CO2 Emissions Per Capita Per State

Posted on by

The graph I created is one that shows the annual CO2 emissions per capita per U.S. State with data up until 2017.

(I couldn’t get the chart to upload with better quality for some reason, so please use this link instead to view it as a PDF)

In metric tonnes, this data helps to show the amount of CO2 emissions produced per state per person. When looking at this graph, it is very easy to see where the high amounts of CO2 emissions per capita are found: states like Wyoming, North Dakota, and Alaska stand out as the worst offenders for CO2 emissions per capita. This is in contrast to states like New York, California, Oregon, and Maryland who comparatively have very small CO2 emissions per capita.

This could lead people to believe that states like Wyoming, North Dakota, Alaska, etc. are more responsible for the large CO2 emissions put out annually by the U.S. as opposed to states like New York, California, etc., but that would be incorrect. What this chart tells us instead is that states on this chart that appear to be putting out gargantuan amounts of CO2 are instead putting out large amounts of CO2 in comparison to their population. A state like Wyoming that has a relatively small population but large amounts of farming/agriculture could appear to produce extreme amounts of CO2 compared to a state like New York, when in reality New York could be putting out much more CO2, but due to its large population it doesn’t appear to be as extreme of a CO2 emitter as Wyoming.

Food Waste management in the U.S.

Food waste is a massive problem in the United States.  Currently, a large portion of food is wasted in the United States and this wasted food ends up in various places.  These charts document the pathways in where wasted food ends up after it goes unused in 2018.  The column chart on the left depicts the weight in US tons of wasted food and approximately how many tons of wasted food end up in each place.  As you can see, the largest number of wasted food ends up in landfills with 35,277,543 tons of wasted food managed by landfills.  This massive number dwarfs any other pathway for wasted food.  For instance, wasted food used on land application is only 259,448.  The amount of wasted food that ends up in landfills is 135.97 times greater than the amount of wasted food used for land application.  The pie chart on the left details the same numbers however this chart gives the percentages of where wasted food ends up. As you can see more clearly, all other pathways for wasted food combined are less than the percentage of wasted food that goes to landfills.  In 2018, 55.9% of all wasted food was sent to landfills and not used in any other constructive way.  Out of the 63,132,123 tons of food wasted in 2018, 35,277,543 tons of that food ended up in landfills.  Not only is it horribly unsustainable to waste  food, but the methods in which wasted food is used afterwards is even more unsustainable and is contributing to the problems that we are seeing today.

Construction’s Relation to Sustainability

Posted on by

More often than ever, as a nation, we are witnessing forests and woodlands being torn down. The most common reason for tearing down all of these trees is to start up a new construction cites. Although there are a surplus of different reasons that these trees and animals habitats are being torn down, it eventually all comes down to greed. Most of the buildings that are being constructed are money-making entities. Consider some of the following examples; apartment buildings, storage facilities, casinos, etc. In fact, the amount of trees that are being planted opposed to torn down is an incredibly interesting ratio.

Annually, 15 billion trees are cut down. On the other hand, only 1.9 billion trees are planted a year. That means that the ratio of trees that are cut down to planted is 15 to 1.9. Meaning, for every 1.9 trees that are planted, 15 trees are torn down. To help better understand this idea, “For the 15 billion trees that are chopped down each year, every person on the planet could have 3,000 rolls of toilet paper” (Kilgore, 2022). According to Jonah Bader, “President Joe Biden has announced an ambitious goal of net-zero emissions by 2050… The idea of “net-zero emissions” is that any remaining emissions can be fully offset by so-called “negative emissions” — methods of sucking carbon out of the atmosphere. Planting trees is the most straightforward way to do that. Trees absorb CO2 for photosynthesis and store it as cellulose and lignin, the main components of wood” (Bader, 2021). Furthermore, “Planting trees may also be the most popular climate policy. Even former President Donald Trump loved the idea. He championed an international initiative to plant 1 trillion trees, which would be enough to soak up at least a decade of global emissions” (Bader, 2021). The possibilities are endless when it comes to further studying the ways that construction cites interfere with sustainability.

Hot Dam! (Hydroelectricity)

Posted on by

Hydroelectric power is an alternative method to fossil fuel-driven mechanisms. Take, for instance, the Hoover Dam, which generates ~4 billion kilowatt hours per year, and is one of the nation’s largest sources of hydroelectric power.

Hydroelectric power plants and dams usually draw the majority of their power from a reservoir of water, whose output is then controlled by a gate-like mechanism. Potential energy is gained as the water flows down hill, and in the case of the Hoover Dam, power is derived from two ‘wicket gates’ which then reach turbines that control the main power output for the Dam.

Hydroelectric power, be it through dams or other resources, is responsible for ~71 of renewable energy used worldwide, the biggest contributors being the United States, Brazil, India, Russia, and China.

Hydroelectricity is unique in its versatility and application, as well as its vast potentiality in power capacity and drive. It is a form of renewable energy that we should consider making more use of.

Wasted Water and What We Can Do

Posted on by

Water is critical to all forms of life on our planet.  Without water, humans would not survive.  However, based on the statistics, it doesn’t seem that we place as much importance on water as we should.  In the US alone, a family can waste 180 gallons of water per week.  Even something as seemingly simple as letting the water faucet run for 5 minutes while washing dishes can waste 10 gallons of water.  As of 2015, each American was estimated to use an average of 82 gallons per day.  This wasted water has real affects on the United States, with 40 out of the 50 US states expecting some form of water shortage in the next decade, as was reported by a 2014 Government Accountability Report.  For something so vital to our very being, mankind sure doesn’t treat water that way.  The wasting of so much water annually can have serious ramifications on future generations’ water supply and we can even see some of these water supply issues faced today.

Water wastage not only harms ourselves and the environment but also harms people financially.  It is estimated that more than $380 could be saved annually solely by using WaterSense labelled fixtures and ENERGY STAR certified appliances.  Despite the negative statistics there are ways to manage and curtail the current wasting of water.  Apart from using certified appliances, doing certain small tasks such as turning off the faucet while brushing can have massive affects in the long run.  By turning off the tap while brushing, roughly 8 gallons of water per day could be saved.  Just simply turning off the water while brushing for 2 minutes could potentially save 2,920 gallons of water annually.

There is no one easy solution to stop the current situation of water wastage, but by being aware of the problem and actively looking for small ways to cut your own wasting of water, massive changes can be made slowly over time.
