BARRIERS TO DISTRICT HEATING DEVELOPMENT IN SOME EUROPEAN COUNTRIES Abstract District heating (DH) offers low primary energy demand, high security of supply and small CO 2 emissions. Barriers to DH in the UK, Ireland, France, Romania and the Czech Republic have been compiled through publications and interviews. DH systems require large investments, have negative initial cash flow and long payback time, which obstructs financing. One actor should control DH from source to consumption. If the value chain is fragmented, contracts are required between the links. It increases risks and financing costs, like in the UK and Ireland, where DH is not established. There are few multi- family houses with central heating and it is expensive to build DH networks in built areas. Most French DH systems are operated according to long-term concessions by companies that sell electricity and gas. No strong actor provid...

London History The Romans AD 43- AD 410 The Romans finally invaded Britain in AD 43 from Kent. The Romans lead by Julius Caesar attempted to invade Britain twice before that in 55 and 54 BC but the invasions were unsuccessful. They made their way to the river Thames and sailed up it. The Romans knew it was important to control a crossing point at the river Thames, so they decided to build a settlement on the north bank. Although small settlements had been built on the banks of the Thames, the Romans were the ones who built the first city. They called their city Londinium. The Roman engineers noticed that the point where the swampy river narrowed would make an ideal crossing point, they built London Bridge. Less than 20 years later the native Iceni tribe, led by Queen Boudicca, rose up against the Romans in revenge for mistreatment and burnt Londinium to the ground. The well disciplined Roman army defeated her forces and Londinium was r...

Some of the things you will learn in THE CODEBREAKERS • How secret Japanese messages were decoded in Washington hours before Pearl Harbor. • How German codebreakers helped usher in the Russian Revolution. • How John F. Kennedy escaped capture in the Pacific because the Japanese failed to solve a simple cipher. • How codebreaking determined a presidential election, convicted an underworld syndicate head, won the battle of Midway, led to cruel Allied defeats in North Africa, and broke up a vast Nazi spy ring. • How one American became the world's most famous codebreaker, and another became the world's greatest. • How codes and codebreakers operate today within the secret agencies of the U.S. and Russia. • And incredibly much more.
