Tidal Energy

Tidal energy has the potential to be the future for harvesting energy. Tidal power is made through the natural cycles of the world’s tides which is caused by the gravitational pull of the moon and other celestial bodies. Tidal energy could function as a significant replacement for traditional electric production from coal. With tidal energy, it is all about finding the most effective location for capturing the tide. The most productive spots are where the range between high tide and low tide is the largest. There are three ways in which tidal energy can be captured; tidal turbines, tidal lagoons, and tidal barrages. Tidal energy is sustainable, renewable, eco-friendly, and is more effective than wind power systems. Like many other new energy routes and potential solutions to environmental issues, there are a lot of barriers to consider when implementing them that slow down the process.

The Power of Hydro Electricity

For this blog post, I chose to present information on Hydroelectric Power. It’s one of the oldest forms of renewable energy, which began use in 1950.

Hydroelectric power’s source of power is water and plants are usually located on or near a water source. The volume of the water flow and the change or fall in elevation is often referred to as head. The head from one point to another determines the amount of available energy in moving water. The greater the water flow and the higher the head, the more electricity a hydropower plant can produce.

There are about 1,450 conventional and 40 pumped-storage hydropower plants operating in the United States. The average lifespan of a hydropower facility is 100 years.

In 2021, hydroelectricity accounted for about 6.3% of total U.S. utility-scale electricity generation and 31.5% of total utility-scale renewable electricity generation.

Hydroelectric energy is sustainable because it relies on and uses the environment, benefits society, and can benefit the economy. It’s an affordable form of renewable energy that is more affordable than other renewable energy sources. Another reason why it’s sustainable is it’s been used for a long time.

Gallons of Water Wasted Per Day

For this week’s bog topic, I thought it’d be interesting to reach out to my friends and see how many gallons of water that they believe that they waste a day. Water waste is a huge issue when it comes to sustainability across the globe. Water can be wasted in many different ways and I feel that is often over looked. For example, keeping the water running when you brush your teeth, taking too long of showers, pouring out drinking water, etc. After reaching out to 10 of my friends, I put the data into a bar graph, which is pasted below;

The range of answers is quite obvious as one of my friend’s stated that she doesn’t waste any water, meanwhile, another one of my friend’s claimed that she wastes 20 gallons of water a day. By asking my friends this question, it was intended to make them think of all of the ways that they waste water and in return think of the ways that they can reduce water waste. Making these small changes can have a big impact on our globe.

2 Charts That Relate to Sustainability

For this Blog assignment, I made 2 charts. The first chart is a scatter plot chart. The second chart is a line chart. I inserted the links to my charts at the bottom because I can’t figure out how to insert the charts on this blog post.

For the first chart, I found that the average family wastes 180 gallons of water per week. I got this from the link below. I took that number and multiplied it by 4 to find out how much they waste in a month. I multiplied the number of gallons wasted in a month and multiplied it by 2 then 3 then 4 all the way up to twelve to see how much water is wasted for each month in a year. My first chart shows how many gallons of water the average family wastes in a year.

For my second chart, I found out how many pounds of food are wasted by the average American in one month. I got this number from the first link below. I multiplied 20 by 1, 2, 3, all the way up to 12 to find the amount of food wasted for each month.

Construction’s Relation to Sustainability

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.

Water Waste in Agriculture

The agriculture industry utilizes the largest portion of the water supply within that supply water is lost between poor irrigation, contamination, and poor management. Farmers and large agricultural plants have to establish water efficiency levels in order to reduce waste. Reduce, but not eliminate. Farms make up about 70% of all the water consumed globally and within that 70%, 30% is actually used and the other 40% is lost in waste. Unfortunately, due to the nature of the agriculutre industry (surplus) the usage of fertilizers, pesticides, and other pest replent techniques that are used on crops water becomes highly contaminated. This water can’t be reused without treatment and that is costly. The untreated waste water is then transported elsewhere but can still impose a threat to said environment. On the brighter side of things there are many ways in which farmers in the agriculture industry can reduce waste water. Such as efficient irrigation, capturing and storing water, crop rotations, and composting mulch.

