Green energy is getting better and cheaper, yet we still largely rely on fossil fuels. Why haven't we switched to solar and wind energy yet?

What Would Happen If We Burned All The Fossil Fuels On Earth?

"A new study published today in Science Advances finds that if we burn all of the remaining fossil fuels on Earth, almost all of the ice in Antarctica will melt, potentially causing sea levels to rise by as much as 200 feet--enough to drown most major cities in the world."

"Coal is losing the battle for the electricity future in the United States. Investment in new coal-fired generating capacity has dried up with its share of electricity generation dropping from 53% in 2000 to 34% in 2015."

Electricity in the United States
http://www.eia.gov/energyexplained/index.cfm?page=electricity_in_the_United_States
"In 2015, coal was used for about 33% of the 4 trillion kilowatthours of electricity generated in the United States. In addition to being burned to heat water for steam, natural gas can also be burned to produce hot combustion gases that pass directly through a natural gas turbine, spinning the turbine's blades to generate electricity."

Atheists are the biggest problem.
James Haywood
Nuclear power is the best power.
Zach Conklin
Even if the fossil fuel industry runs everything with there power and money, we can still all of us come together and protect this earth from any harm.
marbbridges
The reason why they haven't pulled the plug yet because climate change is not real I'm 62 years old if climate change was so bad we would pull the plug back in the sixties and seventies get a grip and study your history
SlipKnotRicky
I say let the people who want Renewable Energy to pay for it, instead of voting to spend other people's money......
fjandgoob
because you have to go bankrupt for the initial investment, and look at the BILLIONS oblow-me threw away to "green" energy co. solyndra was just one
Dutch Flats
Check with Germany, they've installed tons of solar and wind. Turns out they're now actually producing more CO2 than they did before all those renewables? Go figure?
Bill Conger
Sorry but most of what you said is bullshit or fantasy.
Ian Cocking
Gen 4 Nuclear, Molten salt Reactors, Sea water extraction of Uranium, Fusion ITER, Polywell,. The Nuclear Elephant in the room can fix Climate change but don't mention the N word. We will jump through all manner of hoops trying to get Renewable's to work and bankrupt ourselves trying. They only half work now because of Natural gas which is a lousy solution
Vincent Robinette
What you said is true, but the real solution lies in electrical energy storage. That will smooth out the intermittency of wind and even solar, and provide power through the night. It's the perfect solution for allowing baseload plants to continuously run at their most efficient output and, handle peaks in demand. It will also absorb spikes in output from wind farms during wind storms. It will also eliminate curtailment of wind turbines, which reduces their operating costs. The technologies that interest me the most are batteries (other than lithium) flywheel, and capacitors. Where weight and bulk aren't much of a concern for stationary applications, availability, cost, and longevity are. Save lithium for density critical applications like electric vehicles. Lithium and cobalt are too rare to squander on stationary energy storage. With this, renewable energy can expand to meet the growing demand without further expansion of fossil generation, and can pick up the slack from the decommissioning of old coal plants.

I don't know about you, but I hate being lectured by a teenage know-it-all dweeb. Millenialsplaining at its worst.
Ryan Fazal
Because then what’s the point of invading the Middle East
David Parry
*A. ... because the usa is owned by Saudi Arabia, has to suck Saudi nads or no money for the bankrupt usa, and additionally the coal and oil industry in the usa bribes american child-molesters and halfwits... aka 'american politicians'.*
You're welcome.
David Parry
*Many better countries ARE using it, you american simpletons!*
You're welcome, halfwits.

Why is it whenever they talk about CO2 being pumped into the air they still show factory smoke stacks pumping out white "smoke", I don't know for sure in the states but in Canada our CO2 scrubbers take 99% of CO2 created out of smoke stacks and whats left is mostly just water vapor and less CO2 than someone breathing, coming out as a white cloud. Solar panels and wind turbines are very very inefficient solar panels hardly covert any solar power into actual energy we can use, just look at the issues Germany had that they had to find other sources of energy still. More "efficient" solar farms take up huge amounts of land space that could otherwise be used, they also absorb more solar heat into that area which can contribute to rising temperatures.

Wind farms are one of the biggest jokes, most farms that are created actually stop themselves from working since you can only have up to 4 turbines within relative proximity to one another after that they cancel the others out. The area where you get the most use from them is near the water however this doesn't work as seen by Fukushima who is currently going be to removing their turbines, wind turbines require such finite wind conditions to work that its incredibly useless, not enough wind and just a little too much and they have to be turned off, which turning off a wind turbine costs a continual amount of energy to be fed in to keep it off. As well as the huge costs to maintain wind turbines is why Fukushima is opting out of keeping them. So the water doesn't work what about land. Well you have to go in land quite a lot and clear out huge amounts of land from forests and other things that may interfere with its operation, so for this green source of energy many places have to deforest entire areas to put in working turbines. One of the larger issues besides the fact wind turbines kill millions of bird species year they also pose a huge danger to a large area, when a wind turbine breaks down from one of many different ways it can there is not much that can be done about it. The cost to take apart/dismantle the turbine is a huge amount of money and very dangerous, so most often when one is decommissioned it just sits there and breaks down more; once you add a bit of wind to the equation or just too much wind or something going wrong to a fully working turbine you have a large scale issue because while it breaks and falls apart its throwing huge amounts of heavily metal oil and potentially fire for miles around, as seen in the case of a women who lived 20 miles away from a wind farm had a flaming piece of debris from the turbine come crashing thru her house and caused apart of the building to collapse on impact as well as set fire to the entire building.

Hydro dams are the best of eco power systems except for them drastically effecting fish species, if not implemented or regulated correctly it also effects plants and animals as seen from the dam in Africa that caused the desert to expand exponentially for a time due to the new regulated water flow to the land. Dams also require you to flood an entire area behind the dam to have proper flow thru the dam, other than that they are pretty dam good.

Best option that isn't a "eco friendly" power generation is CADU nuclear reactors, because unlike the traditional nuclear reactor Canadas reactors basically run off of dirt for the amount of material it uses and how radioactive it is and can not melt down since we have to keep them warm not cool them down. They don't produce much radioactive waste and are quite efficient for the amount they do use, unlike traditional reactors which do have a huge power out put but are very radio active, dangerous, wasteful, and produce a huge amount of radioactive waste which they can't use but we take dilute and use it perfectly fine. CANDU reactors have so little radiation that its a common site to see the people in around the reactor chambers cleaning etc are not wearing hazmat suits since there arn't really any radiation readings. The most that comes out of CANDU reactors besides power is clouds of white "smoke" which is actually just clouds of water vapor.

Solar is already subsidized through taxes in my country. I'm subsidizing my neighbors who have solar on their roofs. That stinks.

Atomic energy is the only answer.
Ricardo Santiago
Green energy is not great, is very expensive, unreliable and very inefficient, period.

Errors: I made an off hand comment about adding efficiencies in the video without thinking. This is obviously incorrect, but the final calculation does in fact multiply the efficiencies.
