Consumption & Demand

Commentary: Peak Oil: Yes, still a serious issue

by

The director of the U.S. Geological Survey (USGS) will be delivering a lecture titled “U.S. Energy Outlook: Whatever Happened to ‘Peak Oil'” at Indiana University on February 6. The description of the lecture provides some background: “Not long ago, the public heard much concern that the nation and the globe had reached or was about to reach the point of peak oil production and would be on a downward trajectory due to declining resources. Despite growing demand for energy, however, fossil fuel resources have never been higher.”

Oil prices, exhaustible resources, and economic growth: report extract

by

This chapter explores details behind the phenomenal increase in global crude oil production over the last century and a half and the implications if that trend should be reversed. I document that a key feature of the growth in production has been exploitation of new geographic areas rather than application of better technology to existing sources, and suggest that the end of that era could come soon. The economic dislocations that historically followed temporary oil supply disruptions are reviewed, and the possible implications of that experience for what the transition era could look like are explored.

Changing the social logic through design

by

In Prosperity Without Growth, the seminal book by Tim Jackson, he concludes that our social logic must change: “The social logic that locks people into materialistic consumerism as the basis for participating in the life of society is extremely powerful, but detrimental ecologically and psychologically. An essential pre-requisite for a lasting prosperity is to free people from this damaging dynamic and provide opportunities for sustainable and fulfilling lives.”

After the nuclear disaster, Japan considers a green future

by

Last March, a 9.0 magnitude earthquake and subsequent tsunami left nearly 20,000 dead or missing and destroyed 125,000 buildings in the Tohoku region of Japan. The two disasters also caused three reactors at the Fukushima Daiichi nuclear power plant to melt down, which released dangerous levels of radiation into surrounding areas and led to national power shortages. Tokyo’s iconic neon signs were switched off as rolling blackouts spread across the country. Faced with the greatest reconstruction task since World War II, Japan is asking difficult questions about the future of its energy supply and just what sort of society should emerge from the ruins.

Indian villagers’ lives transformed by new energy delivery system

by

It’s late December and an icy fog cloaks the northeastern state of Uttar Pradesh. Here, far from the cities, smoke rises in dense, choking spirals from meagre wood fires and scantily-clad children shiver against the cold. These are largely farming families, and their mud huts fortified by the occasional brick wall are for the most part devoid of light, heat or clean water. But it is here in Uttar Pradesh, one of India’s largest and poorest states, far away from the country’s straining power grid, that US-born entrepreneurs Nikhil Jaisinghani and Brian Shaad have started to pioneer a wholly different energy system, designed to meet some of the most basic needs of the poorest.

Basking in the sun

by

Who hasn’t enjoyed heat from the sun? Doing so represents a direct energetic transfer—via radiation—from the sun’s hot surface to your skin…We have already seen that solar PV qualifies as a super-abundant resource, requiring panels covering only about 0.5% of land to meet our entire energy demand (still huge, granted). So direct thermal energy from the sun, gathered more efficiently than what PV can do, is automatically in the abundant club. Let’s evaluate some of the practical issues surrounding solar thermal: either for home heating or for the production of electricity.
