With the development of new energy, the ratio of which is increased slightly from 1980 to 1990.有错吗

有错, 从句子还未完整。

更正 ：

With the development of new energy, the ratio which is slightly increased from 1988 to 1990 has been duly recorded。

还原 :

With the development of new energy, the ratio which is slightly increased  ... 

With the development of new energy                是短语

the ratio has been duly recorded                        是主句

which is slightly increased from 1988 to 1990   是子句

of 可省略。
