Indoor air pollution poses an exceptionally high risk in China, where more than 70 percent of households use solid fuels such as wood, biomass, and coal for heating and cooking. China, where over half of all men smoke, is also a leading market both for world tobacco production and for cigarette consumption...
...coal gasification incentives on two underwhelming arguments. First, advocates point out that the technology reduces emissions of certain air pollutants such as mercury, nitrogen oxides, and sulfur dioxide. Yet this apparent concern for environmental consequences obscures a lesser-known fact: Unless coal is replaced by significant amounts of biomass, gasification plants emit as much CO2 as traditional plants. To combat high emissions, Massachusetts’s Senate bill requires that gasification emissions match those of natural gas. What looks like a step in the right direction remains problematic: Ultimately, incentivizing the burning of any fossil fuel, coal or natural...
...have a greener story to tell than do any other biofuel producers. They provide 45% of Brazil's fuel (all cars in the country are able to run on ethanol) on only 1% of its arable land. They've reduced fertilizer use while increasing yields, and they convert leftover biomass into electricity. Marcos Jank, the head of their trade group, urges me not to lump biofuels together: "Grain is good for bread, not for cars. But sugar is different." Jank expects production to double by 2015 with little effect on the Amazon. "You'll see the expansion on cattle pastures...
Additional renewable fuel from an agricultural waste-burning biomass generator will help power a site larger than two football fields...
...energy from renewable resources by 2020. (Seventy percent of mainland China's energy comes from coal today.) In another desert village, drought-resistant shrubs called sand willows are being planted to keep encroaching sands at bay, but there are also plans to start processing them in a biomass thermal power plant, which will burn the willows to generate electricity and create another clean source of fuel...
