Aurinkovoimasta ei energianlähteeksi riippumatta kuinka paljon veronmaksajien miljoonia siihen kaadetaan
(Aurinkovoimala Mojaven autiomaassa)
"Solar power can never produce continuous, predictable low cost power. It must always be supported by expensive power storage systems or by reliable power sources such as coal, gas, hydro or nuclear.
No matter how many millions of taxpayer money is poured into “research”, it can never solve the two fatal flaws of solar power.
Firstly, sunlight energy arrives in very dilute form, and thus needs vast areas of collectors to harvest significant energy. This results in high capital costs and much environmental disturbance. Solar power can light one 75-watt bulb for every card table of collectors (in the middle of the day only). How many card tables do we need to run the trains, factories, fridges, homes, heaters, hospitals and tools of a big city?
Secondly, the solar energy produced during daylight hours is constantly variable and unpredictable, and zero power is generated at night. As a result, solar power farms seldom produce more than an average of 15% of their rated capacity over a year and as low as 1% for a day or so"
