摘要：Dependence on petroleum has global consequences with regard to supply constraints, energy security, and economic impacts, along with major consequences for climate change and other environmental problems. Maine is at a particular disadvantage due to its reliance on home heating oil and transportation fuels in this rural state. In this article, Elizabeth Wilson analyzes the global petroleum industry and the challenges and solutions ahead for the U.S. and Maine as we seek to reduce dependence on fossil fuels and develop other cleaner and cost-effective energy sources.
