The U.S. Department of State has received a new application from TransCanada -- the company behind the controversial Keystone XL project -- to ship crude oil via a proposed pipeline running from the Canadian border to existing infrastructure in Nebraska. TransCanada had its initial application rejected by the Obama administration in January. The reapplication to the U.S. State Department on Friday calls to reroute the pipeline around the environmentally sensitive Sand Hills Region of Nebraska -- adding miles onto the project. Despite the new route, some in Nebraska still oppose the plan. The pipeline is causing other problems as lawmakers debate a multi-year surface transportation plan -- the first one since 2005.
If approved, construction on the pipeline could happen in early 2013, with oil flowing as soon as 2014, according to The Canadian Press.
That same day, the Obama administration issued a proposed rule requiring companies drilling for natural gas on federal and tribal lands to disclose chemicals used in hydraulic fracturing. While the rules also set standards for proper construction of wells and wastewater disposal, disclosure of the chemicals used in the "fracking" process would not have to be reported until after work is complete. The regulations, which could go into effect by the end of the year, spurred debate among environmentalists, industry and lawmakers--with some saying the rules didn't go far enough. Others highlighted the "toughest" provisions, which require tests of wells' physical integrity and expand the scope of water protected from drilling -- but pointed out the rules "only apply to a sliver of the nation's natural gas supply."
Gas prices have continued a steady decline the last five weeks, causing the Energy Information Administration (EIA) to revise forecasts for the summer -- predicting motorists will spend $10.7 billion less than previously estimated.
Heartland Institute Pulls Controversial Billboards
The Heartland Institute made headlines again recently for their campaign -- in billboard ads -- that linked terrorists to the belief in manmade global warming. The failed campaign attacking the existence of climate change prompted a firestorm of criticism and recalled another kerfuffle involving the Institute earlier this year. Reactions to the campaign caused the Institute to announce removal of the billboards after being up just 24 hours. Even after they were removed, some donors pulled funding for the Institute, but others weren't so quick to cut their ties with the organization.
A new study focuses blame for warming on another species entirely. It links methane emissions from dinosaurs, the sauropod specifically, to climate change in the past and a warmer Mesozoic era. Like the dinosaurs before them, modern-day methane emitters such as cows and sheep are being studied to determine how the methane they emit could be contributing to warming. Regardless, according to the study, emissions from dinosaurs were far larger than those of our modern-day plant-eating animals, and in fact may have equaled all modern methane emissions -- both natural and manmade.
New data sheds light on the speed of melting glaciers, and how their changes affect sea levels. Greenland's ocean-bound glaciers accelerated by an average of 30 percent from 2000 to 2011 -- not quite as quickly had been estimated in previous worst-case scenarios, but still a cause for concern.
The Rise and Fall of Renewables
While a solar-powered boat was circumnavigating the world, on land the U.S. activated the first solar power project on federal land near Las Vegas. Meanwhile, residential solar leasing is taking off, Motley Fool reported. And in the next five years, the world's solar power generating capacity is predicted to grow more than 200 percent, although public support for green energy initiatives has dropped recently.
Japan may be taking steps toward renewable energy after taking its last nuclear reactor off line last week. The move left the country without nuclear power for the first time since 1970. But MSNBC insisted renewables wouldn't bring immediate relief, as only 10 percent of Japan's power generation currently comes from renewables. Saudi Arabia is exploring whether it can generate a third of its electricity by way of solar power.
In the U.S., the renewable winner may not be necessarily who you think, according to the Washington Post. The EIA now has a map showing a large uptick in renewables between 2001 and 2011. This surge in renewables can largely be attributed to state renewable portfolio standards requiring utilities to obtain a certain percentage of their electricity from renewable sources, federal production tax credits and stimulus grants. The stimulus grants have expired; the tax credit for wind will expire at the end of 2012. The Guardian reports there is an effort underway by conservative think tanks in the U.S. to eliminate all government programs aimed at promoting the use of renewables.
