Will high-speed rail use renewable energy?

This high speed train could be the first to be powered entirely by renewable energy. California's long-awaited high speed train will be solar powered, according to the California High-Speed Rail Authority. It's been a rocky road so far for the California High-Speed Rail Authority's promising new project.

Building high-speed rail systems require steel and concrete, the manufacturing of which typically generates greenhouse gases. Trucks, bulldozers, and other construction site equipment also consume energy. Thus, during their long construction phases, high-speed rail projects add greenhouse gases.

It Won't Help and May Hurt the Economy. Studies have found that high-?speed trains can generate new economic development near the stations where the trains stop. However, the same studies show that economic development slows in communities not served by such trains.

The California HSR, for example, will remove 12 billion pounds of carbon dioxide per year by 2030 because it uses electricity generated from wind, solar, and other renewable resources. In addition, California's HSR will save 12.7 million barrels of oil by 2030.

46.0 g CO2 / pkm The analysis concludes that the carbon footprint of high speed rail including operation, track construction and rolling stock construction is about 14 to 16 times less than transport by private car or airplane.

Rail currently provides low-cost long-distance transportation for heavy freight, which HSR is unlikely to do given its higher costs and the track damage caused by heavy trains. HSR may compete with the domestic air cargo industry, though its historically poor profitability suggests lackluster returns.

High-speed rail is generally regarded as the pinnacle of attractive and green transportation. But all too often, it makes train travel more expensive and less flexible. In the end, costly high-speed lines may just push more people into cars.

High-speed train revolution China has built around 26,000 miles (42,000 kilometers) of dedicated high-speed railways since 2008 and plans to top 43,000 miles (70,000 kilometers) by 2035. Meanwhile, the United States has just 375 route-miles of track cleared for operation at more than 100 mph.

That works out to $200 million a mile for hilly areas. At these costs, Obama's original high-?speed rail plan would require well over $1 trillion, while the USHSR's plan would need well over $3 trillion. Building a system longer than China's would cost at least $4 trillion.
