Photovoltaic Cells, Solar Power, and LEDs

Most of the world’s energy can go back to our sun. Every day we are heated by its electromagnetic rays, and plants use the sun’s energy to make sugars and ultimately proteins and other good things to eat. Fossil fuels were also once made from these plant and other organisms that relied on the sun’s…

Thermodynamics and Thermal Energy

Thermodynamics is the study of how energy moves and changes form, usually by way of heat, as suggested by the components of its name: thermo-dynamics. Its laws and equations help to predict what could happen in various situations, based on the temperature, pressure, materials, and shape of a system.

Thermodynamics tells…

Forms of Energy: Motion, Heat, Light, Sound

energy_forms_pie-chart

Energy comes in two basic forms: potential and kinetic. Potential Energy is any type of stored energy; it isn’t shown through movement. Potential energy can be chemical, nuclear, gravitational, or mechanical. Kinetic Energy is the energy of movements: the motion of objects (from people to planets), the vibrations of atoms by sound waves or in thermal energy (heat), the electromagnetic energy of the movements of light waves, and the motion of electrons in electricity.

Salt Domes

Entrance to a German salt dome mine

Salt domes are massive underground salt deposits. Mushroom-shaped and thousands of feet thick, they form where shallows seas once stood. They built up over tens of thousands of years as saltwater flooded these former marine basins, then evaporated.
