Renewable energies are those energies using an energy source or fuel which is considered inexhaustible or can be regenerated at the same rate at which it is consumed.
The classification of renewable energy depends on natural resources exploited. Solar energy
We distinguish two ways of using solar energy:
- Solar thermal energy.
- Solar photovoltaic energy.
The use of solar thermal is to use heat energy obtained from solar radiation to heat a fluid, depending…
After years of neglect of the exclusion zone of the Chernobyl nuclear plant, it may be given a new use as the Ukrainian authorities are considering turning it into a huge solar power plant.
The Chernobyl nuclear power plant suffered the worst nuclear accident in history when in 1985 exploded the core of its reactor No. 4. The severity of the accident along with mismanagement after the accident, generated a lot of contaminated area and consequently, abandoned.
Now, 30 years later, it is considering giving a new utility: it is turn the area into a plant of photovoltaic solar energy,…
A nuclear power plant is a facility for obtaining electrical energy using nuclear energy.
Its operation is similar to that of a thermal power plant or that of a solar thermal plant: from a source of energy thermodynamics is used to obtain heat, with the heat to get steam and with the steam to drive a turbine that will generate electricity.
The difference between the different types of electrical installations is in the energy source: a nuclear power plant uses the heat released in the nuclear fission reactions of certain atoms, in a thermal power station the heat source (thermal…
We define electricity as the form of energy that results from the existence of a potential difference between two points. When these two points are put in contact by means of an electrical conductor we obtain an electric current.
In physics, the electric potential energy, also called electrostatic potential energy, is the potential energy of the electrostatic field. This is an energy that has an electrical charge distribution, and is linked to the force exerted by the field generated by the distribution itself. Together with magnetic energy, the electric potential energy constitutes…
Heat energy is the manifestation of the energy in the form of heat. All materials have atoms that form molecules with constant movement and vibration. This movement of atoms generates a kinetic energy called heat or heat energy.
If we increase the temperature of any element, we increase its heat energy. However, when we increase the heat energy of an element it's not guarantee that its temperature is increased. The temperature is the same during the stage of changes. A good example is heating some water. Little by little we obtain heat…
