11th place: New oil and gas extraction. Surprisingly, according to management consultants McKinsey, new techniques for extracting fossil fuels will have a greater economic impact than green technologies in twelve years' time. Horizontal drilling, hydraulic fracking and microseismic monitoring are expected to make the exploration and extraction of oil and gas at greater depths economically viable. Up to 6.2 million additional barrels could be available each year. Previously unused substances such as coal bed methane could also be made usable. The innovative solutions in this area will be worth between 0.1 and 0.5 trillion US dollars in 2025.
