1·But one reason it's not clear how to adapt the electricity grid to the intermittency of renewables is we're still missing information about how technologies like solar panels behave.

我们对于输电网与不稳定的再生性能源的适应性问题束手无策的一个原因，是我们始终对于太阳能电池板如何运行的科技研究一片空白。

2·We need to look at tried and tested technologies like renewables that work and can start reducing the threat climate change now.

然而，我们需要的是寻找经过实践证明的技术，可以像再生能源技术那样，在减轻气候变化威胁发挥作用，并能够立即投入使用。
