The long-term petroleum price outlook - When will it escalate?

For the last few years, the Saudi kingdom’s insistence on pumping oil at high capacity has dramatically depressed oil prices. The result has undermined Saudi’s major oil rivals in OPEC – like Iran and Venezuela.

It has also hit Russia, hard.

Rating agency Standard & Poor forecasts that Russia’s budget deficit is set to swell to 4.4 per cent of GDP this year. Russia’s own finance ministry concedes that if expenditures continue at this rate, within sixteen months – by around the end of next year – its oil reserve funds will be exhausted.

Meanwhile, over the last year real incomes have dropped by 9.8 per cent, and food prices have spiked by 17 per cent, heightening the risk of civil unrest.

System failureh

Rumbling along beneath the surface of such financial woes are deeper systemic issues.

A report from the Swedish Defence Research Agency notes that “prolonged dry periods in southern Russia are having the effect of reducing the level of food production”.

Most of Russia’s wheat imports come from Kazakhstan, “where climate change is expected to exacerbate droughts. These impacts would make farming harder and food more expensive,” observe Dr. Marina Sharmina and Dr. Christopher Jones of the Tyndall Centre for Climate Change Research.

Russia’s looming energy crisis is the other elephant in the room. In 2013, HSBC forecasted that Russia would hit peak oil between 2018 and 2019, experiencing a brief plateau before declining by 30 per cent from 2020 to 2025.

That year, Fitch Ratings came to pretty much the same conclusion. And last year, Leonid Fedun, vice-president of Russia’s second largest oil producer, Lukoil, predicted that the production could peak earlier due to falling oil prices and US-EU sanctions.

Faced with overlapping economic, food and energy crises, Russia is well and truly on the brink. More

Furthermore, According to a recent report from the IMF, Saudi Arabia’s public debt is estimated to rise from below 2 percent of its GDP in 2014 up to 33 percent by the end of 2020. The report also shows that in the past three years, Saudi Arabia’s budget surplus was turned into a deficit reaching 21.6 percent of GDP in 2015. More

Solar Resource Fundamentals

We have, on this planet, vast renewable energy potential: First and foremost, the solar energy resource is very large (Perez et al., 2009a). Figure 1 compares the current annual energy consumption of the world to (1) the known planetary reserves of the finite fossil and nuclear resources, and (2) to the yearly potential of the renewable alternatives. The volume of each sphere represents the total amount of energy recoverable from the finite reserves and the annual potential of renewable sources.

While finite fossil and nuclear resources are very large, particularly coal, they are not infinite and would last at most a few generations. More

The Great Transition, Part I: From Fossil Fuels to Renewable Energy

The great energy transition from fossil fuels to renewable sources of energy is under way. As fossil fuel prices rise, as oil insecurity deepens, and as concerns about pollution and climate instability cast a shadow over the future of coal, a new world energy economy is emerging.

The old energy economy, fueled by oil, coal, and natural gas, is being replaced with an economy powered by wind, solar, and geothermal energy. The Earth’s renewable energy resources are vast and available to be tapped through visionary initiatives. Our civilization needs to embrace renewable energy on a scale and at a pace we’ve never seen before.

We inherited our current fossil fuel based world energy economy from another era. The 19th century was the century of coal, and oil took the lead during the 20th century. Today, global emissions of carbon dioxide (CO2)—the principal climate-altering greenhouse gas—come largely from burning coal, oil, and natural gas. Coal, mainly used for electricity generation, accounts for 44 percent of global fossil-fuel CO2 emissions. Oil, used primarily for transportation, accounts for 36 percent. Natural gas, used for electricity and heating, accounts for the remaining 20 percent. It is time to design a carbon- and pollution-free energy economy for the 21st century.

Some trends are already moving in the right direction. The burning of coal, for example, is declining in many countries. In the United States, the number two coal consumer after China, coal use dropped 14 percent from 2007 to 2011 as dozens of coal plants were closed. This trend is expected to continue, due in part to widespread opposition to coal now being organized by the Sierra Club’s Beyond Coal campaign.

Oil is used to produce just 5 percent of the world’s electricity generation and is becoming ever more costly. Because oil is used mainly for transport, we can phase it out by electrifying the transport system. Plug-in hybrid and all-electric cars can run largely on clean electricity. Wind-generated electricity to operate cars could cost the equivalent of 80-cent-per gallon gasoline.

As oil reserves are being depleted, the world has been turning its attention to plant-based energy sources. Their potential use is limited, though, because plants typically convert less than 1 percent of solar energy into biomass.

Crops can be used to produce automotive fuels, such as ethanol and biodiesel. Investments in U.S. corn-based ethanol distilleries became hugely profitable when oil prices jumped above $60 a barrel following Hurricane Katrina in 2005. The investment frenzy that followed was also fueled by government mandates and subsidies. In 2011, the world produced 23 billion gallons of fuel ethanol and nearly 6 billion gallons of biodiesel.

But the more research that’s done on liquid biofuels, the less attractive they become. Every acre planted in corn for ethanol means pressure for another acre to be cleared elsewhere for crop production. Clearing land in the tropics for biofuel crops can increase greenhouse gas emissions instead of reducing them. Energy crops cannot compete with land-efficient wind power. More

Is The world About To Be Running On Empty?

23 May, 2008 - In France, fishermen are blockading oil refineries. In Britain, lorry drivers are planning a day of action. In the US, the car maker Ford is to cut production of gas-guzzling sports utility vehicles and airlines are jacking up ticket prices.


Global concerns about fuel prices are reaching fever pitch and the world's leading energy monitor has issued a disturbing downward revision of the oil industry's ability to keep pace with soaring demand.

Yesterday's warning from the International Energy Agency sent the price of a barrel of oil to a new record for the 13th day in a row. The latest high – $135 for a barrel of light sweet crude – was reached in New York barely five months after the price hit $100. More >>>
