Answer 1

Fusion

Answer 2

They say that our world is the exact distance from the Sun. A
little closer, and we'd burn up. A little farther, and we'd freeze.
A Buddhist priest said that the Sun is not hot enough to heat
the Earth.
In the upper atmosphere, and in space, it's cold! It's just that
there are certain properties in the Sun, (rays), that combine with
certain properties in the Earth,( atmosphere), and that creates
temperature.
Without the lifegiving aspects of the Sun, human life could not exist. I heard that Higher Intelligences created a field of
some sorts years ago, to protect us from a destructive blast
of solar energy.

Answer 3

The Sun's energy output (3.86e33 ergs/second or 386 billion billion megawatts) is produced by nuclear fusion reactions. Each second about 700,000,000 tons of hydrogen are converted to about 695,000,000 tons of helium and 5,000,000 tons (=3.86e33 ergs) of energy in the form of gamma rays. As it travels out toward the surface, the energy is continuously absorbed and re-emitted at lower and lower temperatures so that by the time it reaches the surface, it is primarily visible light. For the last 20% of the way to the surface the energy is carried more by convection than by radiation.

Answer 4

This is one of the best questions I have ever seen. Looking at all the answers we are getting. People are throwing everything they got to answer all the possble things related to the words "sun" and "energy".

This is better than doing google search.

Answer 5

yes the sun has a great deal of energy...is is the reason for all seasons along with the tilt of the earth.. is life wonderful on our beautiful planet

Answer 6

Solar power is the technology of obtaining usable energy from the light of the Sun. Solar energy has been used in many traditional technologies for centuries and has come into widespread use where other power supplies are absent, such as in remote locations and in space. Its use is spreading as the environmental costs and limited supply of other power sources such as fossil fuels are realized.
The rate at which solar radiation reaches a unit of area in space in the region of the Earth's orbit is 1,366 W/m², as measured upon a surface normal (at a right angle) to the Sun. This number is referred to as the solar constant.[1] The atmosphere reflects 6% and absorbs 16% of incoming radiation resulting in a peak power at sea level of 1,020 W/m² . [2] [3] Average cloud cover reduces incoming radiation by 20% through reflection and 16% through absorption.[4] The image on the right shows the average solar power available on the surface in W/m² calculated from satellite cloud data averaged over three years from 1991 to 1993 (24 hours a day). For example, in North America the average power of the solar radiation lies somewhere between 125 and 375 W/m², between 3 and 9 kWh/m²/day. [5]

It should be noted that this is the maximum available power, and not the power delivered by solar power technology. For example, photovoltaic panels currently have an efficiency of ca. 15% and, hence, a solar panel delivers 19 to 56 W/m² or 0.45-1.35 kWh/m²/day (annual day and night average).[citation needed] The dark disks in the image on the right are an example for the land areas that, if covered with solar panels, would produce slightly more energy in the form of electricity than the total primary energy supply in 2003. [6] That is, solar cells with an assumed 8% efficiency installed in these areas would deliver a bit more energy in the form of electricity than what is currently available from oil, gas, hydropower, nuclear power, etc. combined.

It should also be noted that a recent concern is that of Global dimming, an effect of pollution that is allowing less and less sunlight to reach the Earth's surface. It is intricately linked with pollution particles and Global warming, and is mostly of concern for issues of Global climate change, but is also of concern to proponents of Solar Power due to the existing and potential future decreases in available Solar Energy. The order of magnitude is about 10% less solar energy available at sea level, mostly due to more intense cloud reflections back into outer space.[citation needed] That is, the clouds are whiter and brighter because the pollution dust serves as a vapor-liquid phase change initiation site and generates clouds where otherwise there would be a moisture filled but otherwise clear sky.

After passing through the Earth's atmosphere, most of the sun's energy is in the form of visible and Infrared radiations. Plants use solar energy to create chemical energy through photosynthesis. Humans regularly use this energy burning wood or fossil fuels, or when simply eating the plants.

Answer 7

yes, the sun has energy

Answer 8

Fusion. Two Hydrogen atoms smash together and make one Helium atom. Energy is released (lots).

Answer 9

The sun is hot. Scientists are checking it out.
