stationary application telecom
Stationary application - Telecom
  • Electrochemical device – DC supplier;
  • It is a suitable solutions in extreme conditions;
  • It helps in a low carbon footprint;
  • It is a interesting solution more, not is the BEST solution. It is better when used combined with other energy sources (batteries, PV and wind)
technologies pros and cons

average prices u kw
Average Prices (U$/Kw)
  • Fuel cell – U$ 3,000/Kw
  • Solar Photovoltaic – U$ 400 – 1,000/Kw
  • Wind Energy – U$ 0,11 – 0,22 /Kwh *

* Last prices in Brazil

conclusions
Conclusions
  • Today the people are more consciences about the environments
  • In Brazil the using the renewable energy in telecommunications companies is small
  • This type the energy is expensive, it is necessary the incentive programs
