The Energy Game is Rigged: Fossil Fuel Subsidies Topped $620 Billion in 2011
The energy game is rigged in favor of fossil fuels because we omit the environmental and health costs of burning coal, oil, and natural gas from their prices. Subsidies manipulate the game even further. According to conservative estimates from the Global Subsidies Initiative and the International Energy Agency (IEA), governments around the world spent more than $620 billion to subsidize fossil ...

A long year in the life of the US coal industry
With concerns about climate change mounting, the era of coal-fired electricity generation in the United States may be coming to a close. In early 2007, a US Department of Energy report listed 151 coal-fired power plants in the planning stages in the United States. But during 2007, 59 proposed plants were either refused licenses by state governments or quietly abandoned. In addition, close to 50 ...

Contrasting physical properties of black carbon in urban Beijing between winter and summer
Black carbon )BC) is known lo have major impacts on both human health and climate. The populated megacity represents (he most complex anthropogenic BC emissions where the sources and related impacts are very uncertain. This study provides source attribution and characterization of BC in the Beijing urban environment during the joint UK-China API III (Air Pollution and Human Health) project, in ...

Biomass Ready Coal Fired Plants and Massive Tree Planting will be the Compromise Climate Change Solution
Coal provided 26 percent of the additional power generation last year and 38 percent of all generation. There are 500,000 MW of new coal fired generation in the planning stage. This is more than was ever installed in the Americas and Europe. So any programs to reduce coal fired generation on these two continents to zero would eliminate less than is being added elsewhere in the world. The ...

Thermal behaviour study of senakin coal and Refuse Derived Fuel (RDF) blends during pyrolysis using thermogravimetric analysis
Preliminary Thermogravimetric (TG) studies of pyrolysed Refuse Derived Fuel (RDF)–coal blends (20 to 80%) at various heating rates, 20, 40, 60 °C•min–1 have been performed to develop an efficient locally sourced renewable solid fuel. The characteristics of the coal/RDF blends followed those of the parent fuels in additive manner. Among the tested blends, 50:50 blends showed the optimum blend ...

AMETEK Land - World Coal - Beat the Heat
Between the time a piece of coal is dug out of the ground and is burned in a power plant boiler, it has been through many stages of transportation and storage. One of the advantages of coal as a fuel for power generation is the ability to store substantial quantities on site. This provides a strategic buffer of at least one month's fuel supply, which can be valuable if there is a short- or ...

Shale Gas: Time to look before we leap any further
Shale gas is a game-changer for global energy supply. It is already transforming the U.S. energy outlook, and is expected to deliver over 40% of domestic gas production by 2025 (Figure 1). Other countries and regions, notably Europe and China, may soon follow suit, in a repeat of the early 20th century oil rush. Opinion is bitterly divided, however, over the environmental risks and benefits of ...

Efficiency and the not-to-be-ignored gas-fired plant
Carbon dioxide emissions dropped significantly in the US in 2009. The economy played an obvious role; not so obvious was the influence of power generation and its increasing efficiency. CO2 emissions have been trending down for the last decade by about 0.9%. But the 2009 drop was far more dramatic -- 7% -- the largest decline since the Energy Information Administration began keeping ...

Ban the Bulb: Worldwide Shift from Incandescents to Compact Fluorescents Could Close 270 Coal-Fired Power Plants
BAN THE BULB: Worldwide Shift from Incandescents to Compact Fluorescents Could Close 270 Coal-Fired Power PlantsOn February 20, 2007, Australia announced it would phase out the sale of inefficient incandescent light bulbs by 2010, replacing them with highly efficient compact fluorescent bulbs that use one fourth as much electricity. If the rest of the world joins Australia in this simple step to ...
