Guys, this isn't Longboarding, but I wanted to throw it out there...
The Romans had their 5-10-15 year intervals between major conflicts / wars / take overs... From 1900-2014, we aren't much different, as a world, but on a larger scale... We still have wars on similar intervals...
Romans had water & sewer as their major infrastructure developments. Plus some good engineering and concrete...
We have ENERGY, instead of water... Gas, Petrol, and Electricity, that underpins our civilisations...
I have "greenie" "mates"... But being green is pretty much a phallicy (phellic/wank!) in our current civilization... We all consume ridiculous volumes of energy... But some strive to be 10% to 20% more energy efficient... The full-on 60's 'commune' is the real winner... But my cousin wasn't able to stick it out either (in the commune)... Real commune living, is "off grid power" / no power!..., maybe 1 car between 20 people, so you can get "essentials" (I use this term broadly...) ...items from town, or go to the doctors, for the kids, etc... Fully self sufficient, or at least 99.5% self sufficient is the future...
The future of energy: .... Energy underpins our current civilisation... You think it might be underpinned by commerce or finances... But it's the energy sector that defines the way we want to live... Electricity & Gas to run our homes, and petrol to run our cars... Without that energy, our society as we know it would be screwed!
The good (and bad) news... We have stacks of energy left... Hundreds of years... We are inventing technology to get energy from "deeper" off shore wells...(gas for power and cooking, and petrol for cars, etc)... (also see BP's Deep Sea Horizon Project - that was the stuff up, but we as humans have learnt heaps from this disaster)...
Grid Power / Electricity - I'm really sorry, but Solar and Wind can't get above 20-30% of grid supply, without significant battery back-up improvements/inventions... They are unreliable sources of daily energy requirements... Yes, we live day-to-day in terms of electricity production... It is carefully balanced and monitored by the High Voltage Electricity Supply "Guys"... (perhaps in the future, we will have masses of excess Solar and Wind, and some battery back-up, to balance the system, when solar is "low/off", and when wind is "slack")... The medium term solution is perhaps 30% coal, 30% gas (including renewable gas methane / dirty "poo" methane / methane from sewer systems...), plus 50% solar, and 50% wind = 160%! Yes, 160%, to cover when wind and solar aren't performing... Yes, an inefficient system, but "friendlier" system!... Maybe... But harder to manager...
I really think that sustainable future is 1 Billion people, world wide, and a 1 child policy (for the entire world - hats off to China!)... Europe's re-grouping into the EU needs to be heavily commended... It's like the old Roman Empire! it should provide a better balance across societies/communities, even though it comes at higher cost... Just like the Roman Empire...
The "futurist" within me believes that in 500-1000 years, we will be back at 1 Billion People, in a "dark ages" style existence...
The alternate - we eradicate war, and social/racial boundaries, but still "cap" the population, ... and if we can solve the impending energy crisis... then our current version of civilisation can continue for a longer term...
The future energy crisis... this is why I think that Ecologically Sustainable Battery Technology will be the saviour of our society... Eco Friendly Back-Up Power, and Battery Power to cars/transport, will form a big part of out future, if we want to continue consuming these volumes of energy...
