Comment: Japan disaster demonstrates need for global ‘energy shift’ Comment: Japan disaster demonstrates need for global ‘energy shift’

The recent environmental and resulting economic disaster in Japan drastically demonstrates the need for an ‘energy shift’ towards sustainable and decentralised forms of energy, which is where solar PV can play a major part.

Getting the balance right in developing countries Getting the balance right in developing countries

Renewable energy can have wide-ranging social and economic benefits for developing countries, as well as contributing to the climate change agenda. But a balance needs to be struck between public subsidies, the charity sector and private investment.

CSP: Developments in heat transfer and storage materials CSP: Developments in heat transfer and storage materials

Photovoltaics (PV) is the dominant solar technology with more than 12 GW installed in 2010 alone, but PV (not to mention wind power) has inherent limitations of intermittency. This gives CSP a distinct advantage, and current advances in heat transfer and storage could increase the implementation of CSP as a significant renewable resource.

Solar thermal technology update Solar thermal technology update

Part one: The collector. At the heart of every solar thermal system is a collector, which traps heat by absorbing sunlight. Matthias Rommel, Peter Kovács and Korbinian Kramer look at the various designs of collectors on the market today, and discuss performance evaluation, state-of-the-art technology, as well as potential future developments.
