6:58 PM | The Slow Decline Of Biofuels - Corn Stover Inclusion Won't Help
Biofuels - ethanol - were trumpeted as being a renewable alternative to fossil fuels for decades. Finally, in 2005, it got the mandates and subsidies environmentalists insisted were necessary to make inroads against a mature industry like petroleum. Immediately, what scientists knew became evident - they were more resource intensive to produce, were no better for emissions, and subsidies insured there was no reason to get more efficient. Worse, the gold rush of government money drove up corn […]

12:38 AM | So There’s This Kid Making Solar “Death Rays” And They’re Pretty Sweet (Video)
Eric Jacqmain is just a creative guy who wanted a death ray. So, he decided to cover a satellite dish with 5,800 tiny mirrors. This is from his video description: “When properly aligned, it can generate a spot the size of a dime with an intensity of 5000 times normal daylight. This intensity of light […]

9:00 PM | Federal Appeals Court Upholds EPA Mercury Rule
A federal appeals court upheld the U.S. Environmental Protection Agency’s Mercury and Air Toxics Standards (MATS) requiring power plants install technology to cut emissions of mercury and other air pollutants. MATS was challenged by industry and several states that argued the EPA should have considered costs when determining whether it was “appropriate and necessary” to go forward with the standards. The…

4:08 PM | Tesla On The Horizon: Wireless Power Now Works Over 15 Feet
Researchers have reported a big improvement in the distance of wireless power.   Their "Dipole Coil Resonant System (DCRS) boosts the extended range of inductive power transfer up to 5 meters between transmitter and receiver coils.  It's not quite the rumors about Nikola Tesla but if you think that's not a lot, ponder that Bluetooth is only slightly greater after 15 years in progress.read more

2:12 PM | Energy Connections: Shocking climate change vs. shocking solar power
One of the most important realizations of climate change research is exemplified in this graphic from Weather Uderground: The point is this. The PETM (Paleocene-Eocene thermal maximum, millions of years ago) was a period of high levels of CO2 in the atmosphere which caused significant warming. It is an example of both relatively rapid and…

3:28 PM | Mitigate Electric Vehicle Charge Rage With Improved Batteries
There's a disturbing, though funny to outsiders, trend sweeping green conscious corporations on the coasts of the United States - flurries of emails between indignant employees talking about how long their cars have been plugged in. Though subsidies and public relations campaigns for electric cars are everywhere to be found, improvements in batteries have been absent for decades. Unless we want acid rain to come roaring back, there needs to be an improvement. Electric car companies are not […]

7:07 AM | Would addressing climate change improve energy security?
By Jessica Jewell, Research Scholar, IIASA Energy Program How would action to mitigate climate change affect energy security for countries around the world? In two recent studies that I worked on with colleagues in IIASA’s Energy Program and three other European research centers, we explored this question under a range of different policy scenarios. We found … Continue reading →

3:52 PM | Genetically Modified Tobacco Plants As Biofuel
Tobacco is a high-density crop that is mowed several times throughout its cycle and that can be a good thing, because it can produce as much as 160 tons of fresh biomass per hectare. Biomass that is suitable for producing bioethanol.  Smoking cigarettes is bad but renewable energy is good, tobacco just needs some help from science.read more

2:53 PM | Climate change solution? UN touts ambitious (but cheap) investment in renewable energy
The world is warming rapidly due to greenhouse gas emissions, threatening everything from our food supply to our ecosystems, but the solution may be surprisingly cheap, according to the third and final report from the Intergovernmental Panel on Climate Change (IPCC). The report recommends a rapid and aggressive switch from fossil fuel-based energy to renewables.

11:56 AM | Navy Process to Make Fuel from Seawater
Researchers at the US Naval Research Laboratory (NRL) announced that they have successfully tested a process to convert seawater into jet fuel. They can extract CO2 both dissolved and bound from the water as a source of carbon, and can extract H2 through electrolysis. They then convert the CO2 and hydrogen into long chain hydrocarbons: [...]
