Its new chips also use 75% less energy的表达正确吗

2 Its new chips also use 75% less energy的表达正确吗

我在教辅书上看到一句话：

Its new chips also use 75 percent less energy.

我看不懂这句话，感觉原句是不是应该写成：

Its new chips also use less than 75 percent of energy.

请专家老师指点，谢谢老师！

假设旧芯片耗能1瓦电。Its new chips also use 75 percent less energy. 该句意思为新芯片耗能减少70%，即只耗能0.25瓦。Its new chips also use less than 75 percent of energy. 这个句子的意思是：新芯片耗能不到旧芯片的耗能的75%，即实际耗能为0.74瓦。这就是二个句子意思的差别。less than 75 percent=不到/少于75%；75% less=少了/减少75%。
