The energy that powers the sun comes from proton fusion deep within the star's core. The extreme temperature and pressure rips atoms apart, allowing freed protons to combine first into isotopes of hydrogen and then into ... More »

Wind energy is created when moving air causes a wind turbine to rotate, powering a motor that generates electricity. The energy of the wind itself derives from differential heating of the air by the sun and the rotation ... More »

In 1876, William Grylls Adams and Richard Day produced a small amount of electricity by exposing selenium to light. This marked the first time someone was able to convert light into electricity without the aid of heat or... More » Science Astronomy Our Sun

Solar energy emerges when light energy from the sun strikes a silicon solar panel to produce an electrical current. The silicon in the solar panels can transform light energy into electricity because the movement of elec... More » Science Chemistry

Nuclear fusion takes place in the sun's core. The core is where the temperature of the sun is hot enough for nuclear fusion to take place. More »

Glucose is formed through photosynthesis, which is a process performed by plants with energy from the sun. The synthesis process in glucose is performed in chloroplasts in the plant leaves. More »

Nuclear fusion plays a vital role in the continuance of life on Earth because it is the means of energy production employed the sun. If the sun was unable to fuse lighter elements into heavier elements through the thermo... More »
