Researchers claim to have discovered vast untapped oceans of geothermal energy they say could replace coal and other so-called fossil fuels as primary U.S. energy sources.

A Colorado landowner ignites his cigarette lighter and holds it close to tap water running from a faucet in his home. A few seconds pass, and the single flame bursts into a ball of fire that sends the man reeling backward.

This shocking scene appears in the 2010 documentary Gasland, produced and directed by filmmaker Josh Fox, which he touts as an exposé on the evils of a particular method of drilling for natural gas called hydraulic fracturing or “fracing,” pronounced “fracking.” Fox claims that nearby drilling contaminated area groundwater, causing the fireball to burst from that Colorado tap.

Political contention over TransCanada’s Keystone XL pipeline is rife with rhetoric and claims of environmental apocalypse, as the paperwork for the proposed 1,700-mile Canada-U.S. pipeline gathers dust on President Obama’s in-tray. If approved, the $7 billion expansion will transport Canadian crude oil from the Athabasca Oil Sands in northeastern Alberta, Canada, southeast through the U.S. Midwest, and then on to the Gulf Coast.

SalazarInterior Secretary Ken Salazar said in an AP interview on September 21 that the Obama administration will continue to support solar power. He made the statement despite the growing scandal over $528 million in loan guarantees to the now-bankrupt California solar power company Solyndra and the practical failure of myriad “alternative energy sources” such as wind and solar power. "I think the future for solar energy is bright. It's not going to be a perfect path where every project proposed is going to be built toward completion." He added that the case of Solyndra demonstrated the challenges facing solar energy industries. Other politicians, such as Governor Brown, stand firmly behind the concept of such government-sponsored enterprises.

Should energy consumers pay extra taxes to fund government-mandated and subsidized renewable energy technologies? "Absolutely yes," says John Bryson, President Obama's nominee for Commerce Secretary. He made the remark at a meeting of the Commonwealth Club of California in 2009 and went on to extol the virtues of hidden rates in California, a state encumbered with some of the nation's highest electricity and unemployment rates.
