As the Red Line nears its Sept. 1 opening date, more scrutiny is being put on the success of the bus rapid transit line.

One major issue is the range of the electric buses. Last month, IndyGo shared testing data that confirmed the buses made by manufacturer BYD are falling short on the promised range of 275 miles.

Taxis in the Norwegian capital, Oslo, are set to use wireless fast-charging technology to keep them running.

In an announcement Thursday, Finnish energy firm Fortum said it would work with the City of Oslo and Momentum Dynamics, a U.S. company, to build the system.
