Public transportation holds key for cleaner city, fights against climate change

A bus in Dubai - public transportation can go a long way in sustainability and climate stability.

It may seem clear, but you need a study to have certainty: public transportation is cheap and “green”. A recent research concluded that effective public transit systems can provide a cost-effective solution to fighting global change at a global level. If public transits are improved throughout the entire world, the report shows that urban transportation could be cut by more than half by…

A new method of producing hydrogen has been reported by researchers at University of Glasgow that’s 30 times faster than current state-of-the-art methods, providing yet another advance that might one day lead to a sustainable hydrogen based economy. There’s only so much that renewable energy can grow with today’s infrastructure due to base load considerations. If the intermittency can be…

Stanford scientists split water with device that runs on an ordinary AAA battery

14193-splitter_device

Researchers from Stanford have found a way to split water into oxygen and hydrogen using very little energy; the hydrogen they obtain could be used to power fuel cells in zero-emissions vehicles. I’m quite excited for cars that run on hydrogen, which are set to hit the market in 2015; but while they are always presented as “zero emission cars”, many of…

Wind Turbine Syndrome? Legal courts aren’t buying it

assets-climatecentral-org-images-uploads-news-8_20_14_upton_wind-turbine-and-house-500x410

After digging around on several articles and editorials, I still haven’t found an exact, concise definition of what Wind Turbine Syndrome is. It is not recognized by any international disease classification system and does not appear in any title or abstract in the massive US National Library of Medicine’s PubMed database. From what I could find, it has no scientific basis,…

New insights on photosynthesis bring us one step closer to solar fuels

Scientists have determined the exact structure of an important photosynthesis complex at a crucial stage. Photo: Shutterstock

For billions of years, nature has been harnessing the energy from the sun through photosynthesis. This way, plants, algae and cyanobacteria use sunlight to split water and produce energy-rich chemical compounds from carbon dioxide (CO2). This energy is then transferred to animal that eat these plants, and animals that eat plant-eating animals, including us humans. It’s clear that without photosynthesis, there…

Chinese coal consumption just fell for first time this century

2014-08-18-china1-thumb

We’re used to reporting year after year how China’s coal consumption is increasing and how they are polluting more and more. But this is the first year in over 2 decades when the number hasn’t increased. Could China’s coal boom be over? While positive signs have been emerging from China for well over a year, it appears the ‘war on…

Lead-acid car batteries used to be the norm, but luckily we’re seeing a massive shift towards more efficient and environmentally friendly alternatives like lithium-ion. Still, there are fleets of hundreds of millions of cars that still employ these archaic and toxic batteries. Typically, manufacturers try to have car owners bring their old lead-acid batteries, which are then converted into more…

Why Australia’s biggest oil discovery in 30 years doesn’t matter

o-TONY-ABBOTT-facebook

I was reading this morning how excited some journalists were in reporting “the biggest oil discovery in decades”, and I got a little curios: how big is it? According to US oil company Apache, the field could have potentially up to 300 million barrels of oil in place – Australia gets a lot of oil, stock prices for Apache surge,…

A new study conducted by Stanford Researchers demonstrates a practical “roadmap” for converting California’s all-purpose energy infrastructure over to renewable sources by 2050. The paper proposes running the state on a mixture of wind, water and sunlight (WWS). To make things even more interesting, the paper does it all with available technologies – of course, it is extremely likely that…
