Well-oiled: The US is targeting oil sales by the Islamic State (also known as ISIS or ISIL). In addition to more air strikes, the US said Wednesday聽it would expand efforts to undermine financing聽for the Islamic State聽鈥� much of which comes from smuggling oil in tanker trucks to sell in Syria, Turkey, and Kurdistan, according to various reports. But disrupting those sales, without permanently damaging the region's oil infrastructure, is聽easier said than done.

Arctic freeze:聽New Russia sanctions strike at the heart of Russian President Vladimir Putin's energy empire, aiming to "shut down" deepwater, shale, and Arctic oil operations. By further limiting Russia's access to Western capital, they threaten the South Stream pipeline, too. Combined with sliding oil prices,聽Moscow will have some soul searching to do as it looks to the future of its energy-based economy.

396: Carbon dioxide levels in Earth's atmosphere increased at the fastest rate in 30 years last year, reaching an聽average global CO2 concentration just shy of 400 parts per million, according to the annual World Meteorological Organization Greenhouse Gas Bulletin released this week. It comes just weeks ahead of international climate talks in New York, and will add聽a heightened sense of urgency to efforts to decarbonize the planet's energy supply.

Thursday, Sept. 18: WASHINGTON and THE INTERNET 鈥撀燯kraine President Petro Poroshenko will address聽US Congress聽and meet with President Obama in Washington.

Thursday, Sept. 18: EDINBURGH, SCOTLAND 鈥� Scots vote in a highly anticipated referendum on independence from the United Kingdom.聽Energy looms large in the debate. Three things to know in advance:

1. If Scotland votes 'yes' to independence, it will take with it North Sea oil reserves that make up most of UK oil production. Those reserves are dwindling, but聽pro-independence forces say there's plenty left to fuel an independent Scotland; Others are聽much more skeptical.

2.聽BP and Shell are the major players in the region, and are against independence, citing the need for investment certainty.

3. Electricity plays a role in the debate, too. Subsidies for Scottish wind and tidal power are spread across the UK, and聽it's unclear how those would be paid for should it secede.

Thursday, Sept. 18 to Friday Sept. 19: JOHANNESBURG, SOUTH AFRICA 鈥� Electra Mining Africa hosts聽the Powering African Industry Conference. Electricity prices are expected to increase by 8 percent annually in South Africa, and many industrial power users (miners, especially) struggle with unstable supply. Many are turning to alternative off-grid energy and energy efficiency best practices for solutions.

A GOP Senate could push energy legislation through the chamber for the first time since 2007, Republican Sen. Rob Portman said at a Monitor-hosted breakfast in Washington Thursday.

EIA's Adam Sieminski: "The United States is expected to provide nine out of every ten barrels of new global oil supplies in 2015."

UNEP: "The Earth's protective ozone layer is well on track to recovery in the next few decades thanks to concerted international action against ozone depleting substances ..."

Stanford University: "Like chefs in a kitchen, state governors, legislators, and public utility commissioners have been testing an array of recipes, to increase the deployment of solar, wind, and other renewables, to cut energy use in homes and businesses, to improve the operation of the grid, to expand financing, and, overall, to improve the efficacy鈥攁nd economics鈥攐f clean energy."
