1. WHY WIND POWER?
•Ensuring environmental sustainability: Wind energy does not pollute, is inexhaustible and slows the depletion of fossil fuels and the greenhouse effect. It is a technology leader in preventing CO2 emissions
•It is a domestic energy. Consume resources that are all around us decreases distribution costs, increase energy efficiency and decrease dependence on external supplies.
•Creating wealth and employment: The wind industry employs over 35,000 people in Spain, with positions permanent and quality. Renewable energy creates five times more jobs than conventional energy compared to its turnover.
•Source of cheap energy: •Wind power technology is the most competitive of the special. Low electricity prices by displacing more expensive combustion technologies in the market. In 2009, reduced the cost of electricity by 3.4 € / MWh.
vs
Traditional system of large central electricity
Microgeneration
wind turbine (1.5KW) can reduce electricity bills between 50 and 90%.
Reducing transport losses To achieving greater energy efficiency
Ideal for powering places with difficult access to the network or with complex orography.

visual impact
Noise impact
Impacts to wildlife
Transport losses
Difficulty of expanding the grid for territory
Promotes sustainable development cities.
2. MICROGENERATION VS MACROGENERATION
Works with moderate wind speeds, requires no complex feasibility studies.
Easy integration into building
3. WHY WE ARE FREEWIND THE WIND POWER??
Free technology promotes R & D. The community provides input to find the most efficient design at the lowest cos
Technology accessible to all. We believe in a sustainable socio-economic model, where the consumer is your own energy producer. Open hardware designs available publicly promotes its implementation and development to be fast and efficient. Anyone can study, modify, build and distribute.

Costs
The supply of electricity to homes and industries based on the exploitation of wind energy technology is an option increasingly used
So far these projects have raised individually. But it is observed that the combination of micro-generators in networks is a more optimal solution.
This alternative design incorporates the option of using computers to generate more power, proportionately cheaper, and consumption condition prevents a family wind resources available at home.
4. FREEWIND PROYECT: Real case
Real case: El Alumbre
• COSTS WERE REDUCED by 20%, reducing the number of wind turbines in 10 units.
• The model of micro-networks, allowed to meet increasing demand with a lower cost increase:: 58% in micro-networks designs compared to 72% in individual designs
