The previous comment is not correct. Use of biomass means all cellulose based plant matter, and not corn starch. You canot use starch/sugar/yeast based ethanol to run the economy. As you know about 15% of corn biomass is starch. 85% is cellulose. Bark, leaves, straw, stems, wood chips etc are all biomass suitable for conversion to sugars and to alcohols. The driving force for this is the fact that oil is running out and we must do it or walk. It also means no use of yeast, the cellulose it split into sugars by tethered enzymes that have been tailored for high efficiency as well as high temperature. The sugar is then oxidize to alcohols via similar tethered enzymes.
While <a href="http://www.alternative-energy-news.info/wind-power/">wind power</a> is an excellent alternative form of energy, there are still several problems associated with it. Environmentalists are concerned about endangered bird species that are killed when flying into the large blades. Other studies have shown that the <a href="http://www.alternative-energy-news.info/wind-power/news2006-05-11.php">low-level sound from wind turbines</a> can impact squirrels and their predators, and there has even been on reported incident where a family was made sick and forced to move out of their house due to the noise. As wind farms projects are sprouting up (and being protested) all over the world we are sure to hear more about this debate in the future.

you are so wrong because if you produce hydrogen whit wind and solar wich is free the amount of energy produce by an hydrogen power plant can be far more safer and efficient than a nuclear plant

Sorry, but your claim that wind is as cheap as coal is not correct. First of all, unless you state the wind class of the site, you can't make any claims about the cost of wind power - it depends in very large measure on how strong and how consistent the winds are where the turbines are located. And offshore winds farms are a completely different matter, altogether. Generally, commercial wind electricity will run between 5 and 7 cents per kWhr for onshore generated commercial wind systems. Generally that will be cheaper than natural gas or nuclear, but that all depends upon whether subsidies for those power plants are taken into account. You will get different numbers from different sources. One thing is for certain - it is the cheapest alternative energy source, excepting perhaps hydroelectric.
