Energy predictability

Every year, the International Energy Agency gives an overview of the World Energy Outlook. The 2013 edition can be found here.

However, according to Energy Post, the IEA World Energy Outlook consistently underestimates wind/solar growth.

Energy challenges

How do we make gas supply networks more resilient? This study argues that we need a fair distribution strategy.

Should we build more large dams? This study by Oxford University investigates the real costs of mega-hydropower.

Back to coal? German efforts to go green prove complex (New York Times article).

Environmental impacts

A paper by Evans et al. (2009), comparing the sustainability of different forms of renewable energy: Evans_etal2009_sustainability_renewable_energy.

A paper by Pacca & Horvath (2002) looking at the whole-life greenhouse gas emissions of different types of power station: Pacca_Horvath2002_GHG_Colorado_power_plants

A paper by Pihl et al. (2012) comparing the raw materials required to construct different types of Concentrated Solar Power station: Pihl_etal2012_ConcSolarPower_materials

The new Ivanpah CSP scheme is a “$2.2bn solar-powered bird-scorching project” (according to the Wall Street Journal).

Apparently, mammals such as reindeer avoid power lines because they see them in UV.
