Define geothermal energy

There are many considerations that come with geothermal power. Even as a renewable energy source, it is important to weigh the pros and cons of geothermal energy to better understand how it can fit into the greater energy mix. Top pros and cons of geothermal energy Harnessing geothermal energy comes with some key advantages and disadvantages. Here are a few to keep in mind: Pros and cons of geothermal energy Pros of geothermal energy Cons of geothermal energy Reliable source of power Location dependent Small land footprint High initial costs Usable for large and small-scale installations Can lead to surface instability The geothermal energy industry is expanding Geothermal infrastructure has longevity On the pros side, geothermal energy is a reliable source of power that has a small land footprint compared to other renewable sources, it can be harnessed at both large and small scales, the industry is expanding, and its infrastructure is long-lasting. On the cons side, geothermal power plants can only be built in certain locations, they are often expensive to build at first, and they can cause surface instability and earthquakes. Below, we’ll explore these pros and cons in further detail. One of the biggest advantages of geothermal energy is that geothermal power is a very predictable and reliable source of energy, especially in comparison to other renewable energy resources like wind energy and solar energy. While wind and solar are more intermittent sources that require e...

Geothermal comes partly from the Greek thermos, "hot". Most geothermal electricity is provided by power plants situated in areas where there is significant activity of the Earth's great tectonic plates—often the same areas where volcanoes are found. But hot water from deep underground may be used by cities far from volcanoes to heat buildings or sidewalks. And a newer source of geothermal energy relies on a less dramatic kind of heat: Individual homeowners can now install heat pumps that take advantage of the 50°-60° temperature of the soil near the surface to provide heating in cold weather (and air-conditioning in the warm months). These very small-scale geothermal systems may eventually supply more useful energy than the large power plants.

Geothermal Power Conversion Technology refers to techniques used for the conversion of the heat content of geothermal fluid into mechanical power in order to drive a generator and produce electric power. The first 1/4 HP reciprocating steam engine unit was installed in 1904 by Prince Piero Ginori Conti in the Larderello geothermal field in Italy. Prior to World War II, there were already 136.8 MW of capacity installed in Larderello area. After the war more wells were drilled and modern power stations were installed in the area. As of December 2009, the current operator, ENEL, had 842 MW of installed geothermal power capacity in the Tuscany area. The first steam engine–driven generator of 35 kW was installed in the USA in 1921 in The Geysers of California. Only in the 1950s, the region was further developed and today 900 MW are produced in this area. In Japan, surveys began in 1918 with the first experimental generator installed on... Ambient: Natural condition of the environment at any given time. Baseload: The lowest level of power production needs during a season or year. Baseload plants: Electricity-generating units that are operated to meet the constant or minimum load on the system. The cost of energy from such units is usually the lowest available to the system. Binary-cycle power station: A geothermal electricity-generating station employing a closed-loop heat exchange system in which the heat of the geothermal fluid (the “primary fluid”) is transferred to a differe...

Renewable energy is Fossil fuels - coal, oil and gas - on the other hand, are non-renewable resources that take hundreds of millions of years to form. Fossil fuels, when burned to produce energy, cause harmful greenhouse gas emissions, such as carbon dioxide. Generating renewable energy Renewables are now cheaper in most countries, and generate three times more jobs than fossil fuels. SOLAR ENERGY Solar energy is the most abundant of all energy resources and can even be harnessed in cloudy weather. The rate at which solar energy is intercepted by the Earth is about Solar technologies can deliver heat, cooling, natural lighting, electricity, and fuels for a host of applications. Solar technologies convert sunlight into electrical energy either through photovoltaic panels or through mirrors that concentrate solar radiation. Although not all countries are equally endowed with solar energy, a significant contribution to the energy mix from direct solar energy is possible for every country. The cost of manufacturing solar panels has plummeted dramatically in the last decade, making them not only affordable but often the cheapest form of electricity. Solar panels have WIND ENERGY Wind energy harnesses the kinetic energy of moving air by using large wind turbines located on land (onshore) or in sea- or freshwater (offshore). Wind energy has been used for millennia, but onshore and offshore wind energy technologies have evolved over the last few years to maximize the electricity p...
