【环球时报综合报道】一项来自英国牛津大学的最新研究显示，人类如果从化石能源转向可再生能源，到2050年可节省12万亿美元。据英国广播公司(BBC)13日报道，目前人们对于能源供应的担忧日益加剧，天然气价格也在飙升，科研人员认为，由于可再生能源的成本在下降，目前的绿色环保在经济层面也是有收益的。

B |     Beijing, Oct 16 (UNI) Chinese President Xi Jinping said on Sunday that the Communist Party of China (CPC) will implement its overall policy for resolving the Taiwan question in the new era, and unswervingly advance the cause of national reunification.



"Resolving the Taiwan question is a matter for the Chinese, a matter that must be resolved by the Chinese," said Xi at the opening session of the 20th CPC National Congress.



"We will continue to strive for peaceful reunification with the greatest sincerity and the utmost effort, but we will never promise to renounce the use of force, and we reserve the option of taking all measures necessary. This is directed solely at interference by outside forces and the few separatists seeking 'Taiwan independence' and their separatist activities; it is by no means targeted at our Taiwan compatriots," he said.



Xi said that the wheels of history are rolling on toward China's reunification and the rejuvenation of the Chinese nation. "Complete reunification of our country must be realized, and it can, without doubt, be realized!"



"We have always shown respect and care for our Taiwan compatriots and worked to deliver benefits to them. We will continue to promote economic and cultural exchanges and cooperation across the Strait," Xi said.



"We will encourage people on both sides of the Strait to work together to promote Chinese culture and forge closer bonds," he said.

UNI/XINHUA PRT。牛津大学马丁学院新经济思想研究所的多恩·法尔莫教授对媒体表示：“即使你是一名对气候变化持否认态度者，也应该赞同我们的主张。我们的关键结论就是，应该全速推进向可再生绿色能源的转型，这将为我们节省大量资金。” 这份研究报告的结果来自于对可再生能源和化石能源历史价格的对比数据，并对两者未来可能发生的变化进行建模预测。石油、天然气等化石能源的数据可以从2020年向前追溯100多年，在排除通货膨胀和市场波动影响后，化石能源的价格变化并不大。相比之下，可再生能源诞生不过几十年，数据较少，但就在这几十年里，因为科技的不断进步，也促使太阳能、风能的成本在以每年大约10%的速度迅速下降。基于该模型，这份研究预测：在投入了大量资金、形成规模经济和采用更廉价的技术后，可再生能源的价格未来将继续下跌。

C | 该研究报告的主要作者史密斯企业与环境学院的鲁珀特·韦博士表示，“扩大关键绿色技术的规模，将导致成本继续降低；我们前进得越快，节省的成本就越多。”目前，风能和太阳能已经是新建电力项目中最便宜的选择，但人们还需要研究，如果发生天气变化，导致可再生能源产量下降时，如何最好地储存电力、平衡电网等具体问题。2019年，英国时任财政大臣菲利普·哈蒙德曾在给首相的信中指出，到2050年，英国为实现温室气体“零排放”的成本将超过1万亿英镑，如此高的预期投入或将阻碍投资。(董铭)
