There are challenges: sorting out the right mix of technologies, managing the reliability in the new large transmission grid.

存在挑战：挑选出正确的技术组合， 管理新的大型输电网的可靠性。

By interconnecting through the transmission grid, both geographically dispersed wind and geographically dispersed solar — the more interconnections you have, the smoother the overall output supply is.

通过输电网互连，地理上分散的风能和太阳能——您拥有的互连越多，整体输出供应就越顺畅。
