How giant ''water batteries'' could make green power reliable
The machines that turn Tennessee''s Raccoon Mountain into one of the world''s largest energy storage devices—in effect, a battery that can power a medium-size city—are hidden in a cathedral-size cavern deep inside the mountain. But what enables the mountain to store all that energy is plain in an aerial photo.

Solar Energy
Solar energy is any type of energy generated by the sun. Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun''s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of …

Energy Storage
The storing of electricity typically occurs in chemical (e.g., lead acid batteries or lithium-ion batteries, to name just two of the best known) or mechanical means (e.g., pumped hydro storage). Thermal energy storage systems can be as simple as hot-water tanks, but more advanced technologies can store energy more densely (e.g., molten salts ...
