Obama on energy and climate

by

I find it sad that there was no explicit discussion of the incontrovertible scientific fact that we are destabilizing our climate with our energy system. Elsewhere in the world, this can be discussed frankly, but in the US, out of deference to half the political spectrum being in total denial, the elephant in the room cannot be named. There are aggressive goals for converting the energy system to “clean energy” with no discussion at all as to why that might be necessary.

Clean energy dreams

by

Many people believe the State of the Union is just political theater. While it’s true the speech last night was thin on specifics, one thing that was very specific was that Obama says he wants to cut subsidies to oil companies and give the money to clean energy instead. But everybody knows Big Oil controls Washington. Does this proposal have any chance at all? And what about the future of clean energy in a down economy with a glaring national debt?

Energy: Hydrocarbons in North America

by

The sheer scale of our dependency on nonrenewable, energy-dense "fossilized sunshine" is often lost on those who believe that renewable energy sources can supplant hydrocarbons at anything like today’s level of energy consuption. Thus it is prudent to examine the prognosis for fossil fuels within North America, as they will make up the bulk of our energy consuption for many decades to come…

Energy security

by

So what should we do? We must be explicit about why we want good domestic climate and energy policy. Let’s say that it is needed to achieve peace and stability. Let’s say that climate change and competition for dwindling energy reserves are both causes of instability and violence. We should make it clear that there the other causes of instability and violence – like nuclear proliferation and inequality – need to be dealt with too. Finally let’s be very clear that our vision for renewables and good domestic climate policy is totally inconsistent with the dominant approach to security.

Urban permaculture – 10 ebooks about sustainable city strategies, community and guerrilla gardening

by

In urban situations, space is limited, there may be little or no access to land, and various regulatory restrictions when it comes to gardening or backyard animals. We want to share some of the concepts that people have used in urban settings which allow them to circumnavigate these obsticles. Below is a list of some solutions practiced by various groups in cities across the nation. It is a mix of approaches, ranging from gardening to co-parenting, going across of aspects of sustainability.

Book review: Paolo Bacigalupi’s “The Windup Girl”

by

It’s not the apocalypse. And it’s certainly not the Death Star or the planet Tatooine. But The Windup Girl is a compelling vision of our industrial world as it could be in a low-energy future. Paolo Bacigalupi’s techno-political thriller imagines how, in the time after peak oil and economic collapse, global trade could return via airships and GMOs.

Passionate ambivalence and conspicuous indifference: The case against (but also for) renewable energy

by

I am a little surprised, then, to find myself feeling passionately opposed to a new experimental wind project being proposed in Milwaukee and will at some point need to sit on my hands to stop some unadvised posts from flying from my computer out into the world of public mis-conception. Using federal funds, the city of Milwaukee is proposing a 20 to 100 megawatt system on the lakeshore, in a prominent, yet unobtrusive location.

Wood heating and public policy

by

Energy is actively debated on several fronts these days. The Gulf of Mexico oil spill, drilling in the arctic, and the Alberta tar sands spark debate about the environmental wisdom of continued oil exploitation. Climate change is caused mainly by the combustion of fossil fuels, something that goes on at a spectacular rate around the world. Peak oil – meaning the maximum possible global production rate of conventional oil – has entered the mainstream discussion after a decade of lurking in the shadows. But judged by policy discussions about our energy future, wood heating is virtually nonexistent.
