We humans have an innate tendency to overestimate the progress that can be made in the short term (leading to disappointment) and underestimate the progress that has been made or can be made in longer timespans.
Take for instance sustainable energy.
The latest UNEP report Global Trends in Sustainabel Energy Investing, 2009 has a stunning conclusion.
2008 was the first year that new power generation investment in renewables was greater than investments in fossil-fueled technologies.
More than $140-billion went into renewables worldwide in 2008, while $110-billion went into fossil fuels.
