2019年1-6月份，电力行业运行平稳，全国电力供需总体平衡。从主要运行指标来看，电力、热力生产和供应业固定资产投资同比仍处于负增长区间，电网投资同比继续大幅下滑，电源投资同比保持增长态势。全国电源新增发电装机容量同比继续下降，全国发电设备容量低速增长，全社会发电量增速同比明显回落。

目前，锂电池是发展主流，但频发的安全问题引人担忧，且能量密度未来将触顶；固态电池有望突破密度限制，且安全性能较高，未来或将更好地解决电动汽车续航里程问题。

在国家可持续发展战略引导下，经过多年发展，我国已成为全球规模最大的风能市场，培育了完整的风电产业链体系，创新能力和国际化程度不断提升，产业政策体系不断完善，实现了显著的经济社会效益。近年来，可再生能源发电成本大幅下降，可再生能源补贴逐步退坡，可再生能源配额制度实施在即，风电平价上网时代即将来临，再加上风电开发布局向低风速地区转移，分散式风电和海上风电稳步推进，我国风电产业发展正面临新的发展形势，风电产业发展在技术创新、商业模式、市场布局、国际合作等方面都面临着前所未有的挑战和机遇。

The United States downstream industry accounted for 18.8% of the global refining capacity and witnessed a CAGR of 0.92% between 2013 and 2018. The Gulf Coast region is the largest refining center in the United States and is home to approximately half of the country’s refining capacity. As of 2018, the Gulf Coast accounted for 45% of total petroleum refining capacity and 51% of total natural gas processing capacity in the United States. The US Gulf Coast region is expected to witness a fresh wave of investment in the downstream business, during the forecast period. In 2018, Total SA planned to build a new petrochemical plant of capacity 1 million metric ton per year of an ethane cracker at Port Arthur, Texas. The petrochemical plant involves an investment of USD 1.7 billion, and it is anticipated to commence production by 2020.
