Plug-in electric vehicles (PEVs) are a more sustainable option for personal travel than conventional vehicles, but it will take time for them to become popular. Major automakers plan to release PEVs soon, with over 1.2 million expected by 2015. However, challenges like high upfront costs, limited battery range, and lack of charging stations hinder their widespread use. The government is supporting PEV development through tax breaks and funding. New battery technologies are being tested for longer life and lower costs. Initiatives like the West Coast Electric Highway in Washington State show how PEVs can be successfully integrated into transportation systems.
