Not one individual or a group, but Sweden as a whole country has merged as a winner for making the best of bio-gas—a concept that has been blissfully ignored by many countries until now. It is estimated that 25% of Sweden’s energy consumption is derived from biomass. And Linköping, Sweden’s fifth biggest city, is driving green as all the buses and garbage trucks run on bio-gas. And that’s not all, they also have a bio-gas-powered train line and some private cabs running on bio-gas. And Amanda, believed to be the world’s first bio-gas train, started chugging along the southeast coast of Sweden three years back. Moreover, it isn’t unusual to find a green and cheap bio-gas option at local gas stations.
