Electrical energy is caused by moving electric charges called electrons. In power stations, turbines are turned using energy from sources such as heat, wind and moving water. Generators are machines for converting motion energy into electricity.

Electromagnetic induction. Electromagnetic induction is the effect used in a turbine to convert mechanical energy into electricity.

An electric generator converts mechanical energy to electrical energy.

In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft. The force of the fluid on the blades spins/rotates the rotor shaft of a generator. The generator, in turn, converts the mechanical (kinetic) energy of the rotor to electrical energy.

Dynamo

Many devices are used to convert mechanical energy to or from other forms of energy, e.g. an electric motor converts electrical energy to mechanical energy, an electric generator converts mechanical energy into electrical energy and a heat engine converts heat energy to mechanical energy., In physical sciences.

After hundreds of years of observation and experimentation, science has classified energy into two main forms: kinetic energy and potential energy. In addition, potential energy takes several forms of its own.

States of Energy All energy can be in one of two states: potential energy or kinetic energy. Potential energy is stored energy – energy that is ready to go.

The short answer is no. Energy didn’t come “from nothing”. Since the big bang is an observational event horizon, we cannot talk about any events earlier, so one assumes that all the energy and matter has always been contained in your universe. So now, we cannot create energy.

The smallest possible size for anything in the universe is the Planck Length, which is 1.6 x10-35 m across.

Today, we know that atoms do not represent the smallest unit of matter. Particles called quarks and leptons seem to be the fundamental building blocks – but perhaps there is something even smaller. Physicists are still far from understanding why a proton has about 2,000 times more mass than an electron.

A neutrino is a subatomic particle that is very similar to an electron, but has no electrical charge and a very small mass, which might even be zero. Neutrinos are one of the most abundant particles in the universe. Because they have very little interaction with matter, however, they are incredibly difficult to detect.

The ICARUS detector in Gran Sasso, Italy, has confirmed that neutrinos travel no faster than the speed of light. Neutrinos obey nature’s speed limit, according to new results from an Italian experiment.
