Wind could generate 18% of global electricity by 2050

The International Energy Agency says $150 billion per year would be needed to achieve increase

Electricity generated from wind could soar from 2.6% today to 18% of the world’s electricity by 2050, according to the International Energy Agency.

Its latest Wind Power Technology Roadmap says the industry will need $150 billion per year to achieve this. Current investment is hovering around the $80 billion mark.

Wind power deployment under this vision would save up to 4.8 gigatonnes of CO2 emissions per year by 2050, equivalent to more than the current European Union annual emissions.

China, which has doubled investment in renewable energy between 2004 and 2012, would provide the largest reductions.

Since 2008, wind power deployment has more than doubled, approaching 300 gigawatts (GW) cumulative installed capacities led by China (75GW), the United States (60GW) and Germany (31GW).

Wind power now provides 2.5% of global electricity demand – and up to 30% in Denmark, 20% in Portugal, 18% in Spain.

“While world leaders pay lip service to combating climate change, what they are actually doing is subsidizing CO2 emissions to the tune of US$110/tonne. Fossil fuel energy subsidy reform could take us a long way towards protecting the climate,” Steve Sawyer, secretary general for the Global Wind Energy Council (GWEC) told RTCC.

Parity

The cost of land-based wind power is close to competitive with other sources of electricity. Offshore wind is currently expensive and technically challenging, but has an important long-term potential, according to the IEA.

In Australia and Brazil, wind energy is already cheaper than conventional energy sources.

Some European countries already draw 15-30% of their electricity from wind power, thanks to improvements in forecasting, increased interconnections, demand-side response and storage.

Turbines are getting higher, stronger and lighter, while masts and blades are growing even faster than rated capacity, allowing them to capture lower-speed winds and produce more regular output.

The GWEC believes wind could provide 1,000GW by 2020, provided the necessary financial support and policy stability is provided.

    Financial Support is nice when prices are competitive…
    Why is everybody so opinionated and nobody apprechiates the need for a sound mix of energy sources, including nuclear?

    Wind Subsidy farms are extremely effective at transferring money from the poor freezing masses in fuel poverty to the rich landowning classes.

    That isn’t their only trick though, they are also pretty good at killing raptors and bats, a good one can slice up 5 a day – that’s 1825 per year.

    Then there is the variability of the wind cubed. I.e. if windspeed halves the energy available drops to 0.5 x 0.5 x 0.5 = 1/8th. This leads to having CCGT plants idling to follow the variations, which kills their efficiency so much that you end up burning more fuel _with_ the wind subsidy farms than without them.
