That's the question I'm scratching my head over while reading about the ambitious goals of one Douglas Jones, a 20 year old studying at the University of New South Wales (UNSW) in Sydney, Australia who hopes to turn his family's 1500 acre dairy and cash crop farm into a zero net producer of CO2 while increasing the farm's revenue at the same time.
As he puts it, "I hope to turn our farm into a model for people to learn about sustainability, and set a trend in industry by showing that increased revenues are possible without harming the environment."
In a nutshell, the project is a model for other farms to get involved producing their own biofuel using algae with which to run their machinery, utilizing the algae biomass by-products as food supplements for livestock, and recycling the waste back as fertilizer, biofuel, and methane to power the farm's electricity.
He's currently studying within the only full Renewable Energy Engineering program in the world which happens to be at UNSW, and he's calling his project "Farming for the Future".
And while I must admit I'm no farmer myself, his project sounds interesting if a bit ambitious. It should be interesting to see what you all have to say
