Our Photovoltaic Future: The Metabolic Revolutions of the Earth’s History

Our Photovoltaic Future: The Metabolic Revolutions of the Earth’s History

Illustration from the recent paper by Olivia Judson on “Nature Ecology & Evolution (2017) “The Energy Expansions of Evolution”.  Olivia Judson published a very interesting paper this March on “Nature Ecology & Evolution“. It is a wonderful cavalcade along 4 billion years of the history of the Earth, seeing it in terms of five “metabolic revolutions.” It is an approach that goes in[Read More…]

Clean Solar Energy, Brings Light To Kenya’s Villages

Picture a small village somewhere in rural Kenya. Darkness has fallen and there is no light to even go to the fields to relieve yourself. The only succour are kerosene lanterns, that are proven health hazard for the people living in the home. It was several years ago when UNEP, Nairobi, took us selected journalists from around the world to[Read More…]

Renewable Electricity: Falling Costs, Variability, And Scaling Challenges

Renewable Electricity: Falling Costs, Variability, And Scaling Challenges

Costs to utility companies from the introduction of distributed solar PV are somewhat balanced by the fact that added solar capacity helps reduce the strain on electric grids on summer days when demand soars and utilities must buy additional power at high rates. Nevertheless, as more residential and business customers install their own PV systems, revenues to the utility industry are starting to decline.[72] Industry-sponsored studies warn that the trend could eventually lead to a radical transformation of energy markets, on a scale similar to the restructuring of the telecommunications industry following the advent of the Internet and cell phones.
