Final Draft of Hydropower Persuasive Essay
Global warming is having a HUGE impact on the environment and in the future could change the way we live. Even so, we still have some time to save our earth. Alternative energies are the way to do this. Hydropower is a good alternative energy that is renewable as well. Hydropower already provides Vermont 22% of its total electricity. Hydropower doesn’t give off any green house gas emissions and is fairly safe for the environment. It is also very low cost energy and the power can be traveled far away from the water source. Vermont has 174,000 kilowatts of undeveloped hydroelectric potential according to several sources. I think that if there is so much potential electricity in Vermont that we need to invest in hydropower. Hydropower is a good alternative energy for Vermont because of Vermont's landscape, and it is more renewable than any other source.
Hydropower is good for Vermont because of Vermont’s landscape. There are numerous places where hydro power plants could be set up. Vermont has about 45 rivers located all over the state. Obviously, not all rivers are suited for having hydropower plants, but numerous could be. In Essex, there already is a power plant that is on the Winooski River. Water is not scarce in Vermont. Vermont rarely experiences drought, and Vermont gets a lot of precipitation per year. I think these facts prove that hydropower is good for Vermont. Vermont’s landscape is perfect for it. An average month, (not including winter), gets about 3-4 inches of rain. This means that the rivers will be raging, making the water wheels generate more electricity, which is good.
Hydropower is more renewable than any other source. Because of the water cycle, water is almost guaranteed to keep coming, compared to solar power, which doesn’t store any energy once it’s cloudy out. Or compared to wind power, if the wind is not blowing at all it doesn’t store any energy. You can’t rely on those types of sources like you can on hydropower. Hydropower is guaranteed to keep coming; the river isn’t going to just stop moving or stop running, especially in Vermont. In some scenarios, the river that a hydroelectric dam is generating its electricity from could dry up. This is very unlikely to happen, and it’s almost guaranteed not to in Vermont. Vermont hasn’t experienced a drought in many years. Vermont also gets a lot of precipitation per year.
Even though there are many advantages to hydropower there may be reasons why you wouldn’t want Vermont to invest in hydropower. First of all, the water wheels can damage the surrounding environment. Second, hydroelectric dams are going to have to be built, compared to have the solar panels give direct electricity or have the wind turbines giving direct electricity to homes and buildings. A way to solve the first problem is to attract the ecosystem downstream or upstream from the dam, so the water wheels don’t damage surrounding ecosystem. Even though it does damage the surrounding ecosystem a little bit it’s only in a small area which the water wheels are located. The ecosystem far away is not affected at all. A solution to the second problem is that yes, both the other sources do give electricity directly to the recipient, but the dams themselves barely affect the environment around them. Also, solar panels cost a lot of money. For the solar panels to follow the sun, you need a tracking motor. These motors cost $1000-$2000! Also the solar panels themselves cost a lot of money. Also the energy that is collected by the solar panels is DC. Most all appliances run on AC power. So to turn the DC power into AC you need an AC/DC converter. These can cost over $200! Also, wind power cost a lot of money. Wind turbines cost between $12,000 and $55,000! You also need to buy an AC/DC converter as well! When you choose hydropower you don’t run into the problems of cost. Even with these disadvantages there are solutions to these problems. The other sources have many other disadvantages far worse than these. The advantages of hydropower definitely out way the disadvantages of hydropower.
In conclusion, hydropower is the best renewable source for Vermont because of Vermont’s geography and in general it is more renewable than any other source. The world is changing fast because of the damage we have done to it. We NEED to do something about it now! Hydropower can offer a large amount of relief to global warming. Think about it, would you rather make change or would you rather have our earth destroyed forever. If you want to make change, than I think Vermont should take a step in investing into hydropower to cut down on green house gases.
