Flat-plate solar hot water heaters were indeed sold in newspapers and merchandise catalogs almost 100 years ago, indicating that practical technology for the use of solar energy has been developed for quite some time. Solar-thermal electrical production is not only at the experimental stage but is also being used commercially in various parts of the world. Solar energy is renewable, and technology associated with its use is becoming more decentralized and affordable over time. While solar energy may not be able to completely replace fossil fuels, it can certainly contribute significantly to our energy demands. Therefore, options A, B, D, and E are incorrect.
