Fuel-Efficiency Standards Have Costs of Their Own

Fuel-Efficiency Standards Have Costs of Their Own | Développement durable et efficacité énergétique | Scoop.it
Some economists say that new fuel-efficiency standards for cars and trucks will do less good for the environment than a straight tax on gasoline.

 


By Eduardo Porter, NY Times 


 


"The rules are a significant step in the battle against global warming. The Environmental Protection Agency and the National Highway Traffic Safety Administration, which developed the standards, said they will reduce our energy use by 12 billion barrels of oil and cut carbon emissions spewed by our cars, pickups and sport utility vehicles in half by 2025. They should also cut down on other forms of pollution, helping with problems like asthma and acid rain.


 


What the government didn’t mention is that these improvements come at a high cost for drivers, automakers and society in general. They could be achieved much more cheaply by raising taxes on gasoline to a level comparable to that of pretty much every other industrialized nation."

FEATURE: Japan's "smart cities" gear up for disasters | equities.com

Since power shortages following the triple disaster that hit Japan in March last year made people keenly aware of the need for better energy management, the concept of energy-efficient "smart cities" has been catching on in the country.

 

Ideas for such environment-friendly communities with state-of-the-art technologies are flourishing especially in the disaster-hit northeastern Tohoku region, as the government encourages businesses and municipalities to launch smart cities projects by offering subsidies to help spur recovery.

 

In addition to smart cities projects across Japan that had gotten underway before the March 11 earthquake and tsunami and the subsequent Fukushima nuclear crisis, around 50 initiatives have emerged to build efficient communities in Tohoku.

 

Among them, the Economy, Trade and Industry Ministry selected in April eight pioneer projects in Fukushima, Miyagi and Iwate prefectures as candidates to receive subsidies the ministry will provide by March 2016 to promote smart communities.

 

In a fiscal 2011 extra budget, the government earmarked 8.06 billion yen for such subsidies.

 

The eight initiatives aim at achieving optimal energy use through the introduction of clean energy sources, including those for Tohoku factories of major manufacturers such as Toyota Motor Corp. and Nippon Steel Corp. as well as a group of local seafood processing companies.

 

An existing smart city in Kashiwa, Chiba Prefecture, east of Tokyo, can serve as a model for those Tohoku projects still in the planning stage.

 

The 273-hectare community being developed alongside a train station in the suburban area can demonstrate various steps to enable its residents to sustain themselves in the event of blackouts caused by disasters and other contingencies.

 

The front-runner "Kashiwa-no-ha campus city project," undertaken by major real estate agency Mitsui Fudosan Co., has introduced solar- and wind-power generators and a 2,000-kilowatt storage battery and secures water supply by tapping groundwater.

 

The community developed on a former golf course will be completed in 2014 with high-rise housing complexes, university campuses, parks, a shopping mall and a hospital. Its total population including commuters will reach 26,000.

Le Japon annonce l'arrêt total de sa production nucléaire d'ici 30 ans

Le Japon annonce l'arrêt total de sa production nucléaire d'ici 30 ans | Développement durable et efficacité énergétique | Scoop.it

Le gouvernement japonais a annoncé, vendredi 14 septembre, l'arrêt progressif de la production nucléaire sur trente ans, dix-huit mois après l'accident de Fukushima qui a provoqué une catastrophe sans précédent dans le monde depuis Tchernobyl, il y a vingt-cinq ans.

Le Japon devient ainsi le troisième pays, après l'Allemagne et la Suisse, à faire part de son intention de stopper ses réacteurs depuis l'accident du 11 mars 2011 à Fukushima Daiichi, consécutif à un puissant séisme et au passage d'un tsunami géant sur la région.

Avant l'accident, l'énergie nucléaire représentait près de 30 % de la consommation de courant au Japon. Et les autorités prévoyaient d'augmenter cette part à 53 % d'ici à 2030.

North America is expected to witness the highest capex globally, with $254.3 billion, representing a share of 24.5% of the 2012 global total. Compared to a global average capex growth rate of 13.4%, North America is expected to witness a capex growth of 15.7%. The increase of unconventional oil and gas activities, especially the continuing exploitation ofshale oil and gas sites and the development of Canadian oil sands are the major drivers for these investments.

Neoliberalism, Degrowth and the Fate of Health Systems

"Degrowth recognizes that humanity’s access to the earth’s resources and services of the biosphere are constraints upon socioeconomic activity. It also holds that politics and economics cannot trump thermodynamic and ecological realities. It places the limits to growth and ecological overshoot at the center of the predicaments Homo sapiens confront. It connects to culture and political/economy through this root public policy question: How to equitably distribute a shrinking economic pie?"

 



"We developed our world economy with oil as our security against future debt, always able to borrow more with the ‘certainty’ that cheap oil would provide future income to pay it off.

… This is the fundamental truth that eludes our cornucopian economists: our economy functions on energy input, not money output. Without endless cheap energy you can’t have endless employment. Our infinite demand has hit the wall of finite resources…[xxix]

Timothy Garrett, a contemporary physicist, has developed a model of economic activity as a heat engine -complete with a coefficient of output- which, expressed in lay terms means the economy is dependent for its output on the amount of energy –not capital or money or labor- flowing into it."

Must-read analysis by Dan Bednarz and Allana Beavis on what "the end of cheap energy and growth" means for Western health systems.

Claiming The Clean Energy Future: A Seven-Point Action Plan For Repowering America | ThinkProgress

Claiming The Clean Energy Future: A Seven-Point Action Plan For Repowering America | ThinkProgress | Développement durable et efficacité énergétique | Scoop.it

Mitt Romney’s acceptance speech at the Republican National Convention last week ought to serve as an urgent wake-up call to anyone that cares about America’s energy, environmental, and economic future. At the podium, Romney chided President Obama on global warming, and his hoped-for GOP administration is advancing an “energy independence” plan built much more on the polluting industries of the past than the innovative clean technologies of the present and future. Somehow, global warming, renewables, and other clean-tech pursuits have become some of his favorite punch lines.

 

But clean tech is far from a laughing matter. Instead it’s the stuff of major multinationals such as GE, Toyota, and Siemens who are investing and making billions of dollars annually from their clean-tech initiatives; of startups including Tesla, SolarCity, and Agilyx who are respectively working to innovate electric vehicles, solar power finance, and plastics recycling; and of young Americans across our nation working to advance clean technologies, address climate change, and build thriving for-profit and non-profit ventures.

 

And contrary to what some would like you to believe, renewables energy production isn’t a marginal industry; it’s expanding rapidly in importance and penetration. In 2010 three states got more than 10 percent of their electricity generation from wind, solar, and geothermal. One year later, the number had doubled to six states including South Dakota and Iowa, which now generate approximately 20 percent of their total electricity from the wind alone. Clean tech isn’t shrinking; it’s starting to scale up to significant percentages for utilities, cities, states, and nations.
