How electric aircraft is advancing and transforming the
industry for a zero-carbon future.

he exciting development of electric
aircraft (EA) has been referred
to as " the Third Revolution
in Aviation. " [1]
The first revolution
was the Wright brothers' first successful
powered flight, the second one, the invention
of jet propulsion which allowed
us to fly faster and farther. The growth of
aviation that followed introduced the big
carbon emission problem. The advent of
EA propelled by clean electricity marks
the dramatic transformation to zero carbon
emission for aviation, and the " third
revolution. "
EA hold tremendous potential to improve
emission, noise, and operating economics
across a range of different applications
in support of the aviation industry's
" In the span from
2016 to 2022, there
have been over 300 EA
projects and up to 200
EA startups around the
world, similar to the
renaissance of aviation
period in the early
1900s. "
goal of achieving net-zero carbon emissions
by 2050. There are, however, technology
challenges that must be overcome
for achieving this goal.
Accelerating Adoption
These revolutionary EA have already
demonstrated significant cost savings.
For example, the energy cost of the
two-seat Pipistrel aircraft per hour is at
0.9 € while a conventional Cessna twoseat
aircraft C152 commonly used for
training is approximately $34 (preUkraine
war estimate), which is equivalent
to 34× that of the Pipistrel Alpha
Electro.[2]
An estimate of the per hour
total operating cost for the C152 vs. the
Alpha Electro is approximately 3.6:1;
