Risk management consultancy Norwegian classification societies have said that by 2050, renewable energy will account for the proportion of global energy supply close to 50%.

Among them, wind power will account for 14% of the world's primary energy supply, solar photovoltaic accounted for 13%.

By 2050, wind power will provide 36% of the global electricity supply, two-thirds from land-based wind power. By then, wind power costs fell 16%, solar photovoltaic costs fell 18%.

With the rapid increase in the level of global energy system electrification, DNV believes that since 2030, the global energy demand will reach a balance, into a stable period.

At the same time, by 2050, the energy sector carbon dioxide emissions will be reduced with energy efficiency and reduced reliance on fossil fuels.

But nevertheless, the classification societies believe that by 2050, the global temperature will rise by 2.5 degrees, can not achieve the 2015 Paris goal. It also sounded alarm for policymakers from governments and energy companies.

"Although the energy industry has made great efforts in the green transition over the past decade, it is clear that there is a need for more efforts to achieve sustainable development goals," said Remi Eriksen, chief executive officer of Det Norske Veritas.
