Question by Pheonix: What are 7 different ways to reduce pollutants in the atmosphere? ?
it cannot include energy sources such as solar, wind, hydro, or geothermal power–and it cannot be hybrid or electric cars.
it CAN be products, machinery, or any technology used to reduce air pollution.
please have a link to the info.
Answer by Feline luvr I know one way. we need to save energy, because when we waste energy, more fossil fuels are burned, which cause air pollution, and sometimes even acid rain.
Question by Becca: Can you use geothermal energy in your home?
I’m doing a major project in science and I need to know if geothermal energy can be used in the home. It’s going in as a test grade, and if it can be used in the home what advantages/disadvantages can it have on a home in the midwest say like Iowa, with horribly snowy winters and incredibly hot summers.
Answer by shan yea, it’ll cost a whooollllleee lot of moneys though!

Question by : What are the benifits to living near a volcano?
What are some benifits of valconos such as benifits to agiculture, torisum, geothermal power and any others you can think of
Answer by Will To agriculture: Volcanic soil is extremely fertile and will yield a very good harvest.
Tourism is simple, people are drawn to volcanoes for whatever reason.
Geothermal energy is another easy one. The geothermal vents create a lot of heat and pressure, by controlling the release of this pressure we can have a long term source of energy. Imagine all the power of an eruption, but over years instead of all at once.
Question by Tasswon: In your opinion what is the most efficient energy alternative?
K Im doing a survey to see what the most efficient energy alternative is. The choices for the survery are water power, wind power, geothermal power, nuclear power, biomass power, or solar power.
*Note if you can, give reasons why this is the best one
Answer by Jonathan Miller I believe that water power is superior
Can be stored
High efficiency (water is used to turn a turbine to generate electricity)
High concentrations able to provide a reasonable amount of homes
Expensive but tends to pay off extremely fast
handful of suitable locations
slows river and effects wildlife
Can be used anywhere
Can’t be stored naturally
expensive to produce, takes forever to pay off
dependent on weather
Exhaust Steam can be used for heating
Provides a reasonable amount of electricity
Handful of suitable locations
Possible harmful effects can occur like molten iron core hardening or earthquakes. Molten Iron core solidifying will assuredly end all life on earth.
dependent on weather
low energy concentration
repairs are difficult, damage frequent
harmful to birds
Question by : What locations and sources are best for Geothermal Energy conversion plants?
If geothermal energy is the wave of the future for helping to solve most if not all the energy needs of the world.. where and what kind of formations around the world would allow for these?
It is just a very simple question to answer as it is to ask.. no need for the scarcasm
Answer by John P Breaking news the Earth is round. Really it is. We also know how to “Drill baby drill.” The Kola Superdeep Borehole
Here is a brief synopsis of the depths of each layer (in kilometers): 0- 40 Crust
40- 400 Upper mantle
400- 650 Transition region
650-2700 Lower mantle
2700-2890 D” layer
2890-5150 Outer core
5150-6378 Inner core

www.ntv.co.ke Kenya is expected to derive 2200 megawatts of electricity from geothermal power over the next decade. The Chief Executive Officer of the Geothermal Development Company Chief Executive, Dr. Silas Simiyu says the company plans to drill 560 geothermal steam wells over the next 10 years in order to meet that target. NTVs Alex Mwangi now gives us a glimpse of the vast untapped potential for energy that is sitting within the countrys borders. Video Rating: 5 / 5
Kenya is expanding plans to become one of the world’s top geothermal power producers with the start of explorations at a site called Menengai. The government is also aiming to make geothermal Kenya’s main power source. Cathy Majtenyi reports from Menengai. Video Rating: 5 / 5
Central America is sitting on a green energy bank in the form of its active volcanoes. The potential for tapping into geothermal power in Guatemala, for example, is enormous, and the government there is offering tax breaks and other incentives for private investors Central America sits above shifting tectonic plates in the Pacific basin, and this often results in earthquakes and volcanic eruptions. But it also provides a potential source of unlimited green energy in the form of geothermal power.Guatemala’s Pacaya volcano broods quietly today but it’s still active, erupting only months ago and providing a spectacular demonstration of the power that Guatemala’s government hopes can be tapped for practical use. [Romeo Rodriguez, Guatemalan Minister of Energy & Mines]: “Guatemala has an important potential for geothermal power because it’s located in a volcanic area. We are above three shifting tectonic plates; we have 34 volcanoes. We estimate we have the potential to produce up to 1000 Megawatts, to exploit in the use of electrical energy and other uses.” Some 1640 feet (500 meters) below the summit of Pacaya, pipes carrying steam and water at 347 degrees Fahrenheit (175 degrees Celsius) snake across the mountainside to one of two geothermal plants currently operating in the country. Run by Israeli-owned Ormat Technologies Inc, the plant harnesses energy from water heated by chambers filled with molten rock deep beneath the ground. Geothermal power plants, while expensive …
