Question

What is electric energy? How is electricity produced in following:
(a) Hydel electric plant
(b) Wind energy plant
(c) Solar energy plant

Answer 1

Hint:Energy is the quantitative quality that must be supplied to a body or physical system in order to perform work on it or to heat it, according to physics. Energy is a conserved quantity, meaning it may be transformed in form but not generated or destroyed, according to the rule of conservation of energy. The joule is the energy supplied to an item by the effort of moving it a distance of one metre against a force of one newton, as defined by the International System of Units (SI).

Complete answer:
Electrical energy is the energy produced from electron mobility. Electrical energy is a term that is used to describe energy that has been transformed from electric potential energy. This energy is provided via an electrical circuit that delivers a mix of electric current and electric potential. This electric potential energy is no longer electric potential energy once it has been transformed to another sort of energy. Before it is supplied to the end-user, all electrical energy is potential energy. Electrical energy is always referred to as another form of energy once it has been converted from potential energy (heat, light, motion, etc.).

(a) Electrical energy is the energy stored in charged particles. The turbine is moved by the flow of water. The turbine is a machine that transforms kinetic energy into electrical energy. The building of a hydroelectric complex can have a major environmental impact, mostly due to the loss of agricultural land and the displacement of people. They also have an impact on the river's natural ecology, altering habitats and ecosystems, as well as siltation and erosion patterns. While dams can reduce flooding concerns, they also pose the danger of dam failure, which can be disastrous.

(b) Wind speed causes the blades of a windmill to move. A windmill's fan is connected to a turbine. The turbine is a machine that transforms kinetic energy into electrical energy. Wind power, often known as wind energy, is the utilisation of wind turbines to generate mechanical power, which is then used to spin electric generators to generate electricity. When opposed to burning fossil fuels, wind power is a popular sustainable, renewable energy source that has a considerably lower environmental effect.

(c) To generate electricity, a solar energy plant employs two processes. Photovoltaic cells convert heat energy into electric energy in one manner. Water is transformed to steam using heat energy in another manner. The turbines are then turned by steam, and power is generated. Solar power is the conversion of solar energy into electricity, either directly through photovoltaics (PV), indirectly through concentrated solar power, or a mix of the two. Solar tracking systems and lenses or mirrors are used in concentrated solar power systems to focus a vast region of sunlight into a tiny beam. The photovoltaic effect is used in solar cells to convert light into an electric current.

Note:Electromechanical generators, typically driven by heat engines fueled by chemical combustion or nuclear fission, but also by other sources such as the kinetic energy of flowing water and wind, are used to create electricity at power plants. Solar photovoltaics and geothermal power are two more technologies that can and are utilised to create electricity.
