New Energy Strategy for Minnesota Evaluates Renewables

A new article in the RMI Outlet looks at a comprehensive evaluation in Minnesota to assess the value and potential of renewable energy resources to replace the infrastructure heavily dependent on fossil fuels. The move has elicited some corresponding excitement from businesses in the state.
And it is not just Minnesota’s government building momentum around an alternative energy future. The state’s Fortune 100 companies, such as Target and Best Buy, have set significant GHG reduction goals. Its power companies continue to expand renewable generation, including both solar and wind. And Minnesota’s civil society, pillared by organizations such as Great Plains Institute and Center for Energy and Environment, helps facilitate change and drive innovation in the energy and efficiency sector. That is why RMI was excited to support the Minnesota Department of Commerce in the development of a comprehensive guide to conducting an energy future study for Minnesota.
You can imagine that somewhere in the faraway, fictional land of Lake Wobegon, solar panels are appearing atop barn roofs and wind turbines are gracing ridge lines.

NASA Study Points to Collapse of Civilization

A new study funded by NASA suggests that we're facing the collapse of industrial civilization within decades due to a combination of factors evaluated using a cross-disciplinary model, HANDY (Human And Nature DYnamical). Factors that were weighed in the study include: population, climate, water, agriculture, and Energy. Rather than being a rare occurrence, the study points to earlier historical precedents that show that "precipitous collapse" has been common in human history and the results often last centuries. The study has been accepted for publication in the peer-reviewed Elsevier journal, Ecological Economics

In evaluating the factors using the HANDY methodology, the study noted:
These factors can lead to collapse when they converge to generate two crucial social features: "the stretching of resources due to the strain placed on the ecological carrying capacity"; and "the economic stratification of society into Elites [rich] and Masses (or "Commoners") [poor]" These social phenomena have played "a central role in the character or in the process of the collapse," in all such cases over "the last five thousand years."
Will technology save us? The authors were skeptical:
"Technological change can raise the efficiency of resource use, but it also tends to raise both per capita resource consumption and the scale of resource extraction, so that, absent policy effects, the increases in consumption often compensate for the increased efficiency of resource use."
The conclusion: our "business as usual" approach cannot be sustained and governments, corporations, and consumers need to adapt and change to keep our worldwide civilization intact and functioning.

Energy Solutions—Amory Lovins Speaks at Bioneers

The annual Bioneers conference is often a revelation to attendees, offering fresh, pragmatic, sustainable solutions to the social, cultural, and environmental problems of our age. The last conference included a keynote address from Amory Lovins, the cofounder, chief scientist, and chairman emeritus of the Rocky Mountain Institute. It's worth viewing—the talk summarizes many of the key ideas of Reinventing Fire, Bold Business Solutions for the New Energy Era.

Watch for a YouTube posting of Lovins' talk at TED2014: The Next Chapter, to be held in Vancouver, BC, Canada this next week.

Brighter Streetlights, Less Energy

As reported by the Earth Island Journal, a shift from traditional streetlights to light-emitting diodes bulbs is being instituted by cities in locales around the country, from San Antonio to San Francisco. 
Energy savings from this conversion are already showing benefits. Quoting from the article:
In terms of the environment, LEDs definitely bring some benefits, the biggest of which is energy savings. The Oakland Streetlight Conversion Project will save the city nearly $20,000 per year in energy costs, and will reduce city greenhouse gas emissions by approximately 40 percent (or 80,000 pounds) per year. “The overall goal of this whole project was to have better light in our city streets,” says Kristine Shaff, a public information officer with the City of Oakland. “And the energy savings are tremendous.”
One catch, noted in the article, blue-rich LEDs have the potential to disrupt circadian rhythms in animals and humans, so municipalities are encouraged to install yellow-rich LEDs to eliminate the concern.
