About: How to create cleaner coal - Emma Bryce
I have no words
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

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..?
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
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.
