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 ...

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 ...

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 ...

Biomass Pellet Fuel Is A Renewable New Energy Wood Pellet Machine
With the requirement of environmental protection, the development of biomass energy has been promoted, so the biomass wood pellet machine is an indispensable device. Biomass pellets belong to biomass energy, but there are many people who do not know the requirements of biomass pellet machine pelletization. Knowing what is required for pelletization can produce high-quality biomass pellets, so ...

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 ...

The right time for solar augmentation for the CSP industry
While demand for concentrated solar power augmentation of coal-fired plants is picking up with the recent announcement of a 5MW addition to a coal plant in Chile by GDF Suez & Solar Power Group but the fast development of this new market for CSP will only succeed as the costs come down significantly. Last week’s announcement by GDF SUEZ and Solar Power Group of their plans to develop ...

Coal-fired power on the way out?
The past two years have witnessed the emergence of a powerful movement opposing the construction of new coal-fired power plants in the United States. Initially led by environmental groups, both national and local, it has since been joined by prominent national political leaders and many state governors. The principal reason for opposing coal plants is that they are changing the earth’s climate. ...

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 ...

Toxicity of sediments potentially contaminated by coal mining and natural gas extraction to unionid mussels and commonly tested benthic invertebrates
Sediment toxicity tests were conducted to assess potential effects of contaminants associated with coal mining or natural gas extraction activities in the upper Tennessee River basin and eastern Cumberland River basin in the United States. Test species included two unionid mussels (rainbow mussel, Villosa iris and wavy‐rayed lampmussel, Lampsilis fasciola, 28‐d exposures), and the commonly ...

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 ...

Closing the door on building new coal-fired power plants in America
Community opposition, legal challenges, and financial uncertainty over future carbon costs are prompting companies to rethink their plans for coal. Since the beginning of 2007, 95 proposed coal-fired power plants have been cancelled or postponed in the United States--59 in 2007, 24 in 2008, and at least 12 in the first three months of 2009. This covers nearly half of the 200 or so U.S. coal-fired ...

Cleaning Up Gasification Syngas
Documento sin título Introduction By definition, gasification is the art of changing a non-gaseous substance, such as a liquid or a solid, into a gas. By this definition, processes such as combustion, anaerobic digestion and pyrolysis would be classified as gasification. However, in today’s world, gasification is defined as any process, which produces a “synthesis gas” or a ...

Generation using gas-fuelled engines in South Africa – an overview
Most gas engines are Otto cycle spark ignition internal combustion reciprocating engines using natural gas as the primary fuel. Smaller models utilise stochiometric combustion while the larger engines are lean burn engines with pre-chamber ignition systems. The engines are coupled with packaged generator sets, cogeneration and, even, trigeneration units to optimise energy utilisation in the fuel ...
