Support for renewable energy technology to figllt global warming is weakening in the face of
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．
Almost three—quarters of the experts agreed in the survey that“equitable(公平的，平等的)e—
eonomic growth and development and significant progress in combating(与…斗争)climate change
Call be achieved at the salne time．’’
Asked to rate the likely Success of low—carbon technologies in the mid—term，they showed
less confidence than a similar survey 12 months ago．Support for offshore wind farms，was down
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．
The respondents also warned that a deep recession(衰退)would make a new global deal on climate harder to achieve．Some 44％agreed that the current economic crisis will significantly delay orcompromise the“achievement of effective climate change agreements．’’
