worldwide economic problems and the true scale of the carbon reductions required,a survey pub-

lished today has suggested.

Figures presented at the UN climate talks in Poznan,Poland,show that climate experts have

less faitll in alternative energy than they did 12 months ago.

The survey shows less support for wind energy,solar power,biofuels,biomass and hydrogen

energy as technologies with“high potential”to reduce carbon levels in the atmosphere over the next

25 years.

Eric Whan of Globesean,which carried out t}le survey of“climate decision makers”.said.

“As the climate crisis deepens they could be becoming less optimistic that individual technologies

may be able to solve the problem.’’

The survey,supported by groups including the World Bank,the United Nations Environment

Programme and the Pew Center for Global Climate Change,questioned l,000 senior figures across

governments,pressure groups and companies in 1 15 countries over the last few weeks.

eonomic growth and development and significant progress in combating(与…斗争)climate change

Call be achieved at the salne time.’’

61%from 65%last year.Solar electricity generation was rated as having high—potential by 66%of  respondents,down from 74%.Support for hydrogen power was 32%,down form 36%in 2007.
