money that is paid by a government for renewable energy, for example energy from the sun or the wind, that someone produces on their property

Various incentives, in the form of tax credits and feed-in tariffs, mean that wind power is already cost-competitive with electricity derived from fossil fuels. 因为有税收减免和能源补贴等形式的各种激励措施，风力发电与化石燃料发电相比已经具有成本优势。

The solar feed-in tariff system has been in place in many countries for some time now. 太阳能补贴政策已经在许多国家实施了一段时间。
