Submission + - Hydrogen Won't Save Our Economy

anaesthetica writes: Physorg.com is featuring a story asserting that hydrogen is economically infeasible as a replacement for our current energy sources. The premise is that isolating and converting hydrogen into a usable energy source takes up a great deal of energy to begin with, and that subsequently that hydrogen fuel is only useful in about 25% of our economy. Apparently, the increasing scarcity of water is going to make hydrogen too costly and just as politicized as oil. From the article:
[Fuel cell expert Ulf Bossel's] overall energy analysis of a hydrogen economy demonstrates that high energy losses inevitably resulting from the laws of physics mean that a hydrogen economy will never make sense. The advantages of hydrogen praised by journalists (non-toxic, burns to water, abundance of hydrogen in the Universe, etc.) are misleading, because the production of hydrogen depends on the availability of energy and water, both of which are increasingly rare and may become political issues, as much as oil and natural gas are today."

Submission + - Revised UK Windfarm Plans Unveiled

s31523 writes: "With global warming being one of the latest hot topics, the need for "clean" energy is fast approaching. It surprises me that the announcement of UK's largest wind-farm, capable of generating 652MW of electricity, is coming under such heavy criticism by environmental groups. The proposed 181 turbines stand in at a staggering 140 meters tall which is drawing heavy fire from the Royal Society for the Protection of Birds. From the article:
"The Royal Society for the Protection of Birds (RSPB) is concerned about the number of birds which could be killed by flying into turbines and says it would be willing to take the matter to Europe if necessary.""
