提高電價在美國是難以「統一」運作,各州有不同的電力公司與系統,且多為私營公司,在標榜自由市場經濟的社會,油電價格由市場供需情況調節,聯邦能作的只是以政策來鼓勵各州發展綠色替代能源。目前大約有卅州有自定的綠能目標,但達標率有點令人洩氣。
現在是聯邦大頭頭對綠能的承諾沒法落實,卻只關注要怎麼挖煤採油,真讓人臉綠。歐洲在推動綠能上比較積極,但各盟國達標率有不小的差異,請看EU網站的宣告:
The EU aims to get 20% of its energy from renewable sources by 2020. Renewables include wind, solar, hydro-electric and tidal power as well as geothermal energy and biomass. More renewable energy will enable the EU to cut greenhouse emissions and make it less dependent on imported energy. And boosting the renewables industry will encourage technological innovation and employment in Europe.
