Central versus distributed storage has been an ongoing debate. Each has its pros and cons. There are instances where the advantage of one over the other is obvious — such as central bulk storage at geological sites where caverns or water reservoirs with different elevations are almost readily
If you’re like most renewable energy advocates that have interacted with a Public Utilities Commission, you probably don’t think they’re a repository of progressive policy toward distributed renewable energy. In general, you’re right. But it’s worth sharing a few,
We can fly, drive and prosper while avoiding dangerous global warming – but only if billions remain in poverty and huge changes are made in areas such as energy and agriculture, new analysis from Decc’s Global Calculator shows
Declining pollinator populations could leave as many as half of the people in developing countries facing nutritional deficiencies, according to researchers from the University of Vermont and the Harvard School of Public Health. In the study — the first to link pollinator declines directly to human nutrition — researchers collected detailed data about people's daily diets in parts of Zambia, Mozambique, Uganda, and Bangladesh. They found that in Mozambique, for example, many children and mothers are barely able to meet their needs for micronutrients, especially vitamin A, which is important for preventing blindness and infectious diseases. Fruits and vegetables were an important source of that nutrient for many people in the study, and those crops are highly dependent on pollinators, researchers say — for example, yields of mangoes, which are high in vitamin A, would likely be cut by 65 percent without them. Pollinator losses might also lead to folate deficiency, they say, which is associated with neural tube defects.
There is an impression, both in the press and among some urban analysts that as cities become larger they become more densely populated. In fact, the opposite is overwhelmingly true, as Professor Shlomo Angel has shown in his groundbreaking work, A Planet of Cities. This conclusion arises from the fact that, virtually everywhere, cities grow organically so that they add nearly all of their population on the urban fringe, which has considerably less expensive land. As their physical form of cities (the urban area) expands, the residents per unit of developed area generally falls.
The concept of the precariat, from Wiktionary: “People suffering from precarity, especially as a social class; people living a precarious existence, without security or predictability, especially job security.”
We will switch away from fossil fuels sooner or later, because they will run out. If it's later, our kids get a wrecked civilization trying to cope with a wrecked climate. This week on Radio Ecoshock we finish out a three-part series on alternative energy, what it can do, and what it can't.

Bradley Calvert at Family Friendly Cities has done some impressive number-crunching to identify trends in where families with children are living. Using Walk Score and Census data, he analyzed the 50 largest metro areas in the U.S. to determine whether the population of children is growing or shrinking in walkable and unwalkable areas. (Some regions had to be excluded because they didn’t have any places with a Walk Score over 70.)
It seems pretty obvious that recycling, reusing, and repurposing materials we no longer need makes a lot more sense than burning or burying them, not just from an environmental, but an economic perspective.
