Welcome to the future. It’s year 2050 and Scotland is now powered completely by“clean”energy.

Homes have entire roofs made of solar materials, rooms are kept warm by wallpaper, and people go to and from work in electric and hydrogen( 氢) cars.

Oil is still being found in the North Sea, but it’s not now only used to keep aircraft flying. And a new 500---mile underwater link with Iceland has been built to catch heat from the hot springs. There’s still a role for king coal—but the black diamonds are now environment---friendly. 

People will be able to import the electricity they need and export any excess(超过的量) they make through rooftop windmills(风车). New technology will store electricity better and provide it on demand. Heat exchangers will provide heating and hot water.

Harmful carbon dioxide waste is being piped offshore to St Fergus and from there into some of the remaining oil—producing fields to be stored safely without entering the atmosphere. Gas remains the preferred energy source of industry and is now shipped in liquid form. But hydrogen is imported through pipelines from France and from a geothermal (地热的) plant in Iceland.

Hydrogen—fuelled cars have become popular. Electric bikes are common in cities using the new urban two—wheel network. Electric vehicles have become common, and their performances have been improved because of the developments in electrical drive technology like high—temperature super conducting motors. Many people leave their vehicles in a giant park where they can be recharged from the national electrical system . Oilseed rape (油菜) is widely grown to fuel some motors .
