内蒙古某项目有150-kW的光伏阵列，扣除传输和转换损失每年产生210,458 kWh的电量。电的虚拟单价是$0.092/kWh（￥0.57/kWh），查阅商业建筑能耗调查（CBECS）数据库得出整个建筑每年能源费用是$60,129（￥372,800）。请问可再生能源系统产电百分比是多少？ A project in Inner Mongolia has a 150-kW PV array that will produce 210,458 kWh of electricity per year after transmission and conversion losses. The virtual rate for the electricity generated is $0.092/kWh（￥0.57/kWh）. The total building annual energy cost as determined from CBECS is $60,129. What percentage of renewable energy will the system produce?
A: 28%
B: 55%
C: 29%
D: 32%

参考答案: D

本题解释:
正确答案：D
解析：可昆提醒：210,458 kWh x $0.092/kWh = $19,362, $19,362/$60,129 = 32%
KKECO notes: 210,458 kWh x $0.092/kWh = $19,362, $19,362/$60,129 = 32%
