What is Geothermal and tidal energy.?

Question

What is Geothermal and tidal energy. Also compare and contrast Nuclear fission and
fusion.

Answer 1

Geothermal power is energy generated by heat stored beneath the Earth's surface. Geothermal power supplies 0.416% of the world's energy.[1] Geothermal comes from the Greek words geo, meaning earth, and therme, meaning heat. Prince Piero Ginori Conti tested the first geothermal power plant on 4 July 1904, at the Larderello dry steam field in Italy.[2] The largest group of geothermal power plants in the world is located in The Geysers, a geothermal field in California.[3]


Tidal power, sometimes called tidal energy, is a form of hydropower that exploits the rise and fall in sea levels due to the tides, or the movement of water caused by tidal currents. Although not yet widely used, tidal power has potential for future electricity generation and is more predictable than wind energy and solar power. In Europe, tide mills have been used for over a thousand years, mainly for grinding grains.

Tidal power can be classified into two types:

Barrages make use of the potential energy from the difference in height (or head) between high and low tides, and their use is better established. These suffer from the dual problems of very high civil infrastructure costs and environmental issues.
Tidal stream systems make use of the kinetic energy from the moving water currents to power turbines, in a similar way to wind mills use moving air. This method is gaining in popularity because of the lower cost and lower ecological impact.

Nuclear fission is the splitting of the nucleus of an atom into parts (lighter nuclei) often producing photons (in the form of gamma rays), free neutrons and other subatomic particles as by-products. Fission of heavy elements is an exothermic reaction which can release large amounts of energy both as electromagnetic radiation and as kinetic energy of the fragments (heating the bulk material where fission takes place). Fission is a form of elemental transmutation because the resulting fragments are not the same element as the original atom.

In physics and nuclear chemistry, nuclear fusion is the process by which multiple atomic particles join together to form a heavier nucleus. It is accompanied by the release or absorption of energy. Iron and nickel nuclei have the largest binding energies per nucleon of all nuclei and therefore are the most stable. The fusion of two nuclei lighter than iron or nickel generally releases energy while the fusion of nuclei heavier than iron or nickel absorbs energy; vice-versa for the reverse process, nuclear fission.

Answer 2

Geothermal energy is heat extracted from the natural sub-surface structure of the Earth. Tidal energy harnesses the gravitational pull of the moon on the oceans, as they rise and fall. Nuclear fusion is the source of nuclear power we currently utilise, but fission is still the stuff of research. It will be the "clean" option, if it can be achieved

Answer 3

Geo-thermal potential is the warmth potential from under the floor of earth; usually carry interior the variety of boiling water or steam. that's then makes use of to generate electrical energy. Tidal potential is transferable the potential of shifting water between severe and occasional tides and utilising that flow to create electrical energy. they're the two spotless and eco-friendly sorts of potential and supply off no carbon dioxide or different volatile byproducts.

Answer 4

is this for homework? do a google search and research it on your own. thats called learning

Answer 5

???????????????????????????????????????????????????????????????????????? I no like homework
