In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed
A wind turbine, or alternatively referred to as a wind energy converter, is a device that converts the wind's kinetic energy into electrical energy.
Wind turbines are manufactured in a wide range of vertical and horizontal axis.
Write down the advantages and disadvantages of Wind turbines.
Konpultsioak portaera errepikakorrak edo errituzkoak dira
pertsonak argi pentsatzeko, bere emozioak kontrolatzeko, erabakiak hartzeko edo besteekin harremanak izateko duen gaitasunari erasaten dio
: asaldura horrek gorputz osoari eta gogo-aldarteari eragiten die
asaldura horren ezaugarriak arretarik eza, hiperaktibotasuna eta oldarkortasuna dira
emozio-egoera desatsegina da
Hydrogen fuel is a zero-emission fuel burned with oxygen.
It can be used in fuel cells or internal combustion engines.
Name the advantages and disadvantages of Hydrogen fuel.
There are many different types of energy, which all fall into two primary forms – kinetic and potential.
Energy can transform from one type to another, but it can never be destroyed or created.
Gravitational energy is a form of potential energy.
It is energy associated with gravity or gravitational force, in other words, the energy held by an object when it is in a high position compared to a lower position.
Give examples.
Electrical energy is the movement of electrons, the tiny particles that make up atoms, along with protons and neutrons.
Electrons that move through a wire are called electricity.
Give another example of electrical energy.
Energy storage is the capture of energy produced at one time for use at a later time. A device that stores energy is generally called an accumulator or battery.
Thermal energy storage is achieved with widely differing technologies.
Depending on the specific technology, it allows excess thermal energy to be stored and used hours, days, months later, at scales ranging from the individual process, to building or town.
What are 3 types of thermal energy?
The battery acquires its charged condition either by recharging or in the manufacturing of the unit.
During discharge, the chemical on the anode releases electrons, and ions in the electrolyte undergo an oxidation reaction.
Name the particular compounds in which energy is stored:
Flywheel energy storage (FES) works by accelerating a rotor to a very high speed and maintaining the energy in the system as rotational energy.
Write down the main components of a typical flywheel.
