Coal
A significant portion of total global carbon emissions are from electricity generation - coal, specifically, accounts for up to one-third of global carbon emissions. So to decrease carbon emissions and thus possibly stop extreme climate change from occurring, coal should be phased out.Consequently, in April 2008, James E. Hansen said "We need a moratorium on coal now...with phase-out of existing plants over the next two decades."
This course of action is being undertaken by several governments. Germany is an example of a country that is phasing out coal Solar and wind are major sources of energy and renewable energy generation, currently around 15%, and growing. Coal is still a source of power in Germany, but it is gradually being replaced with renewable energy. Globally, coal is one the largest sources of energy in the world. During 2006, 27 percent of the world's primary energy is generated from the burning of coal. As a way to phase out coal, a few countries, in which coal is primary source of energy, have enacted legislation to prevent the construction of any new coal facilities and to close operating coal fired facilities. Also in several such countries, initiatives have been started to support the viability of the renewable energy industry to replace decommissioned coal facilities. However, many other countries, such as the United States and Great Britain, but especially China, increased coal production to aid their economic advance. Both China and India have large reserves of coal, but relatively little oil and natural gas, and are heavily dependent on coal for electricity generation. According to Scientific American, the average coal plant emits more than 100 times as much radiation per year than a comparatively sized nuclear power plant does, in the form of toxic, radioactive fly ash.
Some believe that coal should not be phased out and that clean coal technology is the way all emission from the burning of coal can be restrained. But the renewable energy infrastructure, unlike unproven carbon-capture technology, is being deployed now. Some environmentalists and climatologists support a phase-out and criticise clean coal as not a solution to climate change, while entrepreneurs promote improved regulations and modernised technology. Others point out that such a policy would affect developing countries most seriously because of the scarcity of other fossil fuels.

Famous quotes containing the word coal:
“Mr. Christian, it is about time for many people to begin to come to the White House to discuss different phases of the coal strike. When anybody comes, if his special problem concerns the state, refer him to the governor of Pennsylvania. If his problem has a national phase, refer him to the United States Coal Commission. In no event bring him to me.”
—Calvin Coolidge (1872–1933)
“Writing is to descend like a miner to the depths of the mine with a lamp on your forehead, a light whose dubious brightness falsifies everything, whose wick is in permanent danger of explosion, whose blinking illumination in the coal dust exhausts and corrodes your eyes.”
—Blaise Cendrars (1887–1961)
“This island is made mainly of coal and surrounded by fish. Only an organizing genius could produce a shortage of coal and fish at the same time.”
—Aneurin Bevan (1897–1960)
