Germany’s wind and solar power generation came to a standstill late last year. More than 23,000 wind turbines ran out of wind and most of the one million photovoltaic systems ran out of sunlight. For a whole week, coal nuclear and gas-powered plants generated an estimated 95 percent of Germany’s electricity.
Apart from a tad of geothermal heat and a wisp of heat from nuclear power generators, every bit of surface energy (including coal and biomass) comes directly or indirectly from the sun. There is no other source of surface heat--- everything else just stores, releases or re-directs solar energy.
The current heatwave in Australia will inflame the carbonistas who will claim it is caused by wicked humans exhaling and exhausting carbon dioxide.
To compete in today’s world we need to score well on resource availability, capital assets, energy costs, tax burden and workforce/management. It also helps to have secure property rights and a sound currency. Today’s Australia scores poorly on all counts.
For at least fifty years, agitated academics have been predicting the end of the Great Barrier Reef. Now international “experts” are also sprouting coral calamity. But despite the alarms, the reef is still there.
