Indeed, notwithstanding Ontario's emphasis on green initiatives — fuel -
efficient car production, wind power, the closing of
coal - fired generating
stations — climate change is the great battle of the present and future, one that neither Ontario nor any other jurisdiction is doing enough to fight.
There is no doubt that the global
coal fleet is changing as older inefficient subcritical
stations built decades ago in Europe and the US are being replaced by new, highly
efficient plants in emerging economies like China, South and South - east Asia.
While ASEAN is already making a transition away from older, less
efficient subcritical
stations, towards HELE
coal - fuelled facilities, scope exists for even greater gains.
These include more
efficient coal plants and converting
coal to gas, which can be burned more cleanly in power
stations but actually has a higher lifecycle carbon footprint than directly burning
coal.
China is taking important steps to close down smaller, inefficient power
stations but it is also building large, modern and more
efficient (HELE)
coal - fired power plants — new regulations effectively ban subcritical (non-HELE)
coal technology.
«The DLP will push for the retention of our cheap, clean and
efficient coal fired power
stations and look to a more transitional model of using
coal gasification and other clean
coal technologies that would be far less costly to the taxpayer, while producing a secure and solid baseline for our grid.»
By then, we may even have
efficient new
coal power
stations, like the Japanese, Chinese, Koreans and Taiwanese.
In fact, the agency was banning even the most modern, very
efficient, supercritical
coal - fired
stations because their carbon - dioxide emissions are at least 20 percent above the EPA limit.
Supercritical
stations burn less
coal per megawatt - hour produced and so benefit the environment and the electricity consumer.A modern, highly
efficient, supercritical
coal - fired
station with stack gas cleanup is very clean indeed, essentially emitting only water vapor, carbon dioxide and nitrogen.
For the UK to be on track to achieve the emission reductions required by the Climate Change Act, it would have to become as carbon
efficient as France by about 2015; which magnitudinous challenge would require the equivalent of the UK constructing and putting into service about 30 new nuclear power
stations in the next five years, while retiring an equal amount of
coal - fired generation!
Coal burning in power stations is far more efficient than smoky inefficent open hearths and consequently far less particulate carbon gets into the air from each ton of coal bu
Coal burning in power
stations is far more
efficient than smoky inefficent open hearths and consequently far less particulate carbon gets into the air from each ton of
coal bu
coal burnt.
Converting
efficient coal - burning power
stations into ludicrously inefficient, wood - burning power
stations (requiring the destruction of vast amounts of American woodland) isn't going to do that, either.
However, most
coal - fired power
stations have
efficient precipitators and some have sulfur - capture technologies, so the net environmental effect of 10 % biomass substitution (on an energy basis) appears to be negligible.
«A modern, highly
efficient, supercritical
coal - fired
station with stack gas cleanup is very clean indeed, essentially emitting only water vapour, carbon dioxide and nitrogen.
Indeed, some of Australia's
coal plants are still notoriously inefficient: Hazelwood Power
Station in Victoria, for instance, has been ranked the least carbon -
efficient power plant in the world.
In contrast, a
coal - fired electricity generating
station is about 35 percent
efficient.
