We'll assume you mean lightning.
From the sun.
The sun heats up water, causing water molecules to evaporate and make the atmosphere more humid. And makes the air hot, so it rises. As it rises the pressure drops and the water vapour condenses out as rain drops. As the drops fall they pick up a static electricity charge which moves electrons from the cloud to the earth.
So the earth becomes negatively charged and the cloud becomes positively charged.
Now and then, a big spark (lightning) equalises the static charges.
The energy is solar energy.
This is from Wikipedia article on light:
There are many sources of light. The most common light sources are thermal: a body at a given temperature emits a characteristic spectrum of black-body radiation. Examples include sunlight (the radiation emitted by the chromosphere of the Sun at around 6,000 K peaks in the visible region of the electromagnetic spectrum), incandescent light bulbs (which emit only around 10% of their energy as visible light and the remainder as infrared), and glowing solid particles in flames. The peak of the blackbody spectrum is in the infrared for relatively cool objects like human beings. As the temperature increases, the peak shifts to shorter wavelengths, producing first a red glow, then a white one, and finally a blue color as the peak moves out of the visible part of the spectrum and into the ultraviolet. These colors can be seen when metal is heated to "red hot" or "white hot". The blue color is most commonly seen in a gas flame or a welder's torch. Atoms emit and absorb light at characteristic energies. This produces "emission lines" in the spectrum of each atom. Emission can be spontaneous, as in light-emitting diodes, gas discharge lamps (such as neon lamps and neon signs, Mercury-vapor lamps, etc.), and flames (light from the hot gas itself-so, for example, sodium in a gas flame emits characteristic yellow light). Emission can also be stimulated, as in a laser or a microwave maser. Deceleration of a free charged particle, such as an electron, can produce visible radiation: cyclotron radiation, synchrotron radiation, and bremsstrahlung radiation are all examples of this. Particles moving through a medium faster than the speed of light in that medium can produce visible Cherenkov radiation. Certain chemicals produce visible radiation by chemoluminescence. In living things, this process is called bioluminescence. For example, fireflies produce light by this means, and boats moving through water can disturb plankton which produce a glowing wake. Certain substances produce light when they are illuminated by more energetic radiation, a process known as fluorescence. This is used in fluorescent lights. Some substances emit light slowly after excitation by more energetic radiation. This is known as phosphorescence. Phosphorescent materials can also be excited by bombarding them with subatomic particles. Cathodoluminescence is one example of this. This mechanism is used in cathode ray tube televisions.
the sun wich might i add come from the reaction of 2 atoms together making nuclear fusion.
light energy
The useful energy that comes out is light energy. Heat energy is also produced but is not useful
It comes from light. Light energy is absorbed
Radiant energy comes from the sun.
Light comes in discrete packets called photons. Each photon has energy E = h*frequency. h is called Planck's constant and is ~6.626e-34 Js
light energy
The useful energy that comes out is light energy. Heat energy is also produced but is not useful
light energy is a source that comes from the electricity
Very simple chemical energy
solar energy is the energy that comes from the sun in the form of heat or light.
It comes from light. Light energy is absorbed
Radiant energy comes from the sun.
Natural light comes from sun due to fusion energy in sun. Artificial light either comes directly from fossil fuels or comes from electricity generated by fossil fuels, renewable energy, and/or nuclear energy.
It comes from the Chemical Energy.
