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?
http://www.popsci.com/burning-all-fossil-fuels-could-raise-sea-levels-by-200-feet
"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."

Who's Winning The Battle To Replace Coal?

"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."

Global warming is a scam..its natural fluctuation

Because green energy neither profitable nor stable enough to replenish our needs. You cannot imagine any big industry factory which would work exclusively on green energy - it's just impossible. The best option is, we must destroy some place and build a dam somewhere in order to use the energy of falling water. Of course it will totally wreck up local ecosystem, but everything comes with a price.

There is no legitimate reason this hasn't happened.

You lost me at tax credits and subsidies. Renewables will make when they are worth the money. Stealing from me to give rich people fancy cars and solar panels on their roofs is bullshit.
Kent Coleman
You also didn’t mention how renewables will become even cheaper with time

because is not rentable!!.. yes is amazing clean energy BUT! ofers only 2% rentability. is a SHIT. not working for industry!!..nuclear atomic is future.

The only reason fossil fuel industry gets away with Heynis crimes against humanity is because the American people are too freaking ignorant and sorry to simply speak the truth. There are cures for all diseases and zero point energy devices and they’ve been there for more than 100 years.
Eddie Cook
This idiot is working for the RothChilds. He is full of shit. Do not believe anything he says. We’ve had cars that run off of water for many many decades. The son of a bitch is working for the deep state.

Look at Germany for example. Since they started to implement solar and wind, actual energy share on the electricity bill is only around 20 %, the rest are taxes, renewables surcharges and grid fees and the only reason why their power system didn't fall apart a few times is because they are interconnected to the rest of continental Europe.

It's too expensive. The solar panels and wind turbines themselves aren't so expensive but if you want too have only green energy, you have to have sufficient energy storage or backup. And that's the expensive part. Also you need voltage control, so more on load tap changer transformers or similar devices are needed. You need to bring the electricity from places where it's windy to load centers, so you need more power lines etc.

Good luck building a nuclear power plant with battery powered Tonka toys

One reason greed.  Coal is a dying industry.

We represent over 20,000 wind turbine professionals in the industry and from all of us to you that you for making this video. In some cases we find ourselves defending our occupation and trying to explain the overall impact. I have shared this on our channels. I would love to discuss this with you on our podcast some time. Great work.

The real issue is the livestock industry. Animal agriculture produces 51 percent of greenhouse gases and is responsible for 40 percent of rainforest destruction. Fossil fuels are bad, but aren't even close to the level of environmental damage as the meat and dairy industry are.

Ultimately no amount of austerity will make a difference if we don't get our numbers down from the asinine Billions (with a B!) Into the reasonable millions (like less than 100 million). One child per person folks. Time to be responsible and close your legs.
TheRealNoodles
Because the "free market" doesn't deem it profitable so there's not a lot of investment. The market is great only if there's profit involved, but when there is none, it fails to provide. The current coal tech is cheaper to run. Green energy needs lots of capital and investments, right now it is too costly for individual firms to undertake the initiative and also mining companies lobbying governments.
Lucas Goye
Awesome video!! i'd suggest putting the numbers big on the screen so the audience can get the point on the enormous differences between those industries. It's like im hearing the numbers but not the importance of them.
Lesa Be
Real science should be included in your basic rant against coal & gas. Solar Flares & Solar Storms have more influence on earth's temperatures. Great real.

Aerospike Engines - Why Aren't We Using If Green Energy Is So Great, Why Aren't 2 weeks ago   13:39

Over 50 years ago an engine was designed that overcame the inherent design inefficiencies of bell-shaped rocket nozzles, but despite much research in the 60's, 70's and 90's and was to power the replacement for the Space Shuttle. But 50 years on and it still yet to be flight tested. So why aren't we using Aerospike rocket engines?
