U.S. Climate Resilience Toolkit. Wat€r Mu$ic. Les installations hydroélectriques produisent environ 14 % de l’énergie électrique en France, avec de fortes variations saisonnières en fonction de l’hydraulicité.
Malgré d’importantes disparités entre pays, le pourcentage moyen est du même ordre au sein de l’Union européenne et dans le reste du monde. Mais l’importance de cette technologie dépasse la dimension purement quantitative de sa production. En effet, la flexibilité des centrales donne à l’énergie hydroélectrique un rôle essentiel pour répondre à la versatilité de la demande et des sources d’énergie intermittentes. A New Mode for Transportation Where There Are No RoadsTEDCity2.0. La disparition. Le 30 novembre 2014, le géant énergétique allemand E.ON a surpris la plupart des observateurs de l’industrie en annonçant qu’il se séparait de ses activités traditionnelles de production d’électricité en Europe pour se concentrer sur les réseaux, les énergies renouvelables, et les services aux consommateurs.
Cette annonce marque effectivement la disparition d’un géant énergétique européen, dont l’histoire se confond avec celle de la libéralisation de l’industrie électrique en Europe. Ce billet en tire les enseignements principaux. La naissance d’un géant A la fin des années 1990s, les gouvernements européens ont conjointement adopté des mesures visant à libéraliser les industries électriques et gazières.
Would we benefit from climate insurance? Scientists agree that climate change will have negative consequences, but there is enormous uncertainty regarding the extent of the damages.
Civilization-threatening climate events such as runaway global warming or extreme sea level rise may not be likely over the next century, but they also cannot be ruled out. Yet, when economists estimate the monetary benefits of climate change policies, it is common to ignore the role that climate policy plays as insurance against the possibility of catastrophic events.

The EU Emissions Trading System (EU ETS) Kyoto Protocol 'loophole' has cost $6 billion - environment - 09 February 2007. A loophole in an important part of the Kyoto Protocol has cost nearly $6 billion, suggests new research.
The loophole will now be closed, say officials. The problem relates to the Clean Development Mechanism (CDM). 42 Issues in the Design of Environmental Excise Taxes.pdf. Value of life. The potency of life (or cost of life) is an economic value assigned to life in general, or to specific living organisms.
 In social and political sciences, it is the marginal cost of death prevention in a certain class of circumstances.  As such, it is a statistical term, the cost of reducing the average number of deaths by one. It is an important issue in a wide range of disciplines including economics, health care, adoption, political economy, insurance, worker safety, environmental impact assessment, and globalization.
Urbanization Project. The Charter Cities initiative works with governments in rapidly urbanizing countries, focusing on the potential for startup cities to fast track reform.
Eco - Green tax. Green Business. Why should we trust scientists, anyway? Australia is repealing its controversial carbon tax. The carbon-tax experiment in Australia is now over.
Economists tend to prefer carbon pricing for tackling global warming On Wednesday, the Australian Senate voted 39-32 to repeal the nation's controversial tax on greenhouse-gas emissions. The tax, first passed in 2011, had charged people roughly $23 for every ton of carbon-dioxide they emitted from oil, coal, or gas. The repeal is a big blow for climate policy. Economists have long argued that carbon pricing is one of the most effective ways to tackle global warming. Why the U.N. climate talks keep breaking down, in five simple charts. It's now the second week of this year's international climate negotiations in Warsaw and things ... aren't going well.
Protestors at the Warsaw climate talks. (AP) "An old rift between rich and poor has reopened in U.N. climate talks," the AP reports, "as developing countries look for ways to make developed countries accept responsibility for global warming — and pay for it. " In short: Poor countries argue that richer countries are responsible for most of the carbon-dioxide already the atmosphere, so they should pay for the damage caused by global warming. CarbonWeb - CarbonWeb.pdf. Where do greenhouse-gas emissions come from? - Everything you need to know about global warming.
It depends on how much the planet actually heats up.
The changes associated with 4° Celsius (or 7.2º Fahrenheit) of warming are expected to be more dramatic than the changes associated with 2°C of warming. Welcome to Carbon Atlas. Montomery_testimony_0714.pdf. MIT Thinks It Has Discovered the Perfect Solar Cell. A new MIT study offers a way out of one of solar power's most vexing problems: the matter of efficiency, and the bare fact that much of the available sunlight in solar power schemes is wasted.
The researchers appear to have found the key to perfect solar energy conversion efficiency—or at least something approaching it. Corporate Average Fuel Economy. CAFE Standards Reach Prius Levels 25 Years After Its Introduction Starting in 2011 the CAFE standards are newly expressed as mathematical functions depending on vehicle "footprint", a measure of vehicle size determined by multiplying the vehicle’s wheelbase by its average track width. A complicated 2011 mathematical formula was replaced starting in 2012 with a simpler inverse-linear formula with cut-off values.  CAFE footprint requirements are set up such that a vehicle with a larger footprint has a lower fuel economy requirement than a vehicle with a smaller footprint. CAFE has separate standards for "passenger cars" and "light trucks", despite the majority of "light trucks" actually being used as passenger cars.
The National Highway Traffic Safety Administration (NHTSA) regulates CAFE standards and the U.S. Environmental Protection Agency (EPA) measures vehicle fuel efficiency. Summary of Roll the DICE Again: The Economics of Global Warming. WGI AR5 Chapter Template - SYR_AR5_LONGERREPORT.pdf. Stanford University Roundtable. National Renewable Energy Laboratory (NREL) Home Page. Sivens, un drame de la décision publique à la française.
Le drame de Sivens a révélé les faiblesses de l’organisation de la décision publique en France. La décision de construire le barrage dépend du rapport de force politique local, ce qui a fini par déboucher sur des affrontements violents entre agriculteurs et écologistes. The cost of wind and solar power keeps dropping all over the world. Many people have probably heard that it's getting cheaper to install rooftop solar panels in the US.
