This page aims to show that mankind's four fundamental resources are in fact hugely abundant:
 In the past a lack of technology could be considered a significant cause of scarcity but that is certainly not a reason any more. Despite common perceptions, there is no actual lack of material or energy available to us. Emerging methods of co-operation and advanced automation have the potential to unlock these resources to provide a good standard of living in all parts of the world, while causing minimal harm to the natural environment - a combination that although is hard to imagine today and might appear at first glance to be contradictory, is very much possible. An important trend in technological progress is the tendency of products and processes to steadily become more effective while using less material and energy – i.e. doing more with less – something that Buckminster Fuller
Extracting these plentiful elements (and their compounds) to create useful material essentially involves energy (which is also plentiful) and the right processing methods. From a technical point of view there is practically no limit to the volume of material we could extract and make use of, if we so wished, even while minimally disrupting complex and fragile ecosystems. The reserves of raw materials needed to sustain civilisation are simply not going to run out, because the entire Earth's crust The point is that any existing material scarcity actually has little to do with the reserves at our disposal.
 Humanity consumes 15 terawatts of energy[1] and this is projected to rise to about 30 terawatts. This is a tiny amount of energy compared to what is available around us: 72 terawatts of available wind energy at ground level[2], 150 terawatts in the jet streams[3], 44.2 terawatts of geothermal energy [4], 2 terawatts of easily-exploitable wave power[5] and 174,000 terawatts of solar energy[6]. We clearly have tens of thousands of times the energy we need, the key is our ability to harness this energy. This article explores existing and emerging technologies for doing this. Steadily increasing energy efficiency The issue currently is monetary economics. The bottom line is that with the current economic framework it is still 'cheaper' to pump oil out of the ground and burn it to produce power than use other more plentiful, renewable and environmentally benign sources. These alternative energy sources are sitting right in front of us waiting to be harnessed. It may be that open-source methods can bypass the incumbent economic system to enable plentiful, environmentally-friendly power.  One significant aspect is that information can now completely describe the physical structure of man-made items, and can be communicated to automated fabrication machines which can then manufacture the product, reducing the requirement to transport material goods great distances to the end user, as happens generally now. Most of the journey will effectively be spent as information travelling at the speed of light. (See section on turning virtual designs into physical objects).
