From at least the late nineteenth century in Europe, there was speculation that the range of human sexual response looked more like a continuum than two or three discrete categories. Berlin sexologist Magnus Hirschfeld published a scheme in 1896 that measured the strength of an individual's sexual desire on two independent 10-point scales, A (homosexual) and B (heterosexual). A heterosexual individual may be A0, B5; a homosexual individual may be A5, B0; an asexual would be A0, B0; and someone with an intense attraction to both sexes would be A9, B9.

What did the published scheme attempt to do?
Answer: measured the strength of an individual's sexual desire

Portugal has considerable resources of wind and river power, the two most cost-effective renewable sources. Since the turn of the 21st century, there has been a trend towards the development of a renewable resource industry and reduction of both consumption and use of fossil fuel resources. In 2006, the world's largest solar power plant at that date, the Moura Photovoltaic Power Station, began operating near Moura, in the south, while the world's first commercial wave power farm, the Agucadoura Wave Farm, opened in the Norte region (2008). By the end of 2006, 66% of the country's electrical production was from coal and fuel power plants, while 29% were derived from hydroelectric dams, and 6% by wind energy.

By the end of 2006, what percentage of Portugal's energy production was from renewable sources?
