It's actually a bigger footprint if we take into account the embodied energy in the stuff we import into our country as well, and 90 percent of this energy today still comes from fossil fuels, and 10 percent only from other, greener -- possibly greener -- sources like nuclear power and renewables.
如果把每天进口的实体能量也考虑进来 这实际上是很大的能源消耗 其中90%的能源依然来自矿物能源 只有10%的能量来自其它渠道 更绿色的——可能是更绿色的——能源 比如说核能或可再生能源
