How is solar energy produce?

Solar power is generated in two main ways: Photovoltaics (PV) also called solar cells are electronic devices that convert sunlight directly into electricity. … Concentrated solar power (CSP) uses mirrors to concentrate solar rays. These rays heat fluid which creates steam to drive a turbine and generate electricity.

Does the sun produce carbon?

The temperature and pressure in the Sun’s core will soar to 10 times their current values. … When the temperature in the core reaches about 100 million degrees the helium will begin to fuse into carbon by a reaction known as the triple-alpha process because it converts three helium nuclei into one carbon atom.

How are photons created in the sun?

Fusion occurs in the sun’s innermost core when two atoms merge releasing energy and light in the process. Photons of light are first created in the sun’s center. Over tens of thousands of years the photons travel a “drunken walk ” zigzagging their way from atom to atom until they reach the surface.

How the sun produces heat and light?

The core of the sun is so hot and there is so much pressure nuclear fusion takes place: hydrogen is changed to helium. Nuclear fusion creates heat and photons (light). … The amount of solar heat and light is enough to light up Earth’s days and keep our planet warm enough to support life.
