Recent reports state technologies have allowed some markets in renewable generation to be competitive with coal or natural gas.
This could be the beginning of transforming wind power into the baseload power source that coal has been since the early 1900s.
and reduce the dependence on gas, coal and oil.""We all get heat from sun. We feel it on our bodies
#OXYMOD-Cleaner power thanks to mathematics Mathematical modelling has in recent years proven to be a useful and cost-cutting tool for designing and modernising coal fired power plants.
The Oxymod project supported by the European union (EU) Research Fund for Coal and Steel (RFCS) has striven to extend existing combustion modelling capabilities to oxy fuel combustion conditions.
Oxy fuel technology was proposed for conventional pulverised coal fired combustion already in the'80s; however, recent developments have led to a renewed interest in the technology, with the ultimate goal of significantly reducing CO2 EMISSIONS via capture.
An extensive database of oxy fuel and air combustion trials in gas-and coal fired testing facilities has been compiled.
SMARTFIRE was a 42 month Research Fund for Coal and Steel (RFCS) project that greatly enhanced reheating furnace operation,
Fusion power designs aren t cheap enough to outperform systems that use fossil fuels such as coal and natural gas.
when scaled up to the size of a large electrical power plant would rival costs for a new coal fired plant with similar electrical output.
while a coal plant of the same output would cost $2. 8 billion according to their analysis. f we do invest in this type of fusion we could be rewarded
#From coal, cheap quantum dots in one step Chemists have discovered how to reduce three kinds of coal into graphene quantum dots (GQDS) that could be used for medical imaging as well as sensing electronic and photovoltaic applications.
The new process described in the journal Nature Communications allows a measure of control over their size generally from 2 to 20 nanometers depending on the source of the coal.
That involved crushing the coal and bathing it in acid solutions to break the bonds that hold the tiny graphene domains together. ou can'##t just take a piece of graphene
GQDS were derived from bituminous coal anthracite and coke a byproduct of oil refining. The coals were each sonicated in nitric and sulfuric acids and heated for 24 hours.
Bituminous coal produced GQDS between 2 and 4 nanometers wide. Coke produced GQDS between 4 and 8 nanometers and anthracite made stacked structures from 18 to 40 nanometers with small round layers atop larger thinner layers.
Just to see what would happen the researchers treated graphite flakes with the same process
and got mostly smaller graphite flakes.)The dots are water-soluble and early tests have shown them to be nontoxic offering the promise that GQDS may serve as effective antioxidants Tour says.
And coal is $10 to $60 a ton. oal is the cheapest material you can get for producing GQDS

running a fleet of coal fired power plants that have long been the source of cheap electricity. But yesterday, the TVA board of directors voted to shutter eight of those power plants
Federal emissions regulations make retrofitting aging coal plants prohibitively expensive while pending rules means it s unlikely any new coal fired power stations will be built in the years ahead.
So the TVA directors voted to transform the utility into a power provider that will obtain a majority of its electricity from carbon-free sources.
The TVA has not yet set a schedule for the retirement of the coal fired power plants but under the plan approved yesterday,
coal will provide 20 percent of the utility s electricity in the future, down from 38 percent today.
Although they re building lots of coal fired power stations, they re also looking at other ways of generating power.
The modest uptick in coal fired generation was substituting for pricier natural gas, not representative of a return to coal as it often mischaracterized.

when you consider that coal fired power plants generate 1 megawatt and release 2250 lbs. of carbon dioxide. So if a fraction of the 6. 6 billion mobile phone users globally changed to solar it would reduce our carbon footprint a lot.
While the greenbacks involved are a relatively small amount compared to the trillions invested in global oil coal
That approach will reduce the need for high-carbon power, such as coal, and encourage the use of more solar and wind power, according to the statement.

In theory, it could simply increase power generation from traditional fossil fuels such as coal and gas, but stringent, legally-binding carbon dioxide emissions targets mean this is not possible.
Until now, geopolymers have relied mostly on fly ash, a byproduct of burning coal, or blast furnace slag, a byproduct of iron and steel production.
These industrial waste products are available only adjacent to coal fired power plants and steel production facilities, and the world does not produce enough to meet demand for concrete products.
Brown described Mcconnell actions to protect coal interests as risking he health and well-being of America.
The IEA suggested that decreasing use of coal in China and upticks in renewable electricity generation there using solar wind
They attributed much of this projection to decreased reliance on coal in China, which reported this week that overall greenhouse gas emissions for the country went down in 2014 the first such decline in more than a decade.

#New zealand will shut down its last large coal fired power generators in 2018 New zealand electricity company Genesis Energy has announced that it will shut down its last two coal fired power generators by December 2018-a bold step towards the country
the country will no longer be burning coal to generate electricity, and will stop pumping around 1,
600 kilotonnes of CO2 into the atmosphere within three years. ts closure marks the end of coal fired power generation in New zealand,"
*but the move is still a significant step towards a world where burning coal is no longer the cheapest and most reliable way to generate electricity."
"Historically, coal has played an important role in ensuring the security of New zealand electricity supply, particularly in dry years where our hydro-lake levels are said low
Although it would be nice to see governments force coal fired power stations out of business, it actually feels more exciting that coal fired systems no longer make financial sense.
In fact, Genesis Energy Chief executive Albert Brantley estimated in a press release that the company will save around NZ$20 to 25 million (US$13 to 16.5 million) each year by not running the coal fired generators.
The two remaining coal-burning generators are located at Genesis Energy's Huntly Power station in Waikato on the country's North Island.
The power station itself will continue to run on natural gas for the foreseeable future. Over the past year and a half, New zealand has increased significantly the amount of electricity it produces from renewable energy,
and the shift from coal will help us to achieve our ambitious goal of having 90 percent of New zealand electricity supply generated by renewables by 2025."

#Oil and gas companies target coal industry as climate deal comes closer As the global climate deal draws closer,
oil and gas companies are claiming that coal is the major factor that is posing a threat to climate.
they are considering gulp coal's market share in power generation. According to them, natural gas and oil are so much part of the problem.
However, gas produced by many oil companies release about half the CO2 EMISSIONS of coal fired plants and lower levels of air pollution.
Counterstrikes against fellow fossil fuels industries have been resisted by the coal industry. It has opted instead to draw attention to new technologies that improve the efficiency of coal fired power plants or capture their CO2 EMISSIONS.
Many environmental advocacy groups are skeptic behind the attacks of oil-and-gas industry's on coal.
In 2006 the state passed a law mandating that it buy less coal fired energy. The Los angeles Department of Water and Power is now also selling its stake in the Navajo Generating station to invest in clean energy alternatives,
