Amsterdam's world-famous canalside houses will soon be allowed to have visible solar panels on their roofs, much to the dismay of local heritage groups, who say they will be an eyesore.The Dutch capital's tall, thin historic houses dating from the 16th to the 18th centuries are poorly insulated and energy hungry.
Solar panels are already allowed on roofs of protected buildings, so long as they cannot be seen from the street. But now the local council wants to relax the rules further in a bid to make the mansions more sustainable.
