阅读下面的文章回答。
按照规划,2020年我同新能源(包括可再生能源)在总能耗中的比例是15%,石油、煤炭等不可再生的传统能源比例仍达85%。在此背景下,“节能提效”被提到了我国发展低碳经济的首选位置上。
低碳经济是以低能耗、低污染、低排放为基础的一个经济模式,是能源的高效利用和清洁能源的开发。其中,新能源的发展前景被市场看好。但目前来看,新能源尚无法替代传统的化石能源,化石燃料仍将住我国能源构成中居主导地位,新能源还只是作为化石能源的补充角色而存在。此外,从节能减排的投资效果看,目前提高能效对“低碳”的贡献也远甚于新能源。来自国务院发展研究中心的一份研究报告显示,能效项目“万元投资”形成的节能能力为5吨标准煤/年左右,而风能和太阳能项目投资形成的节能能力不足1吨标准煤/年,能效项目投资有明显的优势。
从全世界的情况分析,节能在今后实现低碳经济过程中总的贡献率将达到60%-70%。然后才是依靠能源结构的调整,以及到没有其他办法的时候采用造价昂贵的碳封存技术。业内人士指出,当前我国发展低碳经济,应把大力开展节能放在首位,从节能和减排的一致性方面强调低排放发展;其次,把大力开发传统能源中相对低碳的能源如天然气、核能和水电等作为近期调整能源结构、减少排放的主要发展方向。
不过,目前我同地方政府所走的“低碳”路径与此并不一致。据不完全统计,目前在中国已有近20个省市提出要打造新能源基地,上百个城市提出把新能源作为经济发展的增长点。不少地方认为,发展低碳经济就是发展新能源。其实,低碳经济不能等同新能源产业,新能源产业只是“低碳经济”中的一部分。并且,大规模地、盲目地上马新能源项目,更有可能造成资源浪费。

根据上述材料,我国发展低碳经济的战略不包括______。

A.大力发展新能源

B.不断提高能效

C.努力减少排放

D.尽快开采化石燃料
