Energy for Life

by John Maryon

All life forms depend upon energy. Humans have used rapidly increasing quantities since our early ancestors discovered fire. Today modern civilizations would collapse without an abundant supply of usable energy. Its misuse, however, can create dangers and threaten to destroy the ecosystems upon which life, including our own, depend.
    Our main source of energy is the Sun. A giant fiery furnace, 93 million miles away, in which nuclei of hydrogen under tremendous pressure and temperature fuse together, in a process known as fusion, to form a deuterium nucleus. This is the start of a sequence of events in which protons then collide with the new isotope to produce helium. In accordance with Einstein 's famous equation, mass is converted into energy in the form of intense heat. This chain of events can continue for some seven-billion years until all hydrogen is converted into helium and our star becomes a red giant.
    All existing commercial nuclear power stations on earth operate on the Fission process. Heat energy is created when a critical mass of heavy radioactive elements is brought together, in a controlled manner, to sustain a nuclear chain reaction. The atoms are split apart, which results in the conversion of mass into energy. One major problem is what to do with the highly radioactive fuel rods. Fusion, on the other hand, produces no long-life radioactive waste. For this reason, and the fact that hydrogen is plentiful, nuclear fusion remains the ‘holy grail’ to meet future energy needs.
    The key to successful nuclear fusion lies in the ability to sustain and contain plasma at temperatures of up to 50-million °C. The Soviet Union played a pioneering role in the late 1960s by developing an experimental 'Tokamak' Reactor in which the plasma was contained by a powerful magnetic field. This approach has been adopted as a basis for further research in a number of countries.
    Refined energy in the form of electricity is clean, convenient and efficient at the point of use. Traditionally fossil fuels, particularly coal, have been burned to produce steam to drive turbines for electricity generation. When transmission and thermodynamic losses are added into the equation the overall efficiency is less impressive. The big danger comes from the release of carbon dioxide (CO2) into the atmosphere; carbon that has remained locked in the ground for millions of years is transferred into the environment. Coal has played a major role in providing our essential energy needs for centuries, and we should never forget the skill and courage of those mining heroes who faced danger every day at the coalface.
    Serious situations can arise if energy is used as an economic or military weapon. Nuclear power stations can pose a risk to the environment even under normal conditions – but the unthinkable could result from terrorism or military attack. Currently the Zaporizhzhia nuclear plant is being targeted with Western-supplied missiles by Ukraine armed forces.
    Each day conveys of tankers leave eastern-occupied Syria loaded with stolen oil plundered by US imperialism, oil which should have been used to finance the rebuilding of that war-torn country. The greed and bare-faced robbery of imperialism knows no bounds as it continues to plunder the world.
    Both Nord Stream 1 (NS1) and Nord Stream 2 (NS2) natural gas pipelines were severely damaged by a terrorist attack that is widely held to have been carried out in a special US–NATO operation on 26th September 2022. The action was intended to be the successful culmination of a long-running campaign to stop the supply of cheap Russian gas. Due to a failure however, NS2 could be restored quickly if required. As the supply of cheap reliable Russian gas is reduced to a trickle, large demonstrations are taking place calling for the lifting of sanctions against Russia.
    Despite of massive anti-Russian propaganda by the bourgeois media an amazing event has occurred. At the Oktoberfest in Munich the crowd sang the Russian folk song {Kalinka}. An increasing number, apart from the German Greens, are no longer fooled as they face the prospect of a cold winter and dependence on limited supplies of very expensive US shale gas.
    For decades the USA has been able to dominate the international oil market by controlling price, output and supply. things are starting to change, however. At the recent meeting of OPEC 2, which followed appeals from President Biden to increase oil output and support a selective price cap, the decision was taken to reduce output by two-million barrels per day.
    The days are fortunately numbered for the notorious petrodollar that has supported US domination of world trade and finance. Russia now trades oil not only in roubles but also other currencies such as Chinese yuan and Indian rupees. The replacement of the US dollar will represent the removal of another link in the chains that enslaves the world.
    Until fusion is able to provide an abundance of cheap, clean energy a number of serious problems will remain. Conservation of energy is necessary by avoiding waste and unnecessary use and by improving thermal insulation standards. Importantly, the use of renewable energy is vital to help protect our beautiful blue planet. Such projects can be costly and have a long payback period. This undoubtedly deters capitalist investors who looking for a quick profit would prefer to finance a drive-in junk food outlet. An expanded, fully financed public transport system would cut CO2 emissions dramatically compared with private cars.
    All types of renewable energy have their benefits and drawbacks. Solar power is fine on a nice sunny day but has no output during the hours of darkness. Wind energy has a major role to play but cannot function when the air is still. Hydro-electric power is making an important contribution and can provide great benefit but cannot be applied in flat, drought-ridden terrain. Tidal and wave energy projects can make a contribution, but as with all civil projects great care should be taken to protect nature. The effectiveness of all these measures can often be improved when incorporating pumped storage schemes. The expansion of renewable energy is not helped by the insane, totally unjustified and disruptive attitude of the USA when it attempts to sanction Chinese solar panels on bogus human-rights grounds. It is important to avoid the potential disasters that can arise from fracking projects that can pollute the water table, increase the risk of earth tremors and emit more CO2.
    The most cost effective measures in many cases may come from simple improvements to basic home insulation standards. Amendments to building regulations to improve U-values have improved greatly but further improvements are justified by increasing energy costs. Light-emitting diode (LED) lamps have an efficacy far greater than that of an incandescent alternative. We must not forget that many poor people, the victims of capitalism, just cannot afford the high energy costs of today. To avoid shivering in the gloom this winter we must unite and fight to remove the Tories and redistribute the wealth of the idle rich that they represent.
    Common sense and reality are factors far removed from the collective stupidity and blinkered obsession of most European leaders today. They are apparently still unaware that they have fallen into a trap, set by the USA to destroy their industries and economies, by imposing sanctions against Russia that have backfired. Energy prices would fall by at least 70 per cent overnight if the full potential of Nord Stream 2 could be realised and negotiations are started to end the Ukraine tragedy.
    Hydrogen as a fuel has a number of attractions. It is the most abundant element on earth and when burned as a fuel produces water as a by-product. An alternative to burning the fuel is to convert its energy into electricity directly in a fuel cell. Electricity is generated through an electrochemical reaction. Cars are becoming available in which a fuel cell replaces the drive battery. The infrastructure, however, is not in place to store and dispense hydrogen. Whilst the emissions of such a vehicle would be almost zero, the same cannot be said for hydrogen production itself. The usual commercial method is to extract it from natural gas, which is costly and produces CO2. Another method is to use electrolysis but that requires electricity.
    I have attempted to outline the chief physical considerations for a wide range of fuels used to meet our energy needs. Long-term security without pollution requires far more than relying on technological advances and leaving it up to the 'market' to decide. It requires political policies based upon a scientific, fair and objective analysis of the challenge. It requires a Marxist approach to apply the socialist planning, public ownership of natural resources and democratic control of the mechanisms of distribution to ensure a clean, secure, safe and affordable provision.

The New Communist Party campaigns for the following measures:

• Full Public Ownership of all natural resources and energy companies.

• A total ban on fracking.

• Restore rural bus services.

• Investment to expand the rail network and replace all diesel services with electric.

• Full Public Ownership of train and bus services.

• Greater investment into land and off-shore windfarms, solar power and tidal power.

• Planting trees and creating more green spaces.

• Make all products and packaging recyclable.

• Opposition to the evil intrigues, exploitation and naked aggression of imperialism.
