Report: Sun's energy influences 1,000 years of natural climate variability in North Atlantic

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.

Report: New catalyst could lead to cleaner energy

MIT chemists have devised a way to trap carbon dioxide and transform it into useful organic compounds, using a simple metal complex.

Energy efficiency bill wins bi-partisan support

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.

Transparent, color solar cells fuse energy, beauty

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.

Solar energy helps the military save

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.

How to tap the sun’s energy through heat as well as light

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.

Harnessing the sun’s energy during day for use at night

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.

What is the difference between power and energy?

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.

Future electric cars could store energy in panels

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.

NASA spacecraft track energy through space

Scientists have provided the most comprehensive details yet of the journey energy from the sun takes as it hurtles around Earth's magnetosphere.

Report links energy, water savings

When we think about energy, we need to think about water. And when we think about water, we need to think about energy.

How much energy is required to store wind and solar power on the grid?

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.

And the most energy efficient house In America is...

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.

Analyzing the earthquake-energy connection

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.

Ionic liquid breakthrough in thermal electrical energy

Harvesting waste heat from power stations and even vehicle exhaust pipes could soon provide a valuable supply of electricity.

Iran hacks US utilities

In an effort to prove that it can be almost as menacing as China, Iran has apparently hacked a bunch of US energy companies. 

A faster way of converting natural gas to energy

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).

Geothermal to inch forward in 2013

A story popped up in my “geothermal power” feed on Sunday with the headline: “DOE set to award 4 renewable energy contracts.”

Nuclear fusion nears efficiency break-even

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.

Wind could feed world's total energy demand

There's enough power available in winds to meet the whole of the world's energy demand, says a Carnegie Institution for Science report.
