3. Renewable energy
Renewable energy is generally defined as energy
that comes from resources which are naturally
replenished on a human timescale such as
sunlight, wind, rain, tides, waves and geothermal
heat.
Renewable energy replaces conventional fuels in
four distinct areas:
electricity generation, hot water/space heating,
motor fuels and rural (off-grid) energy services.
4. Wind energy
Wind energy is a form of renewable energy. At first
wind energy was converted into mechanical
energy. It has been used since the beginning of
humanity as a means of propulsion on the water for
various craft and later as energy windmills.
5. In Romania, wind farms are
found in:
Dobrogea - 3634.7
Moldova - 257.59
Banat - 254
Muntenia - 516 035
6. Cernavoda nuclear power plant
It came into operation on 2 December 1996 at Cernavoda and it works with
heavy water as moderator, using enriched uranium and produces a single
reactor.
Cernavoda Nuclear power plant is unique in Romania. It produces about 18% of
the country's electricity consumption.
NPP is a joint assembly and construction facilities to produce electricity using
nuclear
based. Obtaining nuclear fission reaction is based on (decomposition)
nuclear chain. Facility that provides the conditions for obtaining and
maintaining the chain reaction is nuclear reactor. In principle, the reactor
consists of a central portion called the active area, in which the fission
reaction and the heat of the reaction developed.
7. Lotru-Ciunget Hydroelectric Power Plant
Lotru-Ciunget is an underground hydroelectric power plant located
in Valcea county, situated on the river Lotru. It is situated at a depth
of 140 m below the river Latorita. It is designed to come into
operation in 4-5 minutes in crises situations of Power System, the need
for electricity is high, helping to regulate power and frequency. The
supply of otter lake in the town of the same name. The plant was first
commissioned in 1972 and has an installed capacity of 510 MW
(for comparison, the Cernavoda reactor has a power of about 600MW)
and is equipped with three hydro-aggregates of Pelton turbines one 170
MW each.
