Renewables not up to the challenge

 Power Line:

The fundamental problem with wind and solar power is that they don’t work. Both generate electricity less than half the time, and this isn’t a question of improving technology, it is inherent in obsolete systems that depend on the weather. As a result, the ballyhooed “green revolution” has fizzled. The Germans, formerly committed to a “green” makeover, are starting to face reality, even if their politicians aren’t quite there yet:

A paltry two percentage points increase in an entire decade: In 2020, only 12.6 percent of global energy demand was met by renewable energies. In 2009, the figure was 10.6 percent. This is the conclusion drawn by the think tank REN21 in a report presented by energy experts on Wednesday.

According to the report, progress is being made in the expansion of power plants that produce renewable electricity, i.e. solar plants, wind turbines, hydroelectric power plants – but fossil capacities are not being reduced. Instead, energy demand continues to grow, eating up the renewables successes.

A two percent increase in a decade, despite trillions of dollars invested, is hardly a “success.” Die Welt has more:

The fact that the share of renewable energy is not growing is bad enough from a climate protection perspective. It is also sobering that the 12.6 percent share of eco-energy is largely attributable to the burning of biomass, i.e., to a type of energy generation that is the subject of much environmental criticism.

“Biomass” is a joke. It largely consists of shipping millions of tons of low-quality trees from the American South to Europe, where they are burned. A great medieval technology.

The second-largest share, 3.9 percent, comes from hydroelectric plants – such as large dams – which are also highly controversial among environmentalists. In the REN21 report, solar and wind power, which are the focus of attention in Germany, together with geothermal energy, are estimated to account for only 2.8 percent of global energy production and are subcategorized under ‘other’.

Wind and solar may have their good days and bad days but that is their problem.  They are not a reliable source of energy.  They are at best a supplemental sources of energy that needs fossil fuels to provide consistent service, especially during extreme weather events.
