You’ve swallowed the green
propaganda on renewables hook, line and sinker. Wind and solar are wasters of resources. They are net
energy SINKS when all of their actual energy inputs are taken into account.
For instance wind turbines
frequently draw power FROM the grid to maintain themselves. They cannibalise
the grid and have nothing to contribute to the future of humanity. Renewables
salesmen exaggerate the lifespan of wind and solar generators to about twice
their real productive life, especially for wind. Wind turbines are typically
given a theoretical lifespan of 30 years. In practice they are uneconomic to
run (even with their massive subsidies) at 15 years of age on land, and 12
years in the case of offshore wind turbines. This means that their real costs
are actually more than twice their alleged costs, or put another way, their
real production is less than half of what it is alleged to be.
Solar panels lose on
average 2% efficiency each year due to the effects of UV on the solar cells and
physical external degradation caused by their local environment. In dusty
areas, knock off another 25% efficiency (recorded in China and India). In humid
tropical/sub-tropical areas, knock off up to 75% efficiency if they are not
constantly cleaned (moss and algal growth quickly covers the glass panels). In
the hotter, sunnier parts of Australia they are failing at 10 years of age, not
the 25 years that all of their production calculations are based on. Even
operating at their best, solar panels are a very inefficient, lousy way of
capturing a very diffuse source of energy. Coal and gas are concentrated energy
sources.
Renewables’ main
contribution (apart from lining the pockets of their owners) is to de-stabilise
existing fossil fueled grids and make the backup fossil fuel power stations a
lot less efficient. We are forced to run (and pay for) two parallel generation
systems — the unreliable, inefficient renewables one that doesn’t work,
backed up by the coal and gas one that does work. In other words, renewables
effectively waste a lot of energy in their construction and maintenance, in the
excessive powerline infrastructure they necessitate, and in their effects on
the reliable grid suppliers among other things.
Renewables are a dead loss, economically, in reliability,
and ecologically. To say that they are a dead loss is not a cheap shot – it is
reality. The sooner they are ditched, the better off we will all be.
