Community groups and businesses that value environmental stewardship are building their reputation and earning cash through a unique partner program. Clean Energy Collective (CEC), a community solar developer with projects in eight states, is building a nationwide network of partners that
Online social media have greatly affected the way in which we communicate with each other. However, little is known about what are the fundamental mechanisms driving dynamical information flow in online social systems. Here, we introduce a generative model for online sharing behavior and analytically show, using techniques from mathematical population genetics, that competition between memes for the limited resource of user attention leads to a type of self-organized criticality, with heavy-tailed distributions of meme popularity: a few memes "go viral" but the majority become only moderately popular. The time-dependent solutions of the model are shown to fit empirical micro-blogging data on hashtag usage, and to predict novel scaling features of the data. The presented framework, in contrast to purely empirical studies or simulation-based models, clearly distinguishes the roles of two distinct factors affecting meme popularity: the memory time of users and the connectivity structure of the social network.

We may be getting closer to integrating the science of agroecology and the science of nutrition, toward a holistic approach that would follow nutrients from the soil, to plants and animals, to human bodies.
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,
In a complex adaptive system we have dispositionality not causality, so when we act we cannot know what will happen. That means we need to maintain the ability to respond quickly, something I brought in at the end when I talked about complexity approaches to project management.
What ultimately matters to people’s well-being? In this blog, Terra Lawson-Remer looks beyond gross domestic product and analyzes a number of core economic and social measurements to determine human progress.
All our great ideas about climate change, peak oil, re-localization, etc. are worthless if we can't communicate with other people. It's easy to get into gridlock and name-calling even with people who should be our allies.
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.
