Renewables Are Now Scotland's Biggest Energy Source

Slashdot -

AmiMoJo writes Government figures revealed that Scotland is now generating more power from "clean" technologies than nuclear, coal and gas. The combination of wind, solar and hydroelectric, along with less-publicized sources such as landfill gas and biomass, produced 10.3TWh in the first half of 2014. Over the same period, Scotland generated 7.8TWh from nuclear, 5.6TWh from coal and 1.4TWh from gas, according to figures supplied by National Grid. Renewable sources tend to fluctuate throughout the year, especially in Scotland where the weather is notoriously volatile, but in six-month chunks the country has consistently increased its renewable output.

‘Talented’ migrants welcome, benefit-seekers not - London Mayor Boris Johnson

RT -

EU immigrants will not be able to claim benefits for their first four years in Britain, according to Prime Minister David Cameron’s new plan on limiting migration to be voiced later on Friday.

Migrants will also be expelled if they don’t find a job within six months.

"We want to create the toughest system in the EU for dealing with abuse of free movement,” an advance copy of Cameron’s speech reads. “We want EU jobseekers to have a job offer before they come here and to stop UK taxpayers having to support them if they don't... EU jobseekers who don't pay in will no longer get anything out. And those who do come will no longer be able to stay if they can't find work.”

Johnson backs the tougher stance on immigration, he told reporters on Friday while on a visit to Singapore.

"I'll have to see what David Cameron says, but I think he's entirely right to want to put in place measures that stop too much of a pull factor, too much of a suction effect that brings people to the country, that might just want to make use of the benefits," Johnson said, as cited by AFP.

That should not however prevent those able to contribute to Britain’s economic growth from coming in, he warns.

"London has done very well from being able to bring in talented people ,so there's a balance to be struck, but I'm confident the prime minister will get it right."

The UK has witnessed a sharp rise in net migration this year, with 260,000 people having arrived by the month of June. That’s 40 percent more than the year before, statistics released on Thursday reveal.

Britain welcomed a ruling by the European Court of Justice earlier this month which said that EU citizens who move to a different member-state, but don’t look for a job, could be refused certain benefits. The decision has been seen as a crackdown on the so-called “welfare tourism” from poorer to richer states.

However, the UK government has continuously been under fire by the European Commission, as well as some EU leaders, for attempts to limit immigration, which they believe would compromise the idea of free movement within the EU.

Venezuelan president resolved to return oil to $100 a barrel

RT -

The continued price plunge is negatively affecting vast social programs run by the owner of the world’s largest proven oil reserves.

“We haven’t managed to do it so far,” Maduro said. “But we will get it our own way and will keep on fighting for the oil price to go up to a fair level of $100 per barrel,” Maduro said at an Air Force military parade on Thursday.

After OPEC’s decision on November 27 not to cut output, oil prices will remain below $80 per barrel, Russian officials and experts warned.

Oil prices have been sliding for the last two months. Last week, the average price of Venezuelan oil plunged below $70 per barrel, its lowest price in four years.

For countries like Venezuela or Iran, the sharp drop oil prices means they will not be able to sustain their government-run social programs.

Last week Maduro reiterated that the prices on the world oil market would get back to the $100 per barrel, as only this price could guarantee stability and a flow of investments into the oil sector.

According to official data, Venezuela is ranked #5 among global oil exporters. The country extracts 3 million barrels of crude oil daily, of which 2.5 million barrels are exported, primarily to the US and China.

Venezuela’s proven oil reserves are estimated at nearly 300 billion barrels. The deposits are concentrated mainly in the so-called Orinoco Belt in the estuary of the Orinoco River. Most of Venezuela’s oil reserves are heavy and ultra-heavy.
