Does Daylight Savings Time Save Energy 是否日光节约时间节约能源

Daylight savings time kicks in here in the United States this weekend.  That’s almost a full month earlier than in the past.  Does this really save energy?日光节约时间开始在这里，在美国本周末，这几乎是全面一个月前比，在过去，这是否真的节省能源？

A recent study conducted by Matthew Kotchen and Ph.D.最近的一份研究报告所进行的马修kotchen和博士学位 student Laura Grant from UCSB indicates that it costs Indiana residents approximately an additional $8.6mm in utilities when they started observing DST.  That’sa pretty significant cost.学生劳拉格兰特从ucsb表明，它的成本印第安居民约1美元的额外8.6毫米在事业当他们开始观测的DST 。 that'sa相当显着的成本。

What’s the KM angle?  Maybe there are not cost benifits to Daylight Savings Time, but some people think there are social benefits; less crime, fewer fatal auto accidents, and more outdoor recreation time.什么样的角度公里？也许是没有成本效益，以日光节约时间，但有些人认为是有社会福利;减少犯罪，减少致命的汽车意外，更多的户外康乐活动的时间。

What do I think?我该怎么办觉得呢？ I just don’t want to lose that hour this weekend.我只是不想失去这个小时在本周末。
