Apple wants you to hug the earth by sending more iMessages

Apple wants you to hug the earth by sending more iMessages

It's Earth Day again, so naturally, companies are going out of their way to show how they care for the environment. As tech companies are also traditionally seen as the worst offenders, they also make the biggest noise come Earth Day. Apple, who has long been waging war on that image, has come up with a rather entertaining video add for this green day. Not only does it not so subtly promote its own efforts to be a green company, it is also subtly advertising iMessage to do so.

Artificial trees generate electricity from small vibrations

Artificial trees generate electricity from small vibrations

Windmills are great, but they do have their downsides: ice is a problem in wintery places, they’re loud if you’re too close, and they’re, you know, enormous. In the future, wind energy generation may look less like giant spinning windmills and more like trees…artificial trees, that is. Researchers with Ohio State University have found that trees experience a type of vibration when shaken that can be used to generate electricity, and this energy generation could be conducted with small-scale artificial trees.

Washington D.C.’s sewage is generating 10MW of electricity

Washington D.C.’s sewage is generating 10MW of electricity

It’s more conventional than drinking water harvested from human waste, but no less interesting: generating electricity from raw sewage. Researchers have given the subject ample attention over the years and especially lately, with the technology promising a future where waste is put to good use and its effect on the environment is lessened. Washington D.C. is one such place testing the technology.

New material mimics photosynthesis, produces hydrogen

New material mimics photosynthesis, produces hydrogen

With the UN Climate Change conference happening this week at Paris, the spotlight is being focused the search for renewable sources of energy, especially ones that will fuel, no pun intended, our every growing number of gadgets and gizmos. As if by happy coincidence, researchers from Florida State University, headed by Assistant Professor of Chemical Engineering Jose L. Mendoza-Cortes almost serendipitously came across a new thin material that could imitate the way a plant uses sunlight to split water into oxygen and hydrogen, the latter of which can be used for fuel.

Gates, Zuckerberg join tech founders in clean energy thrust

Gates, Zuckerberg join tech founders in clean energy thrust

Technology, perhaps more than any other industry, owes much of its existence to the use of energy. So it is only reasonable that it should also be the one spearheading the push for cleaner, greener, and more renewable sources. Of late, Apple has been picking up the pace, and the publicity, of its own green initiative, particularly in China and soon in Singapore. Now it's the turn of the other giants of the tech sector, as Bill Gates, Mark Zuckerberg, and over a dozen other big names to band together under the new Breakthrough Energy Coalition.

World’s first floating wind farm will be near Scotland

World’s first floating wind farm will be near Scotland

While Morocco busies itself with building the largest concentrated solar farm in the world, Scotland is focusing on a similar record of its own — the world’s first ever floating wind farm will be located off the Scottish shores, using ocean winds to generate power for those in the nation. The wind farm will be located 25 kilometer offshore, with production being slated to start in 2017.

Texas wind farms get customers free nighttime power

Texas wind farms get customers free nighttime power

The colder, darker months are upon us, and that means higher electricity bills as lights are on more frequently and heaters are plugged in. Those in some Texas regions won't be feeling the pinch as badly, however, as wind farms have proven successful and the benefits are rolling out to customers. Some utility companies are offering residents free electricity at night, a time when wind turbines are generating the most electricity.

Morocco will be home to world’s largest concentrated solar farm

Morocco will be home to world’s largest concentrated solar farm

Morocco will soon be home to the world’s largest solar farm, according to a new report. The city of Ouarzazate is in the pipeline to get four mega solar plants, all of them linked together into a single complex. This will operate alongside both wind and hydro energy farms, as well, the sum total of which is expected to produce half or more of the nation’s electricity needs by 2020. If all goes as planned, there might be enough electricity left over to export into Europe.

Elon Musk’s SolarCity announces world’s most efficient solar panels

Elon Musk’s SolarCity announces world’s most efficient solar panels

SolarCity, the residential solar panel installer co-founded by Elon Musk, has said that it has developed the world's most efficient rooftop solar panel, achieving an efficiency of just over 22%. The company says that this means the panel is capable of generating more power per square foot and harvesting more energy per year than any other rooftop panel. Limited production is set to start this month, but the plan is to start building 360 watt panels at SolarCity's new 1-gigawatt plant opening in New York next year.

Samsung denies claim its TVs cheat energy efficiency tests

Samsung denies claim its TVs cheat energy efficiency tests

In response the recent report from the UK newspaper The Guardian, Samsung has issued saying it firmly rejects the claim that their TVs use a power-saving mode to cheat energy consumption tests in the lab. As The Guardian reported, EU-funded research group ComplianTV had written an "unpublished" study that found Samsung TVs used a "motion lighting" feature to lower the brightness during lab tests, resulting in lower energy usage levels than what would be found in real-world situations.

Researcher: a penny will buy about 3 hours’ worth of thoughts

Researcher: a penny will buy about 3 hours’ worth of thoughts

The term a penny for your thoughts inspired a researcher to look into what duration of thoughts could actually be purchased with a penny. Quantifying something like this isn't exactly easy, so the researcher decided to base the calculations on energy costs in the United Kingdom, looking at how much energy the human brain uses and how much thinking can be done on a penny's worth of electricity. As it turns out, it doesn't cost much at all to power your epiphanies.

How GM’s giving old batteries a second charge

How GM’s giving old batteries a second charge

General Motors is one of the auto makers working to reuse old electric car batteries, and in its case it is doing so with Chevrolet Volt batteries with one of its IT buildings. Using a handful of old Volt batteries from the model’s first generation, General Motors is powering an administration building in conjunction with wind and solar energy. This is due to the remaining capacities of the batteries after they stop being useful for the Chevy Volt electric cars.
