Hydropower: the unsung hero of renewable energy
Hydropower accounts for more electricity production than solar PV, wind, and geothermal combined. In 2012, hydropower accounted for 16% of the world’s electricity production. However, hydropower gets far less press because it is a mature technology with a much lower annual growth rate than most renewables. While solar PV increased capacity by an average of 60% per year over the past 5 years, new hydropower capacity increased at a much more modest annual rate of 3.3%. ...Despite hydropower’s current dominant position among renewables, growth in consumption of hydroelectricity will likely continue to be modest, because many of the best sites for hydroelectric dams have already been developed. The exception to this is in the Asia Pacific region, where hydroelectric consumption more than doubled over the past decade. The region currently accounts for 35% of global hydroelectric consumption, and that percentage is likely to increase as countries continue to develop hydroelectric power plants. ...
In 2012, at least 78 countries used geothermal directly for energy. Over two-thirds of the geothermal energy for direct use was through geothermal heat pumps. 24 countries operated geothermal plants for electricity production. Total geothermal electricity capacity was 11.7 GW at the end of 2012. Capacity was led by the U.S. with 3.4 GW of capacity, followed by the Philippines at 1.9 GW, Indonesia at 1.3 GW, Mexico at 1.0 GW, and Italy at 0.9 GW. On a per capita basis, Iceland leads the world with 0.7 GW of capacity, which accounted for 30% of the country’s electricity in 2012.
Australia revisits transnational natural gas pipeline
Australia is no stranger to the idea of transnational or even international pipelines when it comes to solving the vexed issue of getting enough gas to its eastern seaboard, home to its biggest cities.Australia currently has two separate gas pipeline networks in the west and east of the country which supply markets of around 1 Bcf/day and 1.6 Bcf/d respectively. A much smaller, also separate, network in central Australia services the Northern Territory capital of Darwin. ...
The latest proposal for a transnational interconnection between Australia’s pipeline networks was initially aired in recent months by former Chief Minister of the Northern Territory Terry Mills, as part of his efforts to secure the future of Rio Tinto’s alumina refinery at Gove. In February, just before being ousted in a party room coup, Mills secured a deal under which Gove would be supplied with gas from Eni’s Blacktip offshore field, heralding a project which would include the construction of a A$500 million pipeline to the plant. ...
That call has now been taken up by Australia’s largest pipeline operator APA Group, manager of 14,120 km of pipeline infrastructure. One of APA’s assets is the 1,600 km Amadeus Basin to Darwin gas pipeline, which was the world’s third-longest when it was completed in 1986 at a cost of just A$380 million. ...
A raft of international oil and gas industry heavyweights have taken a foothold in northern and central Australia’s nascent shale sector over the past few years. Companies including Chevron, ConocoPhillips, Statoil, Total and BG Group have secured farm-in agreements and pledged investments of more than $1.55 billion in Australian shale, according to the US Energy Information Administration. The EIA has estimated that Australia has 437 Tcf of technically recoverable shale gas reserves, ranking the country sixth highest in the world.
2 GW Solar Thermal Power Plant Planned For Kuwait
Kuwait recently started the bidding process for the 70 MW Shagaya Multi Technology Renewable Energy Power Park, which will include a 50 MW CSP plant with 10 hours thermal storage in addition to 10MW PV and 10MW wind. ...There is much more on Kuwait’s renewable energy agenda, however, given that the state-owned Shagaya project is the first of a three-phased master plan proposed by KISR. The second phase will expand the plant’s capacity by 930 MW to bring it up to 1,000 MW, and the third by another 1,000 MW to ultimately reach 2,000 MW by 2030. By then, the complex will generate more than 5,000,000 MWh of power every year, fulfilling the demands of nearly 100,000 households. A 100-square-kilometre (38.6 square-mile) site in Shagaya – a desert area 100km (62 miles) west of Kuwait City, near the borders with Saudi Arabia and Iraq – has been designated for the complex. And while the first phase will be financed by the government, the second and third phases are expected to be offered to investors on a Build-Operate-Transfer basis for 25 years. - See more at: http://social.csptoday.com/emerging-markets/csp-makes-grand-entry-kuwait#sthash.2JgVY40V.dpuf
Look at the whole picture
Reports of the Death of Peak Oil Have Been Greatly Exaggerated
A week or so ago, there was a mini-flurry of blog posts announcing that peak oil was dead. Thanks to shale oil, tar sands, heavy oil, deepwater oil, and all the other kinds of oil that the peakists didn't know about, the world was now practically drowning in the stuff.The whole thing was very strange for several reasons. First, the peak oil community not only knows about all those kinds of nonconventional oil, its forecasts have always included them in minute detail. The question isn't whether they exist, it's when production declines in existing mature fields will outpace the modest amounts of new oil we're getting from nonconventional sources and new drilling technologies. Second, the world isn't drowning in oil. There's no dispute that shale oil has ramped up over the past few years, but it's added only a couple of million barrels a day to worldwide production and it's likely to start declining pretty quickly (within five or ten years or so). It's really not that big a deal on a global scale. Third, peak oil has never been only about the exact date that production of oil hits its highest point. It's been about how long production will plateau; how steep the subsequent decline will be; how expensive it will be to extract nonconventional oil; and how much oil prices will spike up and down as demand bumps up permanently against supply limits.
Hell, a few years ago even the International Energy Agency—which historically had refused to acknowledge production limits even theoretically—finally admitted that peak oil was a reality. When you lose the IEA to the dark side, you really ought to just admit defeat.
‘Nobody understands’ spills at Alberta oil sands operation
Oil spills at a major oil sands operation in Alberta have been ongoing for at least six weeks and have cast doubts on the safety of underground extraction methods, according to documents obtained by the Star and a government scientist who has been on site.Canadian Natural Resources Ltd. has been unable to stop an underground oil blowout that has killed numerous animals and contaminated a lake, forest, and muskeg at its operations in Cold Lake, Alta.
The documents indicate that, since cleanup started in May, some 26,000 barrels of bitumen mixed with surface water have been removed, including more than 4,500 barrels of bitumen.
