What is energy? Energy is the capacity of d oing a work.
Types of energy *thermal energy *chemical energy *electrical energy *nuclear energy *electromagnetic energy *mechanical energy *magnetic energy
C hem ical energy The chem ical energy is stored in substances, it can be released or absorbed d uring chem ical processes.
Electrical energyThe electrical energy is associated with a electric current, it m akeselectrically powered m achines, in other word s, it m akes that m ost m achines work.
Nuclear energy The nuclear energy is contained in the nuclei of atom s, and it is released d uring nuclear reactions.It is used to create electricity by boiling water to create steam that turns turbines insid e the power plant.
Electromanetic energy Electrom agnetic energy is the energy which is transported by electrom agnetics waves (rad io,TV, etc), lum inous energy is a tipe of electrom agnetic energy generate by the sun or artificial lights.
Mechanical energy There are two kind s of m echanical energy:* kinetic energy is the energy that contains the objects when are in m ovem ent.* potential energy is the energy that objects contains when they are in hight position.
Sources of energy There are two kind s of sources of energy: renewable and non- renewable.
The renewable sources cam e from unlim ited natural resources. L ike the Sun, the wind , the water, etc.The non-renewable sources cam e from natural sources lim ited . L ike the petrolium , the coal, etc.
Enviromtental impact *reservoirs can cover a lot of productive land and even destroy villages. *the reservois can damage the landscape. *can affect the animals and plants. *if the dam breaks, there can be lots of damages. *Wind turbines are a hazard for birds. *noise pollution is created with win turbines.
Energy power stations A power station is a place to generate energy. Solar power stations Wind power stations Thermosolar power stations Nuclear power stations Hidraulic power stations Thermic power stations Heolic power stations
