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.
The energy density of Uranium is 2,715,385 greater than an equal amount of 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.
The amount of the sun's energy that reaches Earth at a given time and place depends on factors such as the angle of incidence, atmospheric conditions, and geographic location. On average, about 1,366 watts per square meter of solar energy reaches the top of Earth's atmosphere, but not all of this energy reaches the surface due to absorption and scattering.
Losses are due to inefficencies of the motor, and friction on moving parts.
The total amount of energy produced by a system when the energy times time is calculated together is known as power. Power is the rate at which energy is transferred or converted.
the amount of energy is double in lipids as compared to carbohydrtes
it contains the least amount of the total energy.
False. The amount of energy produced for each kilogram of uranium is significantly higher than the amount of energy from a kilogram of coal. Uranium has a much higher energy density compared to coal, making it a more efficient and powerful source of energy.
When energy changes forms, it is not always produced. In fact, energy is conserved in a system, meaning it can neither be created nor destroyed. So, when it changes forms, the total amount of energy remains constant.
it contains the least amount of the total energy.
