South-South technology transfer in Bolivia: A solution for local health, forests, and our global climate

by

These cooking devices rely only on power from the sun and are built entirely with materials indigenous to Bolivia. It is the kind of solution that embodies many of the elements necessary to really get to work solving climate change—local, small-scale, incorporating indigenous knowledge and materials, and with simple, easy-to-use technology.

Bring me the woodburning stove of Alfredo Garcia….

by

If everyone installs woodburning stoves, might we end up back in the age of smogs? Are we better to explore group solutions, anaerobic digestion for example, which might still be able to supply us with gas (albeit to far more efficient homes than at present) or other large scale renewables, rather than all fracturing down into small off-the-grid bubbles?

Real-world tests of small wind turbines in Netherlands and the UK

by

Two real-world tests performed in the Netherlands and in the UK confirm our earlier analysis that small wind turbines are a fundamentally flawed technology. Their financial payback time is much longer than their life expectancy, and in urban areas, some poorly placed wind turbines will not even deliver as much energy as needed to operate them (let alone energy needed to produce them).

A report from the launch of the Totnes Renewable Energy Society

by

Last Friday, in Totnes Civic Hall, saw the historic launch of the Totnes Renewable Energy Society (TRESOC). A key piece in the relocalisation of Totnes and district, TRESOC offers members of the community the chance to buy into their own renewable energy company.

Steady growth of wind industry moves EU closer to green goals

by

Europe is in the midst of a wind energy boom, with the continent now installing more wind power capacity than any other form of energy. In an interview with Yale Environment 360, the European Wind Energy Association’s Christian Kjaer describes his vision of how wind can lead the way in making Europe’s electricity generation 100 percent renewable by 2050.

A symbolic solar road trip to reignite a climate movement

by

As I write this piece, we’re in the midst of a (biodiesel) road trip to Washington, D.C., towing behind us an unwieldy piece of history: a solar panel off the roof of the Carter White House. It’s decades old, though it still makes hot water just fine. In a sense, we’re traveling backward—which in another sense is what I think we’re going to have to do for a while in the U.S. climate movement.
