Distributed wind turbine installations in the United States nearly doubled in 2017 from the year prior.
Electrical energy provides great benefits to those who are connected to a grid. For the billions who are not connected to a grid, the solution is local or portable power generators. Virtually millions of small communities, remote and isolated, need small or medium generators. Fuel powered generators are high in cost per kWhr, fuel supply is risky and unreliable. The solution is generating electricity renewably, where it is needed.
here are many niches that could be served with an off-grid, portable, renewable power generator. This discussion will focus on those that do not have reliable power as a result of not being served by an electrical grid.
The energy of a wind gust is typically 8 times that of the steady wind flow. A modern wind turbine has constraints preventing it from capturing the increased energy in a wind gust. A modern wind turbine, on average, captures 25% of the available kinetic energy from wind flow.
The problems encountered in generating electricity from the wind and delivering the electricity to a user are numerous. This post will address the essential element of this industry, converting the kinetic energy in wind into electricity.
