elements” (Farrauto). However diesel carbon atoms are in longer chains than gasoline. “Diesel chains have 14 carbon atoms whereas gasoline chains have 9” (Farrauto). The main differences between diesel and gasoline are as follows: “a) A diesel Engine takes air into the cylinder and compresses it.
