Big leap for fusion: more energy produced than spent igniting fuel

Researchers in the US have overcome a key barrier to making nuclear fusion reactors a reality. In results published in Nature, scientists have shown that they can now produce more energy than put into igniting fuel, at least on an experimental scale. The use of fusion as a source of energy remains a long way off, but the latest development is...

Is it time to move away from silicon-based solar?

CHICAGO—Currently, the world has the capacity to manufacture over 40 Gigawatts of solar panels each year, the vast majority of them silicon-based. And it's easy to see why: our expertise with processing the material has led to a staggering drop in costs, making photovoltaics (PVs) much more cost-competitive than just about anyone had predicted. But...

Carbon dioxide from exhaust can now be used to make new chemicals

Carbon dioxide from exhaust can now be used to make new chemicals Carbon capture is yet to become energy-efficient, but uses of CO₂ are growing. To limit climate change, most governments focus on reducing the amount of carbon dioxide (CO₂) put into the atmosphere. But there are indications that such action won’t be enough—at some point, we...

A way to double the efficiency of solar cells is about to go mainstream

SUNLIGHT is free, but that is no reason to waste it. Yet even the best silicon solar cells—by far the most common sort—convert only a quarter of the light that falls on them. Silicon has the merit of being cheap: manufacturing improvements have brought its price to a point where it is snapping at the heels of fossil fuels. But many scientists would...

Who needs sunlight? In Arizona, solar power never sleeps

GILA BEND, ARIZONA—Every afternoon during the summer, millions of people across the American Southwest come home from work and switch on their air conditioners, straining the power grid in states like Arizona. Traditional solar power—although perfectly suited to the sunny climes of this region—can’t meet this demand since the surge in use peaks...
