People nowadays are all about conserving energy. A novice environmentalist would think energy is abundant, which is true, but at the same time it isn’t. If you think about it, cars wouldn’t work without gas, humans wouldn’t work without food, and lights wouldn’t work without electricity. Everything on earth has energy needs; even the smallest most non-influential and sometimes not visible organisms need energy, although when it comes to plants they can produce their own energy through a process known as “photosynthesis”. Humans are always trying to come up with the next best idea for “clean energy” such examples consist of windmills, dams, and in this case biodiesel. Biodiesel is a fuel consisting of a long-chained vegetable oil or animal fat base that is supposedly beneficial to the environment when used the fuel cars. Yet even after the multiple tests it must have undergone in order to be approved, it is now causing respiratory illness; you really can’t win when trying to come up with clean energy alternatives. “With fossil fuel reserves dwindling, developing renewable alternative fuels is important,” said postdoctoral fellow Dr. Nicholas Surawski. “But we should be particularly careful to protect against unwanted respiratory illness when we adopt new transport fuels.” Three fuels were tested at 20, 40, 60, and 80% biodiesel. The soot left when burned or used has been linked with respiratory illness multiple times in the past years. The scientists are glad this discovery was made because now they know something was wrong and needs to be corrected. Energy doesn’t just appear, it needs to be created; such is stated in the first law of thermodynamics. And sometimes the energy isn’t the cleanest or most beneficial in a case like this.
