The Alternative Source Of Energy

When the water or lava comes up from the inner core from either a volcano or from a geyser, the temperature of the liquid it produces would be able to produce the same result we get from using fossil fuel to supply our energy. Geothermal energy could possibly be used to directly heat buildings or used to power turbines and thus generate electricity.

Wind energy, one of the oldest forms of renewable energy used by humans, is produced simply by harnessing the power of the wind with wind turbines and generating electricity. Geothermal energy is energy from the heat of the Earth, and is drawn from locations with naturally heated water like hot water reservoirs and geysers or areas deep within the Earth accessed by drilling (NREL, "Learning About Renewable Energy"). Hydroelectric power, in simplest terms, uses the power of water rushing downwards to rotate a propeller attached to a generator that in turn produces electricity (Perlman). Another form of renewable energy is biomass, such as wood, biofuel, and bio-waste, which is burned to produce energy; however, it is not clean energy.

After explaining how geothermal energy works, the author cites historical evidence of the usage of geothermal energy. He or she explains how people benefitted from geothermal water as hot springs in ancient times. He or she further includes the Romans who used this source as a natural medicine to treat eye and skin diseases which is a

Geothermal Energy: it means the use of heated water and stream to power the power station for turning steam and heated water to electricity but it's expensive

Renewable energy sources started increase at early 1800 to late 1800s, being mainly wood. Water mills played also important part at this growth. As energy source it reached peak around 1875, and started decreasing when coal took his place as United states main energy source. Usage of renewable energy sources decreased slowly till 1975 when new technology was developed. This new wave of inventions brought for us solar, wind, geothermal and other new renewable energy sources. Usage raised little and levelled off after 1975, still being least used source of energy with hydroelectric power.

Geothermal energy is heat from the earth that is a clean and reliable source. Geothermal energy is converted to energy by steam that drives a generator and creates electricity. Geothermal energy contributes 12.5% of Costa Rica's energy. Costa Rica uses volcanic geothermal energy which comes from under the earth's crust, by extracting and cooling the steam it powers turbines that make electricity. An advantage of geothermal energy is that it is constantly generated and does not rely on the

Students of history says that the principal utilization of geothermal vitality happened over 10,000 years back in North America. Individuals utilized water from hot springs for cooking, washing and cleaning.The first modern utilize started close Pisa, Italy in late eighteenth century. Steam originating from characteristic vents was utilized to remove boric corrosive from the hot pools that are currently known as the Larderello fields.The first geothermal plant in USA began in 1922 with a limit of 250 kilowatts. It delivered little yield. Nonetheless, because of specialized glitch must be closed down. It was until 1946 first ground-source geothermal warmth pump introduced at Commonwealth Building in Portland,

Volcanoes are wondrous formations on the earth. Humans are fascinated by them but are often very cautious about volcanoes. They see them as explosive, lava spewing mountains often causing natural disasters. These are just some of the effects of a volcano but plus side to it is that its energy can be harnessed. Energy that can be used from a volcano is Geothermal Energy. It is a clean, renewable energy which uses the steam produced from vents and hot springs near volcanoes. In this paper I am going to prove why Geothermal Energy is good for the environment and the society. Firstly I am going to discuss what geothermal energy is. Secondly, I will discuss the benefits of geothermal energy to the environment. Thirdly I am going to show how geothermal energy is beneficial to the society around its source. Lastly I will compare geothermal energy to other energy sources and show why geothermal energy is the way to go.

Simplistically, a majority the generation of electricity on the grid comes from the combustion of fossil fuels to heat boilers that moves steam through a turbine. The spinning action of the turbine attached to a motor creates electricity which is sold on the power market. Other sources of energy can be used to heat the boiler, including nuclear fission, methane, and wood products. In addition, hydroelectricity and wind power can also be used to generate energy through mechanical action on the turbine/motor as well. Finally, but not exhaustively, power can be generated from the use of photovoltaic cells which convert the energy of the sun into electricity. Regardless of how it is generated, electricity has a very short life; it must be consumed or stored almost immediately after generation. Until the development of transformers, most electricity was generated on the site where it was intended to be consumed, due the inability to store it. (The Changing Structure of the Electric Power Industry 2000 : An

Throughout the entire history of mankind, the technological advancements that civilisations have made have always been tied in with the development of energy sources. The first human energy technology was fire, along with human labour as the major energy source. This has bee supplemented by animals for agriculture and transportation since at least the dawn of agriculture some 10,000 years ago. Wind and waterpower for milling grain have also been used nearly as long.

In 1831, scientist Michael Farday discovered the first form of electricity. He found that when a magnet moved inside a copper coil it created what is known as an electric current. This invention is known as a turbine generator. Even today, in full sized power stations this simple invention is still used and works very effectively. These power stations create mass amounts of energy to turn the turbines. Most of the time the energy is made from the heat, for example when coal is burned. More environmentally friendly power stations use wind or flowing water to turn these turbines. This is known as renewable energy because it will not run out, unlike when oil and coal are used.(3)

Geothermal Energy The human population is currently using up its fossil fuel supplies at staggering rates. Before long we will be forced to turn somewhere else for energy. There are many possibilities such as hydroelectric energy, nuclear energy, wind energy, solar energy and geothermal energy to name a few. Each one of these choices has its pros and cons.

In Iceland, the Philippines, and El Salvador, geothermal energy accounts for over 25% of national electricity production.

In the current state, most of the world is using fossil fuels, which are nonrenewable sources. Fossil fuels are cheap and limited. They will soon be depleted. The world needs to find a source of energy that is not only renewable but sustainable. Sustainable Energy is usually associated with renewable energy. This is because renewable energy is a continuous source. However, the sustainability of each of different types of renewable energy vary. Sustainable energy means that amount of energy that is used, is also generated. The idea of sustainability means essentially that overall the plant or building is net zero. A net zero building would greatly prolong further damage to the Earth.

In the early 2000’s, the latest view of climate change and its devastating effect on the environment had scientists, politicians, and the business community worried about the contribution of human activities from the production of greenhouse gases such as the carbon dioxide emitted by cars. The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, has forecasted a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century (The consequences of climate change, 2016). The explosion of industrial output is driven by the attempt to satisfy the voracious consumption and the increasing demand for consumer goods around the world. Rapid oil depletion has
