Environmentalists lazy to think
"Dump this stupid idea (the hydrogen economy one) and let's just use the solar and wind to generate our electricity directly. THEN let's learn to conserve our energy, and stop living like there's no tomorrow."
It never stops to maaze me how LAZY or uneducated many envinonmentalists are - and I'm always amazed by their ability to ignore facts.
Hydrogen (as in hydrogen economy) is NOT a power source. It is a medium used to transfer energy from where it is generated to where it is needed.
Right now, solar and wind are *unusable* as main power sources. They're unreliable, and we have almost no means of storing electricity on a large scale. People are used to the fact that when it is midnight, they flick a switch and the electricity is there to do whatever they want. Solar and wind CAN'T do that at the moment.
Hydrogen can be generated from fossil fuels (stupid, but doable), or by hydrolysis. You COULD use solar or wind-generated electricity for this (it wouldn't be very cost-efficient, though), because this would give you the much needed ability to store energy, but for this to be worth it *you need that damn hydrogen economy*.
Using electricity, be it solar or nuclear-generated, to produce hydrogen is worth it only if the hydrogen-fueled cars/appliances/whatever become available. HYDROGEN ECONOMY IS ACTUALY A BIG CHANCE FOR SOLAR, WIND AND OTHER "GREEN" TECHNOLOGIES!
