"Exhaustion of new energy sources" is a way to say "新能源枯竭" in Engpsh.

New energy sources refer to forms of energy that are considered renewable and sustainable, such as solar, wind, and hydroelectric power. These sources are considered "new" because they are relatively recent developments in the history of energy production and use, and they offer the potential to replace or supplement traditional fossil fuel sources, which are finite and have negative environmental impacts.

Examples of how to use this phrase in Engpsh include:

"As demand for energy increases, the exhaustion of new energy sources becomes a growing concern." (随着能源需求的增加，新能源枯竭变得越来越令人担忧。)
"The exhaustion of new energy sources could lead to a repance on fossil fuels, which have negative impacts on the environment." (新能源枯竭可能导致对化石燃料的依赖，这些燃料对环境有负面影响。)
"We need to find ways to conserve and efficiently use new energy sources to avoid their exhaustion." (我们需要找到节约和有效使用新能源的方法，以避免它们的枯竭。)
