what is energy?

Energy is the capacity of a body to do work, its unit is the joule J.

- Energy-Kinetic energy-Mechanical energy-Thermal energy-Electrical energy-Nuclear energy-Electromagnetic energy-Sound energy

WHAT FORMS EXIST

-Control switch: controls the power used.-Differential switch: disconnects the electrical installation at home in case of problems.-Small automatic switches: Each PIA controls a certain circuit in the home.

wHAT ELEMENTS MAKE UP A DOMESTIC CIRCUIT

HOW DOES IT TRANSFORM

-Energy can be transformed, transferred, stored or fired.-Energy is always conserved, it can neither be created nor destroyed.

HOW IS ELECTRIC CURRENT USED AND CONSUMED?

-Power is the amount of electrical energy consumed.-Each element consumes the energy carried by electrons.-The greater the potential difference, the greater the energy transport.

WHAT EFFECTS DOES ELECTRIC CURRENT PRODUCE?

Heating effect

They heat up when the current passes, it depends on the intensity of current that circulates through the

Chemical effect

Magnetic effect

a magnetic field causes an induced electric current* in mechanical energy it moves motors*in sound energy through speakers and headphones

Electrolysis is the chemical reaction that occurs when a direct electrical current is passed through a chemical compound.When passing through, the former are attracted to the negative and the latter to the positive.It is also used to coat objects for decorative or protective purposes.

WHAT ARE ENERGY SOURCES

-Natural resource from which it is possible to obtain energy that can be transformed into other forms of energy.-Where is the energy we use in power plants produced?-In almost all power plants, huge turbines linked to a generator convert kinetic energy into electrical energy through the phenomenon of electromagnetic

power plants from non-renewable sources

The source of energy is fossil fuels, such as coal, oil and natural gas. When burned, chemical energy is released in the form of heat. Advantages: Can be installed anywhere because the fuel is easy to transport. Disadvantages: Generates highly polluting emissions into the atmosphere Nuclear power plant The energy source is a nuclear fuel, which is fused into smaller elements. Advantages: A lot of energy is produced with a small amount Disadvantages: generates radioactive waste. Danger of accident

RENEWABLE ENERGY POWER PLANTS

Hydroelectric power plant: The source is the potential energy of water Advantages: Does not pollute Disadvantages: Disrupts the ecosystem

WIND POWER STATION

Energy is provided by the movement of the wind Advantages: Wind is inexhaustible and does not pollute. Disadvantages: It causes great alterations to the landscape.

SOLAR POWER PLANT

The energy source is solar radiation Advantages: It does not pollute Disadvantages: Depends on the weather, so it is very intermittent.

POTENCIAL ENERGY OF WATER

Advantages: Does not pollute Disadvantages: Disrupts the ecosystem

What is sustainable development and what are the objectives for sustainable development?

Sustainable development meets the current needs of human beings and society

Climate change

We recognise our contribution to global warming and the resulting climate change. Our use of fossil fuels, deforestation and over-application of fertilisers have raised greenhouse gas levels. We witness its impact in altered weather patterns, rising sea levels and ecological disruption. We understand the urgency of our collective action to mitigate these impacts.
