What is geothermal energy? The thermal energy which stored in Earth since thousand years ago are called as geothermal energy. This energy is taking out from the shallow ground of the earth surface which having the temperature of 50°F to 60°F, or even deeper down to the absolutely hot molten rock which we called it as magma. The principle of this energy system is simple and easy. The system using solar energy where the energy is transferred from and to the earth surface. For example, the temperature of the pipes will be more constant in deeper part of geothermal reservoir which dig by human thousands years ago, thus, when there’s water passing through the pump heater, the water will be heated. The water pump heater was invented by a professor …show more content…
Any significant changes will bring impacts to our economic as well as environment. Thus, the demand of renewable energy, where the energy can be reused again, is increasing with the growing of economic in our world today. Geothermal energy is one of the renewable energy which is much more sustainable, environment friendly compared to fossil fuels which brings harm to our environment and our health. Environment will become more healthier and cleaner if the geothermal energy is being implemented in each of the countries as this system does not pollute our environment with those acid gases such as carbon dioxide and methane. (Conserve Energy Future) Unlike solar energy and wind energy, geothermal energy can be used and applied every day, is a continuous source of energy and provides constant …show more content…
This cause most of the aquatic animal failed to sustain their lives or failed to grow normally due to the chemical imbalance in water(Water Policy International Ltd). Besides, acid rain causes the water to be more acidic and damage the forest and weaken the tree’s natural defenses. Acid rain had increased the amount of nitrogen in forest and this leads to the decreasing of nutrients such as calcium and magnesium in the forest. (EPA, United States Environmental Protection Agency). Thus, by using geothermal energy, it will not cause any effects of ecosystem as it does not cause acid rain like fossil
A more long term effect would be stunted tree growth because trees need sunlight to grow
It uses flowing water to generate electricity. It does this by using dams and reservoirs for storage. This method gives us the most electricity rather than any other renewable energy source. Not only do the dams and reservoirs create electricity, they also control flooding (Sambu). Hydropower is the least expensive procedure to generate electricity.
Therefore these effects could be substantial. Scientists believe that the destruction of trees is a adding reason to the cause of global warming. Also the IPCC has estimated that if the climate rises 1.5 degrees celsius to 2.5 degrees celsius that 20% to 30% of plants would have high risks of extinction. The same would go for animals if the temperature continue to increase the same percentages of animals could face extinction as well. Now in the last 50 years heat waves, droughts, and flood have all increased.
You may think that solar energy isn’t enough but we can use it with other clean energy. It is a wise choice to use solar energy because solar energy is renewable and abundant, it is environmentally friendly, and it is also available around the world. Solar is the most abundant energy resource on Earth. In Taiwan, a three-story building with solar panels can produce three to four families’ electricity.
Introduction In today’s world, most developing countries are in a race to build up the necessary infrastructure to scale up there operations and become the next global superpower. In this process, a lot of energy is consumed – be it for transportation, manufacturing or construction. This rapid growth of energy use seen over the past two decades have raised concerns for governments and energy-related organizations alike. Questions with regard to the supply, sustainability and exhaustion of energy sources abound, and while most developed countries have taken active steps to reduce consumption of scarce resources, the position of developing countries in this regard is still lacking.
1. Introduction: Carbon dioxide (CO2) is one of the important green house gases (GHGs) emitted in the atmosphere through various human and natural activities. The human activities include rapid industrialization and urbanization, deforestation, excessive use of fertilizers in agriculture, excessive use of fuels, papers and many other manmade resources whereas natural activities include volcano eruption, forest fires, earthquakes etc. Emission of GHGs in the atmosphere leads to global warming which is one of the primary reasons behind the atmospheric changes that affect the human life directly or indirectly. The consequences of global warming are extremely harsh seasons, untimely rains, extended summers and floods that results in human deaths, destruction of flora and fauna in addition to the huge economical losses.
Environment- The replacement of fossil fuels with renewable energy (UCSUSA, 2013) will cause a decrease in CO2 emissions which will decrease pollution. By using renewable energy sources like solar energy, we also reduce our dependence on fossil fuel gas and oil reserves, which are becoming more expensive and difficult to find. It also reduces our dependence on imported fossil fuels, improving our energy security. Economic-
Hydropower 4) Geothermal 5) Solar All electricity sources, renewable and nonrenewable, have advantages and deficiencies. Factors are includes: • Maintenance cost • Feasibility analysis. • Initial cost.
wind energy and solar energy are both renewable types of energy they create no pollution and are fully sustainable as they are both powered by natural sources and if there is no wind one day the solar panels can generate energy and if it 's cloudy another day the windmills can generate energy also the energy created during the summer can be sold to the grid for extra capital that can be used for field trips, renovations, etc. Geothermal heating systems are rated the most efficient and eco-friendly heating systems. The system works using buried coils that contain a liquid, typically a mix of water and antifreeze. The liquid is warmed to the same temperature as the earth and then runs through to the home where a compressor extracts the heat but not only that geothermal heating requires no fossil fuels so it is very eco-friendly LED lighting is an efficient and eco friendly lighting alternative because they waste much less energy in converting to light compare to incandescent lights which waste 90% of the energy to convert to heat not only that LED lights last up to 15-25 times longer that traditional light bulbs this makes LED a much better source of lights than others because it wastes less energy and it is more efficient at doing its job this is so much better for the environment because it uses less energy that other lighting sources
Nepal attempts to achieve several sectors: facilitate water resources in everywhere, set reasonable price on hydropower electricity, and extend rural electrification to promote developments of rural economy (His Majesty's Government). Furthermore, Nepal government intervention on hydropower to fulfill the domestic electricity demand, and maximize the benefits of water resources (His Majesty's Government). Similar to Nepal, Turkey also considers economical aspect significantly; however, Turkey puts relatively balanced efforts on environments as well. Turkey’s policies are divided into two, which are “Electricity market licensing regulation”, and “utilization of renewable energy resources for the purpose of generating electrical energy” (Erdogdu, Erkan). In order to approach, Turkey views the advantages and disadvantages that hydropower impacts on economy critically (Erdogdu, Erkan).
Almost none of the fuel sources that we could use provide Co2 or other pollutants. Economic values could also come from renewable energy. Most of the Energy projects are located away from big cities. These benefits could bring local service as well as tourism. Although the pros are very big there are some cons.
In addition to that, geothermal reservoirs naturally replenish themselves, thus excluding any requirement for artificial resources. Geothermal plants themselves have an extremely small footprint on land, as almost all geothermal plants are built partially underground. Furthermore, geothermal energy can be accessed in almost every single corner of the globe, thus meaning basically every country can harness it. The sheer amount of energy that geothermal plants are able to generate yearly is equal to almost every single other major renewable energy source (such as solar energy, with over 11,224 megawatts generated yearly by only 24
Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves, and geothermal heat. It is the energy which is abundant in nature. The sun is the ultimate source of energy. Almost all the energy that we use eventually comes from the Sun. The exception is the heat of radioactivity deep inside the Earth, which is ultimately responsible for processes taking place inside the Earth.
The energy provide is mostly used for desalination plants, power plants and water pumps. This method isn’t fully developed and so it is not that
Nuclear Power Introduction People in the world are not in common when it comes to power-supply. Some say that coal power is the best option because it is cheap, or solar power because it is environmentally friendly. Because of the global warming is going faster than ever we have to ditch coal- and oil power and start using other energy sources. Nuclear power is one of the best candidates.
