276 How Companies Can Make a Difference for the Environment

the end of 2007, the table includes estimates for capacity installed dur-
ing 2007. Because of the ongoing drop in costs for photovoltaic power
and worldwide push for alternative power-generation methods, we
would expect continuous and significant changes to this type of table.
Note that the Wp/capita (Watts peak per capita) is far higher for
Germany than for any other country. Peak power is given in MW.

Concentrating Solar Power

Solar troughs are the most widely deployed and the most cost-
effective CSP technology. Concentrated sunlight has been used to
