What a Utility of the Future Might Look Like

What a Utility of the Future Might Look Like | Sustainable ⊜ Smart Path | Scoop.it

Transformation of the ageing electric power grid in the US is inevitable and urgent; most people in the energy industry can agree on that.

 

In the absence of federal energy policy that will shape the electric power industry in the decades to come, utilities such as Duke are transforming the country's energy infrastructure from the ground up.

 

In 2007, Duke Energy received approval from the Indiana Utility Regulatory Commission to build a cleaner-coal integrated gasification combined cycle (IGCC) plant at the Edwardsport site. Cost $2.595bn.

 

Althoug this is progress but with no country wide coordination, is this the the best solution - coal  power plan at cost of $2.6 Billion?  How  many wind or solar plants we could develop in  $2.6 Billion?

Collective Intelligence: Cities as Global Sustainability Platform

Warren Karlenzig - Social media and collaborative technologies--layered with smart systems combining geo-location data with human experience--will make cities the driving sustainability force in a dawning planetary era.

Global Fuel Economy

Global Fuel Economy | Sustainable ⊜ Smart Path | Scoop.it

MORE than half the world's oil supply is used for transport, and three-quarters of the energy used in transport is spent on the road.  

 

But without new policies to spur efficiency, the amount of fuel used for road transport will double by 2050, with severe implications for carbon-dioxide (CO2) emissions.

 

Most of the technologies needed to improve fuel economy are already available and cost-effective, so what is needed are policies that steer businesses and consumers in the right direction.

 

Fuel-economy standards, taxes, CO2-based vehicle taxes, and better product labelling are the four key policies recommended by the IEA. To judge the extent to which countries have adopted these, the IEA has created a fuel-economy readiness index (see map). Many advanced countries, especially in Europe and Japan, already have the right policies in place, whereas in North America there is still room for improvement.

The Sky Is the Limit for Wind Power: Scientific American

The Sky Is the Limit for Wind Power: Scientific American | Sustainable ⊜ Smart Path | Scoop.it

The amount of power to be reaped from tapping low- and high-altitude winds dwarfs global demand.

 

Wind turbines on land and offshore could readily provide more than four times the power that the world as a whole currently uses. Throw in kites or robot aircraft generating electricity from sky-high winds and the world could physically extract roughly 100 times more power than presently employed—and the climatic consequences remain minimal. 

 

Two new computer-model analyses suggest there are few limits to the wind's potential. Although "there are physical limits to the amount of power that can be harvested from winds, these limits are well above total global energy demand," explains climate-modeler Kate Marvel of Lawrence Livermore National Laboratory.
