Waiting for the Climacteric: or, the Return of the Greentard

...I want to broach some wider energy-related issues with the help of two acquaintances of this site, before narrowing the scope to agricultural energy in a future post.

Another Failure of Scientific Peer-Review: a Completely Wrong Paper on the Energy Return of Photovoltaic Energy

Theoretically, whatever is published in a scientific journal should go through a rigorous review process that ensures that it is correct and reliable. Unfortunately, it doesn't work that way.

Five Billion Years of Energy Supply: the "Stereosphere" and the Upcoming Photovoltaic Revolution

Both the biosphere and the stereosphere use solar light as the energy potential necessary to keep the metabolic cycle going and they build-up metabolic structures using nutrients taken from the earth's surface environment.

The Solar Transition

Although futurists aren’t supposed to make predictions, the notion that our energy system is switching much more quickly than expected from fossil fuels to renewables, and that solar energy will be at the front of that change, suddenly doesn’t seem so controversial.

The Global Energy Transformation and Innovation: the Case of Solarcentury and Sunstation

The solar revolution will continue to unfold, meanwhile, and the better that innovation teams in the clean energy industries deploy their design magic – in the broadest possible sense of that word – the quicker it will all accelerate.

The Real EROI of Photovoltaic Systems: Professor Hall Weighs in

The EROI of our various energy options, and its associated issues, may be the most important issues that will face future civilizations.

But What's the REAL Energy Return of Photovoltaic Energy?

According to a recent, comprehensive study of the scientific literature (1), the average energy return on energy invested (EROEI) of the most common photovoltaic technology (polycrystalline Si) is 11-12. A far cry from the legend of the "EROI smaller than one" that's making the rounds in the Web.

How to Get your Apartment Off the Grid

The typical solar PV power installation requires access to a private roof and a big budget. However, wouldn't it be possible to get around these obstacles by installing small solar panels on window sills and balconies, connected to a low-voltage direct current (DC) distribution network?

CCC: UK Wind and Solar will be Cheaper than Gas by 2020

Low-carbon electricity from wind and solar farms will be cheaper than gas and effectively subsidy-free by 2020, says the Committee on Climate Change (CCC).

African Lights: Microgrids Are Bringing Power to Rural Kenya

Small-scale microgrids are increasingly seen as the most promising way to bring electricity to the 1.3 billion people worldwide who currently lack it.
