Co-operative renewable energy in the UK: a guide to this growing sector (report)

by

Co-operatively-owned energy generation is a vibrant and growing sector in the UK. The first co‑operatively-owned wind turbines, Baywind in Cumbria, started turning in 1997. Since then, over 7,000 individual investors have ploughed over £16 million into community-owned renewable energy. This report summarises insights gained from visits to five co-operatively owned energy projects during the summer of 2011.

 

The peak oil crisis: closing out the year

by

The year ended with little change in the assessment for the prospects for global oil supplies. Despite all the hype concerning new oil finds and technological breakthroughs in oil production, these developments still are not contributing enough new oil to offset the annual decline of 3 million b/d from existing fields and the annual increase of circa 1 million b/d of new demand. The bottom line among those following this issue is that global oil production likely will start to decline in the next one to five years as depletion gets ahead of very-costly-to-produce new sources of “oil.”

Waiting for the Great Pumpkin

by

At the beginning of every year, the peak oil blogosphere sees a flurry of predictions for the coming year. A surprisingly large number of these predictions are the same ones that were offered in previous years, and didn’t happen. Is this simply a matter of impaired collective memory, or is something deeper involved? The Archdruid considers the question.

The weird season

by

On January 1, it was 48 degrees on my farm. My sons were at the playground, dressed in sweatshirts and jeans, rather than winter coats and mittens. Their ice skates had yet to be used this year. Their sleds haven’t even come out of the garage. Walking out in the warm weather among the goats, I noticed my cowslips and primroses are up and there are buds on the pussy willows…

Now weather is complicated and climate is complicated and you will note that I make no claims about what has or hasn’t influenced things…The aggregate of my research and watching my site probably isn’t worth very much scientifically – I haven’t lived here long enough and the local data wasn’t taken from my precise site, so its value is uncertain. What it does teach me is that adaptation to complicated weather is something that has to be a priority in our lives, however.

Maybe old tractors do die

by

Ethanol in gasoline is not the wonder fuel it has been made out to be. It is causing problems when used in off-road vehicles— lawn motors, chain saws, boat motors, four wheelers, not to mention old tractors. Although I have had no cause to complain yet myself, I first heard rumors of these problems when 10 percent ethanol was added to gasoline (E-10 fuel. Now that the EPA has approved 15 percent ethanol in gasoline (E-15 fuel) the complaints are increasing.

Nuclear options

by

A recent thrust on Do the Math has been to sort our renewable energy options into “abundant,” “potent,” and “niche” boxes. This is a reflection of my own mathy introduction to the energy scene, the result of which convinced me that we face giant—and ultimately insurmountable—hurdles in our quest to continue a growth trajectory. It is not obvious that we will even manage to maintain today’s energy standards…Meanwhile, requests for me to address the nuclear story are mounting. So before readers become mutinous, I should interrupt the renewable thread to present my nuclear reaction.
