Sorry to contradict you, ABC SCIENCE, but this would not reduce energy consumption, which is a cause of global warming, as entropy. Combustion energy would have to be replaced by an equal quality of electrical energy. My ideas and a shifted climate science paradigm are on my blog martinknox.com
Combustion, geothermal processes, hydro, solar and wind, all produce heat energy (or electricity), plus water vapour, plus carbon dioxide (some). All the heat energy, including that wasted, ends up eventually in the oceans, land, atmosphere or reradiated into space. Energy taken by hydro, solar and wind technologies and their waste, warm the Earth and are replaced from the Sun. Increase of heat energy, or entropy released, in all these processes, is sufficient to explain the reported global warming.
Carbon dioxide is a mere 0.0042% of the atmospheric gases insulating the Earth from space. It does not act as a trace catalyst, like chlorofluorocarbon was explained to decompose ozone. Nor does it entrap infrared energy causing significant heating. To slow global warming, unnecessary energy consumption must be reduced. Part reduction replacing carbon fuels with wind and solar would increase warming.
- Energy use is voluntary and consumption varies between countries.
- Energy use costs natural resources, human toil and expenditure.
- No energy can be recycled to the same use
- No energy sources can be renewed.
- Pollution by combustion of fossil fuels is mostly from heat and water vapour emissions.
- Carbon dioxide does not trap infrared in the atmosphere more than other gases. Causes of any warming and cooling trends are unresolved.
- Thermal pollution can accumulate on Earth.
- Energy consumption is unlimited except by cost and is a status symbol of wealth.
- Energy ends up warming oceans, warms the atmospheric and goes out into space.
- Heat emissions from devices increase entropy (low temperature heat), are unrecyclable and cause warming.
- To reduce global warming, we need to use less energy. Replacing efficient fossil fuel suppliers of electricity with ‘renewable’ supplies will cause more warming, not less.
These answers are theories forming a paradigm shift in climate science, explained in a satirical fiction story.
The reasons are these: warming of the environment; conservation of energy resources; personal economy; disregard of others; helping less advantaged people.
1. Warming of the environment
There are several possible causes of environment warming. Anthropomorphic warming has human characteristics and is caused by or has effects on humans. Causes of global warming cannot be attributed with certainty and are theoretical. There are many causes possible. Human causes could result from various emissions. Reduced carbon dioxide emission has been theorised to have an additional reduced warming benefit. A simpler theory is thermal emissions from human activity enter the atmosphere and oceans and warm them.
By reducing these activities, there could be less warming of the environment. Activities that could be reduced with this benefit are energy conversion, transportation, residential heating, air conditioning, combustion, fermentation, decomposition and respiration.
2. Conservation of energy resources
Reducing use of energy resources of all kinds, fossil fuels, hydro and renewable energy could save them for use in the future, by others. Less withdrawal of solar energy by renewable energy technologies would reduce warming of the environment by their low temperature waste heat, with the Sun’s higher temperatures driving the ‘renewal’, by the 2nd Law of Thermodynamics.
3. Personal economy
Markets are supposed to rationalise supply and demand of energy in competition with others. Monopolies of suppliers and consumers can prevent appropriate responses to emerging depletion of resources and new technologies. Reduction in energy use could be encouraged by governments. Conversely, energy suppliers encourage consumption to maintain their sales. Individuals can be free to reduce their energy consumption, but their role could seem to them small and not worthwhile until leaders espouse this cause in the public interest.
4. Disregard of others
Energy use has not been limited, except by economic and environmental costs. Users have taken as much energy as they want, like oxygen from the air. People in some countries have helped themselves to much more energy than others. Energy ends up, eventually after use, polluting the environment and oceans for others, by the 1st Law of Thermodynamics. Thus some greedy energy users cause more environment warming and more depletion of energy resources, than others, without having entitlement to do so.
5. Helping less advantaged people
Energy consumption has universal value and is a broad indicator of quality of lifestyle differences between nations. Distribution has depended on historical circumstances. Developing countries could reasonably be allowed more growth in their low energy use than developed countries having high energy use. Such allowance could be voluntary, with high energy-using individuals sacrificing high-energy technologies and activities of marginal value to help those less advantaged. Otherwise sharing might have to be mandated.
Please consider these 5 reasons and reduce your energy consumption.
