[Dai Sipan, Chief Economist of bp Group: structural shortage of Natural Gas will still exist in the next 3-4 years] Spencer Dale, Chief Economist of bp Group, said in a recent media group interview in Beijing: "We know that wind and solar energy are growing substantially, but they have not been able to offset the decline in natural gas supply, so it is possible that natural gas will still be in shortage in winter. Whether there is a shortage depends on whether the winter is cold, so my prediction is that the structural shortage of natural gas will remain in the next 3-4 years, until we see a new supply of LNG on the market, or a substantial increase in alternative energy sources, such as wind and solar installed capacity. But it takes time for wind and solar to build a new project, and it takes 4-5 years for a new LNG project to be built, so it takes a while to prepare for LNG to be sold on the market. Therefore, it is too early to say whether the crisis is over. If the winter is too cold, we will see a sharp rise in natural gas demand. "
