Question
Read this carefully! The way blog assignments will run is that an initial topic is assigned below, you will have a week to make an initial post. Posts should be well written and adhere to good English grammar, punctuation, and spelling. Also, sources must be cited and linked to! Initial Post, Week 1 (due 2/17 by 11:59pm, 30 points): For your initial post, propose a new environmentally-focused law. Make is reasonable, but it can be one that might be difficult to get enacted (such laws are proposed all the time!). Your proposed law could be based on your views on how human beings use the environment, and should be supported by evidence you collect from your own research, primarily accomplished by browsing online news and other media sources. For example, you might want to propose a law encouraging new development in alternative energy, and you might find wind energy fascinating, but you realize there are problems associated with setting up wind farms, and you find a neat youtube video showing that problem. You’d post that video, and then how your law might circumvent that problem. That would be your initial post. Comments, Week 2 (due 2/21 by 11:59pm, 30 Points): During the second week of the assignment, you should take time to view the laws proposed by your fellow group members. You’ll have the week to consider their posts and make comments. You should comment on at least three of your group members’ blog posts and your comments should be substantive – a post saying “good law” or “I agree” will not earn you any points. Third, and final, Post, Week 3 (due 2/28 by 11:59pm, 40 points): For the third week, you’ll politely offer your opinions on which proposed law would be most likely to be enacted and why. Make sure to address comments your group members may have left you.
Explanation / Answer
Geothermal energy is the heat energy that is stored and generated within the earth. The internal energy of the earth is the heat energy generated from the radioactive decay and the continuous loss of heat from the earth's formation. Geothermal energy utilizes the heat trapped within the earth to generate electricity. Conventional geothermal energy use steam from natural sources like geysers or by extracting hot water from the hot, high pressure depths of the earth. These hot vapours are then used to drive electric turbines. Geothermal energy is a major source of energy in the Iceland and approximately 25 percent of the energy is derived from the heat generated within the earth.
Scientists have studied the volcanic system at Reykjanes Peninsula in Iceland which was dormant for more than 700 years. The depth of the Reykajnes geothermal field have never been explored. The IDDP spent 168 days drilling into this geothermal field. The drilling of well started in August 2016 and was completed on January 25, 2017. The depth of the well was 3 miles. The hole does not enter the magma chamber at this depth and instead penetrate the rock surrounding it. The temperature of the hole measured to be about 800 degree Fahrenheit. Research will continue through 2018 how the volcanic thermal energy can be used.
The heat is derived from the supercritical water in case of volcanic geothermal energy. The energy from the supercritical water is much higher than the conventional geothermal steam. The extreme heat and pressure brings the water to the supercritical state where it is neither liquid nor gas. The water can carry more energy in the supercritical state than normal steam. This energy from the supercritical water would generate about 10 times of the power output from other sources. So more power can be produced from deep supercritical wells than conventional geothermal wells. So fewer wells are required to produce the same power output which in turn leads to less environmental impact as well as improved economics.
