The proliferation of handheld devices has led to developments in the field of the gas detector, which has considerably widened the scope of application across multiple end-user segments. The government regulations across the world are increasingly becoming stringent in both emission control as well as labor safety, which is driving the demand for gas detectors. Industrial production process not only involves the use of various gases but also shares a considerable share of the overall environmental emissions. The government regulates leakage of such gases, and this is where the demand for gas detectors is increasing. For instance, the EU incorporated Directive 2010/75/EU an instrumental regulation in controlling pollutant emissions into the atmosphere by industrial installations. The governments across the world and political bodies are increasingly setting targets to reduce the emission of greenhouse gases. For example, the EU has set itself a goal of net-zero greenhouse gas emissions by 2050. Also, countries, such as China, the United States, India, and Russia, are increasingly adopting stringent regulations to tackle emission rates. Moreover, the government regulations for workplace and labor safety are increasingly becoming stringent, and adherence to such rules is vital in business continuity for organizations. According to the International Labor Organization (ILO) estimates that 4% of the gross world product is expended on worker accidents, and the percentage increases even further if we take into account the work-related health problems.

受新冠肺炎疫情影响，今年春节后复工复产进度明显滞后，用电需求疲软，但随着复工复产推进我国用电需求快速恢复，叠加水电出力偏弱影响，火电电量和出力表现亦呈现出环比改善趋势，5 月份火力发电量同比增长9.0%，增速较上月提升7.8个百分点；5 月份火电利用小时首次实现年内正增长，单月同比增加21 小时。

1-5 月，全社会用电量27197 亿千瓦时，同比下降2.85%，降幅逐渐收窄。5 月用电量增速继4 月由负转正（+0.7%）后显著回升至4.6%，此前1-3月用电量同比分别下降5.9%、10.1%、4.2%。

2020 年7 月，建议三条主线布局电力板块：1）火电板块估值低、受益煤价下行，关注：华能国际、华电国际；2）水电板块股息率高、配置价值突出，关注：长江电力、湖北能源；3）风力和光伏板块市场回暖、政策保障，关注金风科技、福能股份、林洋能源。整体维持“同步大市”评级。
