    So what is your evidence to support your claim that my solar system cost $450,000, given that it's already paid for itself over three years ago and has produced over 60 MwH?

    And that's just your personal opinion and superiority complex. And it's your personal choice if you just want to dig-baby-dig.

    Future value - a monthly amount is transferred to a fund used for covering replacement costs at the end of equipment life.

    It's not an opinion, it's what the numbers dictate.
    Energy Density and Human DNA Will Determine Energy Future
    By Vijay Jayaraj

    Though touted as next generation energy sources, solar and wind technologies have been shoe-horned into electricity grids only through government fiat and subsidies. Their failure to be adopted freely by investors and consumers lies in the pathetic energy density of solar panels and wind turbines.

    Energy density is defined as the amount of energy stored in a given unit of mass or volume — a metric that is critical in determining the viability of energy sources. It is typically measured in joules per kilogram (J/kg) for mass, or joules per cubic meter (J/m³) for volume. Often, the expression is in millions of joules, or megajoules (MJ).

    Wood, which was widely used before the introduction of coal, has an energy density of just 16 MJ/kg. Society’s ready adoption of fossil fuels stems from their significantly higher concentrations of energy: Coal’s is approximately 24 MJ/kg; oil, 45 MJ/kg; and natural gas, 55 MJ/kg. In an entirely different league, nuclear fuel, depending on the type, has an energy density of about 4 million MJ/kg and will certainly be used extensively as society progresses throughout the 21st century and into the next.

    The lithium-ion battery is considered important to compensating for the appallingly poor reliability of wind and solar. However, most commercial scale batteries have an energy density of less than 1 MJ/kg, orders of magnitude less than wood.

    Hydrogen, a supposedly futuristic fuel, has just a third of wood’s energy density.

    As one would expect, solar and wind fall short in comparisons of power density, which is a measure of how much energy is produced. In terms of land use, solar and wind put out 5-20 and 2-3 watts per square meter of land area where a natural gas power plant generates 1,000 watts. . . .

    And when our coal and gas and uranium reserves are used up, the power plants produce zero watts for AI. And the sun still shines and the wind still blows even if you just want to dig-baby-dig.

    We have enough to last several centuries.

    And the AI will happily live on as global warming increases.

    Warming is beneficial. The big problem looming is the next ice age.

    That's just your personal opinion. And I'm sure the AI won't mind it.

    So what relevance is that to me? And doesn't change the fact that my power bill is less than $200 per year, and that my daughter charges her EV with their solar system.

    My opinion backed up by the historical record.

    It has 100% relevance to any owner of solar equipment. Your monthly bill is low because you have not accounted for the fact that your personal equipment must be replaced.

    So what!!! That applies to all electrical equipment. And it has 0% relevance to us if my solar system and my two daughters' systems last for 25 years.

    What relevance is that, given that all my neighbours have roof top solar systems too?

    Eventually people will catch on and change the system to stop your freeloading.

    That's your issue, not our's, since we have plenty of sunshine, and don't have a superiority complex. And the roaring forties blows all the time.

    You own your own equipment. Consumers hooked to a grid pay a small portion of their bill into a fund used to replace power plants in the future. You foot the entire cost of replacing your own equipment. You haven’t accounted for ghat.

    Freeloading affects everyone by distorting the free market.

    The Green Energy Con is money laundering for the left. It's also the vehicle for the degrowth nutjobs.

    Clean Energy Benchmark Is Natural Gas

    'Bloomberg Intelligence's research shows data centers, buildings filled with servers and other computing equipment for data storage and networking that supports operations and artificial intelligence (AI), could be responsible for as much as 17% of all U.S. electricity consumption by 2030.'

    'One data center can require 50 times the electricity of a typical office building, according to The Department of Energy. As America wrestles with its future energy needs, this indisputable fact remains: Natural gas is the affordable, reliable and clean energy source that should serve as the benchmark by which all other energy sources are measured.'

    Consider:
    • 'Carbon dioxide emissions from electricity generation have declined 61% due to increased use of natural gas over other sources like coal, according to The American Gas Association.
    • The restarting of coal plants underscores the real issue, which is the need to build more gas-fired power plants fairly soon.
    • U.S. utilities and investors plan to add 133 new natural gas-fired power plants to the nation's grid, according to S&P Global Market Intelligence data, by 2030.
    • Renewable energy sources can't keep up with our growing energy needs.'
    This isn't impressive to the Climate Cult because they actually don't give a crap about CO^2

    So what relevance is that to us?
