Letter: Unwanted consequences of high-speed railA report from researchers at Cal Berkeley points out that all is not peaches and cream when looking at high-speed rail vs. other transportation modes.
The researchers discovered that while high-speed rail may lower energy consumption and greenhouse-gas emissions per trip, the current electricity mix in California means that it can create more sulphur dioxide emissions, leading to environmental acidification and human health issues.
California's high-speed rail project has been promoted on many fronts. Now we can see that even with fuel savings, there are other unwanted effects.
