Biofuels As Clean Alternatives For The Future

Biofuels will Help Us Fight Against Climate Change

The inevitability of climate change needs to be minimized as much as possible, and alternative fuel sources are a part of the answer.


Our planet is a delicate place when it comes to the universe, as we have landed right in the sweet spot that is needed for our existence. As we explore more of the universe, we find planets similar to ours, but right now, space travel on that level is too difficult for us to get reckless with our own planet. However, we still do.

While a slight uptick in temperature or sea level may not seem important, it ruins ecosystems all over our planet, and it's not crazy to say that increased emissions have damaged our public health. Rather than finding solutions to our issues and facing facts that are important to human life — not only now but across generations — people shy away from the truth and focus on less important things. I've even done so myself, and I know that I should not. I like politics way more than an average person, but even then, climate change has always been just an issue I was aware of but have not fully cared about.

When I stopped to think about the importance of this, I realized that to me, it should be important. I want to be a biochemical engineer, and a part of that is the creation of alternative, biologically based fuels. In other words, biofuels are fuels based on living organisms, typically plants or microorganisms that are capable of producing substances such as ethanol from sugars. While biofuels alone can never solve our planet's climate issues, it provides a way to minimize emissions by up to 60 percent considering the source and how it's made.

Ethanol may seem familiar, as most gas in the United States is of some amount of ethanol — that amount can go up to 10 percent ethanol. Higher percentages of ethanol cannot be used on many cars, only on fuel flexible vehicles, and the percentage can range from 51 to 83 percent of ethanol.

Ethanol is alcohol made through fermentation, just like alcoholic beverages. While there are some downgrades to using ethanol, the development of ethanol is important, and if it can be more cost effective with less damaging materials. Corn and sugar canes aren't the most effective materials, and ethanol companies along with governments are looking for less harmful materials, such as fast growing grasses or microalgae. I personally wish to study Kudzu and produce ethanol from the sugars present in the plant to make use of the invasive species.

Microalgae are a relatively new source of biofuels and have actually been used in dietary supplements and used for overall health benefits. They are seen as potential sources of biofuel for the amount of sugars and fats that can be produced and then converted into ethanol. So it's obvious that since there are many sources available and in development, many forms of biofuel will become cheaper as time goes on.

However, one must consider the disadvantages of biofuel along with the considerations that need to be made.

Biofuels are less energy dense, so unless the production process is streamlined then perfected, it is hard to say whether it can be cheaper than gasoline itself. This can also be assisted by a carbon tax or a tax credit for biofuels. We had the ability to master fossil fuel extraction, which has reduced the cost, so the same should go for biofuels. Another common issue brought up is land use, and the production of biomass. The argument that is used here is that biofuels will create the need for cleared out land and require more energy to produce than is given.

Again we see the issue of streamlining and perfecting the process, but land use is important to many industries in agriculture, not just farming, so an increase in land use can be due to a variety of factors. Other methods of acquiring ethanol, such as microalgae and cyanobacteria, can be used to decrease this phenomenon.

One of the best benefits from biofuels, other than helping the environment, is the ability to be renewable, unlike fossil fuels. Once we run out of oil, we can rely on biofuel to be there. The oil and coal industries actually get more subsisdies from the government, but it's fighting against the inevitability of coal and oil being rendered economically useless. The future needs biofuels as sustainable energy, and we need to be here to cultivate it.

For a long time, Goya has been a staple in some Latino households. People carry around jars of Adobo when they eat at friend's houses and packets of Sazón Goya can be found in almost everyone's pantry. Many BuzzFeed lists, videos, and memes aimed at Latinos reference Goya somewhere.

But in a year that just keeps hitting us with bad news, Goya Foods CEO Robert Unanue said that Trump was an "incredible builder" and that the US was "blessed" to have him as president at a White House event on Thursday.

Raven Baxter Was Our Favorite Teen Fashion Icon And We're Still Recreating Her Best Looks, Here

We take a look at Disney's most fashion-forward show to recreate some iconic looks.

Disney Plus

I grew up in the early 2000s. And, like any child at the time, I was hooked on Disney Channel shows. My favorite was and is "That's So Raven."

Raven is a teenage psychic navigating life in hopes of not revealing her powers. Only her family and close friends know she has them. Her powers oftentimes get her in trouble, which is where the comedy comes in. But, they also teach her and her friends sentimental life lessons.

Sobriety is so underrated, even when it comes to healthcare. The instant gratification of a substance or drink isn't exactly as gratifying as some people may think. For those of you who've never been hungover, consider yourself lucky — a hangover is biologically horrifying. A hangover is not instant gratification, so who are we kidding when people say "it just feels good." Being healthy actually feels good and won't hurt you or your bank account in the morning. The best way to be healthy is to choose sobriety.

Ah, yes. The juice cleanse. Yet another popular diet trend that promises to magically solve all of your health, nutrition, and weight issues.

When you take a close look, juice cleanses aren't as magical as they are made out to be, and in fact, they might do more harm than good.

Unauthorized Plastic Surgery Is Totally Unethical, And Happening WAY More Often Than We Know ‬

Plastic surgery for cosmetic enhancements has you looking more botched than beautiful and it’s painful to see.

Coming from someone who could afford numerous cosmetic enhancing procedures I would never in a million years cut up my face or my body. I'm pretty emphatic and when I watch these brainwashed victims with bandages and chronic inflammation (swollen lips) I literally feel their pain.

I've never been big on casual wear or athleisure. Most people who know me have never seen me in sweats. But, I do have those two or three pairs of sweats I can't resist climbing into the second I get home, the newest addition of which is the extra cozy Odyssey crewneck sweatshirt I got in an XL size to feel as close to being wrapped in a blanket at all times as possible.

In the past several months, I've started to expand my horizons, considering the ways in which I can bring my small wardrobe of comfortable bedroom clothing into the public. I've experimented with topping leggings and a sports bra with a denim jacket to the park, and an oversized sweatshirt worn as a dress, cinched at the waist with a belt when I'm out wearing leggings.

The waiter briskly moves towards us and stops just a foot away table, balancing the black serving tray stacked high with the ceramic plates that make-up our dinner. From memorization, he beings gently, but purposely, sliding everyone's orders in front of them and within seconds I'm am starring my meal.
