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.

“We are in danger of winning. But….”  

First in-depth radio interview on The Winning of the Carbon War, on Radio Ecoshock. Covers road to Paris, reasons for cautious optimism, Solarcentury and SolarAid in holistic context as microcosm direct actions in the market.

Solar Electricity Buybacks May Reduce Groundwater Depletion in India

It’s hard to find solutions that confront water depletion, climate change and rural poverty all at once, but an innovative scheme being piloted in the Indian state of Gujarat does just that.

Electricity For All: Daniel Kammen - Part 2  

Second part of a discussion about the prospect of decentralized energy systems supplying clean electricity to the developing world.

How Sustainable is PV Solar Power?

Solar photovoltaic (PV) systems generate "free" electricity from sunlight, but manufacturing them is an energy-intensive process.
