這是美國聯邦環保署官網上對於「綠能 Green Energy」、「再生能源 Renewable Energy」、「傳統能源 Conventional Energy」能源類別的規類認定。
特別是對於環保生態的有益程度來說,美國聯邦環保署很明確的認定綠能優於其他各種能源類別,是對於環保生態最有益的能源類別,其次為再生能源類別,對於環境生態最不友善的類別是傳统能源。傳統能源包括兩大項目,分別是化石燃料能源(即火力發電類別)以及核能。
美國聯邦環保署解釋,核電在整個生命週期的過程中,在起源的採礦、提煉、製造核燃料的過程中,以及核後端處理的漫長過程中(包括核電廠廢爐除役過程、核廢料短中長期各階段的處理、貯放過程)都無可避免的會對環境生態造成負面影響。
What is Green Power? (這是USEPA 美國聯邦環保署官方網站上對於"綠電(Green Power)的符合資格認定的說明與解釋的完整內容)
The U.S. energy supply is composed of a wide variety of energy resources; however, not all energy resources have the same environmental benefits and costs.
Green power is a subset of renewable energy and represents those renewable energy resources and technologies that provide the highest environmental benefit. The U.S. voluntary market defines green power as electricity produced from solar, wind, geothermal, biogas, eligible biomass, and low-impact small hydroelectric sources. Customers often buy green power for its zero emissions profile and carbon footprint reduction benefits.
Renewable energy includes resources that rely on fuel sources that restore themselves over short periods of time and do not diminish. Such fuel sources include the sun, wind, moving water, organic plant and waste material (eligible biomass), and the earth's heat (geothermal). Although the impacts are small, some renewable energy technologies can have an impact on the environment. For example, large hydroelectric resources can have environmental trade-offs on such issues as fisheries and land use.
Conventional power includes the combustion of fossil fuels (coal, natural gas, and oil) and the nuclear fission of uranium. Fossil fuels have environmental costs from mining, drilling, or extraction, and emit greenhouse gases and air pollution during combustion. Although nuclear power generation emits no greenhouse gases during power generation, it does require mining, extraction, and long-term radioactive waste storage.
The following graphic depicts how the U.S. Voluntary market defines green power based on its relative environmental benefits.

#新加坡辣妹更嗆辣
新加坡總理夫人,何晶於上周發表新加坡應該發展核電的言論,她非常了解新加坡在減緩溫室氣體上的不足,以及新加坡在發展核電上的潛力,畢竟新加坡的主要能源為天然氣,且未來冷凍空調需求會持續成長。而她也同時知道福島事故的發生原因,認為要從檢討實務面以科技來改善缺陷...不過從她的學術以及實務背景來看(新加坡工程名譽院士),好像也不會太意外有這樣的言論出現,根本新加坡辣妹一個。
當然新加坡短期內可能還沒有核電廠建置的計畫,2012年的評估結果為不適合,但是相關的研究仍在進行中,2014年起投入了相當多的研究能量於核電技術研發。

SG decided in the early days, no more coal fired power plants bcos of the pollution they bring.
And we switched to gas as soon as it was available, bcos it is less pollutive.
In terms of carbon dioxide emission, coal, oil and gas would be similar.
But in terms of air pollution and various particulates from the fuel composition, gas is the cleanest.
We also considered nuclear.
Pioneers like Dr Tay Eng Soon were attached to the UK Atomic Energy Agency for training.
But singov then decided it was too risky since we have just this one small SG island. And so the team was disbanded.
Dr Tay Eng Soon went on to teach in the university, and later founded the Defence Science Organisation for Mindef, before ending as a politician who transformed vocational training for SG.
But the current generation of nuclear power generation is much safer than the 1st generation of nuclear power plants like the Fukushima plant.
Fukushima relies on active power source to maintain the cooling - lose that power source and there will be a serious meltdown risk.
Current generation designs are based on a fail safe approach. When power fails, the system remains safe.
This is similar to another concept called fail soft approach. In a fail soft approach, the system continues to be operational in a degraded mode, which gives time for corrective action.
With almost all Asean countries wanting to have nuclear power plants at some foreseeable future, it is important that Asean begins to do research especially on safety and security aspects well beforehand to build up professional and scientific capability and capacity to handle nuclear plants well.
An example of emerging security risks would be the cyber risks of an external agency taking over and messing a power plant via software and remote entry.
Newer nuclear options are on the horizon, not eminent, but within decades.
Overall, for a greener earth and to reduce carbon emissions, we must master and adopt nuclear energy as a key solution.
For now, it is better than developed and more capable nations step up their nuclear power capacity.
This will reduce the demand for fossil fuels, and lower the overall carbon emissions.
At the same time, developing economies can do their part to switch away from coal to cleaner gas or greener renewables.
