Should you install solar panels on your roof? Ask Google

In 2015, Google launched Project Sunroof, a map that shows which houses have enough sun exposure for solar panels to be a viable energy source. However, the original map was very limited, covering only the San Francisco Bay Area, Fresno, California and Boston. Now, Google has greatly expanded the project to cover all 50 U.S.

GreenWish to Invest $280 Million in Nigeria Solar Plants

GreenWish Partners, a Paris-based independent power producer, will invest $280 million to build solar-power plants in Nigeria that are expected to start producing electricity in the first quarter of next year. A plant in the southeastern state of Enugu will produce 100 megawatts, while the company will build two others of 50 megawatts each in

Unstoppable: Why The Next Decade Belongs To Renewable Energy

The greatest challenge for mankind in the 21st century is powering the planet, while at the same time drastically reducing carbon emissions and continuing to lower the cost of energy. One year ago, GE published a Ecomagination report that examined the incredible acceleration of renewable energy development across the globe. We called upon businesses, investors and governments

Clean energy is now as big as pharmaceutical manufacturing in the US

Across the world, myriad efforts are underway to make energy systems cleaner, smarter, and more efficient. But it’s hard to get a sense of the total size of those efforts, as they are spread across so many different industries and regions. One organization that has given this quite a bit of thought is Advanced Energy

Molecular ‘leaf’ that collects and stores solar power without solar panels

An international team of scientists led by Liang-shi Li at Indiana University has achieved a new milestone in the quest to recycle carbon dioxide in the Earth’s atmosphere into carbon-neutral fuels and others materials. The chemists have engineered a molecule that uses light or electricity to convert the greenhouse gas carbon dioxide into carbon monoxide

Caltech discovery: Water the Fuel of the Future?

Researchers at Caltech and Lawrence Berkeley National Laboratory (Berkeley Lab) have—in just two years—nearly doubled the number of materials known to have potential for use in solar fuels. They did so by developing a process that promises to speed the discovery of commercially viable solar fuels that could replace coal, oil, and other fossil fuels.

The world’s first heat-driven transistor

The results have now been published in Nature Communications. “We are the first in the world to present a logic circuit, in this case a transistor, that is controlled by a heat signal instead of an electrical signal,” states Professor Xavier Crispin of the Laboratory of Organic Electronics, Linköping University. Possibilities for new applications The

U.S. renewables a job engine, trade groups say

A consortium of U.S. clean-energy groups said it was growth in the industries tied to renewable energy that were the ones creating more jobs. Business groups supporting the renewable energy sector in the United States said data compiled from federal reports find the low-carbon industry supported more than 3 million jobs last year.

Rutgers Develops Eco-Friendly Concrete

In the future, wide-ranging composite materials are expected to be stronger, lighter, cheaper and greener for our planet, thanks to an invention by Rutgers’ Richard E. Riman. Nine years ago, Riman, a distinguished professor in the Department of Materials Science and Engineering in the School of Engineering, invented an energy-efficient technology that harnesses largely low-temperature,

New, long-lasting flow battery could run for more than a decade with minimum upkeep

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new flow battery that stores energy in organic molecules dissolved in neutral pH water. This new chemistry allows for a non-toxic, non-corrosive battery with an exceptionally long lifetime and offers the potential to significantly decrease the costs of

Bacteria fed synthetic iron-containing molecules turn into electrical generators

The bacterial world is rife with unusual talents, among them a knack for producing electricity. In the wild, 'electrogenic' bacteria generate current as part of their metabolism, and now researchers have found a way to confer that ability upon non-electrogenic bacteria. This technique could have applications for sustainable electricity generation and wastewater treatment. Read more

Thin, flexible, light-absorbent material could be used in energy and stealth applications

Transparent window coatings that keep buildings and cars cool on sunny days. Devices that could more than triple solar cell efficiencies. Thin, lightweight shields that block thermal detection. These are potential applications for a thin, flexible, light-absorbing material developed by engineers at the University of California San Diego. The material, called a near-perfect broadband absorber,

Toward all-solid lithium batteries

Most batteries are composed of two solid, electrochemically active layers called electrodes, separated by a polymer membrane infused with a liquid or gel electrolyte. But recent research has explored the possibility of all-solid-state batteries, in which the liquid (and potentially flammable) electrolyte would be replaced by a solid electrolyte, which could enhance the batteries’ energy

Iowa State University scientists design electricity generator that mimics trees

Money doesn’t grow on trees, but electricity might someday. Iowa State University scientists have built a device that mimics the branches and leaves of a cottonwood tree and generates electricity when its artificial leaves sway in the wind. Michael McCloskey, an associate professor of genetics, development and cell biology who led the design of the

Cheap Renewable Energy from Tech Titans Blazes Trail for Little Guys

Google's recent announcement about its “100% renewable” goal follows similar claims by Apple, Facebook, Microsoft, and other tech giants about reducing their reliance on fossil fuel for their power-hungry supply chains. Their push towards renewable energy for their energy needs largely reflects how prices are plummeting for solar and wind power. The good news is

Renewables Now Cheapest, But How To Enable Faster Renewable Energy Growth?

Renewable energy is now the cheapest option, on average, for new electricity capacity around the world — in developed countries like the US as well as developing countries like India, China, Nigeria, and Mexico. As I noted the other day, we need to keep channeling this message to the broader public, and especially decision-makers, but there are

Why more and more countries are taking an interest in geothermal energy

At 2:46 p.m. local time on Friday, March 11, 2011, Japan was rocked by the largest earthquake ever to strike its shores. The 9.1 magnitude quake triggered a devastating tsunami that killed more than 15,000 people. It also took out the back-up emergency generators that cooled the reactors at the Fukushima Daiichi nuclear power plant
