Sustainable Future

Renewable Energies: Wind, Solar, BiomassChemViews 2012. Renewables supplied over 16 % of global final energy consumption in 2010, and supply almost 20 % of global electricity.

How Wind Turbines WorkChemViews 2012. Since 1980, the diameter of the rotors of wind turbines has doubled each decade, and therefore increased the turbine height. Each generation of turbines was predicted to be the biggest, but turbines keep growing in an effort to capture the stronger winds accessible at higher elevations, and improve performance. New materials have made this possible.

Biofuels ComparedChemViews 2012. Global biofuel production grew from 16 billion litres in 2000 to more than 100 billion litres in 2010. Today, biofuels provide around 3 % of total road transport fuel globally and considerably higher shares are achieved in certain countries. Brazil, for instance, met about 19 % of its road transport fuel demand in 2010 with biofuels. But not all biofuels are created equal ?

Greenhouse Gas EmissionsChemViews 2012. CO2 emissions related to energy demand has increased by ca. 47% in the last 20 years.

Hybrid CarsChemViews 2011. Mass produced hybrids have come a long way since 2001 when the Prius was first launched in Japan. They account for just over 1 % of the global market share, while Japan and the US represent 84 % of the global hybrid market share.
