• Active utilization with the help of collectors
• air collector
• liquid collector
• flat collector
• vacuumed pipe collector
• Active utilization with the help of solar cell
• amorphous
• onecrystal
• policrystal

15
Utilization of solarenergy

• Fields
• population,
• agriculture,
• industry,
• servicing.
• Its made of action
• producing warm water for usage,
• heating of buildings,
• heating the water of pools,
• drying, dehydration, airing
• production of electric power

16
Tasks in the interest of increasing the
utilization of energy

• In university level knowledge centres,
  the widespread of the possibilities and
  accomplishment of solar energy utilization and
  making regional plans.
• Environmental viewed forming of consciousness in
  the media and in instutitions.
• Determining and making up of innovation,
  search-development tasks.
• Elaboration of simplified, subject-based
  supportment methods, with combination of bank
  constructions, and with the participation of the
  state.
• Assuring of egual opportunity, eg
  electrification of ranches with renewing based
  electric power production
• In case of suppor, equal support of active
  and passive utilization methods Surveying of
  state and municipality owned buildings in the
  interest of utilization of solar energy and the
  developing of its sample systems

17
Wind power
18
Disadvantages of wind power

• Unsuitable for continous use
• Bald environment
• Noisy
• Bird danger
• Small power

19
Advantages of wind power

• Not pollutant
• To reticulate
• Long life
• Good rate of return
• Take advantage of the area

20
Water energy
21
Water energy source

• river
• sea current
• ebb and flow

22
Advantages of water energy

• energy storeable
• It can make electric energy any time
• revive
• permanent readiness
• hydroelectric power station can do other tasks

23
Other utilizations of hydroelectric power station

• irrigation plant
• Reduce the danger of floods
• water sport, recreation

24
Environment influence effect of hydroelectric
power station
