White House Says Obama Would Veto Keystone Pipeline Bill

By Coral Davenport

President Obama will veto a bill authorizing the construction of the Keystone XL oil pipeline if it passes Congress, his spokesman said on Tuesday, setting up a clash between the White House and the new Republican-led Congress.

“I would not anticipate that the president would sign this legislation,” Josh Earnest, the White House press secretary, said during a briefing. He later clarified that the president would indeed veto the bill.

The Keystone bill was the first introduced in the Senate in the new Congress, and Senator Mitch McConnell of Kentucky, the new majority leader, has vowed to make it the first measure sent to the president’s desk. The House is expected to pass the bill on Friday, while the Senate is expected to take up the measure next week.

It was widely expected that Mr. Obama would veto the measure. As written, the bill would remove the requirement that the president authorize the construction of the oil pipeline to Canada, and instead give that authority to Congress. Mr. Obama issued a veto threat to a similar bill passed by the House in 2013.

Fossil fuels should be phased out by 2100 says IPCC

The unrestricted use of fossil fuels should be phased out by 2100 if the world is to avoid dangerous climate change, a UN-backed expert panel says. The Intergovernmental Panel on Climate Change says in a stark report that most of the world’s electricity can – and must – be produced from low-carbon sources by 2050. If not, the world faces “severe, pervasive and irreversible” damage. The UN said inaction would cost “much more” than taking the necessary action.

Australia has proved Solar power can replace fossil fuels

World first: Australian solar plant has generated “supercritical” steam that rivals fossil fuels’

A CSIRO test plant in Australia has broken a world record and proved solar power could efficiently replace fossil fuels.

A solar thermal test plant in Newcastle, Australia, has generated “supercritical” steam at a pressure of 23.5 MPa (3400 psi) and 570°C (1,058°F).

CSIRO is claiming it as a world record, and it’s a HUGE step for solar thermal energy.

“It’s like breaking the sound barrier; this step change proves solar has the potential to compete with the peak performance capabilities of fossil fuel sources,” Dr Alex Wonhas, CSIRO’s Energy Director, told Colin Jeffrey for Gizmag.

The Energy Centre uses a field of more than 600 mirrors (known as heliostats) which are all directed at two towers housing solar receivers and turbines, Gizmag reports.

This supercritical steam is used to drive the world’s most advanced power plant turbines, but previously it’s only been possible to produce it by burning fossil fuels such as coal or gas.

“Instead of relying on burning fossil fuels to produce supercritical steam, this breakthrough demonstrates that the power plants of the future could instead be using the free, zero emission energy of the sun to achieve the same result,” Dr Wonhas explained.
