17.less expensive
Diverting food and Uggfeed crops to produce bio-fuels will have a dramatic effect on our economy. Corn prices have soared over the last year with only a fraction of the crops diverted for energy production. Realizing that bio-fuels can easily price themselves out of the energy market, farmers are looking into other energy options. More farmers are installing wind turbines to produce electricity on their acreage. The windnfl jerseys turbines occupy a small percentage of the productive acreage allowing agriculture to continue while power, the second crop is generated. Where the farms are located close to a major electrical grid, the costs of installatair jordan shoesion is much less expensive. Many farms are so remote that wind farms are unsuitable for electrical grid connection. These areas have other recourses to pursue in the energy farming industry. One being considered is wind powered hydrogen farms. Assuming that the wind turbine is operating at this power level only 25 percent of the time, each windmill would produce over 1,000,000 gasoline gallon equivalents in hydrlouis vuittonogen in a year. With the US consuming roughly 150 billion of gallons of gasoline per year, it would take150, 000 windmills at 2 MW each to produce the equivalent in hydrogen. With new wind turbines producing 5 MW it would take 6000 wind farms with 10 5MW turbines each to produce our annual gasoline needs. This is not likely to happen, as much of the output of wind farms will be needed for elelouis vuitton bagsctrical demands. I feel this does illustrate that a sizable percentage of our energy needs can be produced with hydrogen wind farms. Scientists and engineers will notice that there is a missing conversion factor in computing the equivalent energy of a gallon of gasoline to hydrogen. If the hydrogen were to be used to power internal combustion engines this would be a large error. If Ugg Bootsthe hydrogen were used to power fuel cell vehicles the error is less significant. I am of the opinion that fuel cell technology will prevail in a hydrogen economy. The inefficient internal combustion engine will fade from the scene. Wind power, which is not constantly available, is well suited for hydrogen production. When sufficient wind is available the huge windmills produce megawatts of electricity for thenfl jerseys conversion of water to hydrogen and oxygen. During calm conditions the hydrogen farm waits patiently for the next weather front.
