Australia could realistically go 100% renewable energy in 10 years

The only thing that stands between Australia and a future led entirely by renewable energy is the political will to make the change, a new report claims. Australia could be powered entirely by renewable energy in no more than 10 years, using solar and wind energy – two resources which Australia has a lot of. The report was released by

U.S. centered climate change report acknowledges human influence and tells of grim future

A draft released by the U.S. National Climate Assessment reports how human-induced climate change has caused far reaching consequences far dire than previously estimated, affecting all regions of the U.S. “Corn producers in Iowa, oyster growers in Washington State, and maple syrup producers in Vermont have observed changes in their local climate that are outside of their experience,” the report said.

Princeton nanomesh greatly increases the efficiency of organic solar cells

While we all have to recognize the huge potential that solar energy brings us, we also have to say that sadly, so far, we’re not very effective at harnessing this energy. The best modern silicon and indium-tin-oxide-based solar cells are approaching the theoretical limit of 33.7% efficiency. A big breakthrough The team led by Stephen Chou made two dramatic improvements:

Wikileaks reveals US bribes and cyber-espionage stop climate change action

Negotiating an official climate change pact is an extremely high-stake game, not only due to the threats posed to our entire civilization, but also because re-engineering the global economy to a low-carbon model will redirect a massive, multi billion dollar sum towards different sources. Of course, behind all the “save the planet” rhetoric lies the mucky realpolitik: money and threats

Wave-powered swimming robots completes epic 9,000 journey at sea

After it was first cast out to sea less than a year ago from San Francisco’s bay, the PacX Wave Glider, also known as Papa Mau, finally reached the end of its epic journey after it reached Queensland, Australia setting a new world record for the longest distance traveled by an autonomous vehicle. PacX swam over 9,000 miles. Designed for data

Exclusively solar-powered plane will circumnavigate globe in a non-stop flight, even at night

Solar Impulse, the now famous 100 percent solar-powered aircraft, made the headlines after it proved it could fly for 26 hours straight, be it day or night. Now the projects’ initiators want to take the plane and solar power to new dazzling heights – they want to circumnavigate the globe in 20 days and 20 night flight all powered by

Nanoparticle-tech converts solar energy into steam with extreme efficiency

While current solar energy conversion technology is preoccupied with generating electricity with as much efficiency as possible, researchers at Rice University have invented a new technological set-up consisting of nanoparticles smaller than the the wavelength of light that can transform solar energy into steam almost instantly. Their findings show a registered efficiency of 24%, while current solar panel standards range at

World Bank worries about global warming

When the first major talks about global warming began, a top margin of 2 degrees was set for 2100, people slowly understood the globe is warming up much faster than previously expected, so the limit was pushed – first to 3 degrees, now to 4 degrees – and even this isn’t certain.   So heat waves and droughts should be

First wooden wind turbine installed in Germany is a lot more eco-friendly

As of 2010 wind power amounted to 2.5% of the world’s energy production with an estimated 25% increase in quota each year. Yes, eolian  power is one of the cleanest forms of energy production, but like any other renewable sources, its no entirely all green. During a wind power turbine’s manufacturing hundreds of tons of steel are used, which translates

Transparent solar cells could be used onto entire buildings, screens, and more

This has the potential to be the holy graal of solar energy – UCLA researchers have developed a new organic polymer that produces electricity, is nearly transparent and much more resistant than silicone. If you think about solar cells, usually, the blacker the better – the blacker they are, the less energy is lost. But what if we could make

Four teenage girls create device that turns pee into electricity

14-year-olds Duro-Aina Adebola, Akindele Abiola, Faleke Oluwatoyin, and 15-year-old Bello Eniola have created a urine power generator, which can “turn one liter of urine into six hours of electricity”. I’m not really sure what “six hours of electricity means”, and I couldn’t find any additional details, but I guess it’s a little more than keeping a light bulb turned on.

Team develops side-illuminated ultra efficient solar cell design

The new architecture, depicted in the picture below can exceed a 40 percent conversion efficiency, and even when irradiated from the side it generates solar conversion efficiencies that rival, and may eventually surpass, even the most ultra-efficient photovolataics. The new cell was developed by researchers working on the David Ben-Gurion National Solar Research Center, and they can reach and even

First all-carbon solar cell promises to lower industry cost

Scientists at Stanford University have successfully devised the world’s first solar cell made entirely out of carbon. This alternative to typical silicon solar panels is not only a lot cheaper to produce, but also a lot less simpler to use. Such carbon cells can be coated on any surface and turn it into a solar panel, be it windows, roof

Coal energy slowly becoming more expensive than wind

I recently came across a great article written in the Washington Post which really gives some insight about the economics behind wind power and coal power. If you happen to listen to the more politicized or economic discussions, you’ll probably notice that the ball is thrown into the field of natural gas: many believe that low fortune of coal companies

Architects reveal plan for China’s first self sufficient, carless city

Most people perceive China as a greatly polluted, overcrowded country, with little to no interest in renewable energy and a sustainable future. But that legacy is changing. Chicago-based architects Adrian Smith and Gordon Gill have unveiled plans for Chengdu Tianfu District Great City, a self sustainable satellite city which offers insightful solutions to the crowded infrastructure, murky traffic and great

Military scientists announce they are close to turning seawater into jet fuel

According to their own statements, the US Naval Research Laboratory is working to extract the carbon dioxide and produce hydrogen gas from the seawater; if everything works out fine for them, they will be able to convert the CO2 and hydrogen into hydrocarbons which will be used as jet fuel.   Of course, the main interest is a military strategic one:

Electric cars are twice as harmful than conventional cars to the environment during manufacturing

There’s a general belief, most likely resulting from extensive marketing ploys, that electric cars are the cleanest mean of transportation, and an adoption should be hastily made in order to save our planet. While it’s true that electric cars have virtually zero emissions and not even one part per million of CO2 is released during operation, a new research by scientists at

The real reasons why American CO2 emissions dropped this year

This year, we witnessed the United States’ carbon emissions drop to a record level, one that hasn’t been seen in the last 20 years. Lots of people started shouting and spreading misinformation, claiming that renewable energy and all those green measures were responsible for this remarkable feat. It would be great if this were true but sadly… it isn’t. Hydraulic

Eco Basics: Benefits From Installing Home Solar Panels

Installing solar panels at your home or business give you many benefits. These benefits range from feeling better about your impact on the environment to monetary ones. Combined with the fact that solar technology is falling in price, these benefits could be very tempting to those looking reduce costs and do more for the planet. Helping the Environment Solar energy

Pacific island nation Tokelau to become first entirely solar powered nation in the world this year

Tokelau is a small island near Samoa, not far from New Zealand; at a first glance, it wouldn’t seem significantly different from other beautiful atolls in that part of the world, but Tokelau has something very special: they are on track to become the first territory entirely powered by solar energy. The Diesel dependent country will rely on solar energy
