The Pros And Cons Of Geothermal Energy

Some advantages to using geothermal energy are: potentially an unlimited supply; does little damage to the environment; does not produce air pollution; does not require any additional structures (solar panels or windmills) to collect the energy; and it does not need to be transported to the power plant. The major disadvantages to using geothermal energy is the need to dig deep below the surface causing damage to the soil when drilling test wells, availability is limited; and there is not much power per vent. This type of energy source would only be available in the Philippines, Indonesia, Mexico, countries of Central and South America, countries in eastern Africa and in eastern Europe, Italy, Iceland, New Zealand, Japan, France and very few places in the United States, mostly in California and Nevada (www.altenergy.org).

These alternatives can be helpful in reducing carbon emissions while ensuring the energy independence . These sources are wind ,solar ,geothermal, hydro, nuclear and renewable bio fuels. Some of these sources are renewable , meaning they can be replenished, while others like nuclear, are non-renewable, yet are clean sources of energy. For better sustainability , society continues to explore the challenges of these energy options to help implement the necessary changes for an environmentally friendly and energy independent future.

He or she cites a couple examples of geotheramal water usage in Oregon and New Mexico. Both of which used it as a heating source in various different applications. In Oregon, it was used to keep roads and sidewalks from freezing over during the winter season. Also in New Mexico, the same principle was used to to keep the soil beneath the corps from freezing which resulted in a longer growing season. These are great advantages that support his defence on geothermal energy usage.

When the wind is blowing on wind turbines it produces electric power, Fans are old techniques used in the mills and then the water pump, but now it has developed the technology and has become used for electric power production.

Coal: Electricity from coal is the power made from the energy stored in coal. Carbon, made from ancient plant material, gives coal most of its energy. This energy is released when coal is burned. We use coal-generated electricity for:

To begin with, Geothermal energy does not generate pollution. As coal power plants release the chemical energy inside the coal and transform that energy into electrical energy, they leave behind coal ash, while Geothermal energy does not leave behind anything. Coal ash can pollute the water it is dumped into, poisoning us, as coal ash contains mercury, cadmium, and arsenic. In addition, geothermal power plants have the smallest carbon footprint of any heating or cooling source. Something’s ‘carbon footprint’ is how much it contributes greenhouse gases to global warming, as geothermal energy produces little to no greenhouse gases when transformed into electrical energy. Finally, geothermal power plants have little to no effect on the landscape. Most of the geothermal power plant is underground, leaving actual plants more land they could grow on. However, how could Geothermal energy be

Coal is a type of fossil fuel that contains stored energy from dead plant matter. Coal is formed millions years ago in geologic time. When coal is burned the energy is used to heat water and generate electricity.

It can produce greenhouse gas emissions, unlike its competitors. So, should I really support an energy production method that directly contradicts my stance. Then again, promoting energy diversity is a number one goal in my opinion, and geothermal energy only accounts for less than three percent of B.C’s energy production.

Coal generates about 39% of the electricity produced in the United States. Coal is fossil fuel created from the remains of plants that lived millions years ago. To generate electricity from coal its burnt and the steam turns a turbine and its movement generates electricity. coal is a non-renewable energy source and releases Carbon dioxide and other harmful pollutants into the air when burnt. Therefore coal can be seen as an energy source not sustainable enough for the state of connecticut.

Geothermal energy has disadvantages too. The water usage, high construction costs, and etc are things that geothermal energy effects. It can be very dangerous and hard to drill into hard heated rock. Sulfur dioxide, and silica emissions are harmful too and could possibly kill somebody. Geothermal sites and locations contain harmful gases that are poisonous, and they can escape from deep inside the earth.

New Zealand is an island country in the South Western Pacific Ocean and it is located east of Australia. The country is small, similar in size with Great Britain or Japan, and their population is of four million people (wikipedia.org). According to australiareiser.no, New Zealand is known for being a clean country with a lot of green nature, high mountains, waterfalls, rivers and fjords. New Zealand can be compared to Norway. It has a lot of similarities, but what separates them, are New Zealand’s bamboos, palm trees, long white beaches, spouting geysers and active volcanoes.

The best place for geothermal energy is in West Jawa, because it is where many volcanoes in Indonesia are centered. A modern geothermal power plant can cost as low as $3400 per kilowatt installed. Unfortunately geothermal plants can pollute water and can affect the geological structure of the land where it’s installed. Geothermal plants produce fewer pollutants than coal plants and are also less than half the price. Indonesia has nearly half of the world’s potential resources in geothermal energy, yet the country only uses enough of their resources to make them number three on the world’s list of top geothermal using countries. More geothermal plants are needed in Indonesia to lower the carbon emissions and to start tapping into the resources below their island. Not only is geothermal power cost effective, but it is a smart choice for Indonesia

There are many natural sources on the Earth that show the heat and power within the Earth: geysers, hot springs, fumaroles, along fault lines, volcanoes, and mud pots, and that’s not all. All of those are similar but they are all a different

Now a days in all over the world majority of electricity is generated in coal-fired thermal plants, in which the coal is used for burned to boil water and the steam produced is expanded through a turbine, which turns a generator [2]. And at the same time low pressure steam exit at the end of the turbine and it is condensed by the condenser and returned to the boiler.

The North Island is more city like and has a trail of “mountain ranges running through the middle, with gentle rolling farmlands on both sides” (100%PureNewZealand). The North is also home to several active volcanoes. Since, New Zealand rests on “two tectonic plates: the Pacific and Australian”, these mountains have been in formation for over 500 years. Consequently, these two plates create the threat of earthquakes. In 2011, Christchurch has experienced a tragic earthquake. As for South Island, they are home to vast farmlands. Canterbury has the largest region of dairy farms and the greatest concentration of dairy cows. Be that as it may, the North actually has, “60% of dairy cows located in the North Island” (LIC).
