Indeed, a sustained decline in oil prices would not only make renewable energy sources less competitive now; it would impede their future competitiveness by discouraging research and investment. More generally, it would reduce the incentive for consumers, companies, and governments to pursue more energy-efficient practices.
事实上，石油价格的持续下跌不但让可再生能源资源竞争力下降；还阻挠了研究和投资，使它们的未来竞争力进一步削弱。更一般地，这抑制了消费者、公司和政府追求能源节约型行为的激励。
