How do I use Wind Power from Home?

Wind energy is the energy produced by wind, one of the first renewable
energy used by man. From early in the history of mankind, the wind was
used as an energy source (motor for boats or windmills pumping water or
grinding).

Today we explore its use to produce electricity.



The use of Wind Turbines
to generate electricity on a large scale began in Denmark at the end of
the last century and has spread worldwide. Through various components,
wind turbine generators use their power to produce electricity.



The turbines are run when the wind reaches a speed of about 19-21 km /
h (ie, it takes a wind of at least moderate intensity, a breeze is not
enough). When the wind stops, the wind farms use batteries to continue
to deliver electricity. The wind turbine generators usually have a
standard size (15 to 30 meters in diameter, with a capacity between 100
and 400 kW).



California has some of the largest wind farms in the world and its
turbines can generate about 1120 MW of power (nuclear power plant can
generate about 1,100 MW). The advantages of wind energy are largely
environmental, because unlike coal-fired power plants or fossil fuels,
smokeless, making it an attractive alternative given the current cost
of non-renewable fuels. Besides the cost of electricity produced by
wind is competitive with other forms of energy production (nuclear or
hydro), though this provided they are installed in places that meet the
appropriate

geographical and topographical features. Another advantage that
producers argue, is that modern wind turbines

rapidly recover all the energy used in its manufacture, installation,
maintenance and decommissioning.



Under normal wind conditions, a turbine costing two to three months to
recover all the energy involved in their own making. Laos installed
wind turbines at sea may have a better performance against
ground-based, depending on local wind conditions:



The disadvantages of wind turbines are, for many users, aesthetic and
environmental. Aesthetic because the presence of wind farms interrupted
and disturbed by the vision of the landscape and environmental because
birds do not die on its routes to avoid the blades of wind turbines.
Given these disadvantages, the Danes delimit:



There are several applications of wind energy, but at industrial level.
Now, we present a wind turbine designed for all supplies electricity to
an ordinary house. This is the Helix Wind Turbine, and comes in two
models, one with a capacity of 2 kW and a 5 kW depending on the needs
that have to supply the home. The tower of the helix has a height of 4
meters and a half and the price varies between 6,500 and 8,500 dollars.
The greatest grace of this turbine is its vertical design, which unlike
conventional propellers (horizontal), allows the use of wind from
different directions.



Basically, wind energy is used in homes for the production of
electricity. The wind turbines for the home are called Small wind
turbines, as wind turbines consist of low power (1-50W) and
consequently reduced size of the rotor blades (order of meters) and
towers with heights of less than 30 meters (a growing number of
experiences DIY wind turbines manufactured in house by non-experts
axions). The law that allowed the spread of Small wind turbines
generators for individual users is the Legislative Decree No.387 of
29.12.2003. This law provides that any facility producing electricity
from renewable sources, with a capacity below 20 kW, has the
opportunity to connect to the network in order to exchange with the
manager of the same energy, so as to compensate for each year that
provided with therefore minimize the power consumed and not cancel if
the cost of the bill. This also avoids the use of energy storage
devices to complex maintenance such as batteries.



A Small Wind Turbines for Home,
be it horizontal or vertical axis, is always composed of a rotor with
one or more blades that converts the kinetic energy of wind movement of
the shaft, a generator, a battery pack or if a network connection
inverter AC / DC to transform the electricity produced and adapted to
the characteristics of the distribution network. Factors influencing
the design of a mini-eolic home generator are multiple dimensions
depending on available space, required energy, noise, environmental
impact, and are all properly tested to maximize performance and correct
operation. Insights on: Use wind power home wind power or wind power

It's probably hard to understand the capabilities of electric
generation equipment, but perhaps with a small example may be clearer.
That a turbine has a power of 2 kW in one hour means that can generate
at most that amount of energy (2 kWh). This energy would reach for
example to keep 20 bulbs of 100 W burn to an hour (of course we hope
none of you have these in your house!). According to the National
Energy Commission, the average consumption of electricity in Chile is
3080 [kWh] (2005), thus making a simple calculation, we would need this
turbine will operate at maximum capacity for 4 hours daily throughout
the year to supply all our needs, which seems so impossible right?.
