Geothermal drilling technology is adapted from the oil industry. Most of the geothermal wells are drilled with a rotary-type drilling rig. Because of the hard, abrasive, and high-temperature volcanic rocks of geothermal systems, the drilling bits require hard abrasive resistant teeth such as diamond or tungsten carbide. Hence, geothermal drilling is an expensive activity in geothermal development. Most geothermal wells are drilled 1 to 2 km deep to intersect faults and fractures so as to increase the success rate of production from permeable zones. (more…)
Geothermal wells need to undergo a test program before they are used. This is so that the baseline conditions of both the wells and ...

Under both former President Bush and new President Obama, the U.S. government has vowed to reduce reliance on imported oil. The nation is encouraging development of a transportation fleet that uses biofuels, fuel cell vehicles and hybrid electric technologies.
Us Government Program To Reduce Reliance On Imported Oil
To that end, the federal government, in late 2008, put in place new incentives – and extended others – designed to create a strong up-tick in sales of unconventional vehicles. As a result, the U.S. Energy Information Administration anticipates that hybrid cars will grow from 2% of new light-duty vehicles sold in 2007 to 38% by 2030. (more…)

We had expressed our disagreement with Biofuels and tell them also that the European Union also wants to distance themselves from them. Now the FAO (United Nations Food and Agriculture) has been enacted against biofuels in its annual report. The main problem with biofuels is that the growing of them, occupy spaces before for food, and to create more spaces and woodlands are only by cutting down forests. (more…)

You’re paying a lot more for energy of all kinds these days—oil, gas, and electricity cost double (and in some cases, nearly triple) what they ran you just a few short years ago. The higher cost of energy is also reflected in the price of everything else you buy; energy-related price hikes have been shooting out of sight recently. (more…)

It is a reasonable and sensible action to tighten our belts and cut spending as living cost are climbing nowadays. We have to make small sacrifices if we want to survive the economic crisis which we don’t know when it will be ended.
For some folks cutting down expenses are difficult, but actually it is not going to be hard as we thought. Starting with small changes like re-arranging your home power consumption to be energy efficient would be a good start. If you manage to save some bill on household power consumption a bit often, the accumulation effect over a length period of time will be enormous. At the end it can help you in better shaping your financial situation. (more…)
