A estrutura de concorrência perfeita, na visão neoclássica, é referência teórica para a eficiência econômica, pois, a um tempo, é capaz de compatibilizar os interesses público e privado, e os de consumidores e produtores. Em princípio, tal modelo propiciaria a melhor alocação de recursos e se coadunaria com a atomização do mercado.

Europe and North Africa could be powered solely by

renewable electricity by 2050 through the implementation of a
"SuperSmart Grid", according to a report issued this week by global
advisory firm PricewaterhouseCoopers (PwC).
According to Energy Source, the achievement of 100 per
cent renewable electricity would address energy security and supply
concerns, while decarbonizing electricity generation and reducing
energy poverty, according to the study.
The proposed SuperSmart Grid would allow load and
demand management for power independently of where and when
the electricity is generated.
The system would capitalize on natural resources and
established weather patterns and would incorporate: southern
Europe and North Africa's solar power potential; the hydro
capability of Scandinavia and the European Alps; onshore and
offshore wind farms in the Baltic and the North Sea; Europe's
potential for tidal and wave power; and biomass generation across
the continent.
According to Gus Schellekens, director of sustainability
and climate change at PricewaterhouseCoopers, Europe is now at
a crossroads, where the choice and ability to achieve renewable
power at scale is evident. "Opportunities to use clean and affordable
natural sources of electricity have been flirted with over the past
150 years. This study lays out a clear framework of how this time
could be different", he says.
The dominant source of European power is fossil fuels (55
per cent), while nuclear power provides 30 per cent and 15 per cent
is derived from renewable sources. According to the PwC study, a
renewables-powered Europe would change the landscape for
consumers and business. Electro-mobility could be introduced on
a mass scale, eliminating the carbon costs of day-to-day transport
for people and goods.

It is possible to infer from the text that

electro-mobility introduced on a mass scale can make everyday transport for people and goods cheaper.
