Alternative Power Companies Revolutionizing Geothermal Energy

Alternative Power Companies That Show Promise

Ormat Technologies is one of the alternative power companies that are revolutionizing the field of geothermal energy. Though partially owned by American business interests, 60 percent of it is owned by an Israeli holding company called Ormat Industries. It is the leading geothermal alternative power companies primarily in places like California and Nevada where geothermal resources are high. They are set to expand their capacity by two-thirds in the next two years.

Furthermore, California Alternative Power Companies added 500 megawatts of green power in 2008 – a 60% increase. The most difficult challenges lie not in the generation of the power, but rather the power transmission. This aspect will be have to be handled federally, which appears to be happening as the current administration is responsible for a total budget of $18.73 billion for the Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE), 11 times more than the funding from 2008.

This huge influx of money bodes well for First Solar. This alternative power company trades on Nasdaq as FSLR, Energy Conversion Devices, which trades on Nasdaq as ENER, and FPL Group, which trades on NYSE as FPL. FPL group is a utility with big plans for solar and renewable energy. These alternative power companies, though beset by periodic setbacks in the current unstable economy, are poised to continue growing and generating profits.

Alternative Energy Sources Innovation

Monday, May 18th, 2009

Alternative energy sources must be extracted and exploited in order to curb greenhouse gas emissions. These processes of extraction and exploitation, however, must be subject to intense and constant innovation and technological progress to ensure maximum efficiency and efficacy.

For example, geothermal energy is an important resource in volcanically active places such as Iceland and New Zealand. Its importance is increasing in the United States, although it only makes up 3 percent of the nation’s alternative energy sources. The process is that vaporized water is emitted from the earth and cranks a turbine. Water is pumped down an “injection well”, filters through the cracks in the rocks in the hot region, and comes back up the “recovery well” under pressure. It “flashes” into steam when it reaches the surface.

However, Raser Technologies and the United Technologies Corporation revolutionized the technology behind geothermal power with its PureCycle225 power plant at Chena Hot Springs, built originally in 2003. The power plant’s modular design exponentially increases building times. Because of the use of a specific liquid known as R-134a, it can also use cooler water, which increases the number of potential sites and expands the geographic possibilities outside just countries like Iceland or New Zealand that have extremely active geothermal conditions.
