It's going to be difficult to tell you more than I know, but I'll give it my best shot.\n\nThe sun is big and bright and hot.  It is a giant fusion reactor creating energy by fusing atoms of matter together.  The energy is transmitted out into space as photons of light.\n\nIt is a medium sized yellow star which began making energy about 4 billion years ago and is estimated to have about 5 billion years left before its fuel begins to run out.

It would be heat and sunlight- A cycle means that a substance or energy will eventually return to its origin.  Sunlight generates heat and chemical energy on the Earth, but is non-cyclic, in other words, you have to have a constant infusion of it all the time, it doesnt recycle.  The majority of the energy of sunlight is lost as heat, out of our atmosphere into space, never to enter the cycle again. So the flow would be sunlight in, some chemical use and some heat absorption, and eventually all the energy is lost as heat out.

Ok you need a bowl of water and the sun. The energy is trapped (at least temporarily) in the water, as heat.

the light energy is obvious-sun\n\nbut others like thermal -carbon compunds formed over millions of years using light, gravity etc may be even big bang energy(just a blind guess)\n\nwind energy-i guess its temperature diff created by sun\n\nnuclear energy-probably formed during formation of universe & soler system

In the surface of the sun, the hydrogen and helium are get reacted and generate the heat energy. This power is a main reason to sun is very hot. Due to cenre of gravity all bodies get link with sun and rotate.

The energy in the sun's core comes from fusing hydrogen into helium.  Most of the energy emerges in the form of high-speed particles and gamma rays, neither of which can go very far in the dense, hot plasma.  This energy moves by a process of conduction through the core, until it reaches less dense regions of the sun, where a process of convection moves the energy through the material.  \n\nOnly in the upper regions of the sun's surface does the density reach a point where the energy moves by the more familiar (to us) radiation.  The time for energy to go from the core of the sun to its surface is about a quarter of a million years.  \n\nThus, almost all the energy we see is a display of the activity in the Sun's core a quarter of a million years ago.  But there IS a way to jump the queue and see what is happening in the core.\n\nEvery fusion reaction in the Sun produces neutrinos, mass-less particles that barely interact with the surrounding matter.  These fly off unimpeded by the material around them, so, like the light from the photosphere, they move at the speed of light, and reach us eight minutes later after crossing the distance between us and the sun.\n\nIt takes a lot of effort to capture a neutrino, but they tell us a lot about what is happening in the core of the sun right now, while all we see on its surface is a sign of its remote past.  Since we're not finding as many neutrinos as we think we should, we're wondering if our knowledge of physics needs improving, or if the Sun is, in fact,a more variable star than we'd like to think.

The sun is the original source of energy. This energy is used by green plants that are situated at the beginning of food chains as they are consumed by herbivores, also known as primary consumers. Green plants are known as autotrophs or producers only because they are at the start of food chains. You never learn of a food chain that begins with an animal.

The USA creates more energy than any other country in the world.  When energy is created, especially by burning fossil fuels like coal and oil, chemical fumes are released into the air.  These chemicals, especially sulfuric dioxide and nitrogen oxides, combine with water vapor in clouds, and when it rains, the resulting acid is carried back to earth in the raindrops.

the sun doest not use oxygen. it actually follows a method called nuclear fusion, whereby two hydrogen atoms react to form a helium atom. with this, very large amounts of heat and light are produced

The sun operates like all other stars in it uses fusion to create its energy.  The sun is made of hydrogen and when a hydrogen molecule is combined with an oxygen molecule at a highspeed it becomes helium and the excess energy from the two molecules combining gives the sun its heat.  Gravity is working to crush the star and its fusion energy is working to inflate it.  This is what gives the star its spherical shape.

This question could be interpretted two different ways: (1) What drives the sun to produce heat/enegery? and (2) Describe the process of using the solar energy to power modern conventions.\n\nSomebody else already attempted the latter, so I'll go for #1.\n\nThe sun, right now, is fusing hydrogen into helium to produce its energy.  It's been doing this for a long time, and will continue to do so until it runs out of hydrogen.  When this happens, it'll start fusing the helium, and so on.\n\nHope this helps.

The Sun is the most prominent feature in our solar system. It is the largest object and contains approximately 98% of the total solar system mass. One hundred and nine Earths would be required to fit across the Sun's disk, and its interior could hold over 1.3 million Earths. The Sun's outer visible layer is called the photosphere and has a temperature of 6,000°C (11,000°F). This layer has a mottled appearance due to the turbulent eruptions of energy at the surface. \nSolar energy is created deep within the core of the Sun. It is here that the temperature (15,000,000° C; 27,000,000° F) and pressure (340 billion times Earth's air pressure at sea level) is so intense that nuclear reactions take place. This reaction causes four protons or hydrogen nuclei to fuse together to form one alpha particle or helium nucleus. The alpha particle is about .7 percent less massive than the four protons. The difference in mass is expelled as energy and is carried to the surface of the Sun, through a process known as convection, where it is released as light and heat. Energy generated in the Sun's core takes a million years to reach its surface. Every second 700 million tons of hydrogen are converted into helium ashes. In the process 5 million tons of pure energy is released; therefore, as time goes on the Sun is becoming lighter. \n\n \n\nThe chromosphere is above the photosphere. Solar energy passes through this region on its way out from the center of the Sun. Faculae and flares arise in the chromosphere. Faculae are bright luminous hydrogen clouds which form above regions where sunspots are about to form. Flares are bright filaments of hot gas emerging from sunspot regions. Sunspots are dark depressions on the photosphere with a typical temperature of 4,000°C (7,000°F). \n\nThe corona is the outer part of the Sun's atmosphere. It is in this region that prominences appears. Prominences are immense clouds of glowing gas that erupt from the upper chromosphere. The outer region of the corona stretches far into space and consists of particles traveling slowly away from the Sun. The corona can only be seen during total solar eclipses. (See Solar Eclipse Image). \n\nThe Sun appears to have been active for 4.6 billion years and has enough fuel to go on for another five billion years or so. At the end of its life, the Sun will start to fuse helium into heavier elements and begin to swell up, ultimately growing so large that it will swallow the Earth. After a billion years as a red giant, it will suddenly collapse into a white dwarf -- the final end product of a star like ours. It may take a trillion years to cool off completely.

The sun is the earth's largest source of reliable energy.  Plants have green leaves that absorb and trap sunlight and convert that light into chemical energy; namely starches that other animals eat.\n\nThe sunlight is converted to starches by chlorophyll, a green substance in the leaves of green plants.  Carbon dioxide gas molecules (CO2) in our atmosphere is combined into sugar; sugar is combined into starches.  Wood is a form of starch called cellulose.\n\nSecondly, water is "split" (chopped into three pieces) releasing oxygen (gas) by photosynthesis.  So plants provide us oxygen by "splitting" water; and plants provide us sugar by "fixing" carbon dioxide.  We eat the plants or we animals that eat the plants.  This is how we get our energy.\n\nSo, cows are animals that eat grass; in so doing they gather sugar energy and live.  We eat cows, for example.  Or, certain insects eat plants; some fish eat those insects and then we eat the fish...so on and so forth.

Solar Power harnesses the energy of the sun to turn water into high pressure steam. The sun gives panels which heat the water kinetic energy to affect the interaction energy of the water (like how you get a sunburn). The steam rotates a turbine to generate power.
