Experts note that paying attention to opportunities for improving the environment and the global economic downturn will lead to an increase in demand for "green” energy when the epidemic ends. We have experienced the same pattern over the past years. For example, after the financial crisis of 2008, President Obama signed into law the American Economic Recovery and Reinvestment Act, which provided $ 30 billion of funding for research and projects in the field of renewable energy. After the oil crisis in the early 1970s, the demand for low-fuel cars rose in the United States, which prompted manufacturers to invent new, more environmentally friendly models of cars.
