Five Little Things You Can Do to Make Your Home More Energy Efficient
An informative article about improving the energy efficiency of a house.
Plant lamps powered by soil nutrients bring electricity to remote areas of Peru
In parts of the world that don’t have steady access to the electricity grid, finding power for essential things like night lighting are an ongoing challenge. While you can burn kerosene in lamps to pr...
The Dirty Secret Behind Electric Cars
As the world tries to reduce greenhouse-gas emissions and combat climate change, policymakers have pinned hopes on electric cars, whose range and convenience are quickly improving. Alongside the boom ...
Germany is turning on its monster stellarator
For more than 60 years, scientists have dreamed of a clean, inexhaustible energy source in the form of nuclear fusion. And they're still dreaming. But thanks to the efforts of the Max Planck Institu...
The World’s Most Powerful Laser Has Just Been Fired In Japan
Scientists in Japan have set the record for the most powerful laser ever fired, producing a 2 petawatt pulse - that’s 2 quadrillion watts - using a device known as the Laser for Fast Ignition Experime...
Energy
Fuel cells may soon generate electrical power for all sorts of devices we use every day. Learn more about fuel cells in this video from HowStuffWorks.
Energy
In physics, energy is a property of objects, transferable among them via fundamental interactions, which can be converted into different forms but not created or destroyed. The joule is the SI unit of...

Outline of energy
The following outline is provided as an overview of and topical guide to energy:Energy – in physics, this is an indirectly observed quantity often understood as the ability of a physical system ...
Nuclear power
Nuclear power is the use of nuclear reactors to release nuclear energy, and thereby generate electricity. The term includes nuclear fission, nuclear decay and nuclear fusion. Presently, the nuclear fi...

Characteristic energy
In astrodynamics the characteristic energy () is a measure of the excess specific energy over that required to just barely escape from a massive body. The units are lengthtime, i.e. energy per mass.Ev...
Energy functional
The Energy functional is the total energy of a certain system, as a functional of the system's state.In the energy methods of simulating the dynamics of complex structures, a state of the system is o...
Josephson energy
In superconductivity, the Josephson energy is the potential energy accumulated in the Josephson junction when a supercurrent flows through it. One can think of a Josephson junction as a non-linear ind...
Mechanical energy
In the physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object. The principle of conservation of m...

Threshold energy
In particle physics, the threshold energy for production of a particle is the minimum kinetic energy a pair of traveling particles must have when they collide. The threshold energy is always greater t...
Nuclear fusion
In nuclear physics, nuclear fusion is a nuclear reaction in which two or more atomic nuclei collide at a very high speed and join to form a new type of atomic nucleus. During this process, matter is ...
Forms of energy
In the context of physical sciences, several forms of energy have been identified. These include:Some entries in the above list constitute or comprise others in the list. The list is not necessarily ...
Magnetic energy
Magnetic energy and electric energy are related by Maxwell's equations. The potential energy of a magnet of magnetic moment m in a magnetic field B is defined as the work of magnetic force (actually ...
Equivalent dumping coefficient
An equivalent dumping coefficient is a mathematical coefficient used in the calculation of the energy dispersed when a structure moves. As a civil engineering term, it defines the percent of a cycle o...
Specific energy
Specific energy is energy per unit mass. (It is also sometimes called "energy density," though "energy density" more precisely means energy per unit volume.) It is used to quantify, for example, store...

Helmholtz free energy
In thermodynamics, the Helmholtz free energy is a thermodynamic potential that measures the “useful” work obtainable from a closed thermodynamic system at a constant temperature. The negative of the d...
Zero-point energy
Zero-point energy, also called quantum vacuum zero-point energy, is the lowest possible energy that a quantum mechanical physical system may have; it is the energy of its ground state. All quantum mec...
Radiant energy
In radiometry, radiant energy is the energy of electromagnetic radiation. The SI unit of radiant energy is the joule (J). The quantity of radiant energy may be calculated by integrating radiant flux (...
