Biodiesel is an ester that can be made from substances such as vegetable oils and animal fats. Biodiesel can either be used in its pure state or blended with conventional diesel fuel derived from petroleum. Vegetable oil was used as a diesel fuel as early as 1900, when Rudolf Diesel demonstrated that a diesel engine could run on peanut oil. (more…)

As we here at The Green Blog and often Erenovable, biofuels were a good idea that went astray. They are indeed a renewable energy, “but at the expense of what? Of deforestation, increased food prices, and possible food shortages in the future. Not to mention how undeveloped countries such as Brazil and Argentina are ruining their economies and ecologies because of the monopolization of crops for biofuels. (more…)

According to the German standard VDI 4640 geothermal energy is stored energy as heat beneath the Earth’s solid surface, encompasses the heat stored in rocks, soils and groundwater.
The main energy sources charge of the land are two: the first is the heat recovery of the Earth that can be assessed by the thermal gradient (variation of temperature versus depth), usually increase of 3.3 º C per 100 m depth. (more…)

Do we have the resources? Rudolf Diesel developed the diesel engine which ran on biodiesel vegetable oil in the late 1800s. At the time, he speculated that his discovery seemed insignificant, but later could prove to be as important as mankind’s uncovering of future energy uses for petroleum and coal tar. Given the U.S.’ rapid expansion into biofuels, it would appear his vision was correct due to the drawbacks of biofuels. But widespread adoption of biomass-based fuels is not a foregone conclusion. Two questions haunt its progress. First, will it truly reduce U.S. reliance on fossil fuels? And second, is there enough farmland to accommodate widespread production, without jeopardizing food supplies? (more…)

The increase in the prices of major fuels, like gasoline and diesel fuel products is a major global problems recently. Those prices are increase associated with the global economic crisis. Now, it is the ideal time to move all the focus and effort to alternative fuels for vehicles. There are different types of alternative energy sources for fuel to choose from. But the hard fact is that the areas of alternative fuels have not passed many real qualitative and quantitative surveys and breakthrough research. (more…)
