Concentrated solar power (CSP) has better prospects than wind when it comes to renewable energy, according to a leading investor in the sector.
CSP involves using mirrors to focus the heat from the sun onto water-filled tubes, turning the water into steam that drives turbines. The technology is easily combined with a gas or biomass-fired plant to provide electricity day and night. So far, CSP is only responsible for around 400MW of electricity generating capacity worldwide, but this is rising fast.
