The States And Cities That Lead (And Lag) In The Clean-Tech Economy

The States And Cities That Lead (And Lag) In The Clean-Tech Economy | Développement durable et efficacité énergétique | Scoop.it

When it comes to clean tech, America could do with some Californication. The state is beating everywhere else hands down, from public policy and capital invested to adoption of electric vehicles and smart meters.


A new ranking of clean-tech leadership from research firm Clean Edge gives the Golden State a score of 91.7 out of 100. The next highest ranked state, Massachusetts, comes in with a score of 77.8. Clean Edge’s state scores combine 70 indicators, while the metro scores look at 20 factors, including things like green buildings and levels of clean electricity.

Map of the Day: Where Americans Use the Most Oil

Map of the Day: Where Americans Use the Most Oil | Développement durable et efficacité énergétique | Scoop.it
3.5 percent of U.S. counties consume more than 10 percent of the nation's oil.

America consumes a lot of energy. Counties play a large role in this overall consumption — and many of them contain large cities like Los Angeles and Chicago.

Deron Lovaas, the federal transportation policy director for the Natural Resources Defense Council, posted a map charting oil consumption by county on the NRDC staff blog Thursday.

The map is the product of a joint research effort of the NRDC, the Sierra Club, and the League of Conservation Voters to identify the most oil dependent locations across the United States.


As shown in the map (and accompanying list of national averages), oil consumption is geographically uneven and highly concentrated. Lovaas notes that "just 108 counties out of the nation's 3,144, or about 3.5 percent of the total consume more than 10 percent of the nation's oil." Not surprisingly, Los Angeles county had the most annual oil consumption, at nearly 1.9 billion gallons in 2010. Harris county, Texas, follows with 1.7 billion gallons, and Cook county, Illinois, takes third with 1.6 billion.

The Hestia Project Maps Carbon Emissions of US Cities Down to Street Level

The Hestia Project Maps Carbon Emissions of US Cities Down to Street Level | Développement durable et efficacité énergétique | Scoop.it
A team of researchers from Arizona State University have developed a new software system, called Hestia, that is capable of estimating greenhouse gas emissions across entire urban landscapes, all the way down to street level and individual buildings.

The project, known as Hestia after the Greek goddess of home and hearth, allows the team to combine extensive public database “data-mining” with traffic simulation and building-by-building energy-consumption modeling.

According to researchers, Hestia’s increased detail and accuracy will help cities, and possibly even other nations, identify where an investment in energy and greenhouse gas savings would have the greatest impact...
