(29,798 posts)11. No, you used 30 years to fudge the numbers
Recent trends demonstrate an extremely clear change in direction. Globally "investment in renewable energy power generation was $40 billion greater than investment in fossil fuels in 2011".
...Total renewable power capacity grew by 8 percent in 2011, reaching over 1,360 gigawatts (GW) of installed capacity by year-end. Renewable energy technologies now account for 16.7 percent of total final energy consumption and over 25 percent of the worlds installed power-generating capacity...

...Solar and wind continue to dominate investment in new renewable capacity. Global use of solar and wind energy grew significantly in 2012. Solar power consumption increased by 58 percent, to 93 terrawatt-hours (TWh), while wind power increased by 18.1 percent, to 521.3 TWh.
Global investment in solar energy in 2012 was $140.4 billion, an 11 percent decline from 2011, and wind investment was down 10.1 percent, to $80.3 billion. Due to lower costs for both technologies, however, total installed capacities still grew sharply.
Solar and wind energy investments were down slightly in 2012, though installed capacities still grew sharply (Source: BNEF).
Solar photovoltaic (PV) installed capacity grew by 41 percent in 2012, reaching 100 gigawatts (GW). Installed PV capacity has grown by 900 percent since 2007. The countries with the most installed PV capacity today are Germany (32.4 GW), Italy (16.4 GW), the United States (7.2 GW), and China (7.0 GW). Concentrating solar thermal power (CSP) capacity reached 2.55 GW, with 970 megawatts (MW) alone added in 2012...

OP
Why didn't Japan build their own airliners instead of buying from Boeing / Airbus?

Agreed. I just wanted to get the idea out there, and this was as good a place as any.

At least you've stopped trying to beat us to death with Mark Z. Jacobsen...
