A Prudent Action on the Keystone XL Tar Sands Pipeline: Waiting for a Legal Pipeline Route through Nebraska

April 24, 2014 by Danielle Droitsch

Keystone Nebraska Route

The State Department has extended the comment period for the agencies weighing in on the Keystone pipeline. In their announcement, State cited the fact there is no legal route through the state of Nebraska and there won’t likely be one for at least another 6 months to a year or more.[read more]

California to Utilities: Connect Battery-Solar Energy Systems to the Grid

April 22, 2014 by Jeff St. John

The California Public Utilities Commission issued a proposed decision that would exempt most storage-solar projects from extra utility fees and interconnection studies. Instead, it would require utilities to treat them as regular net-metered solar systems, as long as they meet certain requirements.[read more]

How I Went to an Energy Storage Conference and a Data Analytics Session Broke Out

April 22, 2014 by Christine Hertzog

Rodney Dangerfield had a great line about how he went to the fights and a hockey game broke out. It's a witty commentary on the frequency of fist fights between hockey teams. We’re going to witness a similar trend in energy storage conferences. Many will transform into data analytics events.[read more]

Will Utilities Control Behind-the-Meter Solar Batteries?

April 20, 2014 by Jeff St. John

Ken Munson, CEO of Stockton, Calif.-based startup Sunverge Energy, doesn’t want you to think of his company’s product as a “battery in a box,” backing up a roof full of solar panels -- even if that’s one very accurate way to describe what it packages up into a closet-sized, UL-certified form.[read more]

Excitons Observed in Action for the First Time

April 19, 2014 by Energy @ MIT

Solar Tech Advancements

A quasiparticle called an exciton — responsible for the transfer of energy within devices such as solar cells, LEDs, and semiconductor circuits — has been understood theoretically for decades. But exciton movement within materials has never been directly observed.[read more]

Friday Energy Facts: Gulf Coast Crude Oil Inventories Reach Record Level

April 18, 2014 by U.S. EIA: Today in Energy

Gulf Coast Oil Inventories

Crude oil inventories on the U.S. Gulf Coast reached 207.2 million barrels on April 11, a record high. The levels are the result of the continuing strong crude oil production growth, the opening of TransCanada's Marketlink Pipeline, and a drop in crude oil inputs at USGC refineries as a result of seasonal maintenance.[read more]

Floating Nuclear Plants Could Ride Out Tsunamis

April 17, 2014 by Energy @ MIT

Floating Nuclear Plants

When an earthquake and tsunami struck the Fukushima Daiichi nuclear plant complex in 2011, neither the quake nor the inundation caused the ensuing contamination. Rather, it was the aftereffects, the lack of cooling for the reactor cores due to a shutdown of all power, that caused the harm.[read more]

ABCs of LNG

The international reaction to Russia's annexation of Ukraine's Crimean peninsula has put a spotlight on liquefied natural gas (LNG), which was already under debate in the US as a mechanism for exporting increasingly abundant shale gas. Meanwhile, LNG is emerging as a fuel in its own right.[read more]

A Molecular Approach to Solar Energy

April 15, 2014 by Energy @ MIT

Solar Tech Innovation

 

It’s an obvious truism, but one that may soon be outdated: The problem with solar power is that sometimes the sun doesn’t shine.Now a team at MIT and Harvard University has come up with an ingenious workaround, a material that can absorb the sun’s heat and store energy in chemical form.[read more]

Can Nuclear Power and Renewable Energy Learn to Get Along?

April 15, 2014 by Jesse Jenkins

Renewables and Nuclear Cooperation

Nuclear power and variable renewable energy sources like wind and solar power “don’t play well together.” The more I think about this, however, the more I’m convinced that the accepted wisdom that renewables and nuclear mix like oil and water is true only up to a point.[read more]

Shipping Oil by Rail: A Modern-Day Problem of Social Cost

Oil by Rail Risk

While environmental groups and other stakeholders have been working hard to delay, if not completely derail, major pipeline projects like Keystone, oil companies have also been working hard to find alternative ways to get their crude oil to market.[read more]

Lower Prices Pull Down Natural Gas Reserves in 2012

April 13, 2014 by U.S. EIA: Today in Energy

Natural Gas Reserves

Lower natural gas prices drove down U.S. proved reserves in 2012, despite notable gains in the Marcellus and Eagle Ford shale gas plays. The decline stopped a 14-year trend of consecutive increases in natural gas reserves, according to newly published estimates.[read more]

Energy Benefits

The world needs a new energy system that will bolster the environment rather than making it uninhabitable to most living things. Before designing and building such a system, it behooves us to consider what is wrong with what we have and how we can improve on that.[read more]

Solar Energy Farms and Space Needs

In the last few months we have seen both the world's largest solar bridge and the world's largest solar farm open. The bridge was opened in London, a city so famous for its fog that they named a fashion label after it. The farm was built in the middle of the Californian desert.[read more]

Environmental Groups Gear Up to Stop US LNG Exports
