Envia Systems has created the most energy-dense battery ever, which could bring down the price of electric vehicles and extend their range.

Rick Santorum thinks gas prices caused the recession. No, he really does. A direct quote: "The bubble burst in housing because people couldn't pay their mortgages because they were looking at $4 a gallon gasoline."

A New York court dismissed a case by organic farmers who hoped for protection against Monsanto should the agribusiness giant's genes get into their crops.

ARPA-E's energy innovation summit has kicked into gear.

Alaska's been coasting on its stores of easy-access oil, but a new report from the U.S. Geological Survey shows that the state has a motherlode of shale oil and natural gas. You know what means -- here come the frackers.

The numbers are impressive: as much as 80 trillion cubic feet of frackable natural gas and up to 2 billion barrels of shale oil. To put that in perspective, the natural gas resources are smaller than the Marcellus Shale, which underlays Pennsylvania and New York, and smaller than Texas' Haynesville and Eagle Ford shale formations -- but it's still the fourth biggest parcel in the U.S. The oil shale is the second biggest deposit in the country; only North Dakota's Bakken Formation has more.

If you’ve got “summit Everest” on your bucket list, better get started now. Apa Sherpa (aka "Super Sherpa"), who's summited Mt. Everest 21 times, tells Agence France-Presse (AFP) that the trip up the mountain is getting increasingly dangerous as climate change sets in. As Himalayan glaciers melt, bare rock -- slippery, treacherous, more prone to rockfalls — has replaced snow and ice.

BP's trial for Deepwater Horizon liability has been pushed back one week as the company considers a $14 billion settlement.

Scientist Peter Gleick is taking a leave of absence from the Pacific Institute after the organization's board of directors expressed concern about the methods he used to obtain internal documents from the Heartland Institute.

Meryl Streep won her gamillionth Oscar last night but also marked a personal fashion best by choosing an eco-friendly dress.

In Hawaii, a new wind project will help keep electricity prices steady as the price of oil rises.

It is possible that we are suckers for this North Face campaign because it instructs participants to read Grist every day. But even before we noticed that part, we thought it was one of the best templates for taking green action we've come across.

The Protect Our Winters (POW) pledge has seven ways to fight climate change. And, no, Jon Meacham, none of them involve composting shredded tote bags. They are:

1. Get political
2. Educate yourself
3. Find your biggest lever
4. Be vocal, bug your friends
5. Talk to businesses
6. Change your life and save money
7. Join POW

MSNBC's Morning Joe is a font of conventional wisdom, so I don't feel bad restating this old maxim: Everyone on Morning Joe is a jerk. Here's the evidence, starting at 3:10 or so:

The ever-wise Joe says that Obama's "environmental base" is holding him back because the only type of energy environmentalists like is "getting granola and grinding it up and hoping sparks will come off of it." Oh, and wind and solar matter so little, we might as well just give up on them now. Apparently, according to ex-Newsweek editor Jon Meacham, enviros also think composting shredded tote bags is a way to get energy.

Lucy Lawless, best known for her role as Xena, Warrior Princess, teamed up with Greenpeace to occupy an oil drilling ship.

The panel on Morning Joe posited that environmentalists think the alternative to fossil fuel is granola. (In case this wasn't clear already, everyone on Morning Joe is a jerk.)

A Pew Research Center poll found that 66 percent of people who've heard about Keystone XL want to build the pipeline.

This is not a joke: The sky is falling. Or technically, the height of clouds, the average of which decreased about 1 percent from 2000 to 2010. Researchers at the University of Auckland, who collected the data, attributed the change to a drop in the number of clouds formed at high altitudes.

Man, this video really induces high school flashbacks. A group of seniors at Atlanta's Marist School created it as part of the Green School Alliance's Green Cup Challenge. These fine, upstanding young fellas won the video part of the challenge by adapting Outkast's So Fresh, So Clean to a greener message. The part where they hug trees is the best. Also this part:

A mining company in Idaho wants to keep dumping selenium into local creeks, even after its scientific study turned up these two-headed trout and other deformed fish.

A judge found BP liable for civil damages in the 2010 Deepwater Horizon spill, meaning the company could pay billions in penalties.

Germany is cutting solar subsidies … because they have so much solar power already.

Four out of five wolves that were released near the U.S.-Mexico border as part of a reintroduction program are now dead.
