EPA to regulate greenhouse gases emissions

We had reason to be optimistic on the Copenhagen Climate Conference as the United States unveiled on the first day a plan that will allow its Environmental Protection Agency to act on greenhouse gases emissions. Among the gases that will be regulated are carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride. As you …

Can we stop relying on fossil fuels by 2030 ?

Scientific American published in this month’s issue an article on how the world could completely stop relying on fossil fuels (coal, oil, natural gas and nuclear) by 2030 and use only solar, wind and water energies. To make a long story short and after reading the various critics this is completely impossible. We can go …

Old nuclear weapons generate electricity

According to the New York Times around 10 percent of the US electricity is provided by old nuclear bombs, including Russian ones. I find very inspiring that weapons once targeting houses are now powering them. These agreements concern thousands of warheads and are part of a non proliferation policy enacted by both countries. With up …

Storing solar electricity with molten salt

One of the main hindrances of solar energy is that when there is no more sun, there is no more electricity as well. This problem is being solved with the molten salt technology which stores energy for seven hours. A Californian company is willing to build a 150 Megawatt plant – The Rice Solar Energy …

The United States is a food wasteland

This is the catchy title of an article GOOD recently published. It is not entirely new to me as I previously wrote about it, but the data provided there undoubtedly has to be shared. Here goes the beginning of  the article : ” When it comes to food, Americans are the undisputed champions of one …

Could America tax gas more and fund cleantech?

For my latest post for CleanTechies I propose a reflection further to an interesting op ed Thomas L. Friedman wrote on the New York Times on why America should tax more gasoline. As I noted earlier US drivers pay less than ten euro cents per liter of tax when their German, British, Italian, Turkish or …

Carbon Capture and Storage works !

Alstom and various US partners have been testing carbon capture on a small Wisconsin coal-fired plant. After a year of testing, this pilot project is a success as 90 percent of carbon dioxide was captured. The French company is willing to commercialize CCS for new and existing coal fired plants as early as 2015. But …

America is going forward on climate change

America is the world’s second largest greenhouse gases emitter and thus needs to act. It seems it is the case as the local Environmental Protection Agency (EPA) may cut emissions from the energy and industry sectors as early as 2011. This is good news as 70 percent of US emissions come from them. Additionally, the …

Battery breakthroughs for electric vehicles

Many are working on extending the range of electric cars. Here are three of them. Firstly TreeHugger believes that replacing the  graphite electrodes in lithium-ion batteries with silicon nanotube electrodes,would multiply the range by ten. ArsTechnica notes that carbon nanotubes in ultracapacitors ” may make sense in electric cars, even if it can’t store as …

We still are funding fossil fuels industries

After the quite encouraging news of Wednesday I would like to present you a study showing that the United States’ government still gives much more money to polluting fossil fuels industries rather than lower carbon solutions. This occurs as I noted last year than to the UNEP  cutting the subsidies given to big oil and …
