Geothermal Energy – The Other Renewable Energy

When it comes to renewable energy, wind and solar are the media darlings. Every time I hear renewable energy mentioned on TV or radio, it’s always wind and solar. If geothermal is mentioned, it’s an afterthought, and said almost under the announcer’s breath. Why? Given the immense importance of the United States’ (and the world’s) energy future, this is not the time to complacent. The stakes are too high as global warming looms large over our collective heads and the era of easily-accessible fossil fuels winds down. Our transition away from hydrocarbons to renewable energy is way too critical for any of us not to be informed about all available viable options.

Why you ask? Because informed and motivated citizens equates to political action which in turn starts the flow of money for development. We are all influenced by the media and public opinion. This is especially true of politicians. Why do you think they spend so much money doing polling. It is their way of determining what we, the public, want from them. We should also be wanting geothermal energy.

Solar and wind are viable alternatives but they have their detractions. So does geothermal. But given the facts, geothermal, at the very least, deserves equal billing. Actually, the US is already the world’s largest producer of electricity from geothermal. A fact that few, outside of the geothermal industry, know. According to the Geothermal Energy Association, “geothermal power makes up a total of 3.15 gigawatts (GW) of installed capacity in the United States, its largest producer, and more than 10 GW worldwide.” So, while geothermal gets fewer headlines and media attention it actually supplies more mega-watt hours of electricity than either wind or solar.

Geothermal power plants provide what is known as base load power i.e., they produce power at a constant rate, just like coal-fired, natural gas, hydroelectricity or nuclear power plants. Wind and solar energy are generally considered intermittent power sources. That doesn’t mean that wind and solar are unimportant, we need all three – four if you add in hydropower. Geothermal resources are not available everywhere, at least not for power plants. Home geothermal heat exchangers are used almost anywhere.

Fortunately, in the US, geothermal development is, albeit quietly, on the rise. According to the Geothermal Energy Association, “geothermal power projects grew 46 percent last year. That’s up from about 30 percent growth in 2008.” …

Interesting Power Facts

Geothermal Energy RenewableGeothermal power is renewable power source and will continue to make power for more than a number of years given that it is obtainable in abundant at few selected locations exactly where volcanic activity takes location.

Regardless of no matter if such a mega-project is feasible or no matter if Iceland’s citizens would be prepared to tolerate the monetary risk of creating the project soon after all they’ve lost in the country’s banking boondoggle, Iceland remains a model of what can be accomplished with renewable energy each in electrical energy generation-and equally as crucial in heating-when a nation puts its mind to it.

The average US well produces about ten barrels of oil each and every day. The average Middle East well produces two, perhaps three thousand per day. The US utilizes 22 million barrels per day. With half a million barrels pumping, the US produces only about half what it requirements. The US can drill child drill and by no means make close to what it demands. Drilling additional wells will make jobs, but not the oil that the US demands.

Water pumped from the earth’s surface is usually high in sulfur, salt and minerals. If the substances leaked into drinking water supplies, the water would be contaminated and unsafe for consumption. On the other hand, most geothermal internet sites use a closed-loop water system, which eliminates the concern. This method pumps the geothermal liquid proper back into the reservoir exactly where it’s contained in a steel nicely that is cemented off from surrounding rock. According to the Union of Concerned Scientists, there have not been any reported incidents of water contamination at geothermal sites in the United States.

Twenty seven countries including the United States had geothermal power plants in 2012, which generated around 68 billion kWh of electricity. The Philippines was the second-largest geothermal energy producer immediately after the United States at 10 billion kWh of electrical energy, which equaled roughly 15% of the country’s total energy generation in 2012. Iceland, the seventh-biggest producer at five billion kWh of electrical energy, produced 30% of its total electrical energy utilizing geothermal energy.…

Geothermal Energy RenewableGeothermal energy comes from volcanic heat stored beneath the earth’s surface. Underground reservoirs of water heated by volcanic activity can be tapped for steam to produce electrical energy. On Hawaii Island, Puna Geothermal Venture operates an sophisticated binary-cycle power plant. The heat from hot water in a heat exchanger generates vapor from a operating fluid with a low-boiling point. This vapor drives a turbine to generate electrical energy. The water, which by no means comes in contact with the working fluid, is then injected back into the ground to be reheated.

Location Precise – Good geothermal reservoirs are difficult to come by. Iceland and Philippines meet nearly one-third of their electricity demand with geothermal energy. Prime websites are often far from population centers. Climate transform is a moral problem. The persons who are going to be hurt the worst … are the men and women who live in poverty.” The Pope came out with his paper on the need to have to make modify. A steady resource – The power output of a geothermal plant can be accurately predicted. Not topic to the same low-energy fluctuations as with solar or wind.

Locally Created. Directly making use of geothermal energy in properties and commercial operations, such as meals production from local agriculture, can offset imported energy, keeping jobs, dollars, and other benefits in neighborhood communities. The United States leads the planet in the quantity of electrical energy generated with geothermal energy. In 2014, U.S. geothermal energy plants developed about 17 billion kilowatthours (kWh), or .four% of total U.S. electricity generation. In 2014, seven states had geothermal power plants. Excellent for meeting the base load energy demand (as opposed to other renewables such as wind and solar).

HS Orka pumps the waste geothermal fluids back in into 12 recharge wells, and of course, feeds some of the waste geothermal fluids to the popular Blue Lagoon. Tata Group firm Tata Power today mentioned it is hunting at the possibility of setting up a geothermal energy plant and a solar energy plant of 5 MW every at a suitable location in Gujarat, a move that will strengthen the renewable power portfolio of the organization. There are provincial renewable fuel mandates in effect in the provinces of British Columbia, Alberta, Saskatchewan, Manitoba and Ontario. British Columbia also has a Low Carbon Fuel Regular in location.

Binary cycle power plants operate on water at reduced temperatures of about 225°-360°F (107°-182°C). These plants use the heat from the hot water to boil a working fluid, usually an organic compound with a low boiling point. The working fluid is vaporized in a heat exchanger and utilised to turn a turbine. The water is then injected back into the ground to be reheated. The water and the operating fluid are kept separated for the duration of the whole procedure, so there are tiny or no air emissions.

There are three sorts of geothermal power plants: dry steam, flash, and binary. Dry steam, the oldest geothermal technology, takes steam out of fractures in the ground and utilizes it to straight drive a turbine. Flash plants pull deep, higher-stress hot water into cooler, low-stress water. The steam that results from this approach is utilized to drive the turbine. In binary plants, the hot water is passed by a secondary fluid with a substantially reduced boiling point than water. This causes the secondary fluid to turn to vapor, which then drives a turbine. Most geothermal …

Geothermal power is generated in more than 20 countries. The United States is the world’s biggest producer, and the biggest geothermal improvement in the planet is The Geysers north of San Francisco in California. In Iceland, many of the buildings and even swimming pools are heated with geothermal hot water. Iceland has at least 25 active volcanoes and several hot springs and geysers.

I recognize why everyone feels that geothermal energy is so good, but there are some negatives that come with the very good. The two experimental energy plants that have been produced have each had to be shut down. In order to do this at a industrial scale, the wells dug need to be relatively deep. Due to this, these plants knowledgeable earthquakes due to their digging. Im not saying its not a fantastic thought because it is a excellent a single. Nonetheless there will be alot much more testing prior to geothermal processes can be safe at an idustrial scale.…
