Geothermal Energy?
I need to know the answers for a couple questions about geothermanl energy for a report.
I need to know:
#1: Who was the person who founded geothermal energy and when?
#2: What was the person’s resoning for researching that type of energy?
#3: Why were they trying to comeup with a new type of energy?
I tried to find these answers but I couldn’t find them anywhere.
adminsta answers:
The questions are kinda strange and the answers are really unknowable.
For example, no “founded” geothermal energy. The first person to use geothermal energy was the first human to decide that it was warmer in the areas of geysers (Iceland, Yellowstone, etc.) during the winter than it was elsewhere. That person used geothermal energy for heat.
Other examples would be the person who discovered that it was much cooler deep in a cave during the heat of the day than it was sitting on the hillside. This is another passive use of geothermal energy.
From the tone of the second and third question, I would think there is something very specific you are seeking which is not really clear in your questions.
Donald asks…
geothermal energy?
i need to make a chart of how much geothermal energy was used in the past years compared to how other alternative energy sources were used in the past years.
I know how Im going to do the chart, but I need the information. Ill keep researching on the internet, but I dont think Im going to find very much so if you have any information, please let me know. Thanks so much!
Other alternative energy sources are:
gas
oil
coal
hydropower
wind power
solar energy
etc.
adminsta answers:
Geothermal energy represents about 0.2% of the world’s electric power generation.
Oil 34%
Natural Gas 24%
Coal 29%
Nuclear 6%
Other 8% (including Geothermal)
Daniel asks…
Geothermal energy…?
Same science project… I need advantages and Disadvantages of geothermal energy and oh yeah it is a renewable source right…?
adminsta answers:
The advantages are it is relatively clean does and not use polluting fuels to generate energy.
The disadvantage are it is relatively expensive, geothermal vents are not always where you want them to be, and geothermal vents produce some very corrosive chemicals.
Now for the fun part you can use geothermal energy just about everywhere using a heat pump. The basic idea is that the earths temperature just a few feet below the surface is relatively constant. You can use that temperature difference to drive a compressor to heat/cool a structure with relatively low energy consumption.
Renewable well technically no once you use the heat it is gone, but the sun is the source of energy and unless someone extinguishes the sun….
Charles asks…
How can geothermal energy be used in the future?
The word geothermal comes from the Greek words geo (earth) and therme (heat). So, geothermal energy is heat from within the earth. We can use the steam and hot water produced inside the earth to heat buildings or generate electricity. Geothermal energy is a renewable energy source because the water is replenished by rainfall and the heat is continuosly produced inside the earth.
adminsta answers:
Geothermal energy can be used in the future as an alternative to fossil fuels and coal. It is a good source of energy because it does not cause pollution, and there is obviously a constant supply of it. This means that prices for geothermal energy will be consistent, unlike oil.
However, it is a hard technology to master, and can only be used in parts of the world where there is enough heat in the earth (think hotspots or underwater volcanoes). I think some of the Scandinavian countries are using geothermal energy.
Other renewable energy sources include hydropower, wind-power, solar power or nuclear power.
