Energy and water are necessary for a sustainable economy and sustainable environment

“If you want to see a good example of how vital electricity and energy are to an economy, look no further than Germany. Since the country has imposed strict restrictions on people gathering, large parts of industry have been harshly impacted. The existence of millions of German people is now threatened.” click here

Unsustainable development is the fruit of political tyranny

“Climate alarmism has always been about tyranny, and taking away your freedom and money.  Now they’re being quite open about it. They want people under house arrest permanently.” click here

“Green New Deal” is unsustainable, turns Brundtland Commission definition on its head

The term “sustainable development” was first coined in 1987 by the Brundtland Commission as “development which meets the needs of the present without compromising the ability of the future to meet its needs.”

Advocating the Green New Deal now in face of the coronavirus pandemic has essentially redefined the term…

“Green New Deal sustainable development sacrifices the lives of people alive in the present while compromising the ability of the future to meet its needs.”

“President Donald Trump criticized Congressional Democrats on Tuesday for using the coronavirus rescue package to push for environmental priorities.” click here

Electric vehicles are unsustainable

“EV’s are hyped as being pollution free. Well, not necessarily so. Its true EV’s have no tailpipes, but the tailpipes are located at the power plants generating the electricity to charge the cars batteries, and at the refineries that provide all the derivatives from petroleum that make all the parts of the EV’s.” click here

Concentrated solar power is unsustainable

“Crescent Dunes is a flop and taxpayers are set to lose $737 million on it, according to a new Bloomberg report. That is even more than the $535 million taxpayers lost on the corruption‐​soaked Solyndra solar project.” click here

The new “green” energy economy is itself unsustainable

“This “new energy economy” rests on the belief—a centerpiece of the Green New Deal and other similar proposals both here and in Europe—that the technologies of wind and solar power and battery storage are undergoing the kind of disruption experienced in computing and communications, dramatically lowering costs and increasing efficiency. But this core analogy glosses over profound differences, grounded in physics, between systems that produce energy and those that produce information.” click here

Low power density of wind makes wind energy unsustainable

Lee M Miller and David W Keith. Observation-based solar and wind power capacity factors and power densities. Environmental Research Letters 13 (2018) 104008.

Power density is the rate of energy generation per unit of land surface area occupied by an energy system. The power density of low-carbon energy sources will play an important role in mediating the environmental consequences of energy system decarbonization as the world transitions away from high power-density fossil fuels. All else equal, lower power densities mean larger land and environmental footprints. The power density of solar and wind power remain surprisingly uncertain: estimates of realizable generation rates per unit area for wind and solar power span 0.3–47 We m−2and 10–120 We m−2 respectively. We refine this range using US data from 1990–2016. We estimate wind power density from primary data, and solar power density from primary plant-level data and prior datasets on capacity density. The mean power density of 411 onshore wind power plants in 2016 was 0.50 We m−2. Wind plants with the largest areas have the lowest power densities. Wind power capacity factors are increasing, but that increase is associated with a decrease in capacity densities, so power densities are stable or declining. If wind power expands away from the best locations and the areas of wind power plants keep increasing, it seems likely that wind’s power density will decrease as total wind generation increases. The mean 2016 power density of 1150 solar power plants was 5.4 We m−2. Solar capacity factors and (likely) power densities are increasing with time driven, in part, by improved panel efficiencies. Wind power has a 10-fold lower power density than solar, but wind power installations directly occupy much less of the land within their boundaries. The environmental and social consequences of these divergent land occupancy patterns need further study.
