Energy: A world without fossil fuels?

Fossil fuels have powered the UK for over
400 years and are predictable, reliable sources that supply our energy just when we need it. Today, coal, oil and gas provide 85% of our
energy. But these sources take millions of years to
form and we’re using them very quickly. What’s more, burning them produces carbon
dioxide so if we continue to burn them, we risk dangerously overheating the earth. Imagine a world without fossil fuels. Nuclear and renewables are the 2 remaining
options. Today they provide 14% of all our energy. Nuclear power stations harness energy from
splitting atoms to boil water and produce steam. This steam then operates a turbine, which drives a generator to produce electricity. About 7% of our energy is generated from nuclear power. Nuclear is reliable and predictable. But unlike fossil fuels, it doesn’t produce
carbon dioxide so we could continue to use it long into the
future. If we build at least 60 large nuclear power
stations, we could generate all the energy we need. But nuclear power stations produce radioactive
waste that’s difficult to store. And it’s hard to adjust their supply of power
flexibly according to how much we need. In the next animation, we’ll explore renewable

  1. "These fuels takes millions of years to form and we're burning them very quickly"Last I heard we had over 300 years worth of known coal reserves in the UK – although it's cheaper to import it from abroad where they can just scrape it up off the surface. Also recent discoveries of shale gas have massively increased our known reserves. Seems a bit premature to worry about exhausting supplies. The world will be awash with cheap fossil fuels for many decades to come.

  2. Even if we ignore all evidence to the contrary (like the lack of any warming for the last 18 years) and assume that "CO2 emissions risk dangerously overheating the Earth", how can the UK, which emits less than 1.7% of global man-made CO2, have any effect on global CO2 emissions? The annual increase in Chinese CO2 exceeds the entire UK output. Should we bankrupt our country and export all our jobs as a token gesture, just to show "we care" about an entirely hypothetical problem way way in the future?

  3. 1.11 doesn't produce carbon dioxide…….are you fucking sure ! I'm calling bullshit!' Yes it does. It may be lower than coal , but don't lie to me. I'm not stupid!

  4. I recently published a rebuttal to Alex Epstein's book titled "The Immorality of Arguing That There's a Moral Case for Fossil Fuels." At the same time it also rebuts a book by Kathleen Hartnett White of a similar title and proposition.

    It is preposterous to claim that there is anything moral about fossil fuels, and to claim that we owe any debt of gratitude to gasoline/diesel/coal for enhancing our lives. If a debt of gratitude is owed, it is owed to the inventions that utilize various fuels…regardless of what those fuels are. The inventions were all created without consideration to any specific fossil fuel. Internal combustion engines, for example, were created before the invention of either gasoline or diesel petroleum fuel. The steam engine was not created because coal was available.

    The fact is that fossil fuels have been the cause of wars, disease, and ecological and environmental disasters. Every significant war in the past 104 years has been caused by petroleum oil. Tens of millions of people; no, make that hundreds of millions of people have been killed in these wars. To the war dead-toll we have to add the people who have died as a result of the illnesses caused by the use of petroleum oil fuels. Then there's the life-long injuries and disabilities suffered by untold millions more. There's nothing moral about any of this.

    Previous attempts to rebuke Mr. Epstein and Ms. White, such as the one written by Jody Freeman, have failed because the writers have as little understanding of history, fuels, energy, and real solutions as Epstein and White do.

  5. Cold Steam the efficient way to use the sun or composting and rocket stoves as heat sources to produce electricity and or distilled water explained from basic concept to employment. Water boils in a vacuum at 75 F or 24 C
    Two open containers one full of water the other empty connect them at the bottom and water will reach an equilibrium 50 50. If one is sealed except for the connection the other will remain empty because of the vacuum created in the sealed container.
    Gravity will overcome this vacuum if the containers are taller than 34 feet.
    If the tanks are 40 feet tall the tanks will reach an equilibrium of water levels at 34 feet leaving six feet of hard vacuum in the sealed tank. This makes a vacuum pump set we need two of them if we were going to distill water as the cold side open tank is used to collect the distilled water from it as the continuous input of water needs to go somewhere.

    Each sealed tank has four valves three at the top two of those on opposite sides (B&C) one at the very top (D) one at the bottom on the side (A), water-based vacuum pump operations are, Close bottom tank valve A and top tank valve C. Open top tank valve D. Fill sealed tank through top side valve B. Close valve B and D when full. Open bottom valve A.
    This primes the system to let the warm water in that will vaporize and run through the system when you partially reopen valve B (to control flow rate) and open valve C to its fullest.

    For only power generation need one pump set and one vacuum tank so we can have a Hot side and a Cold side one to boil the water and one to have the low pressure/vacuum to draw the steam in through the turbine then the cooling coils then to the tank.
    At the bottom of the cold side, tank is a return pipe with the one way valve to the heat source the one-way valve prevents expansion back to the cold side and as the hot side vacuum chamber is the only outlet for the expanding water and it is drawn by the vacuum the cycle proceeds.

    You can combine the two and get power generation and distilled water keeping the return line from the power generation system will let you switch if you don't need distilled water on a continuous basis in large quantities.
    I am going to make one feel free to make one as well it is open source.

  6. The name "GO-Science" got to be ironic ..

    Nothing scientific about taking the nonsense of Carbon-Dioxide warming the planet seriously ..

    A joke!
