What is energy?

[isawit]

the sun is not an active reactor.

if energy can never leak/vanish into space, why all the fuels we used did not make earth warmer?

if you cut a channel between the ocean and a lake, the water level will be the same. if rained 1 foot into the lake, the water level will be still the same.

if rained 1 inch in the ocean, the lake will be flooded by 1 inch.

the sun's energy/vibrating electrostatic force/radiation stays within the upper atmosphere and moves around the earth. That energy/electrical current stays within the atmosphere and crust and moves westward at 1000 miles per hour at the equator, produces earth magnetic field, causes polar lights.

transforms into matters movement, the wind, clouds, waves, photosynthesis and more.

nothing is moving ?

[isawit]

energy is moving force, not rest force.

all forces are the electrostatic force, gravity and magnetic force are based on electric force.

moving charges, matters, and magnets carry energy.

all free energy is within sunlight, wind, wave, falling water, and fuels.

energy cannot exist without matters to carry it.

[isawit]

sunlight/vibration electric force/ac current is circling the earth westward as earth spins.

that circling energy causes earth's magnetic force, interact with compasses. produces polar lights.

a conducting ring around or parallel the equator should carry dc current.
