Historically, humans have encountered similar natural resource shortage problems before, and were able to proactively circumvent them. In the early stages of human expansion over the world, migration into less inhabited, less depleted regions of the earth permitted roving groups of people to avoid the negative effects of local natural resource scarcity. Substitution of natural resources became a more common strategy for overcoming scarcity than migration as permanent human settlements gradually saturated the earth’s surface. Domesticated animals and plants substituted for wild game and plants, coal substituted for wood, kerosene derived from petroleum substituted for whale oil – and now we have to find substitutes for petroleum.
At this time, only three energy sources can technologically provide energy day-in and day-out at a scale that will support the ‘standing crop’ of humanity: Continental hydropower, fossil fuels, and nuclear energy. The most important limiting factor preventing near term utilization of wind and solar energy is the technical inability to store sufficient amounts of these episodic, renewing energy sources for use when the wind isn’t blowing and when the sun isn’t shining. Significant expansion of continental hydropower is not possible as nearly all water energy sources have been put into harness, which leaves only – for the time being – the established technologies of utilization of fossil and nuclear energy as substitutes for the ever-declining availability of the readily utilized fossil fuel of petroleum.
Gwenyth Gravens’ Power to Save the World – the Truth about Nuclear Energy [2] (2007, Knopf, New York) contrasts the positives and negatives of using coal or uranium to fill the emerging energy gap. Specific excerpts from her text that answer the questions of why nuclear energy is preferable to coal energy (much less surface impact, much less process waste), and that address the cultural doubts about the safety of nuclear energy can be read at:

The above explains the basis for DIR Exploration’s involvement in exploration for uranium collapse breccia pipes in northern Arizona:
There is a near- and long-term need for energy substitutes for the dwindling supplies of petroleum.
Nuclear energy is a preferable energy substitute over coal because of its far smaller disturbance of the earth’s surface and subsurface, and because of its far smaller output of waste products.
Nuclear energy is currently more practicable than wind and solar power because it provides energy output day and night, and throughout the seasons.
Uranium production from northern Arizona collapse breccia pipes requires minimal energy inputs, results in minimal disturbance to the surface and subsurface, and creates no contamination or other disturbance to the regional aquifers and surface water drainages.
