To people everywhere fed by farmers

Renewables are incredibly destructive to our environment and productive farmland. This is a great documentary from Advance Australia covering how people pushing net-zero like the Greens party are doing huge harm to our environment and ability to feed ourselves. Malcolm Roberts is an elected Queensland Senator under Pauline Hanson's One Nation Party.

The Iron Law of Power Density

By Robert Bryce

The conspiracy against wind and solar is one of basic math and simple physics. The shape and size of energy systems are not determined by political beliefs about climate change. Instead, those systems are ruled by the Iron Law of Power Density which says: the lower the power density, the greater the resource intensity. This can easily be seen in the graphic below, a screen grab from a 2021 International Energy Agency report on the mineral intensity of various methods of electricity generation.

The mineral intensity of offshore wind, including huge amounts of copper and zinc, is shocking: roughly 15,400 kilograms per megawatt of generation capacity. That is roughly 13 times more than the amount needed for natural gas-fired generation (1,148 kg) and six times more than what’s needed for a coal plant (2,479 kg)

What we require is power

A quick primer: energy and power are commonly confused, even by people who work in the energy sector. Remember: energy and power are not the same thing.

Energy (measured in joules, or Btu) is the ability to do work.
Power (measured in watts, or horsepower) is the rate at which work gets done.

As I have said many times, we don’t care about energy. What we want is power. That is, we don’t care what form of energy (oil, sun, coal, or gas) that’s being used to power our car, run our television, or cook our quinoa, we only care that we have the power needed to do the work at hand. Put another way, energy is useless if we can’t make it flow. And the more we can make energy flow, the more power we can produce and therefore, the more work we can do. Writer and polymath Vaclav Smil calls power density the “key analytical variable to evaluate all important biospheric and anthropogenic energy flows.” So, what is it?

What is power density?

Power density is the measure of energy flow that can be harnessed from a given area, volume, or mass. Power density is a measure of how many watts we can get per square meter, liter, or kilogram from a given source. This article focuses on areal power density. Proving why low-power-density sources are the wrong choice for modern society takes only a modicum of effort. What is power density?

Power density is perhaps the most important, and least understood, metric in physics. Power density is the essential metric for understanding our energy and power systems. Indeed, the global history of energy over the last 250 years, from the steam engines designed by Newcomen and Watt to the latest nuclear reactor designs and computer chips, can be grasped by seeing them through the lens of power density.

Corn ethanol, wind, and solar are not only dependent on the weather, they are also cursed with low power density. (About 1 watt per square meter for wind and 10 watts per square meter for solar.) That means like ethanol, they, too, require vast amounts of land. They also require vast amounts of copper, zinc, molybdenum, silicon, and rare earth elements like neodymium. With inflation hitting commodities of all kinds, the mineral intensity of wind and solar is hitting the bottom lines of the big renewable companies.

Land and ocean

The other key facet of the Iron Law of Power Density, of course, is land use. The only way to substantially increase production of wind and solar energy is by seizing more and more land, (or ocean) so they can be covered with more and more steel, concrete, copper, and silicon.

Where have all the caring people gone?

Wind and sun are free. Solar panels and wind turbines are not free. Un-renewables are not the cheapest, they are the most expensive form of energy that eventually will end up on everyone’s electricity bill.
