Gleaning electricity from radio signals isn’t super-efficient (or a new concept), but it’s possible technically. Two companies from Japan have recently come up with new devices that can do just that: one is harvesting energy from cell phone signals, the other uses a rectifying antenna (Rectenna) to produce energy. → Read More
Remote electricity meters are interesting things. They essentially change the way you think about the juice flowing into your home by connecting to the potentially aged box in your basement and sensing the total energy usage in your home over time. The resulting stats are often quite enlightening and may help you make wiser energy-use decisions. → Read More
The news has become muted regarding <a href="fuel cells and their future role in energy supply in recent years, but it seems we’re getting there step by step: Panasonic today said that it has developed a new type of home-use fuel cell [press release in English], which is more efficient and cheaper than its existing solutions. → Read More
Fujitsu today announced the development of a single device that’s capable of generating electricity from either heat or light. Previously, two devices had to be combined to generate electricity from these sources (through energy harvesting, energy can be derived from external sources like light, heat, vibrations, wind energy etc.). → Read More
For all the talk about solar, the US market for solar power still has a long way to go before it makes a real dent in the country’s overall power capacity.
On Monday morning, Bloomberg New Energy Finance, a major aggregator of green industry data released a few key projections: the US solar market is on track to grow 30x to 44 gigawatts by 2020 and could make up 4.3% of America’s total power capacity.
Of course, that path to 4.3% is not cheap. In order to get there, the US market will need to attract $100 billion in investment dollars. → Read More
Sanyo in Japan today announced [JP] what it says is the world’s first solar-cell-equipped public bus, the Solarve (which stands for Solar Vehicle). The bus was unveiled to commemorate the 100th anniversary of a Japanese transportation and logistics company called Ryobi [JP]. The Solarve is essentially a city bus with solar cells on top that generate power for its interior LED lights. → Read More
Quick, name one of the best things you can do to save energy at home. If you said “turning off the lights,” you’d be wrong. But you are not alone, most Americans say the same thing. A new survey shows most people have misconceptions about what works best to save energy.
Keeping lights off isn’t a bad idea in itself, but it has significantly less impact than swapping out the bulbs for more energy-efficient ones, says Shahzeen Attari, who published a paper on the survey. → Read More
Alternative energy is a growing market, and though many states offer tax credits, rebates, and other incentives to promote clean energy, it can still prove to be an expensive proposition.
It generally also requires plugging your energy source into the grid so you’re not left in the dark when the wind calms or the sun lingers behind clouds.
Here is a roundup of solutions that can help power a home. → Read More
Most green technologies gather energy above ground, but like Jules Verne, we want to take you on A Journey to the Center of the Earth. Alright, not even close to the center, but deep down nonetheless, where naturally occurring hot water can be turned into clean energy above ground.
It is estimated that the amount of heat within 30,000 feet below the earth’s surface holds potentially 50,000 times more energy than all global oil and natural gas resources combined. According to the Geothermal Energy Association, up to 6,400 megawatts of new capacity could be created from the geothermal projects under development in the U.S. But getting to that energy is proving to be a challenge. → Read More
The U.S. Department of Energy announced today that it will award up to $122 million to create a Fuels form Sunlight Energy Innovation Hub led by the California Institute of Technology. The Hub’s goal is to develop ways to convert solar energy into chemical fuels and scale the technology for commercial use.
The project is in part inspired by the way plants produce energy, and will use artificial photosynthesis to turn sunlight, water and carbon dioxide into clean fuel. Researchers will be charged with finding ways to use technologies like light absorbers, catalysts, molecular linkers and separation membranes to transform sunlight into fuel, and the DOE aims to quickly turn the research into a viable product in the form of fuel that can go directly into cars without any additional processing. → Read More

Is there a green movement in China? Maybe there ought to be, considering the numbers that have just come out. China is now the planet’s number one consumer of energy, overtaking the U.S. in the process. But at the same time, the U.S. has improved its energy efficient more so than China, meaning that the U.S. can get the same amount of work done while consuming less, say, coal or oil. → Read More
A solar-powered airplane, named the Solar Impulse, means to prove, once and for all, that harnessing the energy of the Sun is a good and practical idea. I mean, why would we try to capture some of the energy put out by a completely free nuclear reactor hanging in the sky? The plane took off from Switzerland a little bit ago, and will try to fly for 24 hours without stopping. Here’s hoping it’s a great success. → Read More
Clean technology remains one of the hottest areas of venture funding. In the second quarter, cleantech venture investments worldwide totaled $2.02 billion across 140 companies, according to market research firm Cleantech Group and Deloitte.
