The extreme temperature and pressure near the center of the Sun is enough to cause the fusion of the bare nuclei found there. The primary reaction in the Sun is hydrogen fusing to helium. This releases energy by the annihilation of some of the mass of the two atoms. As helium builds up in the core, these atoms are also fused into heavier elements. Nucleosynthesis continues to the production of iron, whose fusion does not release any net energy. The s-process (neutron capture) can form atoms up to bismuth, but again does not release energy.

∙ 14y agoIn the Sun, almost all of the fusion energy is released by the fusion of hydrogen into helium. The process, which requires high density and temperature, produces energy through the loss of mass. Through a three-step process (each creating energy), a pair of hydrogen atoms combine to form a single helium atom.
The energy is released as gamma rays (photons) and neutrinos. Eventually the energy is transferred from the core to the outer layers of the sun, where it is released as solar radiation.
It is this radiated energy that illuminates and heats the Earth.

∙ 13y agoNuclear fusion involves the combining (fusion) of two relatively light elements into one slightly heavier element. In the case of the Sun, the primary reaction is the fusion of hydrogen (four protons) into helium (two protons and two neutrons). The energy comes from the fact that the residual binding energy required to sustain helium is less than the energy required to sustain hydrogen, so this energy is released.
It is not a lot of energy per reaction, about 4.2 x 10-12 joules per reaction, but there are a lot of concurrent reactions, estimates being around 9.2 x 1037reactions per second, hence there is a lot of energy being released, about 3.846 x 1026 joules per second, or about 9.2 x 1010 megatons of TNT per second. Think about that: The largest H-Bomb ever detonated was around 50 megatons - The former USSR's Tsar Bomba in 1961 - Inconsequential in comparison with the Sun!

Is geothermal energy affected by solar energy?
Since geothermal energy comes from underneath the earth you would say no. But since there is water flowing to from the the wells that produce the geothermal energy and solar energy (heat from the sun) can change water temperature, it can.
What source of energy powers the phenomena that occur between Earth's weather and climate?
sun is the primary energy source that drives all weather events
What is the difference between solar energy and wind energy?
The difference between solar energy and wind energy is that solar energy comes from the sun and is in the form of waves. However they are both renewable energy resources.
What are some alternative sources of energy for the sun?
Solar panelsTrap heat energy from the sun.photosynthesisPlants use the suns energy to make food and oxygen.EvaporationSuns heat evaporates water to form clouds and rain.WeatherSuns heat stirs up the atmosphere causing wind and waves.Direct HeatingSome animals use the heat of the sun to activate them.photocellsConvert light to electricity.
Sunlight is what type of resource?
Sunlight is a type of renewable resource, because every day, the sun shines. It makes heat and light energy. Sun energy is also called solar energy. Electricity can be made from solar energy
What types of energy does the sun produce us with?
Solar energy!
What plant organelle produce solar energy to produce chemical energy for surviving?
No plant organelle produces solar energy. Only the sun produces solar energy.
Is it possible on Philippines to use solar thermal energy to produce electricity?
Where is the sun's solar energy production.
How is solar energy produce and where is it produce?
it is produced by the sun. It is mostly produced in Canada.
Can electricity make solar energy?
No. Solar and electric are two different types of energy. The only thing that can produce solar energy is the Sun.
Which uses energy directly from the sun to produce electricity?
solar power
How is solar energy recovered?
Solar energy is recovered by using solar panels. The solar cells on the solar panels use the energy from the sun to produce the electricity used for everyday life.
How is solar energy transferred?
Solar energy is radiation that comes from the sun. It can generate electricity and produce heat. They convert solar radiation into electricity.
What two types of energy does the sun produce?
Light Energy and Solar Energy are all a part produced by the sun.
Benifits of solar energy?
The benefits are that it is free as you produce solar energy from the sun, it is environmental friendly as you do not burn, gas, coal or fuel to produce it, and if you produce extra energy you can feed this back in the national grid and get paid for it
How is the sun's energy solar energy?
the suns energy is solar energy because sun means solar so solar energy is from the sun
Harnessing the sun's energy to produce heat or electricity is what?
non-polluting
