# On earth, solar energy is most intense at

The equator

## What is the intensity of solar energy?

The Solar Constant. The Sun is considered to produces a constant amount of energy. At the surface of the Sun the intensity of the solar radiation is about 6.33×107 W/m2 (note that this is a power, in watts, per unit area in meters).

## What are the reasons for variation in the amount of solar energy reaching Earth surface?

Cloud cover, air pollution, latitude of a location, and the time of the year can all cause variations in solar radiance at the Earth’s surface. The amount of energy reaching the surface of the Earth every hour is greater than the amount of energy used by the Earth’s population over an entire year.

## How much solar energy strikes the earth?

A total of 173,000 terawatts (trillions of watts) of solar energy strikes the Earth continuously. That’s more than 10,000 times the world’s total energy use. And that energy is completely renewable — at least, for the lifetime of the sun.

## Which part of the Earth receives most?

The equator is the part of the earth that absorbs most of the sun’s rays as the sunlight reaches the Earth at a perpendicular (90 degree) angle.

## What is CSP in solar power?

Concentrating Solar Power 101

CSP technologies use mirrors to reflect and concentrate sunlight onto receivers that collect solar energy and convert it to heat. Thermal energy can then be used to produce electricity via a turbine or heat engine driving a generator.

## What are 4 types of radiation from the sun?

Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.

## How much sunlight does Earth get?

Averaged over the entire planet, the amount of sunlight arriving at the top of Earth’s atmosphere is only one-fourth of the total solar irradiance, or approximately 340 watts per square meter.

Definition of ‘radioactive’ according to Google: “emitting or relating to the emission of ionizing radiation or particles.” So, the sun emits ionizing particles, and is therefore radioactive. … The sun is radioactive in many ways. First, the light you see from the sun is a form of radiation.

## How much solar energy does the earth receive in one day?

Most of the world’s population live in areas with insolation levels of 150–300 watts/m², or 3.5–7.0 kWh/m² per day. Solar radiation is absorbed by the Earth’s land surface, oceans – which cover about 71% of the globe – and atmosphere.

## Where on earth is the maximum insolation?

The sun is closest to the earth in January (winter in the northern hemisphere), so that the maximum solar insolation received in the southern hemisphere is greater than that received in the northern hemisphere. At the equinoxes, solar insolation is at a maximum at the equator and is zero at the poles.

## How much solar energy hits the Earth per day?

A total of 173,000 terawatts (trillions of watts) of solar energy strikes the Earth continuously. That’s more than 10,000 times the world’s total energy use. And that energy is completely renewable — at least, for the lifetime of the sun.

## Does the sun make noise?

The surface of the Sun produces sound waves because the surface is convecting and this produces pressure waves that travel into the inner corona. … But yes, the surface does produce sound waves, but they have very low wavelengths measures in hundreds of miles!

## Can the sun power the earth?

The Sun releases an estimated 384.6 yotta watts (3.846×1026 watts) of energy in the form of light and other forms of radiation. We are able to survive on Earth because the energy is spread over the area of a sphere with a radius of approximately 93,000,000 miles.
