Energy resources and production in Latin America and the Caribbean

The countries of Latin America and the Caribbean have abundant and varied energy resources, including oil (13% of world reserves), natural gas (5.4%), coal (1.6%), biomass and other renewable resources, as well as great hydropower potential (22%). This apparent abundance of reserves in the region can be misleading, however, because they are highly concentrated in […]

Indonesian Coal Quality and Coal Reserves

Coal quality Indonesian coals are generally low in ash and sulphur, but on account of their low rank, they have a high content of volatile matter and moisture. The run-of-mine coal does not generally require preparation and simple crushing and screening suffices to produce a marketable product. The coal has nil or minimal coking properties, […]

Energy Efficiency in Canada – a historical overview

Government investment in energy efficiency and low carbon technologies has been surpassed by investments in wind, solar, other renewables and biofuels, with only 6% of investment being directed towards this sector between 2005 and 2010. A CAD 1.5 billion trust fund is available for clean air and climate change initiatives including energy efficient projects that […]

Issues facing wind energy

Storage To resolve intermittency issues, several storage technologies are being investigated: mechanical, chemical and electromagnet. So far, large scale, low cost storage technologies with a fast response rate are not commercially available. Capacity credit Wind cannot be turned on at will, so it is not dispatchable. The relatively low capacity credit of wind power, which […]

Orimulsion

Although natural bitumen and extra-heavy oil occur worldwide, a single extraordinary deposit in each category is dominant. These are sometimes called the Fourth Fossil Fuel. The 1.2 trillion barrels of extra-heavy crude oil deposit of the Orinoco Oil Belt, a part of the Eastern Venezuela basin, represent nearly 90% of the known extra-heavy oil in […]

Statoil Markets

Natural gas produced is exported via pipelines through the Gassled system from Norway to European markets (which Statoil has a 32.1% ownership in). The majority of gas produced, around 80% to 90%, is sold through long-term contracts to large European gas utility companies and suppliers. The remaining gas is traded on the spot market and […]

Compressed Air Energy Storage (CAES)

A CAES system is comprised of a compressor unit with a motor, gas turbine and storage facility. Usually at night the motor compresses and stores air which is cooled by a cooler unit. Then, during peak demand hours the compressed air is supplied to the combustion chamber in the turbines to burn the fuel. Combustive […]
