IMAGINE3: Four Possible Futures
I'm imagining four possible futures, based on David Holmgren's Future Scenarios framework. The framework considers how fast or slow oil decline interacts with destructive or benign climate change.
Brown Tech: slow energy decline with destructive climate change
Strong national policies drive responses to energy peak and climatic change. Centralized investment by corporations and governments give priority to getting more energy out of lower grade non-renewable resources (eg. tar sands and coal). The cost of defending urban infrastructure threatened by storms and future sea level rise consumes more resources, while droughts and chaotic seasonal changes reduce food production from broadacre and small scale agriculture.
Green Tech: slow energy decline with benign climate change
The renewable energy sources of wind, biomass, solar, hydro, tidal, wave etc. are growing rapidly, resulting in a more diverse and distributed mix. The relatively benign climate is allowing a resurgence of rural and regional economies on the back of sustained and growing prices for all natural commodities including feedstocks for biofuels.
Earth Steward: rapid energy decline with benign climate change
The shock of energy decline to the world’s fragile financial systems has been overwhelming, and has resulted in severe economic depression and short, intense resource wars. Rebuilding and stabilisation is no longer based on dreams of sustainability or restoring the old system. Instead people now accept that each generation will have to face the challenges of further ongoing simplification and localisation of society.
Lifeboats: rapid energy decline with destructive climate change
Supplies of high quality fossil fuels have declined rapidly, and the economy has failed. Human contributions to global warming have collapsed but lag effects and positive feedbacks in the climate system continue to drive an acceleration of global warming. Low input forms of oasis agriculture have evolved that stabilize food production since chaotic seasons have made traditional field agriculture and horticulture almost impossible.

I'm reading David Holmgren's book "Future Scenarios" too. He wrote it in 2008. Very insightful.

Fourth of July on the Lake
This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More
Stinging Nettle
In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ**stances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More
The meal
It is 7'oclock, I was late home from work due to an assignment that i wanted to get ahead on. By the time I get home I am feeling extremley tired and I cannot be bothered to make a proper meal. I walk to the fridge and open it to see what there is for me to eat. All of the out of date foodstuffs have been automaticaly thrown away by the fridge, they will be recycled tomorrow as animal feed or something. I see i have organic local eggs and some local cheese. Foods are vacc** sealded for easy…See More
Future
FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More
public servants
The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
