Blow-by-Blow PV System Efficiency: A Case Study for Storage

A short while back, I described my standalone (off-grid) urban photovoltaic (PV) energy system. At the time, I promised a follow-up piece evaluating the realized efficiency of the system. What was I thinking? The resulting analysis is a lot of work! But it was good for me, and hopefully it will be useful to some of you lot as well.

The close tie between energy consumption, employment, and recession

The number of jobs available to job-seekers has been a problem for quite a long tine now—since 2000 in the United States, and longer than that in Europe. If we look at the percentage of the US population who are employed, it is now back to 1984 or 1985 levels. I have run into a number of clues about what is happening. In this post, I’d like to discuss what I am seeing.

A write-up of the 2012 Transition Network conference. The best yet.

Transition folks from around the world gathered last weekend at Battersea Arts Centre for the 6th annual Transition Network conference. In a week when the Arctic ice reached its smallest ever extent, scientists warned that the world’s weather could be on the verge of running amok and it was suggested that Saudi Arabia, always meant to be the ‘swing producer’ on whom the rest of the world could depend for reliable oil supplies, may become a net importer of oil by 2030, the theme of the conference was, appropriately, ‘Building resilience in extraordinary times’.

Hopeful Harvest: Food and agriculture as a foundation for peace in Northern Afghanistan

This apparent disconnect between the symptoms of a failed state and the remedies suggested by what is seen to constitute its healthy counterpart makes it difficult to imagine a way out of failed-statehood. We contend that it is necessary to rethink what a failed state is, to understand, at a rather more practical, grassroots level, the drivers of failed or successful societies.

Hierarchy and money in a global hall of mirrors

Many authors have written about alternative forms of money, so I don’t need to canvas the topic. But I’m still thinking about the digitization of money and its role in our current monetary predicaments. I recently watched a movie about time as an alternative currency, and I also attended a local lecture on time-banking. These thoughts converge for this post about traditional and alternative forms of money as an illustration of the hierarchy of money. Our economic information systems evolve with increasing complexity to match the complexity of our economies.

Report from a meeting in China about the pipelines for oil export from Canada’s oil sands

One of the reasons that I am in China just now is that Uppsala University is discussing increased collaboration with the Chinese University of Petroleum in Beijing, CUPB. It is Professor Feng of the School of Business Administration at CUPB that leads research on Peak Oil at that university. He has just organised a workshop with the theme “The Impacts of Peak Oil”.

What does it mean?

In the word-cloud of current events, the phrase “parasitic financial system” billows up to a degree that suggests even so-called thinking persons begin to understand what’s happening: that banking shenanigans are sucking the life out of advanced societies. That’s why Matt Taibbi’s metaphor of Goldman Sachs as “a Vampire Squid jamming its blood funnel into anything that smells like money” remains so potent years after it was minted.

The green tea ecosystem of Shizuoka

Throughout Japan there exist landscapes called satoyama in which people live and work in harmony with nature by combining traditional wisdom with scientific knowledge to practice agriculture in a manner that nurtures biodiversity. This article complements the video brief that looks at green tea produced in the village of Higashiyama, Kakegawa City, Shizuoka by using grassland resources to protect and augment soil, yielding a high quality product and giving haven to other plants, some of them important to Japanese culture.

Occupy your victories

Occupy is now a year old. A year is an almost ridiculous measure of time for much of what matters: at one year old, Georgia O’Keeffe was not a great painter, and Bessie Smith wasn’t much of a singer. One year into the Civil Rights Movement, the Montgomery Bus Boycott was still in progress, catalyzed by the unknown secretary of the local NAACP chapter and a preacher from Atlanta — by, that is, Rosa Parks and Martin Luther King, Jr. Occupy, our bouncing baby, was born with such struggle and joy a year ago, and here we are, 12 long months later.
