电力市场的自由化和增加可再生能源在发电组合中的比例的政治意愿为“绿色”能源创造了有利条件。苏格兰风能和海洋能源资源特别丰富，这项研究的论点是，该国可以满足其未来可再生能源电力需求的很大一部分。在这项研究中，在苏格兰的陆上风，海上风，波浪和潮流资源的位置和物理，环境和规划限制，他们的发展进行了映射，并在可行的位置发电的寿命生产成本进行了预测。对于许多经济排名的可再生能源发电场景，分析了连续三年内的每小时功率时间序列。该研究表明，尽管可再生能源的性质多变，但到2020年，可再生能源可以平均满足苏格兰40%的电力需求。该研究还表明，一年中会有许多小时可再生能源发电与需求不一致，导致过剩或短缺。来源多样化及其地理分布是实现更好匹配的措施。通过专门调度水力和抽水蓄能电站以及管理电力系统，可以进一步缓解。
The liberalisation of the electricity market and the political will to increase the percentage of renewable energy in the generation mix has led to favourable conditions for "green" energy. Scotland is particularly rich in wind and marine energy resources and the thesis of this study was that the country could meet a significant portion of its future demand for electricity from renewable sources. In this study, the location of onshore wind, offshore wind, wave and tidal current resources in Scotland and the physical, environmental and planning constraints for their development were mapped and the lifetime production costs of electricity generation at feasible locations were predicted. For a number of economically ranked renewable generation scenarios, hourly time series of power over a consecutive period of three years were analysed. The study showed that despite their variable nature, renewable sources could be developed so that they supply, on average, 40% of the Scottish demand for electricity by 2020. The study also showed that there will be many hours in a year when renewable generation does not coincide with demand resulting in excess or shortfall. Diversification of sources and their geographical dispersion are measures to achieve better matching. Further mitigation is possible through dedicated dispatching of hydro and pumped storage plant and through management of the power system.
