It is difficult to compare the costs of different energy sources, because many benefits of renewable energy (such as pollution-free and unlimited supply) are not universally accepted. However, it is important to try and prefer to use fossil fuel sources like "comparison with wind", so it is a good guide for bidding obligations to enter non-fossil fuels, contract 15. In the last round of everything, the Scottish order was the third, and the wind vane of about 1000 MW was below 2.8 pence per watt (p/kWh) -3.2 p/kWh. In 2004, the lowest price was about 220 p/kWh.

However, even ignoring these vital benefits, the following figure shows that surface wind energy is competing with new coal-fired power plants, and the cost is newer than that of current nuclear power.

Attention. The price of fossil fuel power generation has been used in the following picture in the recent government white paper-unless it is gasoline. In this case, the recent price trend has been taken into account, so the possible cost of producing a new factory is close to 3p/kwh. In the early autumn of 2004, the price of gasoline rose in the futures market, which will lead to higher costs.
