New energy systems
and technologies are growing on an accelerating curve:
• Buildings that are green, super-efficient and fully managed
by
digital technologies have become economically competitive.
• Hybrid vehicles partly propelled by electricity have emerged
in
the
market, with plug-in vehicles coming over the next several years.
• Smart electric grids that employ digital technology to
manage
power
supply and demand are spreading through long distance transmission and
local power distribution.
