How to Use Wind Turbines to Offset Your Business Electricity Bill

Global NRG micro wind turbines are able to generate renewable energy from wind at low wind velocities in singular and multiple applications. They can be used on a variety of sites including home roofs and gardens; high rise and factory building rooftops; municipal and government buildings; schools; universities; sporting fields; railway stations and tracks; parks; clubs, shopping centres; along roads. They are also used in conjunction with the patented NRG Economizer power storage system, which allows homes and small businesses to reduce their electricity bills from 35% to 100%. The NRG Economizer system also has multiple applications in high rise buildings, factories, schools and public buildings, where a significant amount of renewable energy can be generated and stored for later use. They are also used in hybrid solar/wind street lighting.

Solar PVs are a very expensive and inefficient way of generating renewable energy, for they only work effectively for around 4 hours a day if the sun is shining; this usually occurs, outside peak demand for electricity, which occurs in the early morning at around 7.00 am to 10.00 am and between 4.30 and 10 pm later.  Wind turbines however are able to generate renewable energy 24/7 when wind is available, taking up only a fraction of the space required to site solar panels.  A geared wind turbine of up to 50KW can generate at a 40% load factor at wind speeds of just 4.2 m/s (15.2 km/hr).


NRG wind turbines have been designed to address past constraints such as size, noise, vibration and output, bringing new technology and solutions across multiple markets, for homes, businesses, mines, farms and rural and remote areas, to capture kinetic energy from wind.


The renewable energy is then fed through electricity inverters to supply building power, or through grid controllers and inverters into the grid and energy storage units.

How wind turbines work

Wind power involves converting kinetic wind energy into renewable electricity using wind turbines. A wind turbine comprises of 3 or 5 propellers-like blades mounted vertically or horizontally which make up the rotor. The rotor is attached to a tall tower or pole which can be mounted in the ground; fixed to a wall mounting, or a rooftop. On average wind turbines need to be located about 20m high, where  the winds are clearer and stronger.

Wind comes is caused by atmospheric changes; changes to temperatures and pressures which make the air move around the surface of the earth; all of which is brought about by the sun. Wind energy can be regarded as a form of free energy.

Conversion of wind into electricity via a wind turbine

Wind power driving the turbine is converted into electricity through magnets moving past stationary coils of wire known as a stator. As the magnets pass the stator AC electricity is produced. It is then converted into DC electricity using inverters.

The benefits of wind power

Wind power is a clean energy that can be relied on to supply low cost renewable energy for the present and the future, creating energy without using fossil fuels, producing greenhouse gases, or radioactive or toxic waste. Wind power helps reduces GHG emissions.

Small wind turbines can be installed in areas which normally are inaccessible to large scale wind turbines. They are low noise and do not cast the rotating shadow of large turbines that affects people’s and animal’s heath.

A single wind turbine can be sufficient to generate enough energy to power a household. A bank or matrix of wind turbines can cumulatively be aggregated to provide an impressive amount of power. By joining one matrix with other matrixes of wind turbines through a control centre it is possible substantial amounts of power which can equal the output of a 60 MW coal fired power station, yet cost only a fraction of its cost to build. These matrixes can be built and installed in a quarter of the construction time it takes to build a similar coal or gas fired power station.

Backed up with biowaste gasification power plants, the power fluctuations caused by wind variance on power generation can be smoothed out, with excess syngas being stored and sold into the domestic and industrial markets when not required to back the wind turbine matrixes
