Wind Energy!

There are many forms of non fossil-fuel based energy. But, for this post I will be specifically looking at wind energy. In order to understand wind energy, it is important to first understand wind. When the sun unevenly heats the Earth, that is when wind is created. Wind can then be used to create energy. Knowing this, wind energy is sustainable energy. It will continue to be a sustainable source of energy for as long as the sun continues to shine. Wind energy is caught by the giant windmills, called wind turbines, that tower over 100 feet in the air. Sometimes, the wind turbines work by themselves or they can also be connected to power grids or a solar cell system. When there is a decent amount of wind turbines clustered together it is called a wind plant, however only a handful of electricity providers use these wind plants to provide power for their customers.

Across the United States, there are 41 states have wind plants which have developed more than 100,000 jobs for American citizens. In fact, a wind turbine technician is one of the fastest growing jobs in America. It’s important to note that the wind industry is still growing and is nowhere near its peak. The most common use of wind turbines that are stand alone is to pump water. However, farmers could also use standalone wind turbines, as well as homeowners. When it comes to wind power, it is cost effective as it only costs “1–2 cents per kilowatt-hour after the production tax credit” (energy.gov). Lastly, the newly developing wind industry equals annual investments of over 10 billion dollars into the United States economy. This shows the promise and potential that the wind industry, as well as wind energy has.

Sustainable Fishing

There are many issues attached to the fishing industry: overfishing, bycatch, pollution, fish farming, and economics. This is why it is so vital to protect the fish and other marine life populations in the ocean. If the IPCC can determine and enforce sustainable fishing quotas the ocean will be well protected. But since the ocean is a global commons and there is no full authority over it regulations are difficult to make. Additionally, since the ocean covers the majority of our planet there is no way to actually enforce these regulations and ensure people/fishing companies are following them. There is one company called Seashepard that acts like a vigilante group which boards boats that are engaging in suspicious activity. Since the ocean is so vast it is also difficult to determine quotas since it is hard to figure out exact population numbers. Scientists often are estimating the population sizes of species and even then fishing companies still push for higher quotas. Even with bycatch and fish farming quotas have to be set. Bycatch because it is the unnecessary catching and killing of marine life while fishing. Fish farming because often fish caught from the ocean are used as feed for the farm bred fish. Additonally, the usage of sustainable fishing methods in terms of techniques used like long lines, and trollers. So in terms of mathematics there is a lot of estimating involved with fishing to establish effective quota levels that protect populations and encourage sustainable economic activity. There is an interesting documentary on Netflix called Seaspiracy that explains all the dynamics of the fishing industry. When buying fish look to see if it was locally sourced or fished sustainably and consumption is the driving force for the fishing industry so it’s important to support environmentally conscious brands.

Sustainability and Energy Conservation

One of the first things that has come to my mind on the topic of sustainability is the concept of energy conservation.  This can be accomplished in many ways, and through many different forms.  For example, some ways to conserve energy could be turning off the lights when you are not home, turning down the heat in the winter at night time or turning down the air conditioner om the summer when you go to bed.  These simple things can make a large impact on your own personal footprint.  For the purpose of this blog we will focus on the amount of energy that can be saved by simply turning off the lights.  Lets say that a incandescent light bulb is graded for 60 watts.  This light bulb will use approximately .06 kilowatts of energy per hour while it is on.  Over time this adds up not only in energy use but also in money to pay the bill.  If you were to turn off that bulb there would be a 100% decrease in energy obviously, with a decay factor of 1.0.  This seems like it is so obvious, yet not enough of us are doing this.  In the long run turning off your bulb is not only incredibly helpful for the environment but also for your wallet.  When thinking about sustainability it is the little things that we have to do that will make an impact.  If we are able to do the small things like I have listed above it will be beneficial for all.

Deforestation and the Consequences

Deforestation has become a serious problem in the past few decades. Forests around the world have been destroyed due to increased demands for lumber supply, as well as many other resources. Many people don’t know how important forests are to the ecosystem, however. Forests “help people thrive and survive by, for example, purifying water and air” as well as by “soaking up carbon dioxide” (worldwildlife.org). Recently, more attention has been placed on forests because of the raging wildfires that we saw in the Amazon rainforest as well as in Australia. It is essential that we maintain the integrity of our rainforests because it is the habitat for millions of animals, as well as a supplier of jobs for millions of people. Unfortunately “in the Amazon, around 17% of the forest has been lost in the last 50 years” (Worldwildlife.org). If this continues, a vital part of our ecosystem will be destroyed in the next centuries. When we talk about the huge amount of land that is being destroyed, many people have a difficult time visualizing exactly how much it is. To put it into perspective, “In 2019, the tropics lost close to 30 soccer fields’ worth of trees every single minute” (Worldwildlife.org). This is an incredibly large amount of land. By saving the forests, we are really saving ourselves. We need to put more emphasis on the conservation of resources and realize that although the earth is tenacious, we may do damage that is not reversible.
