    That is a good article. Thanks, Hotel Edison they mention is a great place to eat.

    While natural gas overtook coal back in 2016, now it's [Only registered and activated users can see links. ] as well.
    America's coal industry has already been left in the dust by natural gas. Now it's under immense pressure from the renewable energy boom.The renewable energy sector had slightly more installed capacity than coal in April, according to a Federal Energy Regulatory Commission report.


    That means US power plants can produce more energy from clean sources than coal for the first time in history, according to the SUN DAY Campaign, a nonprofit research group supporting sustainable energy. The breakthrough reflects the plunging cost of solar and wind as well as heightened environmental concern about coal.


    "Coal has no technology path," said Jeff McDermott, managing partner at Greentech Capital Advisors, a boutique investment bank focused on clean energy. "It's got nowhere to go but extinction."

    One must consider the source.

    Wind only works when the wind is blowing, and then between a narrow range of speed. Solar doesn't work at night and does poorly when cloudy, raining or snowing. Neither coal nor NG nor nuclear are bothered by these.

    We have natural gas here. But they won't frack the coal. Our area could really use a boom.

    Coal, gas, nukes, they are all STEAM engines. First patented in 1606. We're stuck in a rut. We need a new way of thinking. There is something we haven't thought of yet. The aliens have figured it out, sure like to have a chat with them and find out what we're missing. They are generating an electromagnetic field somehow, doesn't generate heat or exhaust, silent. What could it be? $billion dollar question.

    There is also another alternative that has been in development for a while - wave motion. Using the power generated by ocean waves out at sea

    Don't forget oil as well. All are used to generate steam, which is pressurized and then can be used to spin the turbine generator. Some other drawback are the quality of the water, which may require a demineralizer to prevent corrosion of the turbine fan blades, by product waste of the steam generation (flyash, nuke waste rod, etc.)

    Always made me smile to see some jackass looking at those tall nuke cooling towers and the steam coming off of them crying about pollution when all it is is water vapor

    As far as energy generation, there is no "one-size-fits-all" solution. What may work for one part of the nation/world, may not be feasible for another part. We should be working on all fronts to improve energy generation and increase the amount of energy derived from whatever source. We need to make solar more efficient, coal more clean burning, natural gas more widely available, etc., etc., etc.

    What we NEED to be doing is decreasing demand; there's no reason not to build buildings in a more energy efficient manner from better materials to more insulation to more efficient windows, HVAC systems, etc.
    There was a pilot project in the Sierras at an old folks retirement village where pipes were dug and planted over 50' deep into the ground. The idea was that the Earth was a constant 65 degrees and the water pumped through those pipes and subsequently through the pipes in the slab would keep their apartments at a minimum 65 degrees, even when summer temps hit the 90s and winter temps hovered in the teens. Initial upfront costs were more, but maintenance was practically non-existent and the other energy demand to keep temps about 72-74 was minimal.

    Another are, especially for California and Nevada (among others) is geothermal - same basic principal as above with pipes going in the ground (on a bigger scale) and using that steam to spin a turbine - the hot pressurized water is then pumped back into the same area from whence it came to get reheated

    Some years ago, I thought if I got rich and bought a waterfront property, I'd build a big concrete wall with generators. Tide comes and goes out, spin the generators and charge the batteries. Our tide is small here, not like France or England where 10 foot tides come in hours. Here our 2-3 ft tides take 6 hours or so, not enough to generate any power. But, I can relax, I'll never be rich, and the gov wouldn't let me build it anyway.
