i think its hydroggen gas burning

all the energy comes from the sun....plants turn it into a form that is useful to animals...so a carnivore eats a smaller animal who may be an herbivore who feeds exclusively on plants...plants that used photosynthesis to turn solar energy to food!

The energy from the sun that plants use to make their food and to create oxygen..\n\nGravity keeps you from flying off into space.  Come to think of it, keeps the atmosphere from flying off into space.\n\nThe force that keep atomic particles together and not fly into indifidual directions, keeping YOU to gether.

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.

Heat energy.\n\nThere is water (or a water mixture) cooling the core directly.  This water is radioactive.  You then have coils running in the water which have other water (protected from the radiation) coursing through them.  This water gets the heat transfered to it and turns to steam.  The steam runs turbines that turn a magnet core in the center of a copper coil that in turn produces electricity.\n\nHope this answers it for ya, feel free to email me!

Most life on Earth is powered by the Sun. Plants use Photosynthesis to make carbohydrates from the Sun. Animals eat Plants, we eat both plants and animals that eat plants. Therefore indirectly virtually all of our food energy comes from the Sun. Our Brain uses our food energy to operate. Therefore our brain is powered by the Sun.

electrical energy-------> heat + light\ndoes that help?

The Sun is the only "substance" that can produce solar power!\n\nDid you perhaps mean what chemical substances can harness solar power?  Most solar cells are made from semi-conducting materials like Silicon and Germanium.  \n\nHere's some info:

The energy from the sun comes from nuclear fussion: the combining of 2 Hydrogen atoms to make Helium and energy.\nWhen the sun will lose it's fuel (in about 5 Billion years), it will turn into a red giant star.

As taken from the EERE Solar energy basics website:\n\n"Sunlight—solar energy—can be used to generate electricity, provide hot water, and to heat, cool, and light buildings.\n\nPhotovoltaic (solar cell) systems convert sunlight directly into electricity. A solar or PV cell consists of semiconducting material that absorbs the sunlight. The solar energy knocks electrons loose from their atoms, allowing the electrons to flow through the material to produce electricity. PV cells are typically combined into modules that hold about 40 cells. About 10 of these modules are mounted in PV arrays. PV arrays can be used to generate electricity for a single building or, in large numbers, for a power plant. A power plant can also use a concentrating solar power system, which uses the sun's heat to generate electricity. The sunlight is collected and focused with mirrors to create a high-intensity heat source. This heat source produces steam or mechanical power to run a generator that creates electricity."

Sun is the source for light and light is needed and is used by plants for photosynthesis. by photosynthesis plans prepare their own food which helps them to grow and we humans eat plants as well as animals so if we have light then everything is possible....

This is suppose to be common sense by now well unless you're 6 yr old then that's different. So I guess you need read this:\n\nsolar energy, any form of energy radiated by the sun, including light, radio waves, and X rays, although the term usually refers to the visible light of the sun. Solar energy is needed by green plants for the process of photosynthesis, which is the ultimate source of all food. The energy in fossil fuels (e.g., coal and oil) and other organic fuels (e.g., wood) is derived from solar energy. Difficulties with these fuels have led to the invention of devices that directly convert solar energy into usable forms of energy, such as electricity. Solar batteries, which operate on the principle that light falling on photosensitive substances causes a flow of electricity, play an important part in space satellites and, as they become more efficient, are finding increasing use on the earth (see solar cell). Thermoelectric generators convert the heat generated by solar energy directly into electricity (see thermoelectricity). Several projects have produced electricity on a large scale by using the solar energy available in desert areas. In one system, large numbers of solar batteries generate electricity for Coconut Island, off the coast of Australia. In another, oil flows through pipes that are set in reflecting parabolic troughs that can trap the heat from sunlight falling on them. The heat from the oil is then converted into electricity (see power, electric). Heat from the sun is used in air-drying a variety of materials and in producing salt by the evaporation of seawater. Solar heating systems can supply heat and hot water for domestic use; heat collected in special plates on the roof of a house is stored in rocks or water held in a large container. Such systems, however, usually require a conventional heater to supplement them. Solar stoves, which focus the sun's heat directly, are employed in regions where there is much perennial sunlight.\n\nAlso there are tons of info on this on the web just go to Yahoo search or Google and type in Solar Energy. It's not that hard.

Material from the sun's surface, about 75% hydrogen, 24% helium, and 1% everything else

It's from radioctivity and friction.  The gas giants also create more heat than they recieve from the sun.  The sun is nowhere the near the only source of energy in the solar system.

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 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.

Light IS energy...sorry I can only think of one...:(
