SPECIAL REPORT

Wind energy... currently meeting
3 per cent of world's energy needs

Wind could supply one-fifth of global power

LONDON, October 22, 2014

Installed wind power capacity could swell by 530 per cent to 2,000 gigawatts (GW) by 2030, supplying up to 19 per cent of global electricity, a report from a trade association and Greenpeace said.

The report entitled Global Wind Energy Outlook 2014 said installed wind energy capacity totalled 318 GW at the end of last year worldwide and provided around 3 per cent of global electricity supply. Capacity is set to grow by another 45 GW to 363 GW this year.

In some parts of the world, particularly in Europe, people have objected to wind power due to government subsidies which they claim have contributed towards rising energy bills.

But Steve Sawyer, chief executive of the Global Wind Energy Council (GWEC), said: "Wind power has become the least-cost option when adding new capacity to the grid in an increasing number of markets, and prices continue to fall."

The GWEC, which represents 1,500 wind power producers, looked at the future of the wind energy industry to 2020, 2030 and 2050 under three scenarios based on existing and future emissions reduction and renewable energy policies.

Based on International Energy Agency forecasts, it said cumulative installed wind energy capacity could reach 611 GW by 2020 and 964 GW by 2030.

Under the report's "moderate" scenario, based on existing renewable energy policies and assuming that emissions reductions agreed next year in Paris under a global climate deal will be modest, installed wind capacity could reach 712 GW by 2020, nearly 1,500 GW by 2030 and around 2,670 GW by mid-century.

That means wind energy could meet 7-8 per cent of global electricity demand by 2020, 13-15 per cent by 2030 and 17-20 per cent by 2050.

Under the "advanced" scenario, based on more ambitious growth rates and assuming that a robust global climate deal is in place, installed capacity could reach 800 GW by 2020, nearly 2,000 GW by 2030 and over 4,000 by 2050.

That means wind energy could provide 8-9 per cent of global electricity supply by 2020, 17-19 per cent by 2030 and 26-31 per cent by mid-century.

"Given the urgency to cut down CO2 emissions and continued reliance on imported fossil fuels, wind power's pivotal role in the world's future energy supply is assured," Sawyer said.

The report identified Brazil, Mexico and South Africa as areas for new growth in wind energy. Brazil is set to install nearly 4 GW this year alone, while Mexico should add around 2 GW a year for the next 10 years. – Reuters
