Watt Will Save the World
Vehicles are a major tool for people in our day and age but the all the carbon it gives off could end up being a problem for the world. To help out the carbon problem in the world we may already have the answer, electric vehicles. We know that electric vehicles are green but are they truly green?
According to the article, The coming of Intelligent Green Vehicles, it states how electric vehicles themselves don’t emit any pollution and also list other facts on how electric vehicles can help the environment.
- Electric vehicles themselves don’t emit any pollutants and unlike your regular ICE (internal combustion engine) vehicles.
- The cars and trucks that we now use account for almost one-fifth of all U.S. emissions.
- Cars and truck emit nearly 24 pound of carbon dioxide and other gasses that cause global warming.
Even though electric vehicles themselves do not emit any pollutants, coal does. In order to make electricity you have to burn it and therefore causes carbon emissions. Many scientist believe that this is the down fall to electric vehicles According to the article, Burning Atlanta, “Electric utilities produce about two-thirds of all the sulfur dioxide emitted each year in the United States. They also happen to be the biggest stationary source of carbon dioxide—the principal greenhouse gas implicated in global warming, the nation’s most fearsome future air pollution threat.” (Whitman, 2005) Whitman basically says, that if you are getting your power from coal power plants that it is almost as bad as using ICE vehicle.
Although burning coal is the main source for electricity there are alternative ways to produce electricity. Here is a list of the alternative ways:
- Wave (Anchor a copper wire. Put a magnet around it. Move the magnet up and down (in this case, that’s the job left to the waves). This induces an electric current in the wire)
- Wind Energy
- Biomass (is material that is formed from living organisms, such as wood or agricultural wastes. Biomass can be burned to produce electricity)
- Geothermal (uses hot water or steam from deep beneath the earth’s surface to produce electricity.)
- Hydroelectric (the energy of falling water to spin generator turbines.)
These are just a few ways of creating electricity while being green.
As you have seen electric vehicles are cleaner than regular ICE vehicles, but thanks to technology, they are also becoming a better buy for consumers. Right now most electric cars are ran on Lithium-Ion batteries. with the help of some technology these batteries will be able to last longer thanks to ultra-capacitors. An ultra-capacitor is a device for storing electrical energy. According to the article, Drivers of Progress, “Right now, the best ultra-capacitors hold only about 5 percent as much energy as a comparably sized lithium-ion battery—not enough to power an electric car, but enough to work in a supporting role. “ (Dean, 2012). Even though they haven’t made a huge impact yet we will just have to wait and see if ultra-capacitors become the next big thing.
The Shocking Truth
As you have read you can see where electrical cars could help the world with its lack of pollution. You have also seen where it can hurt the environment you get your electricity from coal power plants, but with technology always getting better electric vehicles may one day become fully green.
