Constellation能源公司稱，該公司正為弗吉尼亞州及新澤西州的聯(lián)邦監(jiān)獄安裝太陽能發(fā)電系統(tǒng)，以減少能源使用和溫室氣體排放。
    Constellation公司說，弗吉尼亞州Fairton 及 Petersburg 兩大監(jiān)獄的項(xiàng)目都自行支付費(fèi)用，但無前期花銷。
新澤西監(jiān)獄系統(tǒng)希望利用太陽能電源、智能控制及其它能源技術(shù)削減監(jiān)獄27%的能源利用及42%的水的使用。在弗吉尼亞州，生物熱能、太陽能和電動(dòng)車都在積極的改進(jìn)當(dāng)中。        
    白宮今日表示，它希望從如員工駕車等間接來源減少30%的溫室氣體排放量。隨后，個(gè)各聯(lián)邦機(jī)構(gòu)出臺(tái)法令，減少包括建筑物等直接溫室氣體來源，計(jì)劃在未來10年內(nèi)減排28%。

 BALTIMORE ― Constellation Energy says it is working with federal prisons in Virginia and New Jersey to cut energy use and greenhouse gas emissions.
Constellation says the projects at prisons in Fairton and Petersburg, Va., will pay for themselves with no upfront costs.
    Solar power, smart energy controls and other technologies are expected to cut energy use 27 percent and water use 42 percent at the New Jersey prison. In Virginia, biomass heating, solar power, and electric vehicles are among the improvements.
    The White House said today it wants to cut greenhouse emissions from indirect sources such as employee driving 13 percent. That follows a directive that federal agencies cut pollution from direct sources, including buildings, 28 percent in the next decade.
