Unsustainable cow manure
Sustainable, affordable, eco-friendly renewable energy, my eye
Paul Driessen, 21 September 2010

Excerpt,
" It may be useful to address some basic issues, before going further down the road to Renewable Utopia.

First, when exactly is something not sustainable? When known deposits (proven reserves) may be
depleted in ten years? 50? 100? What if looming depletion results from government policies that forbid
access to lands that might contain new deposits – as with US onshore and offshore prospects for oil, gas,
coal, uranium, rare earth minerals and other vital resources?

Rising prices, new theories about mineral formation, and improved discovery and extraction technologies
and techniques typically expand energy and mineral reserves – postponing depletion by years or decades,
as in the case of oil and natural gas. But legislation, regulation, taxation and litigation prevent these
processes from working properly, hasten depletion, and
make “sustainability” an even more politicized, manipulated and meaningless concept. "
