可再生能源革命并非由碳排放税或清洁能源补贴推动；而是不久就会使水力、风力和太阳能发电成本低于燃煤发电的制造成本降低的结果。
The renewable energy revolution is not being driven by a tax on carbon emissions or subsidies for clean energy; it is the result of reductions in the cost of manufacturing that will soon make it more cost-effective to generate power from water, wind, and the sun than from burning coal.
