Dear Sir:
Greenpeace highlighted some of the reasons why it would be a dangerous development for Suriname to build a nuclear power plant. In fact, there is no need for such a risky and complex system to generate electricity, when Suriname is blessed with ample sunshine. Using Concentrating Solar Power (CSP), it should be possible to generate all of the country's power needs, and not have to rely on imported expensive uranium, nor have to deal with radioactive waste.
CSP employs the technique of concentrating sunlight using mirrors to create heat, and then using the heat to raise steam and drive turbines and generators, just like a conventional power station. It is possible to store solar heat in melted salts so that electricity generation may continue through the night or on cloudy days. This technology has been generating electricity successfully in California since 1985 and half a million Californians currently get their electricity from this source. CSP plants are now being planned or built in many parts of the world.
CSP works best in hot deserts and it is feasible and economic to transmit solar electricity over very long distances using highly-efficient 'HVDC' transmission lines. With transmission losses at about 3% per 1,000 km, solar electricity may be transmitted to anywhere in the US. A recent report from the American Solar Energy Society says that CSP plants in the south western states of the US "could provide nearly 7,000 GW of capacity, or about seven times the current total US electric capacity".
In the 'TRANS-CSP' report commissioned by the German government, it is estimated that CSP electricity, imported from North Africa and the Middle East, could become one of the cheapest sources of electricity in Europe, including the cost of transmission. A large-scale HVDC transmission grid has also been proposed by Airtricity as a means of optimising the use of wind power throughout Europe.
