可再生能源

一直以来，风能与太阳能始终不具备与化石燃料竞争的能力，但麦肯锡预测，随着科技进步推动可再生能源的普及和储能技术的发展，这种现状将得以改变。过去十年，太阳能发电的成本已经下降了10倍，国际能源署预测，至2050年，太阳能将取代化石燃料，成为最大的电力来源。

Renewable energy

Wind and solar have never really been competitive with fossil fuels, but McKinsey predicts that status quo will change thanks to technology that enables wider use and better energy storage. In the last decade, the cost of solar energy has already fallen by a factor of 10, and the International Energy Agency predicts that the sun could surpass fossil fuels to become the world’s largest source of electricity by 2050.
