Changes in the sun's energy output may have led to marked natural climate change in Europe over the last 1000 years, according to researchers at Cardiff University.
MIT chemists have devised a way to trap carbon dioxide and transform it into useful organic compounds, using a simple metal complex.
The strangest of things took place in Washington, D.C., on Wednesday: The House of Representatives passed apparently meaningful energy-related legislation with true bipartisan support.
Colorful, see-through solar cells invented at the University of Michigan could one day be used to make stained-glass windows, decorations and even shades that turn the sun's energy into electricity.
Security, predictability, climate change, safety – all of these are cited by the U.S. Department of Defense as motivating factors for its embrace of energy-efficient and renewable technologies. But a new report from the Pew Charitable Trusts puts just as much emphasis on another factor that might come as a surprise: cost.
A new approach to harvesting solar energy, developed by MIT researchers, could improve efficiency by using sunlight to heat a high-temperature material whose infrared radiation would then be collected by a conventional photovoltaic cell. This technique could also make it easier to store the energy for later use, the researchers say.
Solar energy has long been used as a clean alternative to fossil fuels such as coal and oil, but it could only be harnessed during the day when the sun’s rays were strongest. Now researchers led by Tom Meyer at the Energy Frontier Research Center at the University of North Carolina at Chapel Hill have built a system that converts the sun’s energy not into electricity but hydrogen fuel and stores it for later use, allowing us to power our devices long after the sun goes down.
Let’s finish 2013 this way: With a vow to spread the word about the difference between watts and watt-hours, between power and energy.
Volvo seems to want to be on the cutting edge of electric vehicle research, despite the fact it doesn’t have that much in the way of actual green car offerings as of yet. It’s already been involved in a project that puts power lines in roads to consistently charge EVs passing overhead, and now it is tinkering with energy storage built directly into car panels.
Scientists have provided the most comprehensive details yet of the journey energy from the sun takes as it hurtles around Earth's magnetosphere.
When we think about energy, we need to think about water. And when we think about water, we need to think about energy.
Renewable energy holds the promise of reducing carbon dioxide emissions. But there are times when solar and wind farms generate more electricity than is needed by consumers. Storing that surplus energy in batteries for later use seems like an obvious solution, but a new study from Stanford University suggests that might not always be the case.
Efficient is better than not efficient. More efficiency is better than less. In case you’re wondering, there is a light at the end of this tunnel, and I’m pretty sure it looks like the Zero Home.
The link between geothermal power production and earthquakes is one long since established, but new research is providing fresh insight into how Earth responds to this and other sorts of poking around underground that we do.
Harvesting waste heat from power stations and even vehicle exhaust pipes could soon provide a valuable supply of electricity.
In an effort to prove that it can be almost as menacing as China, Iran has apparently hacked a bunch of US energy companies.
Chemical engineering researchers have managed to identify a new mechanism to convert natural gas into energy up to 70 times faster, while effectively capturing the greenhouse gas carbon dioxide (CO2).
A story popped up in my “geothermal power” feed on Sunday with the headline: “DOE set to award 4 renewable energy contracts.”
Nuclear fusion is very close to the point where the amount of energy produced by the system equals or surpasses what's been put in.
There's enough power available in winds to meet the whole of the world's energy demand, says a Carnegie Institution for Science report.
