No, the Earth does not receive 100% of the Sun's energy. In fact, only a very small fraction of the Sun's total energy output reaches Earth. This is because the Sun's energy is emitted in all directions, and only a small portion of it travels in the direction of Earth. Additionally, some of the Sun's energy is absorbed by the Earth's atmosphere and reflected back into space.

The type of radiation that enters the Earth's atmosphere is mostly visible light, but it also includes ultraviolet (UV) and infrared (IR) radiation. UV radiation is the shortest wavelength and most energetic type of radiation, while IR radiation has the longest wavelength and least energy.

The Earth's atmosphere absorbs different types of radiation in different ways. For example, ozone in the stratosphere absorbs most of the UV radiation, while water vapor in the troposphere absorbs most of the IR radiation. The remaining radiation reaches the Earth's surface, where it can be absorbed by the land, water, and vegetation.

Here is a table showing the different types of radiation that enter the Earth's atmosphere and how much of each type is absorbed:

The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth's surface while around 30% is reflected back to space and does not heat the surface. Nearly half of it is absorbed while passing through the atmosphere and the rest reaches the earth's surface. So, only 0.00000005% of sun's total energy is received by the earth. All of the energy the sun releases does not reach Earth. One one-billionth of the Sun's total energy output actually reaches the Earth. Of all the energy that does reach Earth, slightly less than 34 percent is reflected back to space by clouds. The atmosphere allows about half of the Sun's heat energy (50%) to reach Earth's surface. About a third of the Sun's energy (30%) is reflected back into space. The rest of the Sun's energy (20%) is absorbed by greenhouse gases in the atmosphere, like carbon dioxide, water vapor, and methane. As the star for nine planets, a multitude of asteroids, comets and other celestial objects, the Sun contains more than 99 percent of the entire mass in the solar system. Of all of the solar energy reaching the Earth, about 30% is reflected back into space from the atmosphere, clouds, and surface of the Earth. Another 23% of the energy is absorbed by the water vapor, clouds, and dust in the atmosphere, where it is converted into heat. Nuclear fusion is what happens in the Sun – it's the combining of light elements into heavier elements to produce energy. The Sun produces a large amount of energy by combining very light elements such as hydrogen to heavier elements such as helium and then lithium, oxygen, carbon, right up to iron. The core of the sun is the region that extends from the center to about 20–25% of the solar radius. It is here, in the core, where energy is produced by hydrogen atoms (H) being converted into nuclei of helium (He). The sun does not run out of oxygen for the simple fact that it does not use oxygen to burn. The burning of the sun is not chemical combustion. It is nuclear fusion. Without the Sun, Earth's land, water, and air would all be frozen solid! Life on Earth would cease to exist. That's because almost all living things rely on the steady light and heat of the Sun. The Sun's heat makes liquid water on our planet possible. Larger aerosol particles in the atmosphere interact with and absorb some of the radiation, causing the atmosphere to warm. The heat generated by this absorption is emitted as long wave infrared radiation, some of which radiates out into space. Sunlight, shortwave radiation, passes through the atmosphere. Most of Earth's energy comes from the Sun. Shortwave solar radiation that's absorbed by Earth's surface or atmosphere is re-radiated it as long wave, infrared radiation, as heat. Earth's surface and atmosphere absorbs solar radiation and re-radiates it as long wave radiation. We feel this long wave radiation as heat. Energy radiated from Earth's surface as heat, or infrared radiation, is absorbed and re-radiated by greenhouse gases, impeding the loss of heat from our atmosphere to space. Atmospheric radiation is the flow of electromagnetic energy between the sun and the Earth's surface as it is influenced by clouds, aerosols, and gases in the Earth's atmosphere. It includes both solar radiation (sunlight) and long-wave (thermal) radiation.
