The water levels of most of the world’s rivers fluctuate with seasonal rains, melting snows, or droughts, and in the arid zones there are flash floods. It makes sense to capture and store the abundant waters and later release it during the low flow periods or use it for power. So dams have been built for the purposes of irrigation, municipal water supply, and hydroelectricity generation. Flood control and transportation benefits are also important. Cities are growing all over the developing world, and they require water supplies and reservoirs. Since the beginning of the 20th century, hydropower energy has steadily increased and it now supplies 19% of worldwide electricity. (more…)

I just read a very good news via Reuters. And is that the EU has decided to distance themselves from biofuels usage.
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…)

Estimation of the future technical potential of biomass as an energy source is dependent on assumptions with respect to land availability and productivity as well as conversion technologies. With the emergence of energy crops as the major source of biomass fuel, land use conflicts, especially in relation to food production, may arise. However, with efficient agricultural practices, plantations and crops could supply a large proportion of energy needs, with residues playing a smaller role without compromising food production or further intensifying agricultural practices.

One of the main benefits from future use of biofuels would be the reduction of greenhouse gases compared to the use of fossil fuels. Carbon dioxide, a greenhouse gas that contributes to global warming, is released into the air from combustion. Twenty-four percent of worldwide energy-related carbon emissions in 1997 were from the United States. Carbon and due to rising energy consumption, are expected to increase 1.3 percent per year through 2015. (more…)

Advances in biomass feedstock production are extremely important. These advances have the potential for reducing the final cost of biofuels, power, and products. In addition, advances will allow the production of plants, trees, and residues with characteristics increasingly well suited for feedstocks. For example, genetically engineered plants feedstocks may allow higher yields of usable biomass per acre for fuel and other uses. New methods in erosion control, fertilization, and pre-processing can result in (more…)
