Solar energy
The sun represents a huge energy source. Solar energy is used in various fields of activity, from agriculture to research. There are more and more discutions on this matter in Romania. Many cities in the country use during summer hot water provided by solar panels.
Tihuta Wind Power Station
Technical data:
- installed power: 250 kW
- vane wheel emplacement hight: 42m
- vane span: 29,5 m
- elecric energy anual production: 791 MWh at wind speed of 8 m/s si 302
MWh at a medium wind speed of 5 m/s.
In Romania there are four wind power stations: at Tihuta (Bistrita)- 250
kW, at Baia (Tulcea ) – 550 kW, at Corbu (Constanta).
Fuel energy
Fuel cells are mostly used for the propulsion of the vehicles or for steamers; Fuel cells are used both as batteries in small devices and for portable generators of up to 1 kW. They are an efficient alternative of re-chargeable cells. In comparison with batteries, they offer a longer operating time and an unlimited number of recharging cycles.
Hydroenergy
Most of Romania’s renewable energey is produced in hydroenergetic area. Vidraru dam, was at the time of its inauguration (1965) the fifth in Europe and the ninth in the world. The dam is erected on the slopes of Pleasa and Vidraru mountains. The turbines and the electric generators produce 400 GWh/year during a medium hydrologic year.
Geothermal Energy
Geothermal energy represents the heat in the underground fluids and rocks.
It is non-pollutant, renewable and it can be used to various purposes:
for heating houses, in industry, electric power generation.
In Bihor there are many geothermal sources. Nowadays spring water is used
in spas. In Oradea 5,500 apartments use geothermal energy.
Biomass
In Romania biomass is considered to be one of the mos important energy sources. Among fuels are used: waste wood products generated by the agriculture and wood-processing industries, urban waste.
