Aviation ponders electric aircraft

OSLO - Will we someday be able to fly without the guilt of causing environmental damage? A handful of firms and regulators hope that the electric revolution in cars will also take to the skies, helping the industry cope with an expected boom in travel and reduce greenhouse gas emissions.

"Many people say that we must get rid of air transport because we will never be able to deal with emissions and noise, but this is an outdated approach," said Norwegian Transport Minister Ketil Solvik-Olsen.

Norway, the largest oil and gas producer in western Europe, is paradoxically a pioneer in the field of electric transport. The Nordic nation aims for all new vehicle registrations to be zero emission by 2025 and launched a first electric ferry in early 2015.
