Improving the sustainability of water treatment systems: Opportunities for innovation

by

There is growing recognition of the need for increased access to drinkable water across the world and for water treatment approaches that improve the quality of the delivered water and re-establish a balance between human and natural systems…Localized, networked water treatment systems improve access to potable water, encourage the development and diffusion of innovations through reduced financial and technical risks, lower the potential of total system failure, and provide easier trial and replacement of specific innovations and greater organizational capacity.

Introducing the “Post Carbon Reader”

by

In 2009, Post Carbon Institute recruited 29 of the world’s leading sustainability thinkers to answer one fundamental question: How do we manage the transition to a more resilient, sustainable, and equitable world? Like us, our Fellows see five key truths:

  • We have hit the “limits to growth.”
  • No issue can be addressed in isolation.
  • We must focus on responses, not just solutions.
  • We must prepare for uncertainty.
  • We can do something.

Totnes Energy Descent Action Plan website launched today!!

by

It gives me the greatest pleasure this morning to launch the Totnes Energy Descent Action Plan website. The site makes the full version of the UK’s first EDAP freely available, invites comments and discussion, and will act as a dynamic portal for people to discuss the Plan and reshape subsequent revisions.

China’s coal bubble…and how it will deflate U.S. efforts to develop “clean coal”

by

The conventional wisdom in energy-and-environment circles is that China’s economy, which is growing at a rate of eight percent or more per year, is mostly coal powered today and will continue to be so for decades to come…Most of this conventional wisdom is correct, but some of it is plain wrong—so wrong, in fact, that environment-, economic-, and energy-policy wonks are constructing scenarios for the future of U.S. and world energy, and for the global economy, that bear little or no resemblance to the reality that is unfolding.

The peak oil crisis: China’s latest drought

by

There will be at least three major consequences of recurring drought conditions in southwestern China. First will be that millions of people and head of livestock will have to find a source of water or move. Next comes the food supply. The third problem of a lasting drought is the collapse of hydro-generated power in China. Should the hydro-power shortages continue for long we can expect that higher oil imports and world prices will not be far behind.
