What is Distributed Energy?
Monday, May 11th, 2009
BBC Politics and Energy — Economist Jeremy Rifkin galvanised the Research Connections 2009 conference in Prague with a roadmap to simultaneously solve the economic and energy crises. He proposed a pan-European strategy of small-scale energy generation and smart energy grids that make everyone a partner in energy. What is more, he said, the plan would create millions of jobs and foster investment that would see the end of the current economic crisis.
Mr Rifkin leads a roundtable of 100 top CEOs and government officials who have subscribed to the plan. The roundtable is part of the Foundation on Economic Trends, which Mr Rifkin founded.
He said old economic models will not see humanity through, and the combination of the climatic, energy and economic woes of the planet created a “perfect storm” that will see in a new era for its inhabitants. But such a revolution is not unique to human history, he said.
“The great economic revolutions in history occur when two things happen. First, we humans change the way we organise the energy of the Earth; we’ve done this frequently over the course of our history. Second, and equally important, we change the way we communicate to organise new energy regimes. When energy revolutions converge with communication revolutions, those are the pivotal points in human history.” …
Although the sheer scope of the idea raised eyebrows throughout the room, Mr Rifkin laid out a cogent, four-part plan that he said could in one stroke dispel the perfect storm he described.
The first two pillars of the plan were a call to technological arms: further develop renewable energy technologies’ efficiencies, amplify production to access “economies of scale”, and develop means to store the intermittent energy they harvest.
The third pillar is a common idea writ very large indeed. He called for a pan-European commitment to microgeneration - small installations of renewable energy technology work in place of, for example, vast wind farms - but on every single building already up or yet to be built.
“We cannot build enough centralised wind and solar parks to run Europe,” he said. “If this energy is distributed over every square foot all over the world, why would we collect it only at a few points? The problem is we’re using 20th century, centralised, top-down business models.”
Instead, Mr Rifkin suggested overhauling the technology of infrastructure and architecture such that buildings have integral power generation: solar panels and small vertical wind turbines on roofs, heat pumps harvesting geothermal energy in basements. In rural settings, agricultural waste could be used to generate methane and in coastal regions, tidal power could be harvested.
“Your building becomes your power plant, just like your computer becomes your information vehicle to the world. Every home, factory, industrial park, every building is converted,” he explained. While existing buildings could generate a sizeable fraction of their energy demands, new buildings would be “positive power” - generating more than they need through grand changes in building materials and architecture.

Imagine a group of 100 fisherman faced with declining stocks and worried about the sustainability of their resource and their livelihoods. One of them works out that the total sustainable catch is about 20% of what everyone is catching now (with some uncertainty of course) but that if current trends of increasing catches (about 2% a year) continue the resource would be depleted in short order.
