A solar panel on every roof? In U.S., still a distant dream

by

Daunted by high up-front costs, U.S. homeowners continue to shy away from residential solar power systems, even as utility-scale solar projects are taking off. But with do-it-yourself kits and other innovative installation approaches now on the market, residential solar is having modest growth.

Disorder in world cities: comparing Britain and France

by

Irresponsible acquiescence to budget deficits and mounting debt by numerous countries has translated into austere fiscal policies and drastic cuts in social services. These choices have generated public protests in Latin America, Israel, Spain and Greece. I recently analyzed thirty years of disorder in French and British cities, the only European countries experiencing recurrent urban outbreaks.

Virtue, fashion and climate change

The current system will consume what we have in resources and erode what we have in skill until there is a catastrophe close to home enough for power to know that it must react, or lose power. Distant catastrophes have no effect. Moreover the market, contrary to the doctrine, sends no signals. The primary engine is oil and oil prices are protected. The other significant marker is food price and European and American economies have protectionist (cheap) food policies. So supply and demand are most deeply hidden where they are most important. Important scarcities are concealed, while frivolous drivers of spending are made extra-ordinarily visible!

Grow a Grocery!

by

Back in the early 90s, Unicorn Grocery’s founders felt frustrated at their lack of shopping options, and aimed to create the kind of place where they wanted to shop themselves—where their needs were met and their ethics not sold out. And so Unicorn was born. In the 14 years that have followed, it has remained a place we love to shop in, and a realistic, affordable alternative to the supermarket.

Jevons’ coal question: Why the UK Coal Peak wasn’t as bad as expected

by

In his book The Coal Question from 1865 William Stanley Jevons examined for how long the United Kingdom could continue to fuel its economy based on cheap supplies of coal. At the time the UK consumed about 93 million tons of coal providing nearly all of its energy supply. His estimate was that within a maximum of a hundred years, or perhaps even within one or two generations, production would be in retreat due to an increase in the cost of mining which would, in Jevons’ words, “Injure the commercial and manufacturing supremacy of England.”

In this post I’ll look back at history to show that Jevons correctly foresaw the fate of the British coal industry. In Britain a peak in production occurred around 1913 caused by increasing coal mining costs, lack of technological innovation, rising competition from abroad, a number of political decisions disadvantaging coal as a fuel source, declining profits, and a slump in British economic growth coinciding with World War I.

Review of Index of U.S. Energy Security Risk (U.S. Chamber of Commerce, 2011)

by

The U.S. Chamber of Commerce recently released its Index of U.S. Energy Security Risk: Assessing America’s Vulnerabilities in a Global Energy Market, 2011 Edition (80 pgs). This is an update of last year’s inaugural edition and is published by the Chamber’s Institute for 21st Century Energy, headed by Karen Harbert.

Renewable energy zealots must understand ‘Net Energy’

by

Was I surprised that last issue’s column, Can Renewables Outshine Fossil Fuels?, elicited a strong reaction, with written responses of support and derision? Not at all. It’s an issue that continues to divide the environmental community, and one which keeps us from moving forward as quickly as possible to conserve resources and relocalize as an era of cheap, concentrated, easy-to-get energy comes to an end.
