European and German Solar PV Markets

Europe As the largest market in the world, Germany historically has dominated the European market overwhelmingly, with three dominant companies. These were SolarWorld AG, an integrated solar company involved in all steps of the value chain, Q-Cell, a new participant with ambitious plans and Schott Solar (formerly RWE Schott Solar). The solar boom in Spain […]

The History of the US Natural Gas Market 1989-2000

1989 Natural Gas Wellhead Decontrol Act This act completed the process of deregulating wellhead prices. It required the removal of all price controls on wellhead sales with effect from 1 January, 1993, allowing natural gas prices to be freely set in the market. 1991 Mega-Notice of Proposed Rulemaking (Mega-NOPR) FERC requested comments from consumers and […]

The importance of hydro power to electricity generation

Hydro power is much more significant as a generator of electricity. At 15.9% hydro power currently has a larger share than nuclear power which has 13.5%. Hydro power is the most important renewable energy source for the generation of electricity. Hydroelectric resources The theoretical size of worldwide hydropower is about 3,000 GW, four times greater […]

Tidal or Marine Current Energy

Energy can be generated from tidal or marine currents driven by the tides or by oceanic circulations, using completely submerged turbines comprised of rotor blades and a generator. Water turbines work on the same principle as wind turbines, by using the kinetic energy of moving fluid and transferring it into useful rotational and electrical energy. […]

Shale Gas Extraction

Shale gas is extracted using horizontal drilling and hydraulic fracturing or ‘fracking’. None of which are particularly new technologies or shale gas specific. Horizontal drilling During the process wells are drilled vertically to just above the known shale deposit at a depth of 1,500 to 3,000 metres. Then the drill bit is deviated and drilled […]

Reverse Osmosis

Reverse Osmosis (RO) is the most commonly used membrane technology and is the reverse of osmosis. It is mainly used to desalinate low salinity water, especially brackish water and waste water. By definition, RO is the movement of water from an area of low to high water concentration across a semi-permeable permeable membrane by applying […]

Waste Water Treatment

Preliminary treatment/screening Preliminary treatment screens out, grind up, or separate debris is the first step in wastewater treatment. Sticks, rags, large food particles, sand, gravel, toys, etc., are removed at this stage to protect the pumping and other equipment in the treatment plant. Treatment equipment such as bar screens, comminutors (a large version of a […]
