The requirement was adopted after a tough fight at the Legislature, with soybean farmers pushing for the mandate and trucking and other transportation industry groups in opposition, citing concerns about costs and performance of biodiesel.
The state has mandated the biodiesel blend increase to 5 percent starting this spring.
Minnesota is one of three states, besides Oregon and Washington, that have biodiesel mandates.
In extreme cold weather some school districts keep the busses running all night or keep them in heated garages.
Not a good way to conserve resources.
Is the fuel problem brought on by adding biofuel to the diesel? Regular diesel can gel in cold weather. Are the school districts using the proper fuel additives and fuel filters?
Keeping the busses running when not in use must use about as much fuel as driving them for four hours or so in the daytime.
