DOE Explains...Batteries. Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical ...

Although you use energy as you climb, your body and the boulder also gain energy—potential energy. When the boulder is at the top of the hill, you can let it go so it rolls back down again. It can roll down because it has stored potential energy. In other words, it has the potential to roll down the hill all by itself.

This can be achieved by either traditional internal combustion engines, or by devices called fuel cells. In a fuel cell, hydrogen energy is converted directly into electricity with high efficiency and low power losses. Hydrogen, therefore, is an energy carrier, which is used to move, store, and deliver energy produced from other sources.

Laws of Thermodynamics. Law 1: Energy can neither be created nor destroyed. However, energy can be converted into different forms to provide energy services. For example, a space heater converts electrical energy to heat. Law 2: Heat flows from hot to cold, and there are losses when converting from heat to work.

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
