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

Get a Sustainable Future Using Renewable Energy Sources

With worldwide energy consumption increasing by 46% in the past 20 years, renewable energy specialists at Stephens Scown solicitors in Devon and Cornwall are highlighting the importance of renewable energy in the region, as energy needs increase. Despite hitting the headlines in recent months and years, renewables still only accounts for 3.7% of energy consumed in the UK – falling well

National Renewable Energy Laboratory: Solar Has The Most Potential Of Any Renewable Energy Source

A recent study of gargantuan proportions estimated that the technical potential of photovoltaic cells and concentrated solar power (CSP) in the United States, at today’s level of research and with today’s possibilities, is enough to generate about 400,000 TWh of energy annually, significantly more than any other renewable energy source. The study The National Energy Laboratory (NREL) routinely estimates the

Aluminum might be the future’s eco-fuel of choice

If you’re reading ZME Science from home, chances are that you’ve got a can of beer or soda in someplace handy, and you’ll probably throw the can away after you finish your drink, hopefully in a designated recycling bin. What if I told you that the aluminum from your soda can could be used to power your car? Before you yell rubbish,

US electricity demand could be 80% supplied by renewable sources by 2050

According to a recently publicized rapport by the  Department of Energy’s National Renewable Energy Laboratory (NREL), renewable energy sources could account for as much as 80% of the US’s electricity demand by 2050. The rapport signals the various difficulties that need to be overcome to reach this goal, and note that while 80% might be very challenging to reach, a 50% reach

World’s 40th environment day: Denmark and Scotland pave the way

Yesterday marked the 40th Global Environment day, and this year’s theme was ‘Green economy’ – a sector in which, by far, Europe leads the way. When it comes to green energy and reducing the impact industry has on the environment, Denmark and Scotland stand out, by far – just think about Samso, the world’s ‘greenest guinea pig’. Germany is also

“Climate-Change Deniers Have Done Their Job Well”

The big money out there is invested in climate change denial, as major oil companies fight to eliminate climate protection laws or intentionally fund studies which deny climate change; and it’s been a tough few weeks for them. More and more independent studies are highlighting the amount of damage human-caused global warming is caused, and numerous organizations are desperately struggling

Chemical reactions turns CO2 into semiconductor material, and releases energy [!]

In an absolutely remarkable discovery, Professor Yun Hang Hu, along with associates at Michigan Technological University, have discovered a chemical reaction which can turn the alarmingly ever increasing greenhouse gas carbon dioxide into a solid-state semiconductor (Li2CN2), while also releasing energy in the process. You couldn’t ask for something better. CO2 is an extremely pesky compound for researchers, because of its extremely

Eco Energy Lighting Up the Home 2012

When it comes to lighting the home, lumens matter more than wattage. That’s a truth that people are coming to grips with manufactures change the labels on light bulbs to meet new energy-efficiency regulations. Consumers accustomed to equating watts with a certain amount of illumination are beginning to understand that the two are not intrinsically linked. New technologies are driving
