Recently I read that our challenge in the twenty-first century is to triple global energy demand “so that the world’s poorest can enjoy modern living standards, while reducing our carbon emissions from energy production to zero”.

  In Minneapolis, the Trust for Public Land (TPL)’s highest-rated big city for public parks, 95 percent of residents (including roughly the same portion of low-income residents) live within a ten-minute walk of a city park.  But in Charlotte, the...

Rhine-Ruhr, or Essen-Düsseldorf, is among the world's least recognized larger urban areas (Figure 1).  Germany does not designate urban areas according to the international standard, and for that reason the Rhine-Ruhr does not appear on the United Nations list of largest urban areas. Yet, in reality this contiguous urban area is Germany's largest urban area, a position as it has held since at least the end of World War II. The Rhine-Ruhr is the third largest urban area in Western Europe, trailing only Paris and London. The area was one of the strongest early urban industrial areas in the 18th century and continued as a major manufacturing and coal mining center through the first half of the 20th century.

Why does PRADAN support small decentralized farm-based rainwater harvesting rather than big projects? In short, we made a commitment to poor, small-holder farmers to ensure happy, self-sustainable livelihoods in their own farms. Fifty seven percent of Indian rural households own some land, the majority of farms less than one hectare and about half depend entirely on seasonal rain [1]. Many of these farmers do not have access to irrigation projects tied to big dams and government-sponsored canal programmes.

The above map shows the levels of food insecurity in America. The darkest areas on the map mean that at least 30 percent of that area's population is food insecure. While the lightest areas are between 4 and 14 percent.

New research suggests LEED-ND-certified buildings dramatically cut down on driving rates.

Last week, EPA released the fifth drinking water infrastructure needs survey and assessment. This survey indicates that $384 billion is needed to invest in things like pipes, treatment plants and storage tanks to meet the needs of 73,400 water systems across the country over the next 20 years. This huge need represents challenges to delivering safe drinking water to homes and businesses, especially as we face aging infrastructure worldwide.

Is there a store in your city that offers products made out of recycled materials? Are there grocery stores that sell local and organic foods?

“The move to the smart grid is impossible to achieve in one big operational mass,”...“Breaking it into bite-sized pieces — this is the future of the microgrid market.”

From northern Europe to Florida, highway planners are rethinking roadsides as potential habitat for native plants and wildlife. Scientists say this new approach could provide a useful tool in fostering biodiversity.

Seattle City Light and the Bullitt Foundation have announced a first-of-its-kind model for financing advanced energy-efficiency improvements in new and existing commercial buildings.

The model has to key differentiators from typical financing plans. First, an energy-efficiency meter measures real-time energy savings and allows it to be sold as it occurs. Second, a 20-year contract is inked between the utility and energy-efficiency investors.

A great example of how green infrastructure can be incorporated from the start in new street design.

Permaculture is notoriously hard to define. A recent survey shows that people simultaneously believe it is a design approach, a philosophy, a movement, and a set of practices. This broad and contradiction-laden brush doesn’t just make permaculture hard to describe. It can be off-putting, too.
