For very short distance flights, electric aircraft are already viable. For example, Harbour Air Seaplanes operates a 20 minutes flight between Vancouver, BC and Victoria, BC. They use float planes because both cities are on the coast. Their first electric aircraft should take off in a couple months.
One nice thing about electricity is that it's much cheaper than biofuels. This is because motors are much more efficient than engines, and because large generating stations are more efficient than small aircraft engines. BC is 95% hydroelectric which makes electricity even cheaper.
