Light is the only energy source that can travel without a medium, so as it travels through empty space there is nothing to divert it and if Newton's law of motion, an object in motion stays in motion, stands true then 100% of the light from the sun should reach the earth. When the light hits the earth most of it is deflected or absorbed by the atmosphere.

Whilst substantially true in itself the first sentence is not correct for 2 reasons.
1) The sun radiates its energy from its entire surface, therefore we receive only that from a small area of its surface.
2) Radiated energy from a point source - in astronomical scales the Sun's diameter is small compared to the distances - is attenuated by spreading as the surface of a sphere of increasing radius, so by an inverse-square law. (Area of a sphere's surface is proportional to radius squared.)
Therefore the flux density reaching us nearly 149 million km from the Sun, will be 1/ 149-squared that of its density only 1 million km from the Sun.
The mean solar energy flux at Earth's distance is 1370W/m^2, but that reaching the ground is far lower.

How does the amount of energy produced by the Sun compared with the amount of energy that reaches Earth from the Sun?
If we assume that the sun emits energy at the same rate in all directions, then the ratio is(4 pi) (distance to the sun)2 / (pi) (earth radius)2 = 2,162,250,000 times as much,or about 93 dB more.
Does solar energy create as much energy as coal?
"Create as much energy" is poorly defined. The amount of energy produced from solar energy will depend on the surface area used for solar panels, the weather, the efficiency of the panels, and for how long it is used. Similarly, the amount of energy produced by a coal power plant would depend on its size, its efficiency (which of course may also vary), and for how long it is used. Please think about what exactly you want to compare.
What process does the sun do to give heat to earth?
The energy of the sun is produced by the process of nuclear fusion, and a portion of this energy reaches the Earth in the form of sunlight, which heats the Earth.
Where is the sun's energy produced?
The Sun's energy is produced in the Sun's core.
What is one energy the reaches earth from the sun?
The energy that reaches the Earth from the sun is known as sunlight.

Compare the energy produced during fission of a uranium atom with the energy produced from combustion of carbon atom from coal?
The energy density of Uranium is 2,715,385 greater than an equal amount of coal

A kitchen blender transforms electrical energy into mechanical energy Why is the amount of mechanical energy produced less than the amount of electrical energy used?
Losses are due to inefficencies of the motor, and friction on moving parts.
The amount of the suns energy that reaches earth at a given time and place is?
Insolation
When energy changes forms energy is always produced?
No, energy is not produced. The total amount of energy doesn't change.
Compare the energy stored in a lipid to the energy stored in a carbohydrate?
the amount of energy is double in lipids as compared to carbohydrtes
How does the level of an energy pyramid compare to the bottom level of that energy pyramid?
it contains the least amount of the total energy.
Is it true or false that the amount of energy produced for each kilogram of uranium is about the same as the amount of energy from a kilogram of coal?
false
What is the amount of energy produced in partial breakdown of glucose?
45
Compare the total amount of energy before and after physical and chemical changes?
Physical Change-- Same amount of energy, but in different form Chemical Change-- Different amount of energy, and in a different form
