How to Apply the Precautionary Principle to Wind Energy Projects

A Guide to Responsible Authorities, Departments of Planning and Health and Wind Energy Developers

The NHMRC’s Public Statement dated June 2010 included the words: “it is recommended that relevant authorities take a precautionary approach and continue to monitor research outcomes.” This statement does not offer the option of either – or. The statement was repeated by the NHMRC’s CEO in his oral testimony on 31st March 2011 to the Senate Hearing into the Social and Economic Effects of Rural Wind Farms where he said “that is why (referring to the lack of high quality scientific literature) we were at pains to point out that we believe a precautionary approach should be taken.”

The World Health Organisation states (in a 2004 document entitled: The precautionary principle: protecting public health, the environment and the future of our children):

“The Principle states that in the case of serious or irreversible threats to the health of humans or the ecosystem, acknowledged scientific uncertainty should not be used as a reason to postpone preventative measures.”

Despite the NHMRC’s recommendations about the need to apply the precautionary principle, regrettably there has been no detectable evidence that planning authorities, governments and developers have made an effort to actually apply the principle in a meaningful way. A principle is of value if it is simple to translate into action in the specific area for which it has been recommended; as long as it remains general, as in this case, it will be served with words rather than action.

Any thoughtful and proper application of the precautionary principle to the wind industry is likely to require rethinking of current layouts and some delay in the development of approved and to be approved projects. One could understand the industry being reluctant to see this happen, but neither the authorities nor the industry should be so reluctant if it involves possible detrimental and severe health problems for neighbours of yet to be built projects. Building wind projects designed on present incompetent noise guidelines certainly generates such problems.

The Waubra Foundation has long concluded that such a general principle would fail through lack of specificity. By defining the elements of the appropriate caution in respect to wind energy projects, developers and the relevant authorities can be helped to focus on what they should be doing to adhere to the intent and purpose of the recommendation to apply the precautionary principle.

After consulting with independent acousticians, a review of the most recent studies and its own field surveys, the Foundation has decided to publically state that the following elements need to be addressed in the specific application of the principle:

An additional general caution has to be that where turbine locations and neighbours’ health are in conflict, this is not a matter for compromise.

Citizens’ health cannot be expendable or negotiable!

Notes:
[1] dB(Lin) or dB(L) is sometimes referred to as dB(Z).
[2] dB(A) is basically a measure of audible sound.
[3] dB(G) is basically a measure of infrasound and some low-frequency sound.
