KC3 - Cause and Effect Essay Draft

TOPIC: Renewable Resources
SUBTOPIC: Biomass Fuel

Renewable Resources: Biomass Fuel

Hawaii has been dependent on foreign oil and imported fossil fuels. Now, oil prices and gas prices are rising, and the demand for these fuels are high. Hawaii needs new and better ways to produce energy. What better way to do that than by using biomass fuels? Biomass fuels (aka biofuels) are renewable energy from plants and animals, and refer to anything that can burn or decompose to provide energy and power. It is more suitable than fossil fuels, and can be implemented directly or with relatively low investment costs. Using biofuels can help make the world cleaner and greener, but sometimes, the process to making biofuels can be harmful to the environment if not controlled properly.

Global warming, air pollution, and greenhouse gases are some of the reasons why Hawaii needs to start using biomass for energy. There are different types of biomass and there are different ways in which we can convert them into energy. The different kinds of biomass are wood, crops, garbage, landfill gas, and alcohol fuels. The usual way to produce biofuels is to burn it. But burning biomass isn't the only way to release its energy. It can be converted into methane gas or transportation fuels, such as ethanol and biodiesel. Corn and sugar cane can be fermented to make ethanol. Biodiesel is made from left-over food products like vegetable oils and animal fats.

Another reason why we need new resources for energy is because oil and gas prices are increasing , and the amount of fossil fuels are decreasing. We have been too dependent on these resources, and we need new solutions. Hawaii gasoline prices historically are higher than on the mainland and follow trends at a slower pace. Critics have argued that oil companies have kept their prices fictitiously high to take advantage of the small businesses in Hawaii.

Using biomass for energy may cut back on waste and greenhouse gas emmisions. Landfills can be a source of energy too. If we burned all the garbage and waste in landfills for energy, there would be less trash in landfills that get buried! But burning these wastes can release harmful chemicals and substances, such as carbon dioxide and carbon monoxide. Even though the process may be unsafe, using fossil fuels are much worse!

Biofuels are currently providing 4% of the energy used in the United States and 14% globally. Using biomass for energy is more suitable than fossil fuels because it costs less and is abundant in Hawaii. Hawaii has enough arable land to meet our fuel needs. 200,000 acres of 675,000 acres of land are being used as prime agricultural land.

In conclusion, biomass is a good solution and alternative to oil. Making use of wood waste and other waste products can help reduce the trash put into landfills. And using biomass can also help reduce air pollution and the emissions of greenhouse gases. There are still many issues to be worked out with ethanol and biofuel, but these alternative fuels may play a bigger role in meeting our energy needs for transportation in the future. If Hawaii makes the change to go green (and as green as possible) we could cut the demand for gasoline below 300 million gallons per year by 2025!

    i like you essay,
    especially when you explain why we should have biomass fuels & the results if we make this happen in hawaii.

    but i think it would help us have a better understanding if you told a little history. (if theres no history for hawaii on biofuels then nevermind.) hahaa,

    overall, this essay is done well (:

  2. Hey Sharmaine :) Nice Rough Draft! Okay, I'm going to be critiquing your essay by paragraph.
    ******
    [1st paragraph]
    -Nice start-up! But in the first sentence instead of putting: "Hawaii has been dependent on foreign oil and imported fossil fuels." You could put: "Hawaii has been dependent on foreign oil and is still importing fossil fuels." or something like that.
    Also in your 2nd sentence, you put: "oil prices and gas prices" I suggest you put "oil and gas prices". Avoid repeating the same word in a sentence.
    I like how you imply that you're gonna be talking about BOTH pro's and con's.

    [2nd paragraph]
    -Corn and sugar cane are used in biofuels? OOH! COOL! :) sorry, but that caught my attention :D that's a good fact to put in there. It catches people's attention, like me! :D

    [3rd paragraph]
    -You said "We have been too dependent on these resources, and we need new solutions." You have already mentioned that in your first paragraph so, you can probably remove that sentence. Unless, you want to revise it and make it sound different. Example: "Since our world is being so incidental to the use of our resources, we can now get our hands on ways to help this substandard conflict." You know? Haha. WE CAN CHANGE THE WORLD! haha, sorry.. i got too much into the whole going green mood. :P yeah, i know what your thinking... i'm so random. anyway, back to the point.
    -Nice... you talked about our high gas prices. BIG THUMBS UP FOR YOU! this can help in promoting biofuels to car owners.

    [4th paragraph]
    -So this is where you start your effects, i believe? Well, this is a good informational paragraph. Nothing bad to say about it. ^_^

    [5th paragraph]
    -14% in a whole country? Wow. Anyway, this is also a great, informational paragraph!

    {Final Paragraph]
    -I think the first, second, and third paragraph belong in the "effects" part of the body. Because thats how your essay is formatted right? Causes then Effects? Well, yeah.. you should put them in the effects part. Yes! LETS GO GREEEEN! :D haha.

    *Your thesis statement is CLEARLY represented because of the ideas you have supported! Nice work. Your essay also shows that you understand your subtopic VERY well. Your sentences are all varied and aren't boring to read. Your organization is pretty nifty! Except those three sentences I talked about that could be put into the "effects" part. Grammar errors are only in the first sentence. Other than that... YOUR ESSAY IS SPECTACULAAAR! :D

  3. Hi Sharmaine,

    Your essay is clearly written and organized and you make the connection between the renewable energy source and Hawaii's needs very nicely in each section of your essay.

    Proofread carefully before submitting the final...there are some subject-verb agreement errors.