Water is Life

Water. Water is an essential part of human life on Earth. We as humans are made of water, use water everyday, and need water to survive. It helps regulate all of our functioning parts of our complex bodies and ensures benefits of living a healthy life. Just as humans are extremely dependent on water, so are many other species such as the group of livestock. One animal in particular is cows, which are heavily connected to greenhouse gasses and Co2 emissions. Depending on the temperature that a cow is living in, the weight of the cow, and whether it is producing milk or not, correlates to the amount of water it needs daily. It has been estimated that for cows, “Daily water intake may vary from 3 to 30 gallons per day depending on age, body size (weight), stage of production, and the environment (mainly air temperature).” With an increase in temperature or lactating cows, this requires more clean water for them. But to put the stat of 3 to 30 gallons in perspective, every human is advised to drink 8 cups of water per day, which is half a gallon of water. So although cows are much larger than humans, their daily water intake is extremely large and crucial for them.

Water is an essential to everyday life but there is a ton of water being wasted annually in the United States. An article published by the Washington Post states, “The incredibly stupid way that Americans waste 1 trillion gallons of water each year.” 1 Trillion gallons of water is another worldly large number and the ways depicted that Americans waste water are water leakage, hoses, and irrigation systems: all are not needed waste methods of water. One way to prevent the wasting of water would be to be more aware of how you are potentially wasting water. This can be from fixing leaks immediately, shutting off your sprinkler system when not needed, and using less water related activities such as dishwashing and laundry. If there was to be less water wasted, the number conducted through the Washington Post of 1 trillion gallons, could be minimized by millions and millions. Not to mention saving water waste, but this can save thousands of dollars spent by homes and businesses.

One method of intaking water that is very popular is through bottled water. It is so popular because it is pre bottled, convenient, and can be disposed of. Although it is not economically and environmentally friendly, Americans live a fast paced life and want the fastest way to intake water. To put water bottle usage in perspective on Union College’s campus, let’s first say there are 2,200 undergraduate students. I’d say about half of the students here use plastic water bottles daily, so 1,100. If every student is drinking about 3 bottles a day, that’s 3,300 approximately, plastic water bottles. To calculate the amount of oil used to produce and ship the water to Union, I estimated around 15,000 gallons of fuel to get the water from Western states all the way to Union College.

Holy Cow that’s a lot of water

For this blog I decided to pick a cow as my live stock of focus because my home in Western Massachusetts resides in an area where dairy farms are incredibly prominent. When thinking about livestock such as cows and cattle, one may often think about how much they can provide for us but not often do we think about what farmers need to provide for them, ie, water. A healthy, non milking cow drinks somewhere between 9-12 gallons a day, while a healthy lactating cow drinks roughly triple that in 30-40 gallons a day. Holy cow that is a lot of water. The average human with access to clean water drinks about 3.7 liters a day which is about just under one gallon.

When thinking about water waste, my mind tends to travel to some very simple yet day to day things. Such as long showers or leaving the water running while brushing your teeth but something that strikes me is what I found in regards to food waste. Water is needed to produce basically everything that we eat and drink, therefore if we waste less as humanity, we save more water by having to produce less. In the United Kingdom, roughly 7 million tonnes of food and drink are thrown away each year with nearly 3.5 million tonnes of that still being edible. That is almost 50% less production that would need to occur saving billions of gallons of water.

The main reason that bottled water is so popular is due to its convenience. You can take it wherever you go and it is sold often in large packages. People also tend to have a discomfort with tap water being good to drink more-so than they do with bottled water. If you say there are 2,000 students at Union College, I would estimate that there is somewhere around 250 water bottles used each day. I imagine roughly 12.5% of the community drinks and recycles  (hopefully) at least one bottle a day. This is based off of nearly 20% of Americans using a plastic bottle each day and Union students are far more environmentally cautious than the average American.
