求翻译：清洁煤技术、可再生能源和新能源的开发技术相对滞后，缺乏核心技术，对国外的成熟技术依赖性较大，节能减排技术还不能广泛应用是什么意思？

Clean coal technology, renewable energy and the development of new energy technology is lagging behind the lack of core technology, mature technology dependent on foreign energy saving technology is not widely used

Clean coal technologies, renewable energy and the development of new sources of energy technology has lagged behind, and lack of core technologies, proven technology in a foreign country dependent on energy, emissions reduction technology also can be widely applied

The clean coal technology, the renewable energy and the new energy development technology relative lag, lacks the core technologies, is big to the overseas mature technical dependence, the energy conservation reduces a row of technology not to be able widely to apply

Clean-coal technology, renewable energy and development of new energy technologies is lagging behind, the lack of core technologies, dependence on overseas mature technology is large, widespread application of energy-saving emission reduction technology
