    Native Hawaiians have long expressed frustration with the Puna Geothermal Venture plant since it came online in 1989; they say it is built on sacred land. Goddess of fire, Pele, is believed to live on Kilauea volcano, and
    the plant itself is thought to desecrate her name. Other residents have voiced concerns over health and safety.

    It'll take industrial quantities of gin to placate Pele this time...

    A reactivated fissure from Hawaiiís Kilauea volcano threatened the Big >Islandís geothermal plant with a new lava flow Tuesday, which could
    trigger the release of toxic gases if it reaches wells at the plant,
    Hawaii officials said.

    Seems like every square inch is "sacred land" ...

    In any case, looks as if the plant will be buried in
    lava. Last photos showed it lapping at the doorstep.

    Geothermal always SOUNDS good, but it never
    performs well in the real world. Rock is a pretty
    good thermal insulator, so once you suck a little
    heat out of it then it takes a long time for that rock
    to re-warm to useful levels.

    Geothermal may be best not at making electricity
    but instead for producing large volumes of somewhat
    heated water. A huge amount of electricity/gas is
    used just to heat up water for various purposes. If
    the earth can get it almost as warm as you need
    it to be ... huge savings.

    Not so much the form of energy, but the centralized aspect.
    Better to extract power from 60,000 small holes than one big hole.

    U.S. geothermal heat pump shipments This statistic
    represents the total number of U.S. geothermal heat pump shipments in
    2008 and 2009. In 2008, a total of 59,360 geothermal heat pump units
    were shipped. These shipments had a rated capacity of 416,105 tons.
    -- https://www.statista.com/statistics/219199/total-shipments-of-geothermal-heat-pumps-by-type-and-capacity/

    There are three types of heat pumps: air-to-air, water source, and
    geothermal. They collect heat from the air, water, or ground outside
    your home and concentrate it for use inside.
    ...
    Geothermal (ground-source or water-source) heat pumps achieve higher efficiencies by transferring heat between your house and the ground or
    a nearby water source. Although they cost more to install, geothermal
    heat pumps have low operating costs because they take advantage of
    relatively constant ground or water temperatures. Geothermal (or ground
    source) heat pumps have some major advantages. They can reduce energy
    use by 30%-60%, control humidity, are sturdy and reliable, and fit in a
    wide variety of homes. Whether a geothermal heat pump is appropriate
    for you will depend on the size of your lot, the subsoil, and the
    landscape. Ground-source or water-source heat pumps can be used in more
    extreme climates than air-source heat pumps, and customer satisfaction
    with the systems is very high.
