Best answer


The Sun produces a large amount of energy by combining very light elements such ashydrogen to heavier elements such as helium and then lithium, oxygen, carbon, right up to iron. They combine because, once you get the nuclei sufficiently close together, there is a very strong attractive force called the nuclear force which holds them together.

  • Why do we get energy from the Sun?

  • All those systems need power, and that power comes from the sun. The sun is an enormous nuclear power source — through complex reactions, it transforms hydrogen into helium, releasing light and heat. Because of these reactions, every square meter of our planet’s surface gets about 342 Watts of energy from the sun every year.

  • What is the power of the Sun?

  • The Power of the Sun. The sun is the closest star to Earth. Even at a distance of 150 million kilometers (93 million miles), its gravitational pull holds the planet in orbit. It radiate s light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow.

  • How much energy does the Sun produce per year?

  • The sun is an enormous nuclear power source — through complex reactions, it transforms hydrogen into helium, releasing light and heat. Because of these reactions, every square meter of our planet’s surface gets about 342 Watts of energy from the sun every year.

  • What is the importance of the Sun in our daily life?

  • The sun’s energy makes life possible on earth. The heat from the sun creates weather and winds. Its energy can be used to run machines yet most of the sun’s energy is lost in space.
