Geothermal

Geothermal energy is considered relatively carbon neutral because it releases significantly less carbon dioxide compared to fossil fuels during energy generation. However, there can be some emissions from the drilling and construction processes associated with geothermal power plants.

Geothermal and hydroelectric power both generate electricity from renewable sources. They are clean energy technologies that produce minimal greenhouse gas emissions compared to fossil fuels. Both energy sources rely on natural processes to generate power and are considered sustainable options for the future.

Currently, geothermal energy is gaining popularity as an energy source to cool and heat homes throughout the US. There are many different techniques and methods, but it is basically utilizing the technology of heat pumps drilled into the ground to tap into the more stable temperatures. In winter heat from the earth is transferred to building, while in summer it can transfer heat from the home into the ground (acting much like a refrigerator).

Some potential drawbacks of geothermal energy include high upfront costs for installation, limited geographical availability based on proximity to tectonic plate boundaries, potential subsurface environmental impacts such as induced seismicity or groundwater contamination, and challenges associated with transporting and storing geothermal heat.

Im really not sure of the question but if you are refering to using an electric immersion heater in a thermal store over a ground source heat pump, the immersion heater has a COP of 1 and the ground source heat pump has a COP of 3. So 3 times better.

The amount of electricity produced by a water wheel depends on factors such as the size of the wheel, the flow rate of the water, and the design of the turbine. On average, a small water wheel can generate enough electricity to power a few homes, while larger water wheels can generate enough to power entire communities.

Some disadvantages of thermal energy include high operating costs, greenhouse gas emissions during operation, and the potential for environmental damage if not properly managed. Additionally, thermal energy systems can be limited by geographic location and are not always cost-effective compared to other renewable energy sources.

Yes, an electromagnet can be made out of any material that conducts electricity, not just metals. However, materials like iron, nickel, and cobalt are commonly used due to their high magnetic permeability and ability to be magnetized easily.

It's very effective and efficient. It of course uses the earth's heat for heating a building. Only a small amount of electricity is needed for this, compared to the large amount needed for an electric furnace or baseboard heater. Geothermal is very expensive to install, but will make up for the cost in the savings you will have over a period of several years.

The waste by-products of geothermal energy typically include dissolved minerals and gases brought to the surface along with the geothermal fluid. These by-products may require treatment and disposal to prevent environmental impacts. Additionally, there may be some minor emissions of greenhouse gases during the operation of geothermal power plants.

The benefits of energy production are that the use of fossil fuels are readily available for use and it is a simple process to break these fuels into energy. The risks associated with energy development is that the combustion of these fields lead to pollution which affects the environment.

There are 3 methods which can be used:

1. is flash steam method. Very hot water from underground (360 degrees F) is pumped to the surface where it flashes to steam and drives the turbines.

2. dry steam method uses steam as it comes from the underground source to drive the turbines. It is then force back into the ground.

3. uses the binary cycle. This takes heated water from the ground and runs it through a heat exchanger where it heats a fluid with a lower boiling point. The fluid flashed to steam and drive the turbine.

Kinetic. It's all kinetic (thermal heat energy is actually a form of kinetic energy applied at the molecular level.)

They are located in volcanic areas

There are AGRs at the following: Dungeness B, Hinkley B, Hunterston B, Hartlepool, Heysham 1, Heysham 2, and Torness for a total of 14 reactors.

Most of the magnox reactors are now shut down. I believe Wylfa is the only one still operating. There is also a PWR operating (Sizewell B).

If you are after the thrmodynamic principles, see Wikipedia entry for Rankine Cycle.

Iceland lies on a contructive plate boundary whichs means that the plates are moving away from eachother. this means that there is a lot of tectonic activity which heats the rocks (they are close to the mantle). Water can be heated using this heat. the steam from the heated water can be used to create electricity by driving a turbine with the steam.

This electricity can be used in homes in the same way other countries use electricity from coal. The difference is that coal is finite and the geothermal is not. This means that it is cheap and sustainable, and so it would be silly for Iceland not to use this.

Thermal energy exists under the continent -- as it does under all continents -- and may be the reason why there are sub-glacial lakes miles below the ice sheet that covers 98% of the continent.

Research stations, however, have not installed the technology to capture this natural thermal energy use in their scientific pursuits..

An electrical generator, these can produce AC or DC electric current.

The water is hot because it comes from the earths mantle. If the hot springs is in a volcanic zone like Yellowstone national park, water may be heated by the magma in the volcano near by.

A gas turbine extracts energy from a flow of hot gas produced by combustion of gas or fuel oil in a stream of compressed air. It has an upstream air compressor (radial or axial flow) mechanically coupled to a downstream turbine and a combustion chamber in between. "Gas turbine" may also refer to just the turbine element. Energy is released when compressed air is mixed with fuel and ignited in the combustor. The resulting gases are directed over the turbine's blades, spinning the turbine, and mechanically powering the compressor. Finally, the gases are passed through a nozzle, generating additional thrust by accelerating the hot exhaust gases by expansion back to atmospheric pressure. Energy is extracted in the form of shaft power, compressed air and thrust, in any combination, and used to power aircraft, trains, ships, electrical generators, and even tanks.
