The dispute over TNK-BP erupted last week after the Russian billionaire co-owners of the Anglo-Russian oil joint venture said they planned to sue BP in Moscow and international courts.

Byron King in Energy and Oil looks at the reasons behind the TNK-BP dispute:

The Kremlin has invested heavily in Russia’s image as an energy superpower. During the recent Russian Victory Day celebrations on May 9, many commentators referred to Russia’s energy sector as one of the key elements of Russian power.

Petroleo Brasileiro SA and the UK’s BG Group have made a second major oil find in Brazil’s Santos Basin.

The Guara exploration well struck oil in the BM-S-9 concession area – the same block as September’s Carioca discovery, which could contain as many as 33 billion barrels of oil.

“There are those who will tell you that oil is a cyclical business and a global fungible commodity,” says Christian DeHaemer in Taipan Daily.

The British government gave a huge boost to wind energy stocks this week, opening bidding for offers to build up to 25 gigawatts of offshore wind turbines by 2020 — triple the amount previously planned.

The European Union has set a target date of 2020 for 20% of its energy to come from renewable sources. The British Wind Energy Association said Britain will contribute 15%, meaning up to 40% of the country’s power will come from wind energy by the target date.

“The richest investment opportunities can be found in the fast-emerging alternative energy sector,” says Mike Burnick in The Offshore A-Letter.

Oil exploration experts have predicted that Brazilian oil find – the Tupi deposit and possible offshore fields nearby – may cost up to $240 billion to exploit.

But if the prospects turn out to hold $6 trillion of petroleum, they’ll kick the emerging market into the premier league, making it one of the world’s ten largest oil producers.

“There are those who will tell you that oil is a cyclical business and a global fungible commodity,” says Christian DeHaemer in Taipan Daily.

Solar stock Ersol rose to a new record after German engineering giant Bosch said it paid $157 a share, a premium of more than 60%, for a controlling stake in the company. This from The Guardian:

Shares in leading German solar stocks rose substantially on expectations that other big players, including oil groups, are on the prowl in a market that grew to €6.6bn last year and is forecast to top €18bn by 2020.

Royal Dutch Shell Chief Executive  has weighed in alongside OPEC, claiming that there is no shortage of physical oil supplies, and the crude oil prices should drop.

“As the post-Memorial Day hangover lingers, and $4 per gallon gasoline becomes a national reality, expect more and more daily energy prognostications,” says William Patalon III in Money Morning.

Companies specializing in centralized fossil fuel fired generation need to move towards energy efficiency and diversity of generation, Scottish and Southern Energy, Britain’s second largest energy supplier, said today.

“The days of meeting an unchecked demand for energy through monolithic carbon intensive power stations are coming to an end. Increasingly the emphasis will be on energy efficiency, renewables, cleaned up fossil fuel plant and micro generation,” the company said in a statement accompanying its full-year results, according to Britain’s The Guardian newspaper.

Costs for solar thermal energy will be cheaper than coal as soon as 2020, according to a report from the US Department of Energy, making one solar ETF a great way to profit.

Google, Chevron and Goldman are all betting that this prediction is correct. This from Bloomberg:

Unlike photovoltaic solar panels that convert sunlight to electricity, solar thermal focuses sunrays with mirrors to heat oil in glass pipes to about 700 degrees Fahrenheit (370 degrees Celsius).

China is already the world leader in producing solar cells – now it wants to make a grab other sectors of the alternative energy market.

“Prepare for the onslaught of relatively inexpensive Chinese turbines,” said Steve Sawyer, head of the Global Wind Energy Council, in Wired magazine.

In 2007, China became the world’s number one producer of photo-voltaic cells, holding 35% of the market. Sawyer reckons that China will make enough equipment to generate 10 gigawatts of power annually by 2010 — more than half the capacity that the whole world installed in 2007.
