I have no words
Answer:use renewables
Or we could plant more trees. Nature's carbon capture machines.
Cheap? Nope! A 1,000 megawatt coal-fired power plant will burn 10,000 tons of coal per day. At $50/ton, that would be $50,000 per day. That cost needs to be passed on to rate payers. And coal does not contain chemical energy as chemical bonds don't store energy. Energy is released during combustion when chemical bonds are formed not broken. Coal has pathetic energy density in comparison to uranium. Burning a kilogram of coal yields at most 35 megajoules of energy whereas fissioning a kilogram of uranium yields 80,000,000 megajoules of energy. Combined cycle natural gas--fired power plants release 60% less CO2 per unit of energy than coal. Hydropower can be used when there is no wind or sun as can geothermal energy. So, no, coal is absolutely not needed.
Who were you sponsored by? There is no clean coal.
yes th atmosphere is changing and yes there is global warming but its not gona kill us all in 10 yrs
global warming isn't real can you please stop mentioning it
Also try:

“ The quest for heart healthy methamphetamine
And that, friends, is why we need nuclear energy.
Just stop using coal
Rather than unrealistic and impossible plans for 100% renewable energy this is what we should attempt to achieve in the short term
Global warming is a scam / myth.
What about that blue version of that green radioactiv thing that i forgot the name of
This seems defeatist. This one just assumes we want to burn coal for 80 more years.
by not using coal..?
4:27 Emporio could help with that
A good way would be switching all of our energy to a renewable source and holding the hundred companies responsible for 72% of greenhouse gas emissions responsible
One word harness the atom
2:04 Coal is a pillarman
I like the endings of all ted ed vedios. There is some humorous nerdy lines at the lines. These lines put a little quirky smile and a sense of realisation of what they want to say.


Coal stock


Coal is extracted from the ground by coal mining, either underground by shaft mining, or at ground level by open pit mining extraction.

Languages:

Coal is primarily used as a solid fuel to produce electricity and heat through combustion. World coal consumption was about 7.25 billion tonnes in 2010 The price of coal increased from around $30.00 per short ton in 2000 to around $150.00 per short ton as of September 2008. In early 2015, it was trading near $56/ton.
