Many people think coal represents a bygone way of life and that America has moved on to safer and cleaner energy sources. On the contrary, coal provides roughly half the nation’s electricity—far more than any other source of power—and our coal use has nearly tripled since 1960. Our coal use will continue to expand if the power industry succeeds in building the many power plants it has proposed for construction.
Coal’s proponents claim coal power is cheap. While the direct price of electricity from the nation’s aging fleet of coal plants may be low, it doesn’t reflect the staggering and lasting costs of coal-related air and water pollution, mining accidents, permanently altered landscapes, and, most importantly, climate change. Even the newest proposed plants – which would cost far more than existing plants—would have major impacts on air and water quality, and almost the same mining and climate impacts as existing plants.
Technology is evolving that has the potential to substantially reduce coal’s contribution to global warming by capturing carbon emissions before they are emitted. This technology could become an important part of the battle against global warming, but it remains to be seen whether it will work at a commercial scale and at what cost.
Meanwhile, a 2009 UCS study found that we can dramatically reduce our coal use—and all the environmental and social costs associated with it—while saving energy consumers money with policies that aggressively promote energy efficiency and renewable power.
How Coal Was Formed
Coal was formed when dead plant matter submerged in swamp environments was subjected to geological forces of heat and pressure over hundreds of millions of years. As time went by, the plant matter evolved from moist and low-carbon peat, to coal, which is much higher in energy and carbon content. Coal itself has a wide variation in properties, so it is categorized into 4 ranks—lignite, sub-bituminous, bituminous, and anthracite—in order of increasing carbon and energy content. Most of the coal burned in U.S. power plants is of the bituminous or subbituminous variety.

Coal of all types can vary widely in the amount of sulfur contained. These differences are determined by the conditions under which the coal formed. Low-sulfur coal deposits formed in a freshwater environment, while those containing higher proportions of sulfur developed in brackish swamps or marine-influenced environments.[1] In the United States, the sulfur content of coal resources varies along geographic lines, with most of the eastern coal containing high levels of sulfur, and the younger western coal containing much less.

Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

2. WHAT IS MOUNTAINTOP REMOVAL MINING? (MTR)
This is a form of surface mining where the top of a mountain,
hill, or ridge is blasted away with explosives to access coal.
In just months, MTR can undo what geological processes took
millions of years to build.
It changes the landscape permanently.
MTR is harmful to humans as well as the environment.
The mining sites range from Ohio to Virginia. It occurs most
commonly in West Virginia and Eastern Kentucky, the top two
coal-producing states in Appalachia.
3. STEP ONE: CLEARING
Each step of MTR is harmful to the environment.
Clearing is where the entire mountain is deforested.
The resulting lumber is either sold or burned.
MTR has destroyed part of the most biodiverse forests in North America.
An estimated 800,000 acres of mountain forest have been leveled by
these operations.
4. STEP TWO: BLASTING
Once the area is cleared of trees, the miners use explosives to
blast away the rock and subsoil.
This is the most harmful step.
The explosions expel dust and rock into the atmosphere, which
can settle onto nearby private property and cause disturbances.
Dust from the explosions may contain sulfur compounds, which
is corrosive and poses a risk to human health.
According to a study in 2011, "the odds for reporting cancer
were twice as high in the mountaintop mining environment
compared to the non mining environment.”
5. MTR is a huge risk factor for lung cancer.
Adult hospitalization for chronic pulmonary disorders and hypertension are
also elevated as a result of county-level MTR.
Counties located near mountaintop mining areas had higher rates of birth
defects for the circulatory/respiratory system, the musculoskeletal system,
the central nervous system, and the gastrointestinal system.
These defect rates were more pronounced in the most recent period studied,
suggesting the health effects of mountaintop mining-related air and water
contamination may be cumulative.
6. STEP THREE: DIGGING
After the mountaintop has been exploded, the debris must be moved.
Coal and debris are removed using giant machines called draglines, which
stand 22 stories high.
Draglines can cost up to $100 million, but are favored by coal companies
because they displace the need for hundreds of miners.
Appalachian coalfields have plummeted in recent decades because of the
switch to machines—“taking the miner out of mining,” as local residents say.
7. STEP FOUR: DUMPING WASTE
Excess rock and soil loaded with toxic mining byproducts are
deposited in neighboring valleys, these are called “holler fills” or
“valley fills.”
Valley fills are responsible for burying more than 2,000 miles of
vital Appalachian headwater streams, and poisoning many more.
As a result, water downstream of mountaintop removal mines
has higher levels of sulfate and selenium and increased electrical
conductivity. These changes in water quality can directly kill
aquatic species, or disrupt their life cycles so severely that their
populations dwindle.
9. STEP FIVE: RECLAMATION
Grass seed is spread in a mixture of seed, fertilizer, and mulch
made from recycled newspaper. The land will then be further
reclaimed by adding trees if the pre-approved post-mining land
use is forest land or wildlife habitat.
Topsoil is supposed to be removed and set aside for later
reclamation. However, coal companies are often granted waivers
and instead reclaim the mountain with "topsoil substitute.”
Over time plants will grow back but they won’t be as strong as
before. Trees often struggle to grow under these conditions.
10.
11. CONCLUSION
These operations are a health hazard to nearby human communities, they
destroy animal habitats, and they destroy mountains which are priceless
and nonrenewable.
All of this for the sake of mining coal; Is it worth it?
In recent years mountaintop removal mining has been declined thanks to
the opposition against it, but it’s still an issue.
