A Nucor steel plant in Missouri will be the first in the U.S. powered by wind energy, while an old steel facility in Colorado is transitioning to solar from Xcel Energy. These renewable-energy sources for recycled steel will make a dent in steel's carbon footprint. The industry contributes as much as 7% of global greenhouse gas emissions.

Power to the people might remain a political pipe dream, but changes taking place in the energy market across Australia are making suburban homeowners the unlikely disruptors in an Uber-style revolution that promises to change how we all live.

Scientists pursuing the holy grail of energy generation are taking giant steps

Solar panels could be made from rows of artificial sunflowers, each less than 1 millimetre wide, which automatically bend towards light

The construction of the International Thermonuclear Experimental Reactor (ITER), the world’s largest nuclear fusion experiment, is now 60 percent complete

Electrical engineers at Duke University have harnessed the power of machine learning to design dielectric (non-metal) metamaterials that absorb and emit specific frequencies of terahertz radiation. The design technique changed what could have been more than 2000 years of calculation into 23 hours, clearing the way for the design of new, sustainable types of thermal energy harvesters and lighting.

The university, which is as big as a city, has slashed its carbon emissions since 2004. That effort is now paying for itself in lower energy costs. Could actual cities do the same?

Millions of solar panels clustered together to form an island could convert carbon dioxide in seawater into methanol, which can fuel airplanes and trucks, according to new research.

Labor productivity doesn't matter as much as emissions productivity. Workers aren't a particularly finite resource.

The absence of the tiniest creature can shape the world in the biggest way. By Robert Krulwich.

Some 18 million barrels of oil transit through every day. The economic impact would be catastrophic. By Scott Ritter.

Nuclear power plants are so big, complicated and expensive to build that more are shutting down than opening up. An Oregon company, NuScale Power, wants to change that trend by building nuclear plants that are the opposite of existing ones: smaller, simpler and cheaper.

"Despite desperate attempts by the oil and gas industry to persuade policymakers that their products have a future in a climate-safe world, a rational look at the data clearly shows otherwise."

The country has not used coal to generate electricity since 17 May, the longest period since the 1880s,

The UK is quickly becoming the epicenter of the offshore wind industry. Point in case: On Monday, the first part of the world’s largest and furthest offshore wind farm came online.

Two UCLA scientists have developed a technology to extract the electrical charge from snow and convert it into power.

California should embrace the idea of building more solar panels than it can consistently use rather than treating oversupply as a problem, research suggests.

A hydrogen refueling station exploded in Norway on Monday and the company operating the station has suspended operation at its other locations following the explosion. Now, Toyota and Hyundai are both halting sales of fuel cell vehicles in the country. Does this spell the end of fuel cell hydrogen vehicles as a “zero-emission” alternative? The …

Blending biofuels and kerosene to create greener jet fuel has shown promising results in test flights, but more work needs to be done to ensure biofuels burn cleanly and can be produced in a large-scale, low-cost way, says Dr Chong Cheng Tung, associate professor at the China-UK Low Carbon College of Shanghai Jiao Tong University in China.

Engineers succeed in automating science experiments at the UK's Halley research station.
