This isn’t surprising as I already noted that America could cut its coal consumption by 62 % by 2020 just by increasing its energy efficiency. Now comes a new study that shows that the USA could be completely coal-free by 2030. If it can be done in America, it sure can be done in the European …
This is not news as we have seen it in Sustainable energy – without the hot air but some facts need reminders. The internal combustion engine – like incandescent light bulbs – is extremely inefficient. To GOOD : If you had to invent an efficient way to move (…), you could hardly do worse than …
I wrote about it before : deforestation in the Brazilian part of the Amazon rainforest – aka the lungs of Earth – decreased by no less than 46 percent and is at record low levels in the past two decades. These are surely good news as deforestation is a predominant part in Brazilian greenhouse gases …
As the world is heating up because of global warming we need more air conditioning systems. This is why the latest invention from the U.S. National Renewable Energy Laboratory may change the world. Indeed, to the MIT Technology Review, the NREL have created ” a new air-conditioner design that (…) will dramatically increase efficiency and eliminate …
According to GreenTech Media, Ocean Thermal Energy Conversion is after wave and tidal energies the third form of ocean power. Albeit it was discovered a century ago, there have been few attempts at tapping this energy source. To Wikipedia, OTEC ” uses the temperature difference that exists between deep and shallow waters to run a heat …
Last month the founder of Microsoft gave a speech on low carbon energy and climate change at TED, a renowned event on Technology, Entertainment and Design. To Mr. Gates we need five means : carbon capture and storage, nuclear power and renewable energies (solar PV, Concentrated Solar Thermal and Wind power). I agree with that. …
While having a look at the RSS feed of TreeHugger I found something that made me smile : How Australia Could Be Carbon Neutral in 10 Years. Let’s be honest : it really can’t be done. Let’s see why here. The plan outlined by Beyond Zero Emissions states that all the energy consumed in the country …
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 …
