green future

i have found the best summary of the energy problem, possile renewables and best goverment policies what i have read now:
i am only sceptic about their ideas about green tax, i think they underestimate the negative externalities of fossils.
i find also interesting the oil peak theory, jeremy leggett has a good book about that. the rising oil consumption mainly contributed by china and india and the shrinking oil production will lead the world to change the energy production.
why oil production cannot grove? in the last 20 years - in the ages of cheap oil - there was not enaugh investment and these can't be done in some years.
international energy agency, wich is an office of the united nations publicates a study every year - the world energy outlook. as this paper is prepared by the wisest people in this topic. they have also changed they forcasts and mainly accepted the oil peak theory and they are asking for change in philosphy: energy efficiency should be in focus. and we should invest in renewables but these investments will only yield on longer term - where we face again the same problem: the short term thinking of the most important companies.
so if there is a market failure we need the governments, if possible on the multinational level. kyoto process showed that we can mainly forget multinational level - fast growing countries will not participate, like china and india but that can be understood. kyoto was anyway everything but not useful: mainly none of the countries has done what they have promised.
europien union is a frontier of sustainable growth - but co2 trade and shrink of emission are not a success story. every member state has other policies how to achive the common goals. the big question is which is the best way to make alternative energies market-ready. green taxes are a good way but there are a lot of critics about that also. the subsidies are also questionable - which technics and which companies should recive them? maybe the best way is - and it looks like to work in germany which is pretty well performing in this field - is the warranted prices which are higher than market price. it is very important in this case that these has to be warranted for longer time, have to calculable and have to decline with time (not the case of hungary). maybe it would be a good way to put externalities tax on polluting technologies and finance the alternative energies from this.

conclusion: i have too much free time and need a job
