Leftist greens fantasise of replacing all nuclear and fossil fuel power plants with big wind farms and big solar energy arrays. But there is a huge problem with that approach, which if pursued will lead to a drastic reduction in available electric power and a general impoverishment of any society that proceeds too far.
The most that big wind, for example, can safely contribute to a modern power grid, is between 6% and 20%, at the most.
The analysis reported in this study indicates that 20% would be the extreme upper limit for wind penetration?
Very high wind penetrations are not achievable in practice due to the increased need for power storage, the decrease in grid reliability, and the increased operating costs. Given these constraints, this study concludes that a more practical upper limit for wind penetration is 10%.? _Reason Foundation

?wind turbines by themselves do not add electrical capacity to a grid. They must be paired with other generators of equivalent power to compensate for wind variations and for the stability of the electricity grid.
This pairing?wind and backup?has limits because of the huge rapid variability of wind that must be compensated for by the backup power source. It is estimated that this pairing can account for only 20 percent of the capacity of the grid. This means that wind can be only 6 percent of the generation (.20 x .3). This limit has already been reached in Europe by countries such as Germany and Denmark. _Ulrich Decher PhD
In addition to Germany and Denmark, other countries under EU environmental laws and regulations ? including the UK ? are in danger of entering the blackout zone via a green dysfunction of faux environmental zeal.
Al Fin began his exploration of energy with a strong a priori belief in support of both big wind and big solar energy. In the course of teaching himself about energy, he assisted a number of installations of home-scale wind, solar, and micro-hydro systems. These projects were educational as well as fun. People who are willing to work to build off-grid small scale power can be fun to be around, and often know how to party.
But there is a huge difference between using wind (and solar) for off-grid residencies, and attempting to use large-scale wind as a large proportion of total energy generating capacity for a finely balanced continental power grid. That is the lesson that Al Fin had to learn, and which modern societies must now learn ? before they destroy themselves in pursuit of impossibilities.
Good intentions can make one feel good about himself, but hard-headed, knowledge-based policy is what will keep a society prosperous and healthy. Green policies ? such as the lefty-Luddite green dieoff.orgiast policies promoted by the US Obama administration, the Julia Gillard government in Australia, or any one of a number of European governments (and the EU in general) ? will eventually destroy a society through energy starvation and impoverishment. Such societies eventually pollute the air, water, and soil in far more damaging ways than societies which were allowed by prosperity to move up the energy technology curve ? eventually arriving at safe, clean, and abundant sources of reliable and predictable power supplies.
Ideological efforts to short-circuit that trajectory of development ? such as modern green leftist ideologies ? will doom any societies which adopt them to ultimate failure.
Wind energy is unpredictably intermittent ? and thus unreliable. It is also enormously expensive in terms of materials, land, money, and other scarce resources.
Big wind will take any problem you are trying to solve ? and make it worse.
The renewable energy industry cannot survive without massive government handouts and stimulus. As economic slowdowns settle over Europe, the US, China, etc., governments can not afford to be as generous to big wind and big solar as in the heady days of economic booms and bubbles. Consequently, the renewables industry is beginning to suffer.
It is fine to hold strong opinions. But make sure that they are backed up with something stronger than good intentions. Parts of this article were adapted from an earlier Al Fin Energy piece.
